The number of belts required for an application is obtained by dividing the design horsepower by the corrected horsepower rating for one belt. The corrected horsepower rating of one belt is obtained by multiplying the horsepower rating from Tables 9 through 12 by the arc of contact correction factor and by the length correction factor.

V-Belt Installation, Maintenance & Storage Installation 1. Check pulleys for rust, oil, grease, dust, dirt and other foreign materials. Clean the pulleys. Foreign materials accelerate belt wear and dramatically reduce belt life. Dirt and dust lead to slippage. Oil and grease reduce belt traction and destroy the belt surface. 2. Inspect pulleys.
