Masterdrive AK84H 8.25" Cast Iron A Section Pulley

Brand new single groove 8.25" cast iron pulley for an A section belt. This is a high quality pulley that measures 8.25" outside diameter and is designed to be used with an H style bushing.

The bushing (Not Included) inserts into the center of the pulley and slides over the shaft. As you tighten down the bolts on the H bushing it will tighten down on the shaft. This style of pulley is much more secure than a standard 1 piece pulley. 

This pulley accepts A Section also known as 4L series belts. These belts are 1/2" wide.
