Inspection



Belt replacement under any or all of the following conditions is required:



Excessive wear
 
Frayed cords
 
Severe glazing
 

Poly-V Belt system may develop minor cracks across the ribbed side (due to reverse bending). These minor cracks are considered normal and acceptable. Parallel cracks are not acceptable and require belt replacement.


NOTE
Do not use any type of belt dressing or restorer on Poly-V Belts.
