I got an 87 655 and everything works as it should but am wondering if its normal for the hydraulic pump to be noisy? It sounds like its got a wine like air is in the system. I changed the oil and filter, cleaned the suction screen. Is the pump just noisy by nature? I have no prior experience with these older hydro tractors as all the new ones i had made no such noise.

texasranger556, Thanks for the link, Yea that one on the video sounds just like mine. It must be in the hydro pump at the rear of the transmission making all the noise.
