M9540 PTO / Steering Hydraulic Line Noise

[SpecieTechie]

Hi,

The PTO/steering hydraulic line on my M9540 makes a noise as if there is cavitation. I have replaced the hydraulic pump, but the noise persists.

Is there any in line filters or relief valves on this line that could be causing issues? There is a FEL connected.

Cavitation is typically caused by oil starvation. The PS and implement pumps share a common supply so I would think both would have that problem.

There are reliefs in the PS controller.
