504 hydraulic pump question

teachingscience · Nov 6, 2011

Does the main pump that powers the aux and power steering have a pressure relief valve in the pump or is the one in the flow divider for steering the only relief in the system?? Trying decide between a few ideas to plumb in a loader. The loader valve does not have a relief so want to make sure there is one in system when I"m done.

Thanks to all experts out there.

No relief valve in pump. Flow divider valve assembly has relief valve for steering only. Main relief valve is located in aux valve mounting block. Do not plumb in ahead of that relief valve. You need to go through your aux valves or add a power beyond plate.
