component pulley, or the pulley bent inward or outward from a previous repair. Test for a misalign pulley using a straight edge in the pulley
grooves across two or three pulleys. If a misalign pulley is found refer to that accessory drive component for the proper installation procedure of
that pulley.
5. Inspecting the pulleys for being bent should include inspecting for a dent or other damage to the pulleys that would prevent the drive belt from not
seating properly in all of the pulley grooves or on the smooth surface of a pulley when the back side of the belt is used to drive the pulley.
6. Accessory drive component brackets that are bent or cracked will let the drive belt fall off.
7. Inspecting of the fasteners can eliminate the possibility that a wrong bolt, nut , spacer, or washer was installed. Missing. loose, or the wrong
fasteners may cause pulley misalignment from the bracket moving under load. Over tightening of the fasteners may cause misalignment of the
accessory component bracket.
