M5700-loss of power steering after running awhile

[North Idaho Wolfman]

Are you operating it with the three point in a full up position?
Go to the tractor and start it, raise the rpms to where you normally work with it.
Lower the three point wait a min, then raise the three point to the top, does the hydraulic noise change, and do the rpm's drop slightly?
If so then the feed back rod needs adjusting.
Also do this test with the draft control off and draft control on.

Thank you for the information-I will check all these out this weekend when I'm with the tractor next

If you measure pressure at the loader valve inlet it will definitively answer all those questions. No guessing.

All it takes is a gauge, a tee fitting, and maybe 5 minutes time.

I am borrowing our hydraulic pressure test kit from work that has multiple fitting, gauges and hoses and will post up what I find.

Do you know where and how to hook the gauge up?

I know where the loader valve is-I am looking for pictures now to make sure I know which side is the inlet because when I get out to the ranch cell service is almost non-existent

I repeat, do you know HOW to hook the gauge into the inlet?

Disconnect the inlet line, find the correct T-fitting, thread the T fitting onto the inlet line and loader valve, thread the 3,000psi gauge into the top side of the T-fitting?

You got it.

To test start the tractor and read pressure with engine at idle and 3pt fully lowered. It should not be more than a few hundred PSI if that. Then raise the 3pt to top and verify pressure remains in that same range

Thank you-I will report back what I find

Poor man's pressure tester.
