Thank you for taking the time to make that video. I got an identical jack that recently quit working from my grandfather. The rebuild is going to be easier than I expected with the help of this video.
Realize the video is four years old, but this majorly helped me to do basic maintenance / repair on a 70's Orange and White jack that looks very similar. Dad has had it since before me; the release valve stopped releasing. Got it apart, cleaned, and back to working with new fluid. Thank you for your detailed descriptions and hard work :)
@@Dopamine1217 Maybe maybe not. Depends on what failed. I didn't have to pull the hydraulic ram apart, but guys sometimes do. GarageJournal has a really good long thread about how to rebuild Taiwan jacks - I'd start there. In my case, replacing a handful of orings + new fluid got it working again, although it will lose an inch a day or so under load - I never use it without jackstands.
I just rebuilt my 20+ year old Sears 3 ½ ton floor jack. This video helped me understand what I had to do. My main problem was with the big seal at the tip of the shaft for the piston. I didn't mess with all the other smaller o-rings and screws with ball bearings underneath. Thanks for putting this together. Now I have my old heavy jack that I use again. Safety thought: when I first noticed that my jack was no longer working well, I had just lifted up my car to change a wheel. When I went back 5 minutes later to put the new wheel on, I saw that the rotor was very low on the ground. I don't even want to think of having someone (me?) working under the car while this happened.
When I was working after school in a garage (long ago) an old mechanic told me to never trust a hydraulic jack. He said to always use jack stands and pointed to a car across the shop floor which was up on a floor jack and no stands. Amazingly, the jack suddenly lost pressure and the car fell back onto the floor. Thankfully nobody was under it. That stark lesson has remained with me.
I recommend using a thin coat of the hydraulic jack oil on all o-rings and seals as a assembly lube. Do not contaminate the hyd. system with other products. Thanks
one of the best videos I have ever watched you did not tell me about your wife your kids the grass how long you've had the Jack when you bought it none of this other stuff you were right to the point great video. Easy to follow along and mine works perfectly after the rebuild thanks.
28 years ago I got a harbor tool and equipment jack just like that and a set of 6 ton stands from my parent's as a Christmas present. As a matter of fact I just got done using it and put it away about 10 minutes ago. Had my Altima up on stands and took the tires and rims to Walmart for a new set of tires. Best gift I ever received! She seems a bit slow so I'll be doing this rebuild in the near future. Thanks for sharing. It took about 3 beers to get through this video BTW.
Finally, a real jack rebuild and not just a Krylon paint job. Thanks. Also, thanks for showing all the newbies what it means to put packing under a workpiece held in a vise.
Great video. I once bought a similar floor jack like yours dirt cheap because it leaked down, the fix was very simple, ran a magnet down into the seat of the check ball, pulled out a tiny metal shaving. Jack worked fine after. Easier and cheaper to try the magnet fix before rebuilding
Great video. I've got an old Sears jack I got from my grandpa's garage after he recently passed. It hasn't worked in about a year, same issue as yours. I've got the rebuild kit coming and am confident I can do it after watching your video. Thank you!
This randomly popped into my feed, and I'm really glad it did, because it never occurred to me how easy it was to rebuild one of these jacks. I've got an old Harbor Freight 3-ton that isn't working anymore, and it may be cheaper to repair than replace, plus I've got an old aluminum Harbor Freight model that doesn't hold or pump up anymore - hopefully I can find a rebuild kit for both of those! Thanks for the inspiration!
Excellent video. You're right in that the outer seals are wipers to keep contamination from getting inside the pump, so they are installed with the cup facing out. I have the same jack and I'll be rebuilding it this weekend. Thanks for the tutorial.
Hi Great video. I have an Australian made APAC 241v 1500kg jack that I brought when I an apprentice in 1973 used every now and then has paid for it self over and over . I had it reconditioned in 2010 for $242.00 by a jack reconditioning guy who had a huge workshop at home in Melbourne Australia . I know it was a lot but I saw some of the stuff that was for sale then and even now ,can't compare to my old jack . Plus when I went to pick it up we were there for over an hour looking at all his engineering gear and he showed us other projects he was working on . Had a Great time with my young son who was with me then.
Thanks for the video. I have my father's 5 ton bottle Jack that is probably 45 years old. The local cylinder shop refused to rebuild it. "It's cheaper to buy a new one" was their answer. Now I can rebuild it myself. Thanks!
Thank you for the great info! I found an old jack on craigslist recently just after watching this video! I am saving so much money and its fun to rebuild it as well! Cool stuff!
I picked up a 3 1/2 ton Craftsman on the side of the road for free. In real good shape. It jacks up fine for changing tires, but drops in about a half hour. Going to rebuild it this winter, some cold snowy day. LOL Thanks for the preview of what I'm in for!
Your video made me go out and clean my floor jack-It’s a Sears Model too and identical -I bought it in1983 and has lot of sentimental value-lol!!!...great work and video!!!!!!!!
I have a Sears 2 ton floor jack from 1989. Still works but now I have the confidence to rebuild it thanks to your video! Oh...and a large crescent wrench has saved my ass more than once!!
that BLUE PLUNGER WAS ALL THAT WAS NEEDED !! the black one was whooped fyi . thanks for the video iwas very good I have a bunch od Lincoln and Walker jacks from the 70's and have rebuilt them and this is the type of info our kids need. you know our 30 and 40 year old kids. Thanks again.
Joe Shabidu Keep rockin', Every repair is a confidence builder, and you're never done. Recent additions to building skills- trigger spring on a top-break revolver, patch plastic ends of radiator with epoxy. The stuff was broke anyway, I dont think much more harm could be done, if the fix didn't work. Best wishes!
The beauty of the internet is in my opinion, someone somewhere in the world will have an answer for something. Who knows what could be solved in any field, thank you everyone who takes time to post their version of things
This actually helped me get my jack working again, somehow. Mine is completely different but just watching someone take it apart helped give me an idea. I realized I had opened something I shouldn't have and a part fell out. I took another look and sure enough I found a tiny piston lodged in a crack in the jack. Used the magnet trick with an awl to get the piston and spring in the correct position. Jack is now working good as new. The oil was low which was I took it apart in the first place but I opened the wrong part and the manual doesn't actually tell you what to do. The manual even labels every part except the holes... go figure.
