## Discrepancy

DISASSEMBLED WHEEL TO INSPECT AFTER A CRACK WAS NOTED IN THE OUTBOARD WHEEL HALF.  REMOVAL OF PAINT REVEALED A CRACK RADIATING FROM A LIGHTENING HOLE INWARD TOWARD THE BEARING RACE AT A 45 DEGREE ANGLE AND ABOUT 1.5 INCHES IN LENGTH.  FURTHER INVESTIGATION REVEALED THAT A PERMANENT WEIGHT HAD BEEN REMOVED FROM THE INBOARD WHEEL HALF AND REPLACED IT WITH 5 LARGE AREA WASHERS AND AN INCORRECT RETAINING BOLT.  THE BOLT IS TOO LONG AND CONTACTS THE OUTBOARD WHEEL HALF AFTER ASSEMBLY.  TORQUEING OF THE WHEEL BOLTS DURING ASSEMBLY CREATED A STRESS POINT RESULTING IN A CRACK.
