2090 movement issues

I had to replace the output shaft on the pto and clean out the shaving in the back end and replace all the springs in the flow divider valve. Then drain the oil after having water in the new hydraulic oil. Now thats done I have to rev it up to 2100 rpm in order to move forward or backwards the oil warning light comes and goes steering works fine . Any ideas

Any implement cylinder that you plugged your
quick couplers into, will now have contaminated
hydraulic oil, which can re-infect your system.
I have seen a hydraulic motor fail, in a sawmill,
and wipe out the pump with matallic particles.
Then..because they simply slapped on a new pump,
and motor...the new ones got wiped out in a matter
of hours. Third try, after replaceing pump, changeing oil and filters, flushing hoses and
cylinders, they got it right!

Check low pressure standby. Should be 325 to 350 psi. Then check high pressure standby. Should be 2300 psi. Then I would check the flow at the back of the tractor at the remote valve. While doing this shift the powershift thru the different power shift speeds. Low, intermediate and then high. Then in reverse. Flow will drop when you shift to a new speed but then the flow should recover after the clutch pack fills. By the way the steering is fed off the small gear pump behind the piston pump.You probably have a bad leak either in the powershift or the cv2 valve.
