Need some input....
NAA runs good, but I've got a noise in the hydraulic pump. Quiets somewhat at mid RPM but much louder at idle. Kind of a tick-tick-tick scraping type noise.
Took the pump off this afternoon to confirm and started the tractor. Definitely the pump. While I had it off, I checked for play in the gear. Tight and no play. Turned the pump gear by hand several times, no unusual or odd noises.
Do have some wear on the pump gear:
Cam gear looks good, and is also tight. But I did note that it is not centered in the drive hole in the block. Very little end play though on the cam shaft.
Any ideas on my noise? I can rebuild the pump but hate to have to. It works well other than being noisy.
