Drive Belt Excessive Wear

Drive Belt Excessive Wear Diagnosis





Minor cracks in the belt rib are normal. They are the result of reverse bending around a backside pulley. Do not replace belts for minor cracks.





Belts that have chunking longer than 5 mm (13/16 inch) in one or more places should be replaced.
Belts should also be replaced if cord breakage or fabric separation is observed.
