Hydraulic Pressure

[CaribooHarry]

Finally got a change to check hydraulic pressure and I have 1500 psi at 1000 rpm.

What is acceptable pressure.

Depends on what model of tractor you have but unless it is a very early tractor it should be at least 2000psi at 2000 engine rpm. When new a valve would possibly be 2200psi. You must have the lift arms tied down so they cannot lift not just a heavy implement. A heavy implement must be heavier than the tractor can lift normally to get the valve to blow.If the tractor can lift the implement you will only get the pressure in the system needed to lift that implement NOT the blow-off pressure.....John (UK)
