perfect video, no mindless talk, only explicit visual explanation, and I'm going to give my bottle jack a try at restoring it. Bought an 8 ton for 8$. It has no oil and I have nothing to lose, but some time. Thank you for taking the time to explain the process so clearly.
Note to self and others : When in storage, never lay these jacks on their side - they leak! My brand new jack leaked into the sparewheel well over the course of a few months. Thanks to you I managed to save it by a top up bleed. Thank you!!!
Tip: you can replace hydraulic oil using mineral or synthetic 15w40 ! They have the same specifications and are less aggressive on the seals. I'm an engineer in hydraulics and we often replace hydraulic oil with 15w40 because it is less harmful to nature.
well -- depending on how much one is used - hydro oil has much more antishear and antifoaming agents - and would flow much easier it is said - and why would not a good 30 weight oil be as good if using oil - - a small pump does not need a flow rate additive - nor does it need a more expensive oil - if lazy people would change the oil more often - they could use anything - diesel fuel will even work - if it had additives - it could last forever - just a thought - they were selling replacement oil at harbor freight for a dollar - now Im sure it is 2 dollars -- ahahahahaha - i have a lot of old jacks - 50 tons even - did not know hydro oil was worse than the others for nature - must be some of the additives - cause oil is oil - and most studies on syns have not had enough studies - only that they last longer so they are better - we use less over time - oil company's are the only ones really doing the studies - and they are of course all LIARS -- ahahahaha --- paying trillions to cover up their facts and mistakes - even plastics - beings they are made from petroleum are said to cause cancer - hemp is said to be the best oil on the market - and with additives - they too can last years even --- the oil company's have paid tons to keep it off the market - even though it causes no harm to the environment --- but anyway -- ahahahahaha
@@user-du7pe6pm7d foaming is not an issue as hydraulic tanks are pressurized before feeding the hydraulic pumps, antishear also isn't an issue especially with synthetic oil because hydraulic pumps use butterfly valves to generate pressure and they are made from brass, hydraulic cylinders use seals they never touch metal to metal. We actually found that replacing hydraulic oil with 15w40 was much softer on the insides of the hydraulic hoses, they often started to peel from the inside as the hydraulic oil was eating them away. Nonetheless we switched to Castrol biobar duo environmental rules in many countries (I do maintenance for marine excavators the BA1100 in particular but also a liebherr 995 and the liebherr 994 is now replaced with an Hitachi)
Just done this to my motorcycle lift jack. The piston rod had rusted and rust had got in and polluted the oil. I thought the seal might be gone, but once cleaned and refilled with new hydraulic oil it was fine. Wish I'd watched your video first!
Repaired a manual hydraulic ram that operates the reverse of this (pumping pulls the ram in) but everything was nearly identical to this jack. Honestly amazed at how similar all the components of the pump were to this. I followed along with what you did here and everything worked a treat. Great video!
Thanks for the video, I have an old big hydraulic jack, that my dad bought numerous years before I was born and I just turned 59 a couple of weeks ago and it needs to be fixed . So after watching you rebuild this one, I am going to try to fix my old jack, just mainly because it was my dad's and it being that old . I have 4 more newer jacks, one of them is only about 4 years old and the other 3 are about 20 years old . 🤗👍💫
I really appreciate the closeness of the camera. I can actually see what your doing. Thank-you. I also appreciate you getting right on subject, meaning I didn't have to listen to a long speech about safety glasses, shoes, gloves, etc.(I know all that stuff)
Nice vid. Got to be honest though, it looked like it was just low on oil. Maybe it would have kept leaking over time but who knows. Interesting to see how they come apart.
Had one of the best oldest hydraulic bottle jacks probably there ever was & I can't begin to count the number big Tractor tired & truck tires it lifted After I know 35 yrs probably it started leaking around the seal very little paint was left on it & at the time I just wanted to go buy a new one for my Dad & we turned nthe old one into a door stop After a half dozen uses of the new bottle jack I regretted ever buying it but Computers were just getting started & I didn't know about researching for parts then .
