## Discrepancy

(CAN) UPON REMOVAL FROM THE WHEEL ASSY, THE BRAKE DISC WAS DETERMINED TO BE AN INCORRECT PART FOR THE WHEEL ASSY TO WHICH IT WAS INSTALLED. THE SUBMITTER STATED THAT THE CORRECT BRAKE DISC PART NUMBER IS 164-40 AND THAT THE ONLY PERCEPTIBLE DIFFERENCE IS THE DIAMETER OF THE MOUNTING BOLT HOLES.
