I'm trying to replace the little rubber washer in the (think its called the pressure valve) that is on the right side (near the oil pressure gauge) on the pneumatic lift all. Anyone know the part number for it. About 8 years ago I got one from my local CaseIH dealer and it was still available.
Liftall works still, but will not stay up, drifts down immediately. I think this rubber washer is the pressure leak.
