Rebuild depends on design and availability of parts. If the seals
are all orings, you are in luck as long as metal parts are not worn
badly. I think some jack pumps use a cup in the pump, and it may be
hard to find replacement cups.
I have worked on hyd cylinders that are in the range of 100 years
old, but still perform regular duty made with leather cups. The
leather cups are available. The cylinders run and work ok at 2000
psi. One I saw being operated at 2750 psi on an 8" cylinder. that
is 16 pi x 2750 or 70 tons on a piece of leather.
I have a really old hydraulic floor jack with a leaky cylinder,
have thought for some time to try to rehabilitate it. Are those
similarly arranged?
I think they can be repaired, but I've never done one.
