    Case 580B Main Relief Valve

    my relief valve does not seem to be adjustable. I mean by that, there is not a set set to lock into any one position. it appears, tighten until oring is snug, end. Is this correct? If you have an adjustable one, would you post a picture. does it look like mine in post 36?

    Case 580B Main Relief Valve

    Coy, I will get the number off the loader. Probably tomorrow. Sudnurge, that control body looks similar, but not the same. The valve in the pictures came from that spot you and arman posted. There was no access on the back side. I am going to out it all back together, then put a gauge on it...