Excellent video. My old floor jack leaks down all the the time so as a consequence it has sat in the corner of my shed for 15 years. I'm going to go to a bearing shop and see if I can get the seals to rebuild it. Looking forward to this project and thanks very much!

GREAT VIDEO !! Your easy method of step by step is great to follow, your trouble shooting possible issues is spot on, camera work was acceptable and your explanation of parts excellent. Ordered this style of jack from Sears Roebuck Co in 1970 and shipped to Germany where we were stationed. Had a little VW bug I used as my work car. I could jack the car up, pull the little 31 HP motor out, carry it inside our government quarters into the kitchen, drain the oil out into a pan ( for PROPER disposal ), wash the oil screen out with gasoline outside, put the motor back into the car, affix the throttle cable and generator cable, pull out the jack stands, let the car down, refill the oil, start it up, pack the wife in the passenger seat and head to the Commissary on base for a grocery run all in 45 minutes. I got my money's worth out of this jack, every penny. The jack is setting in my shop today under the work bench and THANKS to this vid I'm going to rebuild it next week for sure. That little jack was made like a German tank and heavy like one too. Jacks like that are well worth the rebuild kit cost to repair. I'll have to look on the jack to see where it was made. Don't know if Sears bought Japan or China made then but I might be surprised. Thanks for a GREAT instructional video. You rank way up the list for a professional quality job here.
Nice job on the rebuild. I have been in the automobile repair business for over 45 years and still use my floor jacks. Never had to rebuild them but was always curious on what was inside of one. I found this video extremely interesting. Nice catch on that pressure regulator. I might guess that's the safety valve to keep from overlifting the jack and damaging it. But the process seemed pretty simple that you did here. I also liked your style of systematically rebuilding each section and also I liked the fact that you put that paper towel down in that cavity to keep trash out. You're truly a professional. Thanks again for taking your time to make this video. Nice job!!
Great video. Auto body tip. When using hammer hold index finger pointed up onto the handle towards the head of the hammer. Gives much better control of your grip and aim while striking. Give it a try.
I have a "Big Lots" Chinese jack from 1980, $29.95, WAY before Harbor Freight, with the same leaking oil problem. You have inspired me to try a repair later on...thanks! I'm rebuilding power window motor gears now, all learned on TH-cam.
Great job .. I use to rebuild these jacks back if the 70s & 80s, and let me say they were good jacks . The crap coming out of China , well you know . Hine Warner was a good Jack, Sears actually sold this jack in different lifting capacity with the SEARS logo . Also Lincoln was a vere reliable floor jack, same as the Walker well back in the 50s . This junk thats available today is use it and throw it away when it falls .... The old school of rebuilding things are a thing of the past anymore.... Thank you for posting this video, brought back many memories...
Nice work I have my Grandads jack that I used to work with him in the shop when I was a Kid. I have had it since he passed away and it needs rebuilding. My wife always asks me why I keep it and it means the world to me. I can't wait to rebuild it now. It is from the early sixties and look forward to having it work like it did 25 years ago! Thanks for making the video.
The Vaseline you used is fine depending on what kind of rubber, neoprene the o rings are made of, the tapered thing with the spring is a pressure relief valve that opens to let fluid out of the pressure cylinder back to the reservoir to relieve excessive pressure if you try to lift something in excess of the Jack's capacity (a safety feature no doubt) Good video all the best to you and yours Sir.
Thank you for the complete break down of rebuilding your floor jack. I definately don't know a lot when it comes to rebuilding these jacks, but I would of been inclined to keep the seals that were made of stainless steel and just replaced the rubber seals and grommets. I believe that is what makes a good ole fashioned jack from the 70's and before compared to one you get at Harbor Freight. I know the steel is thick and the bolts and nuts and everything it is made of is stronger, but that also includes the internals, all but the rubber parts and maybe some springs or even the copper washers that would need to be replaced after 20 or so years. Thanks again for the video and God bless bro.
I have a jack like that that would not hold..So in the meantime I got a harbor freight.. To finish job..It would drop down a little overnite.. Got new seals for the old floor jack rebuilt it and it holds no drop for days and days.. on a super heavy 1979 benz... i love that jack
And this is the way it is done folks. This man knows value. He is not at all afraid to tear into this jack and fix it right back up. American made old jack better than a new China made. I do not trust either one of my floor jacks, both made in China Husky branded. I would trust this Craftsman though. Looked everywhere for one before I bought the Husky Home depot ones. Both, within three years do not want to go back down unless they are pushed down. Thanks for this video. You are what the U.S.A. are all about.
Good job. My Dad bought me the same back in 1974 @ SEARS/ROEBUCK store in No Dartmouth,Mass. Just used it last nite to remove my winter Brighstone tires (Snowtires) Still works like a charm. Thanks A Lot.
Excellent how-to video presentation with attention to the details. I own a vintage craftsman jack to rebuild. Been using it quite a bit these months and noticed that it isn't performing, as it should. This video gives me the confidence to do such a tasking. Thank you, sir!
Me too, I'm going to rebuild my Craftsman now as soon as I find the right kit. That jack worked great for probably 30 years before it started leaking. Built like a brick outhouse. Haven't looked at it for a while now. Hopefully it still has the model/serial number on it.
Great video. Like the way you present it (no nonsense) with just the right amount of explanation without superfluous comments. That jack should last another 50 years before it requires another rebuild. Thanks for sharing.
Good video! Took me back to my "yute." :-) Just did my 1.5 ton green Sears 328.12002 that I bought new in ~1981 for $99, on sale. Great tool that now needed a rebuild. Instructions say to lube it every three months ... now 40 years too late! I have not read all the comments, so may have been covered: After taking the "power unit" out, clean/grease/oil everything else first -- you will be too eager to test the power unit after rebuilding it. My front wheels/axles and the rear wheels' ball and roller bearings were dry as a bone, for example. The trick for putting the handle-spring back in is to 1) remove the handle from the receiver (9/16" bolt), 2) install the receiver with the left bolt, loosely, 3) with the receiver straight up, use your thumb press the spring into the correct position, 4) screw in the (greased) right receiver bolt, 5) tighten both bolts. My plunger's seal was factory-installed "upside down," and the main piston's was "correct," so I put in the replacements those ways too after inspecting the seals' lips' orientations. My kit (Amazon) did include the white plastic washer that was said to be missing in the above video, and I had fewer leftover new parts. My power unit's outer cover/barrel would not budge (seemed press-fitted) so I was not able to replace its o-ring, if it has one.
