Masterdrive dual groove 5" cast iron pulley/sheave with 1-3/8" H bushing. This is a high-quality 2-piece pulley that measures 5" outside diameter and is designed to be used with an H style bushing. The 1-3/8" 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 1-3/8" shaft. The bushing is made of solid steel and precision machined to ensure high quality and secure attachment to your motor/engine shaft. This pulley accepts B Section also known as 5L series belts. These belts are 5/8" wide.
