## Discrepancy

(CAN) BEARING INNER RACE SUPPORT WAS FOUND EXCESSIVELY WORN FROM BEARING ROTATION DURING 100MR INSPECTION.  H4D PULLEY ASSY WAS REPLACED COMPLETELY BEFORE FURTHER FLIGHT.  H4D PULLEY INNER RACE SUPPORT HAD APPROXIMATELY .0625 METAL LOSS/DETERIORATION FROM BEARING ROTATION.  NORMAL OPERATION CONSISTS OF THE BEARING BEING PRESS FITTED ONTO THE INNER RACE SUPPORT SHAFT.
