Hydraulic Jack O-ring repair, Oil Fill & how to Bleed! Easy 

man you killed the cylinder shaft with those vise crips.

Someone gave me the same Jack from this video thinking it was no longer working because it was losing all the oil, thanks to your advice I fixed it, I just needed to change the O-ring, now it works perfectly as if it were new

Straight to the point and no F'in around. My kinda dude. Very informative, thanks.

THAT WAS AWESOME!👏 I COULDN'T FOR THE LIFE OF ME FIGURE OUT WHAT WAS GOING ON WITH MY JACK!🤷🏻‍♂️ I ADDED OIL, TIGHTEN THE BLEEDER, ECT!😤 IT WAS THE O-RING UNDER THE HANDLE JUST LIKE YOU SHOWED US!🤦🏻‍♂️ SO THANK YOU!🤘

Thank you so much man. I got this same jack that I only used once 3yrs ago and went over to my sister's house a few days ago to replace her flat tire with her spare only to discover it wouldn't budge or lift anything. Turns out the oil leaked out completely and here I thought I had to shell out $100+ for another one. I also couldn't figure out how to get the oil plug out and yours is the only video I found that showed that. Thanks again!

Best jack repair video. The pace, the presentation. That was excellent!😊

Great! I have a similar old trolley jack (2 ton MVP from Northern Tool ) that had stopped lifting. I was just going to toss it and go buy a new one until I saw this video. You just saved me about $40 bucks. Thanks!

Thanks for this! I need a video that goes into detail since I have not ever done this and have 2 jacks that need this entire process done. One is pretty old, so we shall see if I can get it working again! Appreciate you!!

Thanks for the tips. I have no leak. Bleeding fixed my problem.

You can also unscrew that bung instead of marring that piston with vice grips. The whole thing comes out and you can tap it out gently. I think it's like 17mm

This is an excellent video! You are a natural teacher. 🙂🙂🙂

Sir I act upon your advice. And I fixed my jack. Thank you very much for helping me through your video. God bless you.

you cannot use a Vice Grip Plier on the Pump plunger....! You are damaging its Smooth wall and the Pumping capacity will be reduced. The Scarring on the plunger will finally damage the Oil Seal too.

Thank you! Nicely explained.

Well earned thumbs up from me. Your instructions worked like a charm. Now my hydraulic floor jack is working just like before. Thank you, sir!

You saved my jack headed for dumpster. I was able to fix my floor jack for .47 cents. Where the plunger or small piston goes in mine had a small ball bearing at the base.

Cool! Good instructions! I subscribed after watching it. Appreciate the help man....Thumbs up!

Very useful, thank you!

Very good informative video, thanks for posting.

Excellent video. Thanks a lot.

If u have lost lots of oil, you want to top it up and bleed it too. Loads of good videos show how to do it. I'd personally put the vice grips around a rag to not damage the poston.

Thank you!! This video helped tremendously!!

Helped me solve my problem with my jack,thanks.

Good teacher; clear, concise...

thanks bro. very helpful video

Finally a jack repair video that isnt actually a video telling you how to put oil in it. Thank you Sir.

Great information! Im a subscriber now! Thanks sir!

I learn allot. Thanks

Video muito bom. Parabéns 👏👏

Nice video, thank you

Thanks man 🙂 👋 Thanks to You, I have fixed my jack! 👋

Very helpful!

Thank you very much for this video…I just fixed a jack that was sold to me from offer up and wasn’t told it was broken.

Thank you so much i saw this video and help my husband fix the jack it work

Thanks for the vid and here is something you or no one will believe. I just disassembled by craftsman 2 1/2 ton floor Jack that has always been leaking a little. Yet lately it’s been losing lifting power and leaking more. I bought it new about 20 years ago and used it a lot. It has NO O ring! Amazing it even worked at all. I’m guessing someone in China left it out by accident and quality control was non-existent. I’ve got a few older never used O rings so hopefully 1 will work. Even if it’s a little dry rotted it should do a LOT better. LOL. I will try and post an image or link.

Got the same one Preciate it!

Awesome! You helped me so much. Boosted my confidence and now I’m going to find people who think their jacks are busted and repair and sell. Hahaha.

Nice guide. Thanks for the vid, man 👍

Thanks, nice video

replaced a #7 o-ring on my 30 year old transmission jack. damn! now it works great, saved me $500. awesome. Thanks!

Jack says: thanks mate for sharing your experience

NOICE! HIGH FIVE FROM NYC

Thank you very much brother, God bless

Thank you very much!!

Thank you very much sir,very helpful as I have 3 of these type Jack's and they've all decided to either not work at all or just barely lift a couple of inches. P.S. you might be wise to put a rag or something between the vise grips and the lift piston. Thanks again

You are genius my buddy I like your explanation I am an Indian guy and my name is Abid Bandi may almighty bless you and your family

Thanks!

Man I took this back to AutoZone I had paid $80 for it, on sale. They said 1 warranty was out. I knew 100% it was like only 8 months. No arguing with those fools, no help. Your vid got my jack back in order. Maybe these harbor freight seals will work better than the ones that janky duralast used. Thanks for saving me at least a Benni I only ended up paying pennies

Very useful. Thank you for sharing!

This answered my question about what o ring to get. Autozone still sells that same "Needa" assortment. 👍

This video helped me out a lot, thank you!

