## Discrepancy

DURING OVERHAUL INSPECTION OF FREE WHEELING UNIT, IT WAS DISCOVERED THAT THE BEARING OUTER RACE HAD ROTATED IN THE HOUSING. ALSO THERE WAS EXCESSIVE WEAR IN THE HOUSING INTERNAL DIMENSION.  WILL UPGRADE WITH BELL TECHNICAL BULLETIN 206-95-155 WITH SLOTTED OUTER SHAFT AND KEYED BEARING.  SUBMITTER STATED THIS SHOULD PREVENT THIS CONDITION IN FUTURE.