I just finished watching this video. I have an Astro Jack that I bought off of the Mac Tool man back a few years before your petroleum jelly expired. It's the same exact jack that you have and bought from Sears. Mine was doing the same thing that yours was so I asked our Hydraulic shop about whether it was rebuildable and they said yes it's a copy of a Hein Werner jack (USA made). They told me to pull the jack from the frame and give it to them. They rebuilt it and gave it back to me. It's been working great ever since. Just one thing about the seals you installed. They are dust seals and are designed to keep dust and dirt out of the internals of the jack, not necessarily to keep oil in. That's why they were in stalled backwards. Nice job on the rebuild. Doug
Nice vid. I have the same jack in green. Very used, purchased in 1978. My neighbor also has a green one, but in showroom condition. I'm very jealous. One bit of advice. Don't throw away the rest of the kit. You'll need it if the release valve starts leaking. You skipped repacking it. Also... You should always apply some kind of lube to all o-rings during assembly to avoid tearing. Usually I just take the old seals to a local hydraulic cylinder repair shop to match them up. You'll get exact replacements, and for just a few bucks. Probably under ten. Funny thing is, you actually bled the pump by accident. Pumping the jack with the release valve open, circulates the fluid through the system. The air winds up in the reservoir. It might not have lifted, if you didn't do that first.
Great video! Thanks for taking the time to film, edit and post this. There still are a lot of us tinker’ers out here who love these kind of tasks. I have this exact same jack under the “Matco” tool label. It’s been a go-to piece of my home shop for over 20 years. It started pumping up about a third of the way normally, then the strokes become less and less productive until the pumps are barely a flick of up movement. I thought it was a just low on fluid, but topping off the oil didn’t cure the issue. It holds weight as designed, but takes a lot of mini strokes to get the wheels off the ground of most cars. I dread pulling it apart because I know it’s going to look like a clock made out of rubber seals in there. I’d like to find exactly what valve or area of the jack is causing this defect and only open and repair that area, as the rest of the pump works good. I don’t want to fix something that ain’t broke in another area of operation and cause a new problem that isnt there.
Honestly with this kind of repair, you usually end up find out one problem after another just chasing down "that one valve". Best just to get a kit and swap everything that you can. You already have the thing open and drained anyhow
Thanks for making this. I have what is likely the same exact jack that I got from my dad when he had to move into a nursing home. When I first started working on cars around 1980, it was the jack that we used and I am thrilled to be able to continue to use it probably 45 years after he bought it. It has a slow leak and I was wondering if I could rebuild it, now I know I can. We are closing on a house in about a week and this will be one of my first projects.
Excellent video. As a relocated NYer now living in NC, I enjoyed hearing you explain what you were doing. As for the 24" crescent wrench, here they call that a West Virginia socket set!!
Wipers are used for keeping debris from entering the area. Seals are usually installed with the open end towards the pressure side so they will expand during pressure making a tighter seal. There's always a chance that the previous seal was installed backwards. If you get a leak, flip it over.
Greetings from northern Ireland, got a taskmaster jack that packed up today, chinese but lasted 30plus years, looks very similar, thanks to your video I'm going to have a go at fixing it, thanks!
It looks like you got ahold of my old floor jack!! No joke! I n the Late 70's we used to live in Rome, NY at the old air force base there and I needed a good floor jack badly as I owned and raced a Corvair!! Wife and I bought one at Montgomery Wards on Black River Blvd. there in Rome. I had that thing until I gave it to my neighbor in Germantown, TN back in about 1996. He had it last I knew. I had paid $187.00 for that jack back in probably 1975 and it never failed to hold the load! They were great jacks!! The best thing about them was the large plate that hoisted loads! You could also place a 2x4 block of wood onto that plate and it fit in-between those side edges on the plate.
I have this Jack from my Grandfather, thank you for making this video bro. Thanks to your work Ill be doing the work to save the jack. Plesse keep producing fix videos.
Just got one of those jacks that was my grandfathers....my dad was going to put it out for the scrappers. Its rusty and needs seals. A rebuild is in the works ...Thanks
I'm using a USA made Black Hawk floor jack from the '60s, may need a rebuild, needs fluid again. I love that thing because you don't have to put the handle up all the way to get it to jack, unlike the newer ones. If it is deep under a low car, even a few inches of the handle will raise it up quickly.
I have two 2.5 ton Blackhawk SJ2's. They are from the 70's and look nearly identical to the one you just resealed. Best jacks ever made. I'll be resealing mine soon. Nice video.
You are awesome. I bought a 2.5 ton japanese jack just like yours on my 14th birthday for my first car restoration. I knew someday someone would teach me how to fix it. I am now 50yrs old. I am starting my rebuild on it. Thank you.
Got an old Sears jack I've had since I was a teenager it has the same problem so thanks to your video maybe I can do the same rebuild. Thanks for sharing.
Were you able to get the seal kit for it? I have an old sears jack that is 30 years old. Still OK but I might get seal kit before Sears is extinct. Please advise. THANX
Most major cities have a seal supplier. Google your city. Take the seals to them and they will match what you need. I rebuild a hydraulic cylinder and the complete seal package was $9.
Thank you Sir for making this I need to rebuild my 25 year old floor jack and everything that came up except for yours was bleeding air . Thanks again you are saving me money which is tough these days
To remove the lip-seal from the pump plunger hole, use a thin-blade putty knife. A sharp round corner on the putty knife, and some gentle taps with a hammer, will allow the edge of the putty knife to go between the lip-seal metal rim and the hole wall. Then, pry out with a screwdriver. The lip seal is installed with the lip up. It wipes the push rod to keep it clean. The o-ring seal (and its nylon backing ring), further in the hole, contains the pressure produced by the push (pump) rod.
