3 ton floor jack repair

I made the mistake of leaving my floor jack in the up position with no load on it for about a week and now after letting the jack down it is very week and will barely pump up the piston. Any advise to fix this?

3 ton floor jack repair

If its full 0f fluid and doesnt need bleeding, could be "bypassing" internally. Time for new "O" rings, may even need to be honed. If you cant do it look for a shop that specializes in hydraulics or even a hose shop. Might cost a few bucks, but I had a 7 ton unit overhauled for 1/3rd the cost of a new one.

May just be just rust on the cylinder rod that was exposed while it was up that long
Clean the rust off with WD40 or something..no NOT sand it off
