Joe How hot does your 460 hyd get if the unload valve does not unload the system it well get hot enough to burn your feet through a goood pair of boots. If this is the case you will burn up the pump.

Make sure the unload valve is clean and good oring on it there is a very small orfice in the piston it must be clean. hope I gave some help.
