A. The poppets are not operating when the wheels are turned full left and right to the axle stop (for an extended period). The pump relief valve is working all the time and creates an overheating condition in the system when the poppets are not working. Check that axle stops are set to OEM specifications and reset the poppets. 1? clearance is recommended. See Poppet resetting procedures TAS101 Service Bulletin or Service Manuals.