I have this jack I bought in 1974 at Sears new 328.12001. It is finally hot holding up so I have bought the same kit you did and now I will rebuild it following your video. Much appreciated. I too do not understand why the seals were places upside down in the jack. Very hard to get those in use the OEM way. I guess using a socket inside the seal and driving it until it seats would be the only way. Thankjs
Great informative and helpful video.. thank you for sharing. Friendly suggestion would be to not use petroleum jelly or any hydrocarbon oils or solvents as they are incompatible with may of the elastomer and plastics... Also the petroleum jelly can coat the fine filter screen and make for very slow let downs. Use hydraulic jacking oil to lube up the piston cup and all mornings... Well.Done!
Patrick Guy Yes, I was over here saying no no no don’t, use the oil... I was also concerned about the seal direction but hey he did and a fine job overall and I’m grateful for his video.
Thank you for making this video. I was able to completely rebuild my floor jack. I purchased my Sears floor jack when I was 18. I didn’t want to get ride of it because of the sentimental attachment I have for it. My Dad and I use to work on my 56 Chevy and my 66 Lemans and I have used it for the last 60 years. Thank you.
Very good presentation. Person to Person comments a non-professional may follow & understand. BTW, I purchased that model 40 plus years ago, but haven't used for two years because of same problem. You were my last hope. Thanks again
I've got this jack! It was my dads, I inherited it when he passed. I've been trying to use it but it's not holding. I think this is my next step. I've saved this video! Thanks for the how to!!!!!!!! Much thanks!!!!!
Nice fix! New Harbor Freight Junk Jack vs rebuilding a Better piece of equipment and learning a valuable skill in the process..... REBUILD wins any day of the week.
Thanks Moe!! I paid to have my other jack rebuilt 45 years ago and it's still going strong, so that should be the last time I have to touch this one!!☺
We have 2 of those old jacks that sit in the corner. Say what you will about most of the crap at HF the 2 aluminum jacks we got get used and abused in the shop and keep coming back for more. When your moving the heavy things around all day it gets old real fast.
I have a floor jack like that, way heavy need to have steel toes on when lifting up to my truck incase it drop on my foot. As for Harbor Freight, the Daytona looks pretty good, fast pump and low profile, good ratings and goes head to head against Snap-on jack where they copied the design from.
One of my jacks looks almost exactly like that one, and with the same problem. Gonna order a kit and rebuild mine as well. I used to work at a place called Deer Park Hydraulic on Long Island rebuilding cylinders many yrs ago. I'll never forget the skills I learned in that place.
Safety TIP for jack users, when you lower the jack, tighten the handle so its immediately ready to jack up again, example, you jack up your car, you let it down onto some safety stands, one stand slips out and that part of the car falls some, you are ready to jack fast in case of a problem, been there, done that. DO NOT use your jack only, put something else under the car for safety, even the wheel and tire you may have pulled off. As you can see, it only takes a blown seal to allow the jack to come crashing down. Awesome video, time for me to order my rebuild kit.
I picked up at a govt surplus for 5.00 a similar Strongarm heavy duty 3 tn floor jack about 15 yrs ago it's been sitting in the back corner because I have a hoist. I wanted to keep it around due to it's quality craftsmanship & knew some day/ year !! I was going to fix it. After watching your tutorial, I'm going to put this on my bucket list to fix as well "similar Issue" Thanks for the inspiration !
Hey friend! I stumbled onto this video. I have the same exact jack, different color. Had it 30 years, has not worked the last 15. Have always thought about rebuilding it. I've been tempted by Harbor Freight many times. I'm ordering a kit now. Thanks for this video, I even chuckled a few times. Be safe.
Your video is the most detailed one I've seen about rebuilding hydraulic floor jacks.
I cannot believe it, I finally found someone rebuilding something and talking about what he is doing,
Totally agree, and it's not done at an impressive lightning speed!
Go check out mustie 1 on utube for more rebuilding stuff. He's great
And he wasn't "restoring" it, just a reseal which is all you need, that is if you actually plan on using it.
Thank you for taking the time to make that video. I got an identical jack that recently quit working from my grandfather. The rebuild is going to be easier than I expected with the help of this video.
ХХХ то
Realize the video is four years old, but this majorly helped me to do basic maintenance / repair on a 70's Orange and White jack that looks very similar. Dad has had it since before me; the release valve stopped releasing. Got it apart, cleaned, and back to working with new fluid. Thank you for your detailed descriptions and hard work :)
O thanks nate, mine is doing the same, so I just have to remove and clean it?
@@Dopamine1217 Maybe maybe not. Depends on what failed. I didn't have to pull the hydraulic ram apart, but guys sometimes do. GarageJournal has a really good long thread about how to rebuild Taiwan jacks - I'd start there. In my case, replacing a handful of orings + new fluid got it working again, although it will lose an inch a day or so under load - I never use it without jackstands.
I just rebuilt my 20+ year old Sears 3 ½ ton floor jack. This video helped me understand what I had to do. My main problem was with the big seal at the tip of the shaft for the piston. I didn't mess with all the other smaller o-rings and screws with ball bearings underneath. Thanks for putting this together. Now I have my old heavy jack that I use again. Safety thought: when I first noticed that my jack was no longer working well, I had just lifted up my car to change a wheel. When I went back 5 minutes later to put the new wheel on, I saw that the rotor was very low on the ground. I don't even want to think of having someone (me?) working under the car while this happened.
When I was working after school in a garage (long ago) an old mechanic told me to never trust a hydraulic jack. He said to always use jack stands and pointed to a car across the shop floor which was up on a floor jack and no stands. Amazingly, the jack suddenly lost pressure and the car fell back onto the floor. Thankfully nobody was under it. That stark lesson has remained with me.
Always have a back-up jack stand or log under the frame!
I recommend using a thin coat of the hydraulic jack oil on all o-rings and seals as a assembly lube. Do not contaminate the hyd. system with other products. Thanks
very important,,,,, never reassemble DRY
Absolutely important. I was cringing the whole time.
@@bobg7288 never contaminate it with Vaseline from 1984. Hydraulic fluid ONLY!
Nowadays there's particular "O"ring lube in the market
Contamination is not an issue. Use what ever is handy
one of the best videos I have ever watched you did not tell me about your wife your kids the grass how long you've had the Jack when you bought it none of this other stuff you were right to the point great video. Easy to follow along and mine works perfectly after the rebuild thanks.
