    What should the Hydrolic pressure be on this old machine ? There is no longer a gauge in place so I am curious as to how much pressure the pump is putting out. When I put a strain on the backhoe it slows down the engine so I am thinking the pump is still pretty strong. Thanks for the input.

    Your 580B rated pump output is 23 gpm at 2000 psi at 1900 rpm. Your loader valve main relief setting is 2200 +/- 75 psi at full throttle. Your loader with (bucket empty) full raise up in 4.2 seconds.
