How to fix a leaking floor jack

11/09/2013 NOT ONE DROP LEAKED OUT
wow
11/15/14 not one drop still. not leaking or one problem with it over a year!!!

[@paulcrews9146]

Best video I looked at. there were several. Thank you!

[@daverdino]

Thanks for the video! I have the same Jack starting to leak. Awesome!

[@AbellTo]

I have the same issue with my floor jack, I found your video review very helpful. I will take a look and see if it's repairable. Thank you.

[@chuaongpacpo9801]

Mine is exactly the same this floor jack, but mine lost model & serial numbers so any one please give me one Thanks

[@bobb1271]

Didn't have to pull off the top,but the small o ring at the pump did the trick to stop it from leaking...thanxs

[@bobwoerner8731]

hi.i have a 6x10 cargo trail. not sure of weight but reg says 2990 gvwr. the height is aprox 861/2 " but my garage opening is only 84".due to hoa rules i need to keep it in my garage.i was able to get it in yrs ago by flattening the tire and it just barely made it in.this makes it impractical to use often.i'm thinking of keeping it on bare rims just to pull it in and out of garage with no clearance headaches .once in the drive way jacking it up installing the rimed tires and going.and doing the reverse to get it back in the garage.do you think it safe ,leaving the hitch connected to the truck ,to jack the trailer up from the center rear with a 3 ton floor jack and 2 jack stands lifting both wheels off the ground simultaneously to remove the rims and install the rims with tires on them to avoid having to jack one side at a time to make this operation faster?

[@MooneyMarineLLC]

Hey, thank you for the informational video. I was wondering what size impact socket did your buddy use to remove the nut/cap on the bottle jack? Was it a 2-1/8 as you mentioned early on in your video?

Hi bam 6972, Where did you buy rebuild kit for the bump (not a small seal)? Mine is the same of yours but 3.5 tons Thank you

[@ronnysmith2949]

What's the model number on the jack. I have the same one and need a rebuild

[@Rusiputki]

I have the same jack I borrowed from a neighbor for good 5 years now, he doesn't use it on his boat, and I admit it's good engineering but recently it only pumps when you pump all the way down. I want to go back to the old cheap designed once as they great and easy to repair. You can buy 3-4 for the price of the one in that video. In fact I already found couple that have been thrown away. I just replaced the oil and they worked.

[@bam6972]

yup its only the seals that keep the oil in. usually .. sometimes its the actual piston seals inside and that's more of an expensive repair. and usually is not worth it. but if its leaking externally then this video will fix most jacks

[@mobileautorepairbypacheco1806]

did you know what part #is it to order on line the repair kit

[@bam6972]

i got the seals from my local hardware store called arones hardware and another where I actually got them from was called Fastenal. only 30 cents for the oring. and its still not leaking one drop. just checked it today... just take it apart and take the oring to your hardware store and match one up. that's what it did.... GOOD LUCK

[@chuaongpacpo9801]

Hi bam 6972, Where did you buy rebuild kit for the bump (not a small seal)? Mine is the same of yours but 3.5 tons Thank you

[@fujiobass]

Thank you for the video, I wonder where do we find the replacement O rings for the jack ?

[@bam6972]

+fujiobass local hardware or auto shop. got mine from fastenal

[@andyf2813]

Thanks for the video. Quick question. I have a small craftsman jack and it lifts up the car with no problem. The thing is when its all the way up holding the car it goes down little by little after a span of 10 minutes. Can this be the seals too??? I believe it is a 2 1/4 or 2 1/2 ton jack. Thanks

[@bam6972]

no its not those seals. its the plastic rings around the shaft that hold the pressure back. there either worn really bad or there is scoring in the cylinder. more than likely its junk. most of the time the cylinder is scored to the point where a new set of rings or plunger or whatever they call those plastic things is not going to seal properly and will leak again in time. you can try to take it apart and if the cylinder is in good shape then a new set of the plastic rings is all you need. but finding parts for an old jack might be troublesome.

[@rosamoscosa6723]

Hey bro good info thank u.. my craftsman 3 ton floor jack seems like is leaking from same place as yours should I change the 2 o rings and the other plastic on cylinder and if so where can i get them...

[@bam6972]

the orings i got from a hardware store. i got mine from fastenal for less thand a buck. thats all you need. just clean it out really good and your set. i could not get the big oring to seat on the inside so i just reused mine. just replace the cap oring and your good to go. mines still working today.

[@Daluke61]

Thanks for this. Got a Craftsman 2 1/2 that's only jacking up a few inches. Not sure if it's a simple leak like the one in this video or something a little more complex. Regardless, this will definitely be of help!

