About This Product
This Woodruff key is a small but essential component for securing the clutch hub on your drivetrain. It is designed specifically for Late 1985 to 1989 5-speed Big Twin models. Over time, these keys can shear or wear, leading to unwanted play in the clutch assembly. This MCS replacement matches the specifications of OEM 37523-85, providing a precise fit into the shaft keyway to ensure your clutch hub stays locked in position. To make sure you have spares on hand for the workshop or future builds, these are sold as a set of 10. It is a simple, cost-effective way to maintain the mechanical integrity of your Harley's primary drive.
Manufacturer part number: 901385.
