I bought this machine with a non working hydraulic pump, and put in a reman pump. The engine stalled frequently under normal operation. The new pump failed at approximately 200 hours. The instrument panel/monitor is not working. I am guessing that the controller and/or monitor are not working properly, and therefore the TVC valve is not de-stroking the pump. The people rebuilding the pump are saying it may be the main relief valve, but because of the electrical issues, I am thinking otherwise. Anyone have any knowledge to add? Any other thoughts? Thank you, Steve
What failed in the new pump? Is there a lot of brass shavings in the bottom of the hydraulic tank? Do you have a warranty on the new pump? Have you checked that the diodes light up on the computer? Does your machine have a three position mode switch or a two position one? Have you made sure the banjo bolt strainer on the fuel transfer pump is clean? Have you checked the TVC solenoid coil with an ohm meter looking for a resistance reading? What is the general condition of the wiring harnesses in your machine? Can you describe any other problems the machine might have had before the pump failed?
