Working on this for a friend, Lift wouldn't really work much at all, noticed fluid pouring out around piston so removed cover and replaced oring and leather, and related gaskets and orings. Long story but also fixed water contaminated leak from trans into center housing. Back together with correct/clean fluid. Lifted fine but appeared to me that the piston was coming too far out of cylinder. I thought maybe that is why piston oring was cut, so I removed cover and adjusted rod to limit that, now it goes all the way up when first started, regardless of control handle position and sometimes won't respond up or down, very weird. I've bled system with hose. I really need some direction on adjusting this thing right. I have manual 19 but don't have the tools shown to make the adjustments shown. Thanks for any help. I'm a very experienced Auto Mechanic Senior Master with Ford and ASE, but I'm feeling pretty dumb right now.
