john deere 4620 tractor has hydraulic issues Problems

A hydraulic problem appears.First it was the hoses and pipes, then the control valve, now it seems like the drive pump needs to be changed along with the hydraulic pump.The worst symptom is that things that require hydraulic pressure to function don’t seem to be getting enough pressure.Can the tractor be changed without losing the pilot bearing on the job?

If the tractor has a Syncro transmission system, the transmission pump repair does not require splitting the tractor. Have you checked the flow and pressure of any of the pumps? Have you checked and cleaned the hydraulic oil pan screen?

Place a container under the opening, remove the hydraulic filter, crank the engine for 30 seconds, and see how much oil you get. To check the trans pump on the SR trans one has to lift the rocker axle box to access the pump.
