Timing belts are often replaced as part of scheduled maintenance or when inspection shows wear. Check the belt for cracked teeth, exposed cords, glazing or missing teeth. Also inspect the pulleys for worn grooves or debris. If the drive uses more than one belt, replacing them as a set helps keep the drive balanced.
