M7 Hydraulic pump whine

[jlindlsy]

My m7-131 does not whine at an idle. But if you have any RPM's on it and lift the or tilt the loader I get a pretty bad whine. Is this just the big pump or the load sensing, or is this something I should get checked out. It seems to function properly. However, I just bought this tractor and what seems proper to me might not be.

Several things can cause the pump to whine. First make sure it isn't low on hydraulic fluid. Next I would change the filter. Pump whine can be caused by starving the pump of fluid.

Thanks for the reply, I have ordered all new filters. Going to check ge them when I get them. Also, I just bought this tractor, I am not sure the oil in it is UDT2 I hear that can make a difference as well. Thinking of changing it. It is probably even worth the price e.
