## Discrepancy

INSTALLED NEW SEAL AND WEAR SLEEVE FOR REPAIR LEAK AT INPUT SEAL.  NEW SEAL IS LEAKING AGAIN AFTER VERY SHORT TIME IN SERVICE.  A COMMON PROBLEM, BUT NOT SO SOON.  INSPECTION INTERVAL FOR GEARBOX IS 3,000 HOURS.  CHANGING SEAL 10 TIMES NOT DESIRABLE.  SEAL IS OF NEW STYLE AND PART NUMBER.  SUBMITTER STATED POSSIBLY A NEW MANUFACTURER.  ADVISED BHT OF THIS PROBLEM.
