About This Product
This oil pump drive gear is a hard-working part of the pinion shaft assembly. It fits a wide range of Harleys, including 1937 to 1973 45" Sidevalves and 1954 to 1977 K, KH, and XL Sportster models. Produced by Samwel, it replaces OEM 26318-37. This gear is responsible for transferring power from the crankshaft to the oil pump, making it the heart of your engine's life-support system. Whether you're building a vintage Flathead or a classic Ironhead, this gear provides the durability and precision fit required for long-term reliability and consistent oil flow.