Thanks for putting your crescent wrench the proper way to break it. I see so many push against the small, moving jaw.
Nice work. You made it look easy, but there’s a lot of experience in those hands. Nice garage setup, nice tools, and a really nice car!
Thank you Ken!!☺
28 years ago I got a harbor tool and equipment jack just like that and a set of 6 ton stands from my parent's as a Christmas present. As a matter of fact I just got done using it and put it away about 10 minutes ago. Had my Altima up on stands and took the tires and rims to Walmart for a new set of tires.
Best gift I ever received!
She seems a bit slow so I'll be doing this rebuild in the near future.
Thanks for sharing. It took about 3 beers to get through this video BTW.
Finally, a real jack rebuild and not just a Krylon paint job. Thanks. Also, thanks for showing all the newbies what it means to put packing under a workpiece held in a vise.
Great video. I once bought a similar floor jack like yours dirt cheap because it leaked down, the fix was very simple, ran a magnet down into the seat of the check ball, pulled out a tiny metal shaving. Jack worked fine after. Easier and cheaper to try the magnet fix before rebuilding
What do you buy the gaskets at
Great video. I've got an old Sears jack I got from my grandpa's garage after he recently passed. It hasn't worked in about a year, same issue as yours. I've got the rebuild kit coming and am confident I can do it after watching your video. Thank you!
This randomly popped into my feed, and I'm really glad it did, because it never occurred to me how easy it was to rebuild one of these jacks. I've got an old Harbor Freight 3-ton that isn't working anymore, and it may be cheaper to repair than replace, plus I've got an old aluminum Harbor Freight model that doesn't hold or pump up anymore - hopefully I can find a rebuild kit for both of those!
Thanks for the inspiration!
Excellent video. You're right in that the outer seals are wipers to keep contamination from getting inside the pump, so they are installed with the cup facing out. I have the same jack and I'll be rebuilding it this weekend. Thanks for the tutorial.

Thanks for the video. I have my father's 5 ton bottle Jack that is probably 45 years old. The local cylinder shop refused to rebuild it. "It's cheaper to buy a new one" was their answer. Now I can rebuild it myself. Thanks!
This ranchers wife out if Texas enjoyed watching this. I learned something and you're a good teacher!
Thanks alot!!☺
I had a bottle jack , about 20 ton , from the 1930's that my grandfather used on dump trucks rebuilt about 25 years ago . It still works !
A good lesson in parts management and taking note of the number of rotations to remove those valves. Wish I had done that!
Thank you for the great info! I found an old jack on craigslist recently just after watching this video! I am saving so much money and its fun to rebuild it as well! Cool stuff!
Can you tell me where to find the rebuild kit for this jack?
I picked up a 3 1/2 ton Craftsman on the side of the road for free. In real good shape. It jacks up fine for changing tires, but drops in about a half hour.
Going to rebuild it this winter, some cold snowy day. LOL Thanks for the preview of what I'm in for!
Your video made me go out and clean my floor jack-It’s a Sears Model too and identical -I bought it in1983 and has lot of sentimental value-lol!!!...great work and video!!!!!!!!
Our too....1981 I think. Now we have four of them
I
I have a Sears 2 ton floor jack from 1989. Still works but now I have the confidence to rebuild it thanks to your video! Oh...and a large crescent wrench has saved my ass more than once!!
that BLUE PLUNGER WAS ALL THAT WAS NEEDED !! the black one was whooped fyi . thanks for the video iwas very good I have a bunch od Lincoln and Walker jacks from the 70's and have rebuilt them and this is the type of info our kids need. you know our 30 and 40 year old kids. Thanks again.
I love that. Yes there are 30 & 40 year old kids who could learn a thinga 2.
Joe Shabidu Keep rockin', Every repair is a confidence builder, and you're never done. Recent additions to building skills- trigger spring on a top-break revolver, patch plastic ends of radiator with epoxy. The stuff was broke anyway, I dont think much more harm could be done, if the fix didn't work. Best wishes!
I have an old Blue Walker with the yellow one piece handle from the 70's I had rebuilt in a jack shop. Just sent the pump in.
The beauty of the internet is in my opinion, someone somewhere in the world will have an answer for something. Who knows what could be solved in any field, thank you everyone who takes time to post their version of things
Thanks Mate!!☺
This actually helped me get my jack working again, somehow.
Mine is completely different but just watching someone take it apart helped give me an idea.
I realized I had opened something I shouldn't have and a part fell out.
I took another look and sure enough I found a tiny piston lodged in a crack in the jack.
Used the magnet trick with an awl to get the piston and spring in the correct position.
Jack is now working good as new.
The oil was low which was I took it apart in the first place but I opened the wrong part and the manual doesn't actually tell you what to do.
The manual even labels every part except the holes... go figure.
I bought this same jack in 1972 and ordered the seal kit. This is great to see what to expect before I disassemble it.
Excellent video. My old floor jack leaks down all the the time so as a consequence it has sat in the corner of my shed for 15 years. I'm going to go to a bearing shop and see if I can get the seals to rebuild it. Looking forward to this project and thanks very much!
GREAT VIDEO !! Your easy method of step by step is great to follow, your trouble shooting possible issues is spot on, camera work was acceptable and your explanation of parts excellent.
Ordered this style of jack from Sears Roebuck Co in 1970 and shipped to Germany where we were stationed. Had a little VW bug I used as my work car. I could jack the car up, pull the little 31 HP motor out, carry it inside our government quarters into the kitchen, drain the oil out into a pan ( for PROPER disposal ), wash the oil screen out with gasoline outside, put the motor back into the car, affix the throttle cable and generator cable, pull out the jack stands, let the car down, refill the oil, start it up, pack the wife in the passenger seat and head to the Commissary on base for a grocery run all in 45 minutes.
I got my money's worth out of this jack, every penny. The jack is setting in my shop today under the work bench and THANKS to this vid I'm going to rebuild it next week for sure. That little jack was made like a German tank and heavy like one too. Jacks like that are well worth the rebuild kit cost to repair. I'll have to look on the jack to see where it was made. Don't know if Sears bought Japan or China made then but I might be surprised.
Thanks for a GREAT instructional video. You rank way up the list for a professional quality job here.
