The pulley essentially provides the connection from the crankshaft’s output shaft on the motor/engine to the belt, which in turn is connected to the compressor pump’s flywheel. The O.D. (outside diameter) determines the RPM of the pump, so be sure to choose the correct diameter pulley. There are typically one and two-groove pulleys, and pulleys that accept J-6 poly-groove (serpentine-style) belts and v-belts.
