may of been damaged, which caused the drive belt to fall off. Inspect the belt for cuts, tears, sections of ribs missing, or damaged belt plys.
4. Misalignment of the pulleys may be caused from improper mounting of the accessory drive component, incorrect installation of the accessory drive
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.

Drive Belt Excessive Wear Diagnosis
Drive Belt Excessive Wear Diagnosis
Diagnostic Aids
Excessive wear on a drive belt(s) is usually caused by an incorrect installation or the wrong drive belt for the application.
Minor misalignment of the drive belt pulleys will not cause excessive wear, but will probably cause the drive belt(s) to make a noise or to fall off.
Excessive misalignment of the drive belt pulleys will cause excessive wear but may also make the drive belt(s) fall off.
