I rebuilt the pump, and touch control block with the kit I got from local Case IH dealer when I was a parts guy there. Replaced both filter screens, springs, and little plastic valves. Filled with Hy-Tran. Cycled the living daylights out of it: three years running a sickle mower in the waterways, planter and cultivator and side dresser in the garden, mower deck in the yard. So I know there's not air in the system. It's not leaking into the crankcase. Oil level is fine.
It lifts perfectly. Lowering pulls the engine down bad. When the engine is cold, it is enough to kill the tractor. Don't have access to a pressure gauge, but thought if anybody had any ideas or if this topic has been discussed earlier...