Interesting. Our late 60's vintage Sears Craftsman 1.5T floor jack (Made in Japan) has a thick rubber bushing near the base of the main shaft. It got destroyed years ago when my dad loaned the floor jack to a neighbor who tried to lift one side of his Kenworth tractor trailer. About ten years ago I managed to find a seller in Belmont Shores , CA who sold repair kits for various types of hydraulic jacks. I guess the moral of my story is, if you treasure your tools and equipment, don't loan them out because people won't respect them and destroy them, or they will and try to keep them.
It's been about ten years since I ordered the kit from him. I remember his business was at his home in Belmont Shores, CA. I remember his location because it took about ten working days to get the parts to me, just 12 miles away.
EXCELLENT. I love the idea of using a loose bench vice for the large nut on top. I definitely will add that little trick to my "mental tool-box" !!! Very good demonstration ! When you went back and bled the filler hole of air, THAT'S what I haven't done! I subbed. Bill, from Tn. 🇺🇸
A great instructional video. The only thing you didn't do is find the original handle with the proper tip to open and close the jack valve and check to see if the extension on the top of the jack was stuck since it was acidentally left in the back of the pickup in a rain storm for about 2 weeks. Great job.
I have a small collection of the older Jack's from the 70,s. You can't beat the old Walker Jack's and also an old sears jack all made in USA. I personally do not trust the made in China Jack's for they are poorly made. So don't discard Grandpa's old jack lol. Thank you for sharing this video 👍
Oh this video is primed n in depth way way over my capabilities. Your very good but I'd have to pass n pay for a new one. Time is very limited in my week.
Sorry to hear that, yes this is a rather time consuming process. In that case buying a new one is the better option, they are really cheap to buy new most of the time.
@@AJRestoration yeah buddy 😎 . some of the people would say Chuck the one that is broken and buy a new one . You on other hand take a broken one of those and fix it saving the money 💵 to use for other stuff
Did you change the seal on the main piston?. It looked a little flat to me. If a replacement isnt readily available maybe a little tread tape on the inside channel would give it more bulk and reduce oil blow-by.
If a hydraulic jack will work without without oil in it will more than likely work with oil in it. 99.9% of people would have just filled it with oil and gotten it to operate and been fine with a little seepage here and there. If I find a hydraulic Jack like this that will still operate I usually drain all the oil out and replace it with ATF and about a tbl spoon of Sea Foam and Marvel Mystery Oil. Usually any leaks that exist go away shortly after several uses. It was interesting to see how it comes apart but I couldn't imagine you could find the seals for even if it needed them.
To fill it correctly, the jack should be standing upright, and fill oil up until it trickles out of the fill hole. After pumping it right the way up then releasing it all the way down, vent the air from the fill plug with the jack in the upright position, then top up to fill hole again. The way you filled it could be over or underfilled. Since you had the jack laying downhill when you showed venting the air, any air bubbles would've still been stuck at the bottom end of the jack with no way to get up to the fill plug🤣
@@johnwilliams8918 Sure, that's a possibility, but highly unlikely. Even then manufacturer knowing a certain volume is unlikley, they would fill them to the plug hole, pump to bleed air and top up, then box it up ready for sale.
But it worked didn't it? I find it amazing how many pro level technicians watch these videos! Without them who would tell everyone that they were doing it all wrong... Even if it works fine after the repair... There is always an unsung hero, to extend an olive branch, and tell whomever they can, how it was done all wrong, and that if they would have done it like YOU... IT would be better... Except YOU, never made a video about it... Instead you just criticize the one you seen? Wouldn't it be funny if YOU made a video and some " gentleman critiqued everything you tried to share? Wouldn't that be something?
@@kiphenricksen6029 Or, perhaps leaving a comment on the correct procedure isn't to critique the video maker at all, but instead they might actually learn something they weren't aware of? The comment from someone experienced may also simply be shared to inform the inexperienced person that watched the video how to do it the correct way, and might actually help them avoid unknowingly trusting the shown procedure in a video that may contain misinformation, or a slightly questionable method that may result in a less than ideal outcome. You're welcome to watch as many of my videos as you like, and please critique as many as you can (since I have actually made videos myself too, but as yet I don't remember being critiqued by 'some gentlemen' as you mentioned) I would treat any critique as constructive and perhaps benefit from it.