[@bam6972]

hey no problem. usually its just a few seals that leak. not a problem

[@totaltek04]

I have the same jack as the one in the video but I've had it a long time and the model # can't be seen. It recently developed a problem and I took it all apart with pictures of every step. I got the o rings at a hydraulic place and now after it is all back it will not work. Anyhow I'm trying to get the repair manual for it but I need a model number. Can you let me know from your jack what it is? Thanks

[@bam6972]

I will try and look in the next few days and let you know what the model number is ...

[@bam6972]

yea must have damaged it. did you clean everything out with carb cleaner? mine still has not leaked one drop. try to get some stop leak jack oil and see if that helps.

[@alarconalarcon6762]

I have the 4 ton craftsman floor jack and it is leaking from the back piston. Do you know if there is such a thing as a rebuild kit for this particular jack? What do you recommend I do to go about trying to repair this jack?

[@bam6972]

if its leaking to the outside of the jack, then tear it apart and replace the rubber o-rings as I say in this video. and it should fix it. but you might have to take it to a mechanic shop to have the nut taken off with a huge impact. mine was a 2 1/8 inch socket very big.

[@danielyoung3083]

i have the same jack. it lifts without a load but wont lift a car. is this fixable? how did you get crafsman jack parts?

[@bam6972]

top if off with jack oil and see what happens. the rubber o ring that seals the cap was leaking on mine. got the o ring from my hardware store.

[@marq666]

I have this same exact jack. Where did you find the parts? The Sears website says they do not sell rebuild kits because of the liability.

[@bam6972]

i got the o rings from fastenal take old oring to them to match it up. only like 30 cents

[@robertomartinez8071]

Model jack is ?

[@microwav]

My Snap-On floor jack has a bottle with a hex nut like yours AND I can't get it to budge. The cast steel body is clamped securely in my vise (cushioned with aluminum bars). 1st I used my 3/4" breaker bar with an 46mm impact socket. No rotation. Next, I used my electric impact wrench. Again, NO JOY. Now I'm beginning to wonder if the nut is left-handed thread. Do you remember the rotation you used to put the nut back on? ALSO, how much torque did you use to tighten the nut? Please save me from destroying my hydraulic unit! Paul

[@bam6972]

electric impacts aren't at good as air impacts. get somebody to let you use there 20 gallon air compressor and there half inch impact... it will come off. there standard right hand thread. with a good impact.. it will come off. I couldn't even budge mine in a half ton vise and a 5 foot breaker bar.... I about broke the vise and bench trying to get it off. I went to sears and had my buddy take it off with there impact tools... also when I put mine back on I only torqued it back on with hand tools in a little vise...

[@wiggsan]

Awesome!!

[@stanwardoshiro]

I didn't use brake cleaner, but I cleaned everything with rags/paper towels. I tried the hydraulic jack oil with stop leak and it still leaked. I will tear it apart again and inspect the o ring.

[@1s.s.hotrodvair]

I have a floorjack that would only pump two or three times then stop . So a friend of mine decides he is going to help me out and fill it. Well Mr. Genius , pulls up on the pad as he is trying to fill it up with oil. Now it really doesnt work. How do I bleed ALL of the air out of it?

[@bam6972]

if the jack was up when filling then its over filled big time. pop the cap then let the fluid rush out as the jack goes down. once its all the way down put the cap back on the fill hole. to bleed them just jack it all the way up then let it down. do this maby 15 times. it will get better overtime. never fill a jack with fluid that's been jacked up. it needs to be all the way down before you fill. otherwise it will over fill it and not want to come back down.

[@1s.s.hotrodvair]

Sounds good but when I pump the jack with the valve closed, as if to go up it mimicks the handle motion .up.... Down .... Up... Down . single stroke up then down. What's up with that? Its a large heavy model with an Allen set screw and another flat blade screw at the base

[@bam6972]

S.s. Hotrodvair not sure what you mean. if you could make a vid and post it on youtube maby I can help you better. I still think its overfilled. try doing what I said. pop the fill cap then open the valve and push the jack down. it should push all the extra fluid out. then simply just replace cap and try it then.

[@followyourbliss101]

I've got the same model that had been leaking for a few years and finally failed under use when my brother tried using it. Been meaning to rebuild the seals. Where did you end up getting the seals for yours?

[@bam6972]

Fastenal. any local hardware store should sell them for a few cents.

[@stanwardoshiro]

+followyourbliss101 Google search 2352 ShinnfuAmerica, they make a rebuild kit.

[@bam6972]

cool thanks

[@rkgsd]

Does anyone make a floor jack that doesn't leak?

[@tiagoalvaro53]

Amigo qual site posso encontrar os reparos??

[@RobertNazarov65]

My cylinder cap won’t come off at all. Starting to think it’s glued on

[@simonskydiver9018]

what is the model of the floor jack, because I have the same one and I need to know the model thanks.

