## Discrepancy

DURING MAINTENANCE ACTION, FOUND LT IMPULSE COUPLING MAG GEAR ROLLER BEARING CAGE, PN LYC 67542 DISINTEGRATED AND DEPOSITED IN OIL SUMP.  BOTH SIDES OF ROLLER CAGE CAME LOOSE AND ROLLER BALLS BUNCHED UP INSIDE BEARING RACES.  ADDITIONAL STRESS OF IMPULSE MAGNETO MAY CONTRIBUTE TO DEFECT.  RT MAG ROLLER BEARING, OK.
