I am looking at the 3 pt hydraulics on my 580B with an eye toward pulling the 3pt off to split the tractor, then install my hoe. What I found appears to be a secondary relief valve, installed, I assume, because the primary R/V failed. So, how to go about a legitimate fix? I can't seem to locate a parts schematic for the valve, so I can't disassemble mine to see if it is missing anything. I suppose I could just put a QD on the extra return line, or just plumb it back to before the existing QD on the existing return line. Any more ideas?
