## Discrepancy

DURING THE OVERHAUL OF THIS ENGINE NEW ROLLERS (PN 5999) WERE INSTALLED.  DURING THE TEST RUN OF THE SUBJECT ENGINE ONE OF THE ROLLERS FAILED.  AFTER TEAR DOWN, A HARDNESS TEST INSPECTION OF THE ROLLERS WAS CONDUCTED AND IT WAS DETERMINED THE ROLLER THAT FAILED, WAS CONSIDERABLY SOFTER THAN THE REMAINING ROLLERS.  (SW15200313699)