Thanks alot Bud!!☺
Nice job on the rebuild. I have been in the automobile repair business for over 45 years and still use my floor jacks. Never had to rebuild them but was always curious on what was inside of one. I found this video extremely interesting. Nice catch on that pressure regulator. I might guess that's the safety valve to keep from overlifting the jack and damaging it. But the process seemed pretty simple that you did here. I also liked your style of systematically rebuilding each section and also I liked the fact that you put that paper towel down in that cavity to keep trash out. You're truly a professional.
Thanks again for taking your time to make this video. Nice job!!
Thanks alot, we appreciate your comment!!☺
Great video. Auto body tip. When using hammer hold index finger pointed up onto the handle towards the head of the hammer. Gives much better control of your grip and aim while striking. Give it a try.
Excellent work and fantastic video
I have a "Big Lots" Chinese jack from 1980, $29.95, WAY before Harbor Freight, with the same leaking oil problem. You have inspired me to try a repair later on...thanks! I'm rebuilding power window motor gears now, all learned on TH-cam.
Great job ..
I use to rebuild these jacks back if the 70s & 80s, and let me say they were good jacks .
The crap coming out of China , well you know .
Hine Warner was a good Jack, Sears actually sold this jack in different lifting capacity with the SEARS logo .
Also Lincoln was a vere reliable floor jack, same as the Walker well back in the 50s .
This junk thats available today is use it and throw it away when it falls ....
The old school of rebuilding things are a thing of the past anymore....
Thank you for posting this video, brought back many memories...
Thanks Bud!!☺
Great work man. I Cut my teeth on floor jacks just like that. Back in the 70's too. Brings back memories!
Nice work I have my Grandads jack that I used to work with him in the shop when I was a Kid. I have had it since he passed away and it needs rebuilding. My wife always asks me why I keep it and it means the world to me. I can't wait to rebuild it now. It is from the early sixties and look forward to having it work like it did 25 years ago! Thanks for making the video.
Citadel Tactical blunder
Thank you this just gave me the inspiration to dig out a couple of old jacks that quit working. Good job.
Thanks Bud!!☺
The Vaseline you used is fine depending on what kind of rubber, neoprene the o rings are made of, the tapered thing with the spring is a pressure relief valve that opens to let fluid out of the pressure cylinder back to the reservoir to relieve excessive pressure if you try to lift something in excess of the Jack's capacity (a safety feature no doubt)
Good video all the best to you and yours Sir.
I have it for 50 years , been rebuilt. 2 years , now it's as good as new , & 80% still has original color
You’d make an awesome Instructor for sure,thank you for the detailed breakdown it’s very helpful.
You remind me of my ol' metal shop teacher from 40 years ago! Gr8 instruction & Thanx 4 the attention to detail boss, much appreciated!
Thank you for the complete break down of rebuilding your floor jack. I definately don't know a lot when it comes to rebuilding these jacks, but I would of been inclined to keep the seals that were made of stainless steel and just replaced the rubber seals and grommets. I believe that is what makes a good ole fashioned jack from the 70's and before compared to one you get at Harbor Freight. I know the steel is thick and the bolts and nuts and everything it is made of is stronger, but that also includes the internals, all but the rubber parts and maybe some springs or even the copper washers that would need to be replaced after 20 or so years.
Thanks again for the video and God bless bro.
You really can’t beat the quality of these old floor jacks 👍🏻👍🏻👍🏻
Indeed
Yeah Buddy!! ☺
Very good job explaining and not wasting time talking uselessly.Thank you so much
I love this video! Thank you so much for making it. You included everything needed to know with clear instructions, audio and editing. So good!
Thanks Bud!!☺
I have a jack like that that would not hold..So in the meantime I got a harbor freight.. To finish job..It would drop down a little overnite.. Got new seals for the old floor jack rebuilt it and it holds no drop for days and days.. on a super heavy 1979 benz... i love that jack
I was going to throw away my craftsman hydraulic jack away , but after watching this video I'm rebuilding my jack .
Me too. I have several laying around the shop I can now rebuild.
Were you ever able to find the correct seal kit?
@@agtronicLazzars
And this is the way it is done folks. This man knows value. He is not at all afraid to tear into this jack and fix it right back up. American made old jack better than a new China made. I do not trust either one of my floor jacks, both made in China Husky branded. I would trust this Craftsman though. Looked everywhere for one before I bought the Husky Home depot ones. Both, within three years do not want to go back down unless they are pushed down. Thanks for this video. You are what the U.S.A. are all about.
The screw, spring and pintle are an over pressure relief valve. Thanks for the video. Good job👍
Ken, Do you know what the approx. setting is on that pressure relief screw? Thankyou Sir
@@GRAYSTAW 8 full turns on mine, which was about one turn past where the spring started to engage.
Good job. My Dad bought me the same back in 1974 @ SEARS/ROEBUCK store in No Dartmouth,Mass. Just used it last nite to remove my winter Brighstone tires (Snowtires) Still works like a charm. Thanks A Lot.
Excellent how-to video presentation with attention to the details. I own a vintage craftsman jack to rebuild. Been using it quite a bit these months and noticed that it isn't performing, as it should. This video gives me the confidence to do such a tasking. Thank you, sir!
Me too, I'm going to rebuild my Craftsman now as soon as I find the right kit. That jack worked great for probably 30 years before it started leaking. Built like a brick outhouse. Haven't looked at it for a while now. Hopefully it still has the model/serial number on it.
Great video. Like the way you present it (no nonsense) with just the right amount of explanation without superfluous comments. That jack should last another 50 years before it requires another rebuild. Thanks for sharing.
Thanks alot Bud!!☺
Got the same jack from the 70's also! Great job.
Good video! Took me back to my "yute." :-)
Just did my 1.5 ton green Sears 328.12002 that I bought new in ~1981 for $99, on sale. Great tool that now needed a rebuild. Instructions say to lube it every three months ... now 40 years too late!
I have not read all the comments, so may have been covered:
After taking the "power unit" out, clean/grease/oil everything else first -- you will be too eager to test the power unit after rebuilding it. My front wheels/axles and the rear wheels' ball and roller bearings were dry as a bone, for example.
