5. Inspection of the accessory drive pulleys should include inspecting for bends, dents or other damage that would prevent the drive belt from seating
properly in the pulley grooves or on the smooth surface of a pulley when the back side of the drive belts are used to drive the pulley.
6. Accessory drive component brackets that are bent or cracked will also cause the drive belts to fall off.
7. Inspection of the fasteners can eliminate the possibility that an incorrect bolt, nut, spacer, or washer was installed. Missing, loose, or incorrect
fasteners may cause pulley misalignment from the accessory drive brackets moving under load. Overtightening the fasteners may cause
misalignment of the accessory component brackets.
