V-Ribbed Serpentine Drive Belt With Cracks Across Ribs
6. Check the belt for cracks. Up to 15 cracks in a rib over a distance of 100 mm (4.0 in) can be considered acceptable. If cracks exceed this standard,
install a new belt.
V-Ribbed Serpentine Belt With Piling
NOTE: Piling is an excessive buildup in the V-grooves of the belt.
V-Ribbed Serpentine Belt With Piling
7. The condition of the V-ribbed drive belt should be compared against the illustration and appropriate action taken.
1. Small scattered deposits of rubber material. This is not a concern, therefore, installation of a new belt is not required.
2. Longer deposit areas building up to 50% of the rib height. This is not considered a concern but it can result in excessive noise. If noise is
apparent, install a new belt.
3. Heavy deposits building up along the grooves resulting in a possible noise and belt stability concern. If heavy deposits are apparent, install a
new belt.
