How to repair a floor jack that leaks fluid (1 year anniversary updated edition)

To celebrate my one year on KZbin, I thought it would be wise to redo my first video (which I think is terrible). In this video, I show the correct way to fix, fill, and bleed a jack that is leaking fluid out of the o-ring on the piston. And a big THANK YOU to everyone who has watched my videos, supported me, and welcomed me to the KZbin family.
jack in video is Craftsman 875.501152

I must say how much I appreciate your floor jack repair video. Mine looks almost identical, only in red, manufactured by Rodac (NL) FYI: for those in Europe looking for the size of the o-ring: it's a 16mm x 4 mm (inner diameter x thickness)

[@WJHandyDad]

glad it was helpful. Mine still works although I did replace the o ring a second time since the original filming in 2016

[@jamesturnure9735]

This is a great follow-up video and thank you for the guidance! I picked up a similar jack for nearly nothing off Marketplace for my son and wanted to replace the pump O-ring seal before giving it to him. If I might, I'd like to offer a couple of additional tips that I found helpful regarding removal and replacement of the O-ring. - Pump up the jack before you begin...at least half way. That will avoid the flood of oil when you remove the plunger. - Once the plunger is removed, pull out enough hydraulic oil from the pump cavity to clearly see the O-ring and plastic retainer. - Polish the plunger shaft on a wire wheel and then with steel wool to a shine. Also, polish the lead-in chamfer on the plunger...this is rough machined and could abrade the O-ring upon insertion. - Grab a 1/4" wood dowel and round the end. Instead of using a screwdriver which may cut or nick the new O-ring, maneuver the new O-ring into the groove below the plastic spacer using the rounded end. - Before reinstalling the plunger, open the jack and push down on the jack pad. This will push some oil out of the plunger port and purge any remaining contaminants in the plunger area.

[@WJHandyDad]

great tips. thank you for sharing

[@Count_Smackula]

Thanks! I need to fix my 2.5 ton Craftsman jack I bought back in '77.

[@BobbyDigital28]

Thanks brother will see if I can stop my 3 ton jack oil spills with your tips.

[@WJHandyDad]

hope it helps... mine is still working great although I did replace that o-ring a second time since the original video

[@VR6_SKC]

Very good vid mate, i had the wrong size o ring from halfords but it still fit eventually and once oiled was smooth, my jack was full of water and was completely buggered

[@tellfile]

My jack would not hold pressure very long. The book said bleed it by having jack arm released all the way down, then open the filler plug and put your foot on front wheels, then pull the jacking arm all the way up by hand. While up, put filler plug back in, lower jack arm with the handle release then jack up something. It fixed mine ... no more slowly dropping down.. Didn't have to pump anything looking for air bubbles and stuff.

[@YoungHeartedSoul]

good update. i see you edited put where you remove the piston pump and throw on the floor. that would of course scratch the shaft of the pump and in turn damage the new o ring. cool vid.

[@Mercmad]

Most popular because there are lots of leaky jacks out there . :-)

[@nighttrain022]

Exactly

[@ezzzzrrrs7646]

Great vid helped for the job got the same jack thanks guy😊😊😊😊

[@raymondjiii]

I have a smaller condition of what you had with the leaking piston. Where about's might I find the o-ring or even a set of o-rings if I wanted to match it up with what I have - which are two Allied 3.5 ton jacks. Thanks for making these floor jack videos! It motivated me to get both of mine working better.

[@WJHandyDad]

I searched and searched looking for o-rings that fit. The only place I could find them was Amazon.

[@Derpy1969]

Thank you. I have this exact same jack, but mine is a 3.5 ton and is black and gold. I bough the full rebuild kit from HRC for under $40 because mine leaks internally.

[@WJHandyDad]

hopefully you get yours fixed back like new! Good luck!

[@timb7775]

This is exactly where my jack is leaking from. It's a very old craftsman 3 ton that was in the basement when I moved in so decided to clean and paint it and it looks and works great. Used it many many times and now just developed the leak. It's a strong jack, no reason to get rid of it if I can fix it easy enough.

