Masterdrive 10.5" 2 Piece dual groove cast iron pulley/sheave with 1" H bushing for A section belts. This is a high-quality 2-piece pulley that measures 10.25" outside diameter and is designed to be used with an H-style bushing. This 1" bushing (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 making this style of pulley much more secure than a standard single-piece pulley. This listing includes an H bushing to fit on a 1" shaft. The bushing itself is made of solid steel and is precision machined to ensure high quality and secure attachment to your motor/engine shaft. This pulley accepts A Section also known as 4L series belts. These belts are 1/2" wide.
