Takes about 40 minutes to remove the pump. You do not need to split the tractor to access the hydraulic pump. You will need to remove the top cover, access the pump and then strip it to The pressure in the system should be somewhere between 2100 – 2400psi. Obviously this reduces the overall pressure in the system and hence your pressure guage reading of 1500 – 1800psi. When one of the cylinders is not pumping efficiently it gives the symptoms of the linkage juddering up and down. This is most likely due to a broken ring or a stuck valve. It sounds like you have one or more of your pump cylinders pulsating. Pressure gauge test: gauge jumps from 1500psi to 1800psi at 2000rpm’s with both quadrant levers in up position. To lift implement off ground RPM’s must be above 1500. With or without implement the lift arms jump. Checked the fluid ( hyd.,trans., and final drive seem to use the same reservoir) Hydraulics acting like it’s starving for fluid? I not trying to tell you what is wrong but merely the things I have tried so far. I have done most of my own repairs but on this one I’ll need direction. Within the last 20 hours of use, the implements have began jumping up and down when carrying also using high rpm’s to clear the ground with implement. You have a very interesting web site on these tractors, I am having problems with the hydraulic three point lift. This shaking occurs both when the lift arms are raising and also when the lift arms are held at any point by the position control. Common symptoms are the need for high engine revs to get the tractor to lift and the normally smooth action of the lift arms becomes a shake or judder.
