## Discrepancy

DISCOVERED DURING O/H THAT THE INCORRECT CENTERING CAM SET WAS INSTALLED.  ACCORDING TO CURRENT CMM DATA, THE PROPER PN IS GA58207.  THE CAM SET INSTALLED PN GA64000 IS MFG AND IS MACHINED AT A DIFFERENT ANGLE AFFECTING THE BREAK AWAY TORQUE FOR THE CENTERING ASSY.  WE HAVE COMMUNICATED WITH THE  ENGINEERING DEPARTMENT AND CONFIRMED THAT THESE PARTS ARE NOT INTERCHANGEABLE.