[@stanwardoshiro]

+simon “azteca pride” skydiver It's a model 2352 by ShinnFuAmerica

[@forbiddenlovealive]

hi bam6972 my jack was leaking from piston as well.I removed piston and stuff. There was no o-ring around or no sign. Is it possible oil might have lost its viscosity or some impurities around piston giving clearance for oil to leak ? thanks

[@bam6972]

anything is possible. try some jack oil stop leak. wal mart and royal king has it. I think auto shops carry it aswell.

[@forbiddenlovealive]

bam6972 thanks man actually it's done. There was an o ring in the cylinder. Replaced and works fine. Only thing it took long to get proper pressure back I think.

[@bam6972]

cool

[@broncogabe32]

Where and how do you fill the oil in this jack at?

[@bam6972]

follow the jack handle down to the jack. there should be a rubber plug on top of the cylinder. pop it open with the jack fully down. keep adding jack oil till its just barely at the top.

[@DWCman44]

I have the exact same jack, where did you get the plastic seal and o-rings? I got the jack apart and plastic seal is trashed but don't know where to find a plastic seal. Your help would be greatly appreciated.

[@bam6972]

I didn't replace any plastic seal. it was just the one big o ring. I got mine at festenal. but any hardware shop should have them.

[@stanwardoshiro]

+David Coyle Google search 2352 ShinnfuAmerica. They make an overhaul kit.

[@73superglide62]

what if it ben in a fire and paint burn off oil burn uout

[@zbrooklyn]

wow thanks for the vid where did you get the seals from and what was the size of the o-rings you got for the jack

[@fujiobass]

How did you open the big nut ? I'm having hard time to open that big nut. need help.

[@bam6972]

2 1/8 inch socket on a half inch impact. call your local mechanic shops and see if they have the socket and the will zip it off for free if your nice.

[@psychoskippy2000]

I loosened the screw on the right until fluid came out, it was so dirty I didn't see the sticker that says don't adjust and now its not working. Did you have to adjust the jack after you replaced the fluid?

[@bam6972]

nope never messed with those screws. try and put the screw in about where it was and hopefully it will work. if not maby you got a lot of air in it. try popping the rubber cap off and add some jack oil.

[@psychoskippy2000]

bam6972 I heard a pop but I got it to work but it wont go down all the way now. oops

[@bam6972]

P Skippy umm did you have the jack up aways when you added oil? if so that's y it wont go down.

[@bam6972]

@therockkkkher its over filled then. just pop the cap and let it down. the fluid should spill out as it goes down. then take a bit more out until its at the bottom of the hole. should work then.

[@Gabe-ss1hi]

I need help i accidently twisted the pole too much when lowering my car and now the jack wont lift anymore any ideas on what to do

[@bam6972]

+Gabe try turning it all the way to the right. or something may have snapped inside I'm not sure. start taking it apart and see...

[@Gabe-ss1hi]

+bam6972 ok thnks looks like the screw came out and now its leaking oil

[@mobileautorepairbypacheco1806]

I try to see the jack part # on the video but I can see it, the reason why I ask this because I bought 2 used floor Jacks exactly like that one but whiteout the sticker information

[@bam6972]

+PACHECO MOBILE AUTO REPAIR no need for part numbers. take it apart and take the oring to a parts store or hardware store and they can match one up for you cheap.

[@stanwardoshiro]

I tore apart the floor jack several times (each time the jack leaked and I had to dump the hydraulic fluid). I double checked the o-ring and it was good. I noticed some scratches on the ram, so I spent 3 hours polishing the surface. This seemed like stopped the leak. I tested the floor jack over several days: ram all the way in, ram half-way in, ram all the way out. My floor jack started leaking again when the ram was extended all the way out.

[@bam6972]

yea its prolly time for a new one then. but you don't store your jacks with the ram out. you store them with the handle or screw half a turn out so it doesn't build up pressure from being cold then warming up and pushing past the seals. try filling it back up and then storing it with handle always half a turn out.

[@flisko123]

+bam6972 mhm, did it start to leak cuz of that? i bought used jack for pocket money which was working normaly for like a month then it started to leak, eveytime i stopped using it i tightened the bolt quite hard with which you release the pressure, so it drops down

[@stanwardoshiro]

Replace the seals. I would check to be sure there is no scoring on the surface of the ram.

[@flisko123]

+Stanward Oshiro i bought paper gasket for 50cents and put in between, but it still leaks, gonna buy some flat o ring on monday, if it still wont fix the leak then i will buy a new jack, probably took it apart like 10 times already lol

[@stanwardoshiro]

Don't give up! I did the same, gave up on 2 Craftsman floor jacks. Bought my 3rd one. Then came across the repair kits for both. Now I have 3 working floor jacks and I ain't complaining!

