I just picked up an older Komatsu PC75uu-2. The previous owner said it needs pump work. Took it home and sure enough, I got 2,200 psi on 1 valve manifold block and 0 psi on the second valve manifold block. The third manifold block comes off the gear pump at the end of the piston pump and that one was at 3,000 psi. I actuated the track levers for testing the main manifolds as to avoid throwing the pilot lines into the scenario. Has anyone tried rebuilding a PC75uu-2 main pump themselves? And if so where did you source your parts from? The dealer wants an obscene amount of money for OEM parts and I don't want Chinese parts if I can avoid it. Any suggestions would be great.
Thanks,
Jon
