About This Product
When you are running a 3-inch open primary on an early Big Twin, you need a front pulley that can handle the torque. This Belt Drives Ltd. 47-tooth front pulley is designed for 1937 to 1954 Big Twin models equipped with a tapered sprocket shaft. It features an 8mm pitch and is built with the precision you expect from BDL. The tapered fitment ensures a solid connection to the crankshaft, which is vital for high-performance belt drive setups. Whether you are building a period-correct chopper or upgrading a vintage rider, this pulley provides the durability and alignment necessary for a smooth-running primary drive system.
Manufacturer part number: 47T-3.