The trick for putting the handle-spring back in is to 1) remove the handle from the receiver (9/16" bolt), 2) install the receiver with the left bolt, loosely, 3) with the receiver straight up, use your thumb press the spring into the correct position, 4) screw in the (greased) right receiver bolt, 5) tighten both bolts.
My plunger's seal was factory-installed "upside down," and the main piston's was "correct," so I put in the replacements those ways too after inspecting the seals' lips' orientations. My kit (Amazon) did include the white plastic washer that was said to be missing in the above video, and I had fewer leftover new parts. My power unit's outer cover/barrel would not budge (seemed press-fitted) so I was not able to replace its o-ring, if it has one.
bought same one in ny lasted for decades sars 99.00
I just finished watching this video. I have an Astro Jack that I bought off of the Mac Tool man back a few years before your petroleum jelly expired. It's the same exact jack that you have and bought from Sears.
Mine was doing the same thing that yours was so I asked our Hydraulic shop about whether it was rebuildable and they said yes it's a copy of a Hein Werner jack (USA made). They told me to pull the jack from the frame and give it to them. They rebuilt it and gave it back to me. It's been working great ever since.
Just one thing about the seals you installed. They are dust seals and are designed to keep dust and dirt out of the internals of the jack, not necessarily to keep oil in. That's why they were in stalled backwards. Nice job on the rebuild. Doug
Nice vid. I have the same jack in green. Very used, purchased in 1978. My neighbor also has a green one, but in showroom condition. I'm very jealous. One bit of advice. Don't throw away the rest of the kit. You'll need it if the release valve starts leaking. You skipped repacking it. Also... You should always apply some kind of lube to all o-rings during assembly to avoid tearing. Usually I just take the old seals to a local hydraulic cylinder repair shop to match them up. You'll get exact replacements, and for just a few bucks. Probably under ten. Funny thing is, you actually bled the pump by accident. Pumping the jack with the release valve open, circulates the fluid through the system. The air winds up in the reservoir. It might not have lifted, if you didn't do that first.
Great video! Thanks for taking the time to film, edit and post this. There still are a lot of us tinker’ers out here who love these kind of tasks.
I have this exact same jack under the “Matco” tool label. It’s been a go-to piece of my home shop for over 20 years. It started pumping up about a third of the way normally, then the strokes become less and less productive until the pumps are barely a flick of up movement. I thought it was a just low on fluid, but topping off the oil didn’t cure the issue. It holds weight as designed, but takes a lot of mini strokes to get the wheels off the ground of most cars.
I dread pulling it apart because I know it’s going to look like a clock made out of rubber seals in there. I’d like to find exactly what valve or area of the jack is causing this defect and only open and repair that area, as the rest of the pump works good. I don’t want to fix something that ain’t broke in another area of operation and cause a new problem that isnt there.
What patients!!!!
Honestly with this kind of repair, you usually end up find out one problem after another just chasing down "that one valve". Best just to get a kit and swap everything that you can. You already have the thing open and drained anyhow
JohnnyP414 is right, like it or not. The first thing people need to learn is that they have a lot to learn,
Thanks for making this. I have what is likely the same exact jack that I got from my dad when he had to move into a nursing home. When I first started working on cars around 1980, it was the jack that we used and I am thrilled to be able to continue to use it probably 45 years after he bought it. It has a slow leak and I was wondering if I could rebuild it, now I know I can. We are closing on a house in about a week and this will be one of my first projects.
Remember, your never to OLD to learn something, Thanks,i can see all those old jacks coming back to life , mine too.. Thanks
Add to it the fact that it keeps you busy and out of the fridge...
@@bvnseven LOL!
Wwwby.
Excellent video. As a relocated NYer now living in NC, I enjoyed hearing you explain what you were doing. As for the 24" crescent wrench, here they call that a West Virginia socket set!!
Wipers are used for keeping debris from entering the area. Seals are usually installed with the open end towards the pressure side so they will expand during pressure making a tighter seal. There's always a chance that the previous seal was installed backwards. If you get a leak, flip it over.
Greetings from northern Ireland, got a taskmaster jack that packed up today, chinese but lasted 30plus years, looks very similar, thanks to your video I'm going to have a go at fixing it, thanks!
Using my favorite hammer!! I've used this body hammer for years as a precision adjuster for seals, etc. Works perfectly!! Nice job!!
It looks like you got ahold of my old floor jack!! No joke! I n the Late 70's we used to live in Rome, NY at the old air force base there and I needed a good floor jack badly as I owned and raced a Corvair!! Wife and I bought one at Montgomery Wards on Black River Blvd. there in Rome. I had that thing until I gave it to my neighbor in Germantown, TN back in about 1996. He had it last I knew. I had paid $187.00 for that jack back in probably 1975 and it never failed to hold the load! They were great jacks!! The best thing about them was the large plate that hoisted loads! You could also place a 2x4 block of wood onto that plate and it fit in-between those side edges on the plate.
Great video! I have a Sears jack about the same age that I'm getting ready to rebuild. Thanks for taking the time to make this video.
Thanks Bud!!☺
I have this Jack from my Grandfather, thank you for making this video bro. Thanks to your work Ill be doing the work to save the jack. Plesse keep producing fix videos.
Thank you for taking the time to put this together. I'm sure so many of us will benefit from your work and positive attitude. God bless!
Thanks Bud!!☺
Just got one of those jacks that was my grandfathers....my dad was going to put it out for the scrappers. Its rusty and needs seals. A rebuild is in the works ...Thanks
Thanks for this video. Just finished rebuilding my Sears jack. Works like new.
I have 3 of these floor jacks and all need rebuilding. Thank you this video was well done and will be a big help.
I have the same jack and it's time for the same service. Thanks for sharing !
I'm using a USA made Black Hawk floor jack from the '60s, may need a rebuild, needs fluid again. I love that thing because you don't have to put the handle up all the way to get it to jack, unlike the newer ones. If it is deep under a low car, even a few inches of the handle will raise it up quickly.
Good to know! I have vintage 3ton all cast 1945 Blackhawk floor jack that I'm going to restore, its a beauty!
Blackhawk floor jacks are King. I still have several from my 'Dad's Body shop from the 50's
That looks exactly like my Dayton floor jack.....wonderful jack ! Thanks for the video !
