So what was the original problem?

jds1956 · Jul 6, 2015

lift works but bobs up and down 6-12 inches at any level it is set at

jds1956 · Jul 16, 2015

fluid is seeping out of valve that is above the control valve
I assume this is where I am losing pressure and causing the bobbing action
also on the front side of the cylinder oil is dumping back into the belly of the tractor which I assume is ok at that point although it continues to drip a little with engine off and the lift with pressure on it from an attachment as it gradually falls to the ground. I cant see good enough on the front side of the cylinder to tell where the seepage is coming from

I guess I am going to have to start looking for a good cylinder to correct this problem as the picture states Do I have any other options????????

I guess some could still be coming out of the control valve also but it is hard to tell with it coming from valve above and running down onto the control valve also too
