- I show you how to fix a hydraulic trolley jack that won't go up. This is a junkyard find that just needed some hydraulic fluid amzn.to/3KHlRdC and a good clean.
More information can be found at notsealed.com/...
Always use hydraulic fluid or transmission fluid in your jack, nothing else.
Don't throw away your Hydraulic car jacks fix them.

I never knew this was a thing. I bought a jack from a car boot sale that worked under no load but when I got it home I couldn't get the car up. Had some transmission oil laying around so a perfect fix. Thank so much
Your welcome glad you got it working 😁
I have a jack very similar got it from halfords here in the UK must be 40 ish years ago still goes great quite well made
Same here, Halfords Trolley Jack over 40 years ago, Silver in colour still going strong .......👍
Simply explained!! Best video out here that I can understand fully so far. Thanks man!
Your welcome, Glad it helped!
I have this exact jack in silver, and it's been giving me issues. I've had other trolley jacks, but they don't lift quite as high as this one. I'm going to have a go at this. Thank you!
Often if jacks dont lift high enough they just need a top up with and and bleed all the air out. Good luck
I've owned a jack just like it for about 40 years or more and it's still good. I might have to put some oil in it from time to time but it still works.
So many jacks thrown out because of this problem found 1 like this put oil in wala it worked thanks
Hydronic fluid is not "oil".
I just fixed a nearly identical jack I bought more than 25 years ago. Have been storing it inside so the outside condition was good, but it didn't want to lift anymore. Your video saved the day! It was almost empty despite no visible leaks. Now it lifted a 2 ton car without hesitation. I had already bought a new one, but this oldie has both thicker steel and larger piston than the new one, so it doesn't flex at all and requires fewer strokes to raise, despite being rather cheap back in the day. Thanks a alot for the video!
Your welcome glad I could help. Yes the new generic hydraulic car jacks are not built like they were many years ago.
You are a life saver. I have an old trolley Jack which l discarded(but fortunately didn't throw away) because it was not lifting. I was actually planning to buy a new one. Thanks to you l refilled it with ATF
Glad its back in action 😁
I have the same jack and I was fixing it… I did not bleed it until I watched this… thanks man
Glad you could fix your hydraulic jack. Once you know how to bleed them most jacks are easy to fix.
I do go on ,so I will . Earlier post was just today. Before all that I watched maybe 6 other posts about filling and bleeding and never even came across any that told me how much fluid to put in. Did exactly what you recommended and instead of the ATF I had fork oil from some bike fork rebuilds I had done recently. I' m going to be wondering how that bumper got in there for years to come . Thanks again.
Yes it is important to not over fill or under fill these hydraulic jacks.
It should work for another 20 years.
you may have saved my jack, lemme try it, i hope you can do a vlog how to repair excessive leaking of the oil
Excessive leaking of oil is often due to worn seals or a pitted rusty piston shaft. It would require a total tear down to replace the seals.
after closer inspection i see the leak coming from the hydraulic cylinder itself and not the piston. i managed to remove it but quickly realised i need a bench vice which i dont have and it costs as much as the jack, so instead of fixing it im just getting a 3 ton jack to replace the 2 ton@@NotSealed
I bought a similar jack 18 yrs ago new in the states.duralast .gave me a hard time even getting half way up here lately and I'd had enough . Fix it or toss it later. Pulled the ram out and got the o - ring out of the cylinder. Hadn't tore it up thankfully. Put in a different o ring . No help . Ok . Put 1st back
in. Refused to go. Better light and wa la there it is ! A plastic round bumper had found it's way into the groove in the cylinder where the o ring sits. The simplest effing things sometimes. Ta Ta ! Thanks.
Glad you fixed it. Thanks for the update hopefully it helps someone else in the future.
Thanks man, helped me sort out my no name china jack.
BTW I checked and it seems that ATF is not hazardous.
Super find, man.
Thanks man. Helped so much.
Note to self. Just because a jack will pump up, does not mean it will hold a load of heavy weight.
Not holding weight is a sign of an oil leak. Load test it first after repair.
Any jack can fail at any time that’s why you use jack stands as soon as your vehicle is high enough from the ground. This trolley jack is in use probably a few minutes that’s all.
It’s disgusting how unreliable modern jacks are !
What do you say?
@@vertihvost7675 anyone who goes under a car without Jack stands and only supported by the trolley jack is an idiot
Exactly..
Thanks for the upload new rings and fluid in mine it's as good as new 😊
Thank you very much for showing this. It helped a lot. 👍👏💪
Glad I could help.
I just watched this video as I am changing the oil on mine, which looks exactly the same as yours, but yours looks in better condition 😅
Preciate the video just fix my jack in 5 min and no money out of pocket thanks
Excellent glad it helped. Saving money is the name of the game in this environment lately.
Perfect ... Well Done 👍
Thank You
Glad I could help.
After watching this I found some "power steering fluid" in the garage. Are you sure we're ok to use this as alternative? I don't want to damage my jack (very similar looking model to this). I can wait and order some hydraulic oil if that would be better for it. Thanks.
It will work fine and won't cause any damage.
@@NotSealed Thanks for the confirmation, Will have another go at the weekend 👍
PROTIP about old rusty steel-wheeled trolly-jacks: Re-OIL the 4 wheels, and 2 casters while you are restoring it.
#Winning !
