    580 B Hydrolic pressure

    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.

    Control valve leak

    Is this leak worth repairing ? it's not real bad but it bothers me and makes a mess, Not sure how to go about removing the plunger from the fit though. I think it's only an o ring or two but not sure how to tackle it or if it's worth the bother.
