901329 Return gear, driven. oil pump

This driven return gear is a staple for anyone working on vintage Harley-Davidson oiling systems. It fits a wide range of Big Twin models from 1941 through 1967, making it the correct choice for Knuckleheads, Panheads, and early Shovelheads. As the driven component on the return side, it’s responsible for the critical task of scavenging oil from the crankcase. This MCS gear is sold individually and replaces OEM 26320-36 and 901329. Precision manufacturing ensures it meshes perfectly with the idle gear, providing the reliable oil return flow these classic engines demand to prevent internal pressure issues and oil carry-over.