Recently refilled my Jack and realized the o-ring was leaking. This videos covers it all 👏

Ima try to fix mine tomorrow doing the same thing, I’m going to see if I can remove the bleeder plug to relieve that pin pressure before pulling it out, if i can’t then I’ll leave the head on the pin then try to pry it up and out, awesome video bro I hope i can fix mine

Thanks a lot for the video! Very useful for me!

Thanks

good job desmond in ireland

Thanks 🙏 very much for sharing this video with process of how to fix the hydraulic jack. I have done replaced the o ring but it still doesn’t work. Is there some other reason why it doesn’t work sir? Thanks 🙏 again for sharing the video sir.

Excellent Video, very well explained!!!!

I have that same jack & mine says drain the air by flexing that ruber oil filer plug to the side😐 gud viDO thO, I didNt know that's where you filled thE oil, thNQ🖐️

Best jack video ever. Clear, concise, no nonsense video w 100% attention on the viewer! Thank you Bro ! ! !

THANK YOU, T about 5:40 thats what i am trying to find, i "winged how to fill it, put too much in, and that POPED and hit me in the head lol. Then had to rinse my eyes. Lol i am ok. *time to find WALDO that cheeky ninja dude.

This is excellent... Thank you so much...

Excellent sir. I have a question. Can the jack get in air if the rubber plug has a pin hole?

Good video however you should never use vise grips on smooth hydraulic pistons that are smooth for a reason. They mate against other o-ring seals and scaring them will essentially ruin them.

when you popped the pin out that has the o-ring on it....why didn't you loosen the bushing nut on the bottom and just remove that? I'm just curious....never done this before

helpfull

👍

What is the flathead screw next to the pumper next to for? My jack has the same screw.

Usually, I'll have to go through a couple of tutorials to find the correct instructions. Not this time. Thank you for making the time to help others!! 🙏

Hi brother I thank you for your show about how to repair the hydraulic jack. I have one and its leaking and I go round to look for O~ring but I can find one. I am living in Italy please help me to get O-ring set no problem for money for the bill of postage fees thanks. I hope to hear from you Shalom. Thanks

If anybody needs O-rings for the piston and the release valve, HMU and I'll send them to you in a regular envelope. You can pay me a trivial amount if you want. I don't care. I got a 50 pack of each from Grainger so I know I'll never use even one tenth of them. I'll send you as many as you want.

I undone the two screws and one ball bearing and one spring fell out. Not sure which hole the spring and bearing comes out off. Fyi I'm referring to the twist to release the jack screw and the screw with the do not remove cap on. (Not talking about the rubber filler bit). I was trying to get as much old fluid out as possible. I think the bearing goes on the twist to release screw as the screw has a simple on the button of it, and I thought the spring went under the do not remove screw but again who knows, all I know is that it's not working at all now.

Thank You, that's my Jack repaired and good for a while longer. Principle much the same to repair my Engine Hoist?

Big ups to you bwoy

My Pro lift model # G-2593 3 ton jack raises up fine, but won't hold a load. Do you think it needs a total main cylinder rebuild, or just one of the easier to replace o rings? I already tried adding oil and bleeding it. It does seem to leak fluid out of somewhere, but not on top. Please advise.

Hey dude how did you get the cap and clip claw back on mine came out and i can't put the simple part back 😂

A little stop leak might help too.

Thank you for this video Sir; you are legend.

Hi! How many steel spheres ( valves) does that jack have? I think I lose some! Do you know its dimensions ? Thanks!

Thank you so much!

I just had a go at replacing my o rings on the piston and pressure release screw. They are no longer leaking but my jack still doing the exact same thing only goes up a few pumps then stops. I think the hydraulic as gone.

you need to replace the o ring of the valve too.

How the heck do you get that plug back in? Mine is being a pain in the neck

hey bro, my jack doesnt even lift a bit, with pressure, and by pressure i mean even the spring at the side, and if i remove the spring it works properly, what is the issue, can you guide me. on how to fix it.

Thanks just save my some cash👍👍👍

I have the same jack, but the value is leaking fluid ?? What should I do ?

and if someone messed up that dont touch screw on jack how is/ if is fixable? many thanks in advance

There's another "screw' at the right side of that piston you are taking off. What is that for?

I changed the same o-ring that you did and i even bled ths jack, the arm that lifts doesnt even move when i pump it.....oil is toped up, the valve is closed and it doesnt even move....what could be wrong with the jack?

Enjoyed the video, but please don't put vice grips on the piston -

How bout when the pump handle gets stuck down & won’t pump back up?

How you put of plug back sr .. ?

I have the same jack but release button is broken how to fix ? Is anyone know how to fix it thank you 🙏 much

Can anyone tell me what the diameter of the O-ring is?

Can you use brake fluid as jack oil?

where did you get that o ring kit?

how to tell what viscosity oil it needs

dude sound like kev mac

Hello guys. I have a small Chinese 2 ton floor jack that serve me well the last 5 years. The problem (I think i have) is that it doesn't stay up. What I mean.. with no load I lift it and the next day Is down. It drops about 1-2cm every 20 minutes. I change the oil and do the bleeding procedure already. Also when I turn anticlockwise the pressure valve to lower the jack,the silicone filler cap pop up. I press the side of it with a flat screwdriver and always push air out,no matter how many times I do bleed it before. I pull oylut some oil and now the filler plug stays in strong but again when I press it air goes out. There is no leak outside. Is that normal or I should do something else?

can i put motorcycle fork oil?
