Farmall 504 Hydraulic problems

David Glenaman · May 25, 2013

I have a 504 with very little pressure coming from the remotes. The 3 point lift and power steering work fine, I took the remote valves apart and cleaned them. No help. Any ideas please.

Those had a "double" pump- 2 sections, 2 impellers, two outlets. As I remember, the remotes were off one section, and the PS and 3 point off the other. You need to measure pressures off the two output hoses - sounds like half the pump is bad. I have one, that I think is good, but would need new gaskets (I took it apart, thinking it was bad, but the problem turned out to be something else, so I think the pump is good). Email me at mmittge at compprime dot com if you want to explore it further.

The flow divider orfice is a pressed in disk. It often turns sideways or comes out and then all flow goes to power steering from front pump and none to aux valves. It is right behind the hose coming into flow diver valve from pump.
