S&S Cycle offers oil pump driveshaft woodruff keys for a wide range of Harley-Davidson© street bikes from 1936 through 2000. The semi-circular shaped machine keys fit into a specially cut slot (called a keyway) on a shaft, preventing gears, hubs, or other components from rotating independently on that shaft. They essentially act as a locking mechanism to keep parts aligned and prevent slippage during rotation. These steel replacements are machined according to factory specs to ensure proper fitment and performance. The keys are available individually or in a set of 10.
