## Discrepancy

OPERATOR WAS COMPLAINING OF HIGHER THAN NORMAL OIL TEMPERATURES.  FOUND VERNATHERM VALVE TO HAVE BROKEN.  THE NUT THAT HOLDS THE SEATING VALVE HAD BROKEN OFF THE THREADED PORTION OF THE PART.  IT HAD BROKEN WHERE A ROLL PIN SECURES THE NUT TO THE THREADS.  THE NUT WAS FOUND IN THE OIL COOLER HOSE WHERE IT COMES OFF THE ACCESSORY CASE GOING TO THE COOLER AND HAD RESTRICTED THE FLOW ENOUGH TO THE COOLER THAT CREATED THE HIGHTER TEMPERATURE.  THE FAILED PART WAS NOT OEM BUT A MFG PART.
