## Discrepancy

WHEN CLEANING UP THE ACCESSORY CASE FOUND THAT THE SAFETY WIRE THAT SECURES THE OIL PUMP BOLTS PN 22537 WAS WORN THROUGH ON ALL 4 BOLTS.  REMOVED THE SAFETY WIRE WITH MY FINGERS.  THE WIRE WAS WORN WHERE IT ENTERED THE HOLES IN THE BOLT HEADS.  THERE DOES NOT APPEAR TO BE ANY CHAMFER IN THESE SAFETY WIRE HOLES.  THE ENGINE HAS ONLY 341 HOURS SINCE OVERHAUL.
