## Discrepancy

THE FLIGHT CREW REPORTED THAT DURING FLIGHT THE GEN 2 BEARING FAIL EICAS MESSAGE ILLUMINATED. THE MAINTENANCE VENDOR DETERMINED THAT NO2 DC GEN WAS DEFECTIVE.  THE DEFECTIVE DC GEN WAS REMOVED AND AN OVERHAULED GEN WAS INSTALLED.  GROUND RUNS AND OPS CHECKS WERE SATISFACTORY.  THE AIRCRAFT THEN WAS RETURNED TO SERVICE.
