4100 hydraulic problems

[outlander54]

Update
I finally had time to drain the oil this weekend. Cleaned the suction screen, it was dirty with small particles and the magnets had a metal sludge around them. Replaced the filter and filled it with new oil. The oil coming out of the rear screen drain was clear. The oil from the two brake drains and the drain by the mid PTO had a white tinge to it. So there was some water there.

The oil was in a heated area so when I started the tractor up everything worked fine. The power steering worked first time. I figured the real test would be the next day after everything got cold over night. Sunday went out to snow plow and the power steering worked right from the start and the plow went up and down nice and smooth. Used it again tonight and everything is still working fine.

The oil had 220hrs on it since the charge pump was replaced two years ago.

Hi Kenny
From the CD manuals I have it shows there is a hydrostatic pump and a charge pump. On the 4100 the power steering comes from the charge pump, I believe on other models there was a separate pump. Oil from the 4.2gpm charge pump (gear unit) goes through the steering control pressure control valve set at 270psi to the power steering control valve. The variable displacement piston pump (12.6gpm) only feeds the hyrdostatic motor. I can forward pdf pages from the Tech manual if anyone needs them.

If you would be so kind to forward me the pdf of the hydro on my JD 4100, I would appreciate it.
Thanks
Jack
