The tractor runs fine but after 45 min to 1 hour the transmission case gets hot and the hyd pump seems to be blowing over relief. So I took the pump regulator apart and found the orfice plug for the unloader valve was plugged. so I unplugged it,clean and checked the other valves in the regulator and assembled regulator. Ran tractor found no difference. I checked the other control valves for proper one or two way flow detent postions, they were okay. Installed two new suction filters. Ended up taking out the spring for the unloader valve in the regulator. this seemed to stop the problem, but do not have hyd pressure for remotes. I would like some help to find root cause for the problem.