That's the nature of Americans. We criticize each other to death and leave no stone unturned. It's hard but that's why Americans have always had the best. That's how great leaders are made, they have to wade through all of that incessant bombardment on their way to the top. I think that's changing though.
I see where the O rings came from but there were two special seals, one at the bottom of the body cylinder and one on the piston. Were they replaced? Where did you get them?
good work! maybe you can build a suitable attachment on the handle. then you don't always need extra pliers to loosen it. I did the same with my jack :)
The Rebuild part seems straightforward, its obtaining the seals and "O" rings that I can see are the most difficult. Getting a rebuild kit for a 'offshore" hydraulic jack is almost impossible!
A lot of coulda shoulda comments...thanks for the video...those of you who gave advice...let us all know when you offer a helpful video, although we may be waiting a long time.
yu would never want to use water on mechanical moving parts from inside - yu could use vinegar - it cleans rust very well -- but would have to clean it off well with gas anyway - water is kryptonite to metal - especially if it moves -
@@user-du7pe6pm7d good morning,this is simple machine ,I've used pressure washer ,with hot water then air pressure it ,to remove leftover water drops,then used lubricated it with WD-40 spray or hydraulic fluid also
@@tandemwings4733 - huh - after many dozen times with different thinks - I have found gas to clean the best - with a part cleaning brush if applicable - then diesel to oil - but to each their own ! - water is not good for metal - nor can air get all water out before rust starts - it would take many many minutes to blow all the water out to the point of not a good thing -
My hydraulic jack has same problem like this one: It moves very bad and uneven. But I already replaced the seals, cleaned valves, changed oil. What exactly leads to a bad movement ? Air inside ?
@@AJRestoration I directly went into my workshop. Pumping with the value open. Then opened plug on the tank. I heard air coming out. Tried again: Works fine! Thank you!
I watched you disassemble this jack and replace the "O" rings along the way. And it seemed to fix the problem. However, do you actually know which "O" ring caused the problem? I ask because I got a floor jack that won't pump up and I can't find any repair kit of "O" rings for it since it is so old. I've already totally refurbished the entire jack and powder coated the parts that are used for the lifting operation. But the jack itself was only rattle can painted as to not melt the "O" rings inside when curing the power coat paint. . So I have to measure and find the individual rings to try and fix it. Just wondering if you knew which ring was the actual culprit...
Sometimes fitting a O'Ring that fits tight but is the wrong size will work, as long as it seals and does not pinch. In my case it was the lack of oil and the presence of air in the system.
In a pinch, yes you can use motor oil. However using hydraulic oil is advised as it has anti foaming properties that is much safer to use. Do not crawl under any car or heavy equipment if you don't have a failsafe in place like a Jack Stand Trestle rated for the correct weight.
ahahahahaha -- get your money ready - they will tell yu about replacing all the old worn out parts that dont work anymore -- ahahahahaha - just buy new ones for close to the same money on line -- ahahahaha

You're right! Stupid, annoying music has ruined many videos.I don't understand why people think that they just have to put music on a video.
Me too these type of videos with just the sounds of the process are the most captivating, btw do you have to strip it down this far to repair it?

Thanks for watching!
Well worth the time spent watching this video I’ve got a couple under the work bench that I’m gonna have a look at this weekend thanks buddy
Well done, it was as if I was watching myself rebuild it; I have never done it and have one waiting out in the shop. Thank you.
Never thought of the up side down vise trick , that’s what I call “ thinking out of the box “ .
finally a real repair that was comprehensive without the BS. thank you!!
if you go to a hard ware store make sure you buy the correct o rings they make metric and standard and don't over fill the oil great video
Thanks for leaving that beauty it's dignity. And not sandblasting it glossy or replacing the sign.
