## Discrepancy

NR 1 BEARING SEAL SCAT IS A CHROME FACED SEAL.  ONCE THE CHROME IS REMOVED, THERE ARE CRACKS IN THE BASE METAL DETECTED BY FMPI.  USUALLY LIGHT MACHINING WILL REMOVE THESE INDICATIONS, BUT THIS CONDITION APPEARS TO BE GETTING WORSE ON THIS PART.  THE CRACKS IN THIS PART CANNOT BE REMOVED.
