4. Inspect all drive belt(s) for signs of pilling. Pilling is the small balls, pills or strings in the drive belt grooves caused from the accumulation of
rubber dust.
6. Misalignment of the accessory drive pulley(s) may be caused from improper mounting or incorrect installation of an accessory drive component,
or the pulley may be bent inward or outward from a previous repair. Test for a misaligned accessory drive pulley using a straight edge in the pulley
grooves across two or three pulleys. If a misaligned pulley is found, refer to that accessory drive component for the proper removal and installation
procedure for that pulley.
10. Inspection of the fasteners can eliminate the possibility that a incorrect bolt, nut, spacer, or washer was installed.
12. Inspection of the accessory drive pulley(s) should include inspecting for bends, dents or other damage to the pulley(s) that would prevent the drive
belt(s) from not seating properly in the pulley grooves or on the smooth surface of the pulley when the back side of the drive belt is used to drive
the pulley.
14. Replacing the drive belt(s) when it is not damaged or there is not excessive pilling will only be a temporary repair.