Nice vid.
Got to be honest though, it looked like it was just low on oil.
Maybe it would have kept leaking over time but who knows.
Interesting to see how they come apart.
The main seal was leaking a little, a quick fix would be to add oil, but I wanted to see what it looks like inside haha
Where.iwillget, jack, spare
The real tricky part is rebuilding the Jack handle.😄
Well now I know what the inside of a jack looks like I won't have to take it apart, I'll just add oil if it leaks a little. =)
Great pictorial but these things are so cheap nowadays it’s not worth the time to do this.

yu would never want to use water on mechanical moving parts from inside - yu could use vinegar - it cleans rust very well -- but would have to clean it off well with gas anyway - water is kryptonite to metal - especially if it moves -
@@user-du7pe6pm7d good morning,this is simple machine ,I've used pressure washer ,with hot water then air pressure it ,to remove leftover water drops,then used lubricated it with WD-40 spray or hydraulic fluid also
@@tandemwings4733 - huh - after many dozen times with different thinks - I have found gas to clean the best - with a part cleaning brush if applicable - then diesel to oil - but to each their own ! - water is not good for metal - nor can air get all water out before rust starts - it would take many many minutes to blow all the water out to the point of not a good thing -
Wow great job 👏👏
Thank you! 😊
When you got the spares to do the work it can b done
I like your vice grips! 😳🤣👍👍
Hahahaha they work a charm!
GREAT VIDEO, I HAVE LEARNT ALOT
Glad it was helpful!
It must suck to not have a solvent tank i cant remember back that far lol 😆
Would it be possible to do a video on a floor with rollers? Sure would appreciate it very much.
Thanks Buddy! You're the best !
Tester needed to set load settings 1.5 ton etc on right side screw.😊
Nice restoration
Thank you!
My hydraulic jack has same problem like this one: It moves very bad and uneven. But I already replaced the seals, cleaned valves, changed oil. What exactly leads to a bad movement ? Air inside ?
It could be air in the system, it could also be a one-way valve the's not doing its job. They are small ballbearings that have to seal properly.
@@AJRestoration thank you. I will check it again!
@@AJRestoration I directly went into my workshop. Pumping with the value open. Then opened plug on the tank. I heard air coming out. Tried again: Works fine! Thank you!
Very nicely done.
I watched you disassemble this jack and replace the "O" rings along the way. And it seemed to fix the problem. However, do you actually know which "O" ring caused the problem? I ask because I got a floor jack that won't pump up and I can't find any repair kit of "O" rings for it since it is so old. I've already totally refurbished the entire jack and powder coated the parts that are used for the lifting operation. But the jack itself was only rattle can painted as to not melt the "O" rings inside when curing the power coat paint. . So I have to measure and find the individual rings to try and fix it. Just wondering if you knew which ring was the actual culprit...
Sometimes fitting a O'Ring that fits tight but is the wrong size will work, as long as it seals and does not pinch. In my case it was the lack of oil and the presence of air in the system.
Check with Lazzars for parts and seals.
I've got my bottle jack in the vise but I cannot seem to crack open the top. any tips or tricks for that?
Just don't use heat, in this case leverage is your friend. I used a vice to grip it and used a pipe in between the jaws for leverage.
Nice. Then it falls while under the truck. Time for a new jack.
Can we use hydraulic oil or engine oil?
In a pinch, yes you can use motor oil. However using hydraulic oil is advised as it has anti foaming properties that is much safer to use. Do not crawl under any car or heavy equipment if you don't have a failsafe in place like a Jack Stand Trestle rated for the correct weight.
Very nice and straight forward tutor,
I have two of those mobi jacks. Was thinking of sending them to mobi jack to get them repaired
ahahahahaha -- get your money ready - they will tell yu about replacing all the old worn out parts that dont work anymore -- ahahahahaha - just buy new ones for close to the same money on line -- ahahahaha
Este video merece mas de un LIKE.
Did you just clean it or did you replace all the o-rings in gaskets
