Pulley Installation
Correct accurate installation of V-Belt Pulleys is essenial to provide long life of the belts. Pulley alignment and parallelism are
very important as any misalignment of the pulleys will cause unequal loading in the belt and cause edge wear on the belt.
Pulley alignment can be checked by placing a straight edge across the outside edge of the pulleys, and adjusting until contact
occurs evenly across both pulleys.
