I rebuilt my old one after loaning it(!). Rebuild was simple:

I hate to tell you this, but those things are not really worth fixing. You
can see a teardown of a similar model on youtube. Everything is just swaged
together, it's not designed to be repaired.

There's a reason why a proper jack with a chromed piston is more money.

Default How to refill a leaking Sam's club "Michelin" floor jack

Thank you for this old thread. Its 2017 -Definitely helped revive my 15 year old jack. Same here the fill and bleed method did nothing. That far screw you explained definitely did the job. Just like new. No seal leaks just needed that fill and adjustment in the right spot you pointed out. Again, very helpful.

Default How to refill a leaking Sam's club "Michelin" floor jack

Replacement parts for this jack can be found at Lazzar's Floor Jack: HCRCnow.com

Someone said these jacks are not worth fixing, but my math says they are. I've had my jack for almost 20 years and just recently had the first problem with it ever... The universal joint that opens and closes the lift valve broke. About $125 for a new jack vs. $26.35 for a Universal joint kit and about the same for a seal kit.
