Walker 1-1/2 Floor Jack

[Sparky747]

First off .....Hi Everyone, this is my first post so hello to the community.

I have a 35 plus year old Walker Floor Jack, which was first
I ever owned, now I have a few other used ones that I was given, and I was able to repair.

Back in the day I use to eat my heart out, wishing to have a floor jack of my own. My Walker was bought for me as a gift by my former girlfriend from years ago.

Anyway, I just would like to know if anyone knows why the jack seeps down while under load, I would rather not pull it all apart unless absolutely
necessary.

This jack has never been apart, so I would like direction on where is most likely the problem, the jack still has steel cover slugs over the check ball ports, so if need be I will remove them, but not unless necessary.

Any information would be appreciated.

The jack does not leak externally.

Thank You

I have heard the relief valve adjusting screw can back off from years of vibration. Or possibly a bit of **** under a valve seat. A buddies jack, different make, drifted down. We took the guts out of each port, drained all the old oil out, and flushed the ports with penetrating oil. Put it back together with the same parts and leak down was gone. Sometimes you get lucky.

It needs to come apart, don't waste any more time trying to diagnose. The first thing I would check would be the leather piston cup on the main ram. It's one of the few seals that can give you catastrophic failure under load as they can wear a hole in the base of the cup. Regardless, at 35+ years of service, the best option is to put eyes on the individual components.

New to the board and thrilled to see this post. I have a similar Walker with the same problem.