[@WJHandyDad]

should be fixable. It's 7 years since I filmed the fix and I am still using it. I did replace the o-ring one more time since the original video

[@timmyb1874]

@@WJHandyDad I saw the o-ring package says Buna 90, is that 90A hardness? Im coming across both 90A and 70A type o-rings. Think it matters? the 70A I can find locally, they sell #94 which is 5/8-7/8-1/8 also.

[@JamieUnpluggedcom]

GREAT INFO! j

[@JoseMartinez-ig7vd]

Thank you bro

[@SeanA88]

I'm gonna try this. I just scored 2 free jacks off Craigslist but they need a little work. One is a 3 ton though

[@tipsclubs01]

I have two 3 ton Floor Jacks, one was a Freebee, because they said it didn't work, but it didn't have the lifting Plate that fits in the hole in the top, where it meets the car frame. But got the jack lifting by filling the 3 access holes for the fluid. 2 screw out holes, and the rubber plug in the cylinder. So now I had find a similar jack with a lift Plate to fit this one. Found one on Offer Up, that they said it wouldn't lift, cost me $25, Plate fit perfectly. Then I filled and bleed the other jack, and got it working too. Took the 2 big front wheels off cleaned them up, oiled them, then went to the 2 little wheels on the back. WARNING: A nut and lock washer holds them on the Frame, and I thought it had captivated bearings, it didn't, it had a top and bottom bearing plates with 19 little ball bearings in between, and I had to chase all these little ball bearing across the floor. So be careful if you remove the 2 little back wheels. I cleaned the plates, put grease in the groves or both plates and placed the ball bearings in them and held them together till I put the wheels back on the jack frame. Great Video, saved them both for future use. Thank You.

[@WJHandyDad]

thanks for sharing those tips

[@plusblood5101]

Awesome

[@gregalexander527]

Great Video ! Can you tell me how to adjust the DO NOT ADJUST screw with the Orange DO NOT ADJUST cap over it. I adjusted mine before I saw your video. Thanks !! Greg

[@WJHandyDad]

I do not know. I don't mess with that do not adjust screw.

[@te2751]

SAME HERE BUT I HAVNT STARTED VIDEOING BUT I AM DAMN GLAD I DIDNT GET RID OF MY JACK I THINK MINE IS A 1970'S

[@MrSamBowers]

At 2:21 of your video. To the right of your big spring. Do you see a hump on that tank? That's your fill plug.

[@robertthomason7924]

Any videos on repairing the release valve assembly? I have replaced the release spur and helical gears. I have taken it apart and it turns, plenty hydraulic fluid, but as soon as it is tightened it stops turning. (SEARS/CRAFTSMAN 3-ton floor jack)

[@WJHandyDad]

sorry I don't

[@notajp]

The plastic ring is called a backer ring. It should be installed on top of the O-ring.

[@zoranmarinkovic2843]

I have the same jack. Purchased in 1995.

[@WJHandyDad]

that's probably the year I bought mine too!

[@yourmom-pi6jq]

I have this same exact jack leaking in that same exact spot. Where can that oring be found at and or what size or part number is it?

[@WJHandyDad]

it's in the video description too: amzn.to/2iUhZHt

[@gerardlunow567]

I have the same one and probably bought it early 90's. I am going to completely rebuild/paint it. Is there a kit number to replace all the seals? Thank you.

[@WJHandyDad]

I'm not aware of any

[@goaskalic]

I just bought the seal from amazon Part# B0188VX5A4 Was about 4 1/2 bucks. Good luck, i'm trying to gat the seal in now, not very easy

[@BrianGallop-oz7qf]

Do you fill that tank were you replacement o rings

[@WJHandyDad]

initially I did put some in there, but the proper refill procedure is through the rubber cap

[@EngineerPrepper]

Mine looks very very similar amx leaking at the same spot... mine is a GJ 6000 3 ton. i too cant find replacement parts... im going to bite the bullet on your suggestion of the o ring 208. crossing fingers

[@WJHandyDad]

good luck - I hope it works. Remember to put some jack oil on the o-ring before installing (I don't think I mentioned that in the video)

[@Darjan_Spasojevic]

Hey, on that plunger pin does the flat spot go downward?

[@WJHandyDad]

I'm sorry but I'm not understanding the question and I filmed this video summer 2016 so it's been a few years

[@kay19833]

How do you know what oring size to order? do they have numbers on them?I mean it's not jacks are cars where you can order spareparts by just searching under the make. How do you go about this?

