## Discrepancy

DURING COMPANY ROUTINE SERVICING/GREASING OF NOSE WHEEL ASSEMBLIES, THE INBD AND OTBD GREASE SEALS WERE FOUND DAMAGED.  THE GREASE SEAL HAD FLAT SPOTTED AND WAS NICKED IN A COUPLE OF PLACES.  THE BEARINGS THAT ARE LOCATED IN THIS AREA WERE FOUND DAMAGED.  THE BEARING WAS VOID OF FUNCTIONAL GREASE AND HAD OVERHEATED THE OUTER RACE (OF THE INBD WHEEL HALF) TO THE DEGREE THAT HEAT TRANSFER WAS EVIDENT TO THE NOSE WHEEL ASSY HALF.  IT IS THE OPERATORS BELIEF THAT BRG FAILURE WAS EMMINENT.  THE MFR HAS BEEN NOTIFIED OF THIS POOR INSTALLATION DESIGN.
