I agree that other leaks should appear but the Clark was an electric unit & the tilt, s/s & p/s were all powered by the main hyd pump on this unit yet none of the other systems leaked. My theory was the hoist was the only circuit that accumulated oil rather than just use the pressure.

I think I would err on the side of caution & drain the hyd tank & check for debris at a minimum along with checking the pressures. I would think that high pressures would also cause other cyl's to leak or have other symptoms.

Do Linde's have a high pressure filter after the hyd pump? Do they use the hyd pump to power the hydros or do the hydros have their own pumps? Not trying to break your b*lls- just don't know how they're set up.
