What was found
RETURN TO FIELD DUE TO L-GENERATOR INOP. TEARDOWN REVEALED THAT THE DIFFERENTIAL AND CLUSTER GEARS WERE SEVERELY DAMAGED BEYOND REPAIR. IT APPEARS THAT SOME KIND OF CONTAMINATION WAS INTRODUCED WHICH EITHER INTERRUPTED/DILUTED THE OIL SUPPLY TO ONE OF THE CLUSTER GEARS, OR DAMAGED THE PLATING ON THE SHAFT RESULTING IN LARGE AMOUNTS OF METAL INTRODUCED IN-BETWEEN BEARING SURFACES. THE CONTAMINATION COULD HAVE BEEN FUEL (OR SOME OTHER CONTAMINATE WHICH LOWERED THE VISCOSITY OF THE OIL), OR SOME OTHER FOREIGN PARTICLE(S) INTRODUCED EARLY IN THE UNITS LIFE. NO FUEL SMELL WAS NOTED BY TECHNICIAN DURING TEARDOWN. THE UNIT IS UNDERGOING A COMPLETE OVERHAUL.
