The Gates Belt Wear Gauge assists serpentine belt inspection. The small, lightweight tool assesses material loss between belt grooves and provides instant pass/fail results. It can be used on any open, straight surface on the belt and also can be used one-handed, on or off the vehicle, and in hard-to-see places. Technicians press the tool into the belt grooves with light pressure, and then attempt to rock the gauge in a lateral motion. If the gauge remains tightly seated, the belt has sufficient service life remaining. If the gauge allows lateral rocking movement, it indicates that the belt ribs are worn enough to allow belt slip and the belt should be replaced.
