## Discrepancy

SEAL RING UNBONDED FROM SHAFT.  THIS WAS DISCOVERED DURING A TRANSMISSION CHANGE.  SUSPECT POOR QUALITY ADHESIVE USED DURING MANUFACTURE.  THIS HAS BEEN A PROBLEM IN THE PAST.  SUBMITTER HAS REPAIRED THIS BEFORE WITH 1442 B 1/2 IN THE FIELD AND AT OVERHAUL.  SUGGEST BETTER ADHESIVE USED AT MANUFACTURE, AND THE SEAL RING MOVED .110 INCH TO .250 INCH LOWER TO BETTER ENGAGE THE SEAL.