[@WJHandyDad]

I measured it with a ruler

[@D4x4Bronc]

my 05 Craftsman has a double lip upper dust seal and below that is a groove for the o-ring and a plastic washer under it. And unfortunately the new o-ring does not want to fit in the groove with the plastic washer. I may try removing the plastic washer.

[@WJHandyDad]

hope you get it - it can be tricky. I heard someone else mention putting the o-ring on the piston and then trying to install it by pushing the piston it.

[@bradanesi3998]

I've got this same jack - first repaired it about 4 years ago using this video as a guide. Now it's leaking again but the nylon O-ring (the second one in the groove) appears to be bent and buggered up so much that it won't allow the new rubber O-ring to slip into place. Wondering if maybe just the rubber O-ring can suffice?

[@WJHandyDad]

my guess is the plastic ring is needed and hopefully you can find a suitable replacement

[@RonGJX]

Looks like your floor jack is identical to mine. I removed the oil plug and added oil, and then purged the air, but I could not get that original oil plug back into it's hole no matter what I did. Wondering whether you had a similar problem, and if so how did you finally get that plug back in.

[@WJHandyDad]

I honestly don't remember having any trouble with it. Try putting a dab of jack oil on the bottom of it or soaking it in 303 and see if that helps.

[@RonGJX]

@@WJHandyDad Could be that my rubber plug is very old and very hard, and therefore not pliable enough to squeeze back into the oil fill hole. Will order a new plug that hopefully will fit. Thanks for your response.

[@macster1457]

is the jack handle supposed to be able to turn all the way to the left (counter clockwise) until it stops? - I notice if I do that, I can't pump the handle unless I turn it to the right a few times... is that normal?

[@WJHandyDad]

mine pumps no matter where I have the handle turned. Whether or not that is normal or not, I don't know

[@starchaser2489]

Was your pump piston 3/4" in size, that's what I have.

[@MrRichard57000]

Mine is 19mm....

[@MrRichard57000]

BTW that's close to 3/4 inch...... Can you give me the thickness from the o ring?

[@user-gh5if5oo2f]

How do you service the wheels?

[@WJHandyDad]

I've never serviced them on this jack, I did on a Harbor Freight jack here: kzbin.info/www/bejne/jafRc62eeK5lfpI

[@sethvaughn6316]

My inherited Craftsman has been leaking from the same spot. Would you say the o-ring is a ¾" outer diameter x ⁹/¹⁶" inner diameter x ³/³²"?

[@WJHandyDad]

I put a link in the video to the o ring that fit mine. No guarantees yours is the same. I had to special order mine because I bought several sets of o rings and none of them were correct. I found my size by taking the old o ring and holding it over a ruler

[@sethvaughn6316]

@@WJHandyDad Well. Mine ended up using 2 different sizes and by dumb luck, I bought them! Can't do a test until I see how to bleed it, but that can wait for tomorrow. Plus I forgot to get more fluid. 😋

[@WJHandyDad]

@@sethvaughn6316 glad you were able to get it fixed. The fill and bleed should go smoothly. I've replaced my o-ring 1 time since I filmed this video and the jack still works like brand new

hi there we have same one and need repair can you tell us the repair kit code or Jack trademark please thanks

there wasn't a specific "repair kit" available for mine, I had to measure the o-ring and order replacement o-rings off Amazon

[@BadWeatherfreak]

Can I buy these at homedepot?

[@WJHandyDad]

I found them on Amazon. That was the only place I found them at and I looked at quite a few places.

[@Revnge7Fold]

I would say the real test would be to test the jack under load. My jack also does not leak when not under load and pumps properly. But as soos as you push it to 500kg-1ton it stats to leak at that o ring again :(

[@WJHandyDad]

I replaced the o-ring one time since I filmed the original video, but that jack still works great. I show it picking up my Avalanche in the final bleed video

[@Mistabushi]

I just bought a new Halfords floor jack(3T) and used it maybe once and notice out of sudden it started leaking like mad right from the piston…..

[@WJHandyDad]

that sucks, hopefully they'll exchange for a new one or give you a full refund
