## Discrepancy

(CAN) IT WAS FOUND WHEN THE MAG WAS ASSEMBLED NEW, THE HIGH TENSION TAB OF THE COIL WAS NOT MADE PARALLEL WITHIN THE HOUSING SPLIT LINE.  THIS CAUSED THE BRUSH TO WEAR A DEEP GROOVE INTO THE TAB.  THE BRUSH (10-160844) ALSO RECEIVED DAMAGE IN THE FORM OF A STEP GROUND INTO THE SIDE OF IT FROM THE SIDE LOAD IMPOSED BY THE BENT TAB.
