You will need seals from each photo I posted to correct leakage on rockshaft piston seal. Technically if 3pt controls valves are adjusted correctly & 3 pt is in lowest position then there should be no internal hyd leak if RS control vales seat IE control hyd oil as designed

Alright, i'm stumped. I got all the seals from my local dealer, and have the back piston cover off, but I can't seem to get the piston out. It's just sitting there, slightly revealed from the rockshaft housing. 3 point is all the way down, and lever is at minimum position.

Any tips to getting the piston out?

Crisis Averted - ended up using the 3 point arms like a deadblow hammer, Lifting the arms by hand and forcing them down. this popped the piston out little by little until i could grab it with my hand.

I ran the tractor for about 30 seconds and ran 3 point arms up and down several times to purge the air out of the system, and left the arms in the full up position to test leakdown. We'll see if the arms are still up in the morning.