Great idea thanks
Where'd you get the syringe with tube? Does that come with transmission fluid?
Some auto transmission fluid bottles do come with a tube otherwise your local chemist will have what you need.
Thanks sir for your demonstration of how to fix the roller jack. I did the same way as you did, but the oil is showing it’s full and some oil even flows out. So I did not get to put oil into it. What should I do to get it to work again sir?
Must have an air lock. Watch the video again and follow all the steps to purge. Just don't put oil in it.
just what I was looking for thanks a lot!
You're welcome glad the video helped you out
Someone else commented and it was my thoughts as well that being tossed due to no oil and non-pump would make me leary of the seals and therefor have little trust raising anything heavy.
Oil does not just evaporate. It may leak out and usually leave a stained trail.
However, an jnstance could be a storage issue which may have placed yhe jack at an odd angle which allowed oil to seep out of the fill plug.
If I deemed it a keeper I would need to do a leak down test with a heavy object and a tape measure.
Just my thoughts.
I have had one instance if a seal blowout while raising a racecar and had a specialty brake disc crack upon impact. That sucked. This is rare and hard or slightly leaking seals would normally be a slow let down. (Pardon the pun)
Yes doing a load test is a must on any old jack. I always place some metal axle stands under the car when I am working just in case a hydraulic jack let's go.
Safety first.
What're ya doin raising or lowering a trolley jack with wheels removed and without jack stands?
Dont blame Jack. Unless thats your name? Then yeah blame Jack. Stop blowing ya seals mate
I would try a gain thank u
Hey, I followed what you did but it still does not work. It won't pump because someone sabotaged my jack. I pumped over 30 times after I filled with transmission fluid & more than 30 times after I tighten it up. What else can I do?
What sort of sabotage?
Having major issues with engine hoist. Tips on bleeding this?
I'm guessing the engine hoist has the hydraulic pump mounted vertically. It will be the same procedure to bleed as this video. Just look for the oil fill plug and the bleed screw.
Hi.i did exactly what u did.changed the fluid with atf,changed the leaking orings,bled the system..now my jack wont lift at all.any ideas?
Very strange I can only think that there is still an air lock, the oil level is not correct or that the piston is not sealed properly.
Also make sure that the hydraulic ram lower screw is tightened up.
Finally fixed it after 3days of tinkering 🤣 i remembered i drained the fluid by removing the 2 screws including the screw that we were not suppose to touch.placed the jack upside down and up to drain. I didnt notice that the small ball bearings,spring and small metal part also fell to the drain bucket.til i came along this photo at google that it has this small parta inside the screw holes 😅 luckily i havent drained the bucket so i was able to fish the small parts using magnet 😂 anyway,thanks for the reply. Cheers!
Good job thanks for the update. These jacks are simple devices and it's always a simple reason they don't work.
I have the same jack and it leaks from the release valve. I took it out and there is no o'ring like other jacks so how do you fix this?
Could be a few reasons. Bleed the jack again properly. It could also be overfilled with oil.
You could always add an o-ring.
@@NotSealed Thanks. I used a sharp hooked tool to pull out a very stuck ribbed rubber sleeve. I replaced with 3 o-rings, topped up 20ml of oil, bled air and it is now fixed. You are a legend. Thank you for your video and prompt reply.
I’ve done all the steps but it’s still not lifting. Doesn’t seem to be leaking anywhere. Any other ideas what I could try??
Must have a blown oring, air lock, or still low on oil.
I did this i bleed the jack but when i pump it up it is still dropping can u give me some help
You must have leak somewhere or an airlock. Have you added more hydraulic oil?
how come american company never made this pump jackfloor...
i have one orange pump jackfloor and put 2 handles on the both side...
much help alot
Dude, use better grammar when claiming to be American and communicating with an English man.
He may think we are all illiterate.
Um that is ... unless you're Yoda.
LOL
@@ThePeopleVerse No kidding!
I didn't understand that at all!🤨
Glad I wasn't the only one lol.
Sometimes the sealings are the issue.
Yes if an oil seal is blown out or worn it will need to be replaced.
But you did not show it actually lifting any weight. Just the weight of itself.
mine dont even lift, added fluid and bleeded it still having problem
Piston seals must have failed. Sometimes its just cheaper and simple to buy a new one amzn.to/3z9Lhtb
If it was low on fluid, there has to be a leak!
Possibly it's a junk yard find so far it's working great no leaks. Held up to a 400kg load test.
The leaks are slow leaks man just put oil in, Jack your car up and put Jack stands under it in your fine
Spray it clean with brake cleaner.
A really cheap looking jack usually sold at DIY stores and Supermarkets hardly worth fixing
Why throw something away when all it needs is some hydraulic oil.
My rubber plug ripped
You tell us not to put oil in it, but then you keep calling the hydrolic fluid "oil".
You will be amazed at how many people put engine oil in their hydraulic jacks. This is wrong and you must use hydraulic fluid or hydraulic oil. Both terminology are correct as some manufacturers call their products differently. Guess it depends on what part of the world you come from.
Good information
Thanks.
A couple of drops of brake fluid will soften the seals
I have heard about this old method to restore old seals. Never tried it myself, thanks for the tip.
All that low oil had to go somewhere . It doesn't evaporate .
Yes overtime small oil leaks onto the floor. Everytime you use the jack a small amount of oil lubricates the ram.
Air also can enter the system over time with worn seals.
