## Discrepancy

SCAVENGE PUMP HOUSING WAS CRACKED ON THE 2 TOP HOLES WHERE THE SCAVENGE PUMP BOLTS UP TO THE ACCESSORY CASE ON THE BACK OF THE ENGINE.  THE LOWER 2 INNER HOUSING BOLTS, NUTS, AND RETAINING LOCKWASHERS WERE OFF ON THE LEFT AND ONE-HALF OFF ON THE RIGHT.  THE VIBRATION FROM THE LOOSE LOWER 2 BOLTS PUT PRESSURE ON THE 2 TOP BOLTS CAUSING THE HOUSING TO CRACK.