[@hardheadedss]

I have the same jack, but its not leaking it has fluid and wont stay lifted.. Do you know what screw i can use to bleed it?

[@bam6972]

shouldn't have to bleed it. bleeding it is just pumping it up fully then letting it down slowly a few times. if its bleeding down when lifting a car then its the piston inside that is all scored up. at this point I would just buy a new one.

[@hardheadedss]

Ok thank you

[@richardbutterfoss2353]

Thanks

[@Satchmoeddie]

The valve body on mine is peeing oil all over the place. Jacks up fine, put weight on it and the oil runs right out the filler cap, or somewhere.

[@bam6972]

the piston inside has cups to seal against the cylinder and if the cylinder is scored up or the cups are torn then it will leak down past the cups. and if overfilled push some oil out past the seals. take filler cap off then let jack all the way down. add jack oil and try it out. does the jack slowly go down with weight on it?

[@bryhne]

where did you buy the rubber seal?

[@bam6972]

fastenal any hardware store that sells orings

[@juliousdavis8105]

Hey same jack I have. 😂 They should have recall

[@chuaongpacpo9801]

Mine is exactly the same this floor jack, but mine lost model & serial numbers so any one please give me one Thanks

[@chuaongpacpo9801]

Mine is exactly the same this floor jack, but mine lost model & serial numbers so any one please give me one Thanks

[@valeriegray2586]

where do u buy o rings

[@bam6972]

fastenal should have them or any autoparts stores

[@stanwardoshiro]

I have that exact same floor jack. I bought the actual seal kit from Shinn Fu America. I installed it, and the jack leaked about a month later. I think I may have damaged the o-ring upon installation.

[@zell863]

Most likely you didn't oil them when did installation. They tear at first movement of rod.

[@stanwardoshiro]

Zeljko Situm actually, what I found out was the piston got scratched the first time around. I used the floor jack on the gravel and scratched the piston shaft. Since it leaked after the first seal replacement, I disassembled it and sanded the piston using a shoe string and different grits of sandpaper. Eventually making my way to 1000 grit. I then ordered a variety of different size o rings that are slightly larger than the OEM. Floor jack hasn’t leaked since.

[@HAMIDNY]

Hey buddy , where did you buy the o rings from ? And what kind of fluid did you use

[@bam6972]

I got the o rings from Fastenal. and I used jack oil with stop leak found at wall mart in there automotive section. still not a drop has leaked out after almost 3 years.

[@jasonn2284]

Genius. You should be a teacher

[@bam6972]

yea that's what I would do. and check for hairline cracks

[@beingsneaky]

did you purge the air after fixing it?

[@bam6972]

just by moving the jack up and down fully a few times purges the air.

[@beingsneaky]

hmm most instructions i have seen say to open Valve and then pump 10 - 20 to purge the air. good to have the fill plug open too to watch for air bubbles.

[@bam6972]

yea that works too. either way works fine.

[@harryrivera9605]

COULD YOU SHOW ME HOW TO ADJUST IT, REMOVE AIR.

[@bam6972]

no adjustments and to get rid of the air pockets just keep jacking it up to full then release it slowly. do that a few times and its done.

[@73superglide62]

will do waiting 4 computer to upload don't like the phone thing ,lol

[@73superglide62]

this is a aluminum piece on the end that spinning a round no grove for a seal that I can see

[@73superglide62]

have habor feight Trans jack need seal kit

[@bam6972]

take the orings out and take them to your local hardware store. they should be able to match some up for you.

[@73superglide62]

Do you show the in side of the jack

[@bam6972]

not in the video. but its not hard at all. just pull the plunger out and clean really good and stick it back in and get new o rings to seal the case together. but if its been in a fire then the plasic plungers are probally melted. I would just throw it away at this point.

[@73superglide62]

up date just got dis a seable it ,she rusty and all oil burned up witch wood think ,question on the piston is there oring or just metal plunger on the shaft

[@bam6972]

they are a plastic cup like seal if I remember right. in a fire it would of burned up.

[@calholli]

you play guitar dont you...... its the only excuse for nails like that

[@bam6972]

[@flisko123]

+bam6972 at 0:13 my jack is leaking at the bottom, below oil fill hole, there seems to be no o ring in between oil fill round pipe and the part below, just metal to metal, is that how it is supposed to be? also holds under pressure, just leaks when not in use

[@bam6972]

it might be welded together. and there might be a crack in the weld that is causing it to leak.

[@flisko123]

+bam6972 it came apart rly easy, dunno if it was welded before, doesnt look like it tho, was thinking of buying flat o ring and putting it between you probably dont remember, but was there any seal there?

[@bam6972]

im not sure its been so long ago. I still have the jack and its not leaked one drop.
