Usage:
3500 Family Of Engines
Description of Change: A new spacer is used in the attachment alternator belt guard group. The illustration shows the location of the spacers. The new spacer has a smaller inside and outside diameter than the former spacer. The former spacer could contact the fiberglass guard in areas that were not reinforced with the embedded metal ring. This could cause the guard to crack. The new spacer can only contact the metal ring that is embedded in the fiberglass guard. The new spacer will improve the reliability of the alternator belt guard group.