Good work, I see them every week dropped off at scrap yard! I have 3 now and they are way better than any other jacks I have used!
I have two 2.5 ton Blackhawk SJ2's. They are from the 70's and look nearly identical to the one you just resealed. Best jacks ever made. I'll be resealing mine soon. Nice video.
Thanks Bud!!☺
Great vid thanks for tapeing the process, i have a sears my dad had for years i thought i would fix and now i can.
You are awesome. I bought a 2.5 ton japanese jack just like yours on my 14th birthday for my first car restoration. I knew someday someone would teach me how to fix it. I am now 50yrs old. I am starting my rebuild on it. Thank you.
Got an old Sears jack I've had since I was a teenager it has the same problem so thanks to your video maybe I can do the same rebuild. Thanks for sharing.
Were you able to get the seal kit for it? I have an old sears jack that is 30 years old. Still OK but I might get seal kit before Sears is extinct. Please advise.
THANX
Most major cities have a seal supplier. Google your city. Take the seals to them and they will match what you need. I rebuild a hydraulic cylinder and the complete seal package was $9.
@@shoeleh07 Good idea. THANX. Uncle Google to the rescue.
Nice job! Thanks for taking the time to film & edit all of that. I'm doing the same jack tonight.
You have inspired me to rebuild my old jack, it died on me a few years ago. Thanks for the video, enjoy all the engines as well.
Thank you Sir for making this I need to rebuild my 25 year old floor jack and everything that came up except for yours was bleeding air . Thanks again you are saving me money which is tough these days
Well, I finally found a use for my dads old 24” adjustable wrench. Great video👍
No no him look by my noi by hi it
thanks for share your experience and skills!!!
To remove the lip-seal from the pump plunger hole, use a thin-blade putty knife. A sharp round corner on the putty knife, and some gentle taps with a hammer, will allow the edge of the putty knife to go between the lip-seal metal rim and the hole wall. Then, pry out with a screwdriver.
The lip seal is installed with the lip up. It wipes the push rod to keep it clean. The o-ring seal (and its nylon backing ring), further in the hole, contains the pressure produced by the push (pump) rod.
I have this jack I bought in 1974 at Sears new 328.12001. It is finally hot holding up so I have bought the same kit you did and now I will rebuild it following your video. Much appreciated. I too do not understand why the seals were places upside down in the jack. Very hard to get those in use the OEM way. I guess using a socket inside the seal and driving it until it seats would be the only way. Thankjs
Great informative and helpful video.. thank you for sharing.
Friendly suggestion would be to not use petroleum jelly or any hydrocarbon oils or solvents as they are incompatible with may of the elastomer and plastics... Also the petroleum jelly can coat the fine filter screen and make for very slow let downs. Use hydraulic jacking oil to lube up the piston cup and all mornings...
Well.Done!
Patrick Guy Yes, I was over here saying no no no don’t, use the oil...
I was also concerned about the seal direction but hey he did and a fine job overall and I’m grateful for his video.
Thanks!
Thank you Bob!! I hope it helped you!!☺
Thank you for making this video. I was able to completely rebuild my floor jack. I purchased my Sears floor jack when I was 18. I didn’t want to get ride of it because of the sentimental attachment I have for it. My Dad and I use to work on my 56 Chevy and my 66 Lemans and I have used it for the last 60 years. Thank you.
Very good presentation. Person to Person comments a non-professional may follow & understand. BTW, I purchased that model 40 plus years ago, but haven't used for two years because of same problem. You were my last hope. Thanks again
Great job , glad you were able to save it . Great quality jack .
I've got this jack! It was my dads, I inherited it when he passed. I've been trying to use it but it's not holding. I think this is my next step. I've saved this video! Thanks for the how to!!!!!!!! Much thanks!!!!!
Nice fix! New Harbor Freight Junk Jack vs rebuilding a Better piece of equipment and learning a valuable skill in the process..... REBUILD wins any day of the week.
Thanks Moe!! I paid to have my other jack rebuilt 45 years ago and it's still going strong, so that should be the last time I have to touch this one!!☺
We have 2 of those old jacks that sit in the corner. Say what you will about most of the crap at HF the 2 aluminum jacks we got get used and abused in the shop and keep coming back for more. When your moving the heavy things around all day it gets old real fast.
I have a floor jack like that, way heavy need to have steel toes on when lifting up to my truck incase it drop on my foot. As for Harbor Freight, the Daytona looks pretty good, fast pump and low profile, good ratings and goes head to head against Snap-on jack where they copied the design from.
One of my jacks looks almost exactly like that one, and with the same problem. Gonna order a kit and rebuild mine as well. I used to work at a place called Deer Park Hydraulic on Long Island rebuilding cylinders many yrs ago. I'll never forget the skills I learned in that place.
805ROADKING wear you buy the part
Safety TIP for jack users, when you lower the jack, tighten the handle so its immediately ready to jack up again, example, you jack up your car, you let it down onto some safety stands, one stand slips out and that part of the car falls some, you are ready to jack fast in case of a problem, been there, done that. DO NOT use your jack only, put something else under the car for safety, even the wheel and tire you may have pulled off. As you can see, it only takes a blown seal to allow the jack to come crashing down. Awesome video, time for me to order my rebuild kit.
Another bleeding method is to jack it up and keep pumping the handle. That pumps the fluid through getting the air out.
I picked up at a govt surplus for 5.00 a similar Strongarm heavy duty 3 tn floor jack about 15 yrs ago it's been sitting in the back corner because I have a hoist. I wanted to keep it around due to it's quality craftsmanship & knew some day/ year !! I was going to fix it. After watching your tutorial, I'm going to put this on my bucket list to fix as well "similar Issue" Thanks for the inspiration !
Thanks, I always wanted to know what the innards looked like!!!
Thanks. I been given a jack that leaks will now give it a go when I have got the replacement O rings etc.
Awesome work!!! I love the vintage tools! I would have went with scraping the old paint and give it a new coat lol
Hey friend! I stumbled onto this video. I have the same exact jack, different color. Had it 30 years, has not worked the last 15. Have always thought about rebuilding it. I've been tempted by Harbor Freight many times. I'm ordering a kit now. Thanks for this video, I even chuckled a few times. Be safe.
Thanks Bud!! Good Luck!!☺
