## Discrepancy

REAR BEARING LEAKS AT THE SCAVENGE LINE BOSS.  REPLACED BRONZE CRUSH SEAL TWICE WITH NO SUCCESS.  IT WAS FOUND THE REAR BEARING HAD A SMALL NICK WHICH PREVENTED THE CRUSH SEAL FROM SEATING PROPERLY.  SUSPECT SOMEONE NICKED THE REAR BEARING WHILE CLEANING COKE FROM MODULE 4.  REPLACED WITH NEW UNIT(S) CORRECTED PROBLEM.
