500-6 8466 hrs, no function or pump noise at all, pilot pressures check out good, shut off valve is good, thru the monitor panel pulled up real time data work pump at 2.0 mpa, 170cc/rev, and control voltages are good. is there another test for the main pump and main relief valve?

    Where are you checking the pilot oil?

    I checked at the ppc strainer, ppc accumulator and shut off valve output hose.

    Did you get your loader figured out yet?
