About This Product
This MCS rivet and dowel pin kit is essential for properly securing the rear sprocket on 1930 to early 1958 Big Twin models and 1957 to 1978 XL Sportsters equipped with mechanical brakes. When you are rebuilding a vintage wheel and drum assembly, using the correct hardware is vital for safety and drivetrain longevity. This kit is sold as a set and includes the necessary components to replace OEM 8486 and 507045. It ensures a tight, secure bond between the sprocket and the drum, which is critical for handling the torque of these classic V-twins. It is a must-have for any mechanic performing a period-correct rear end overhaul.
Manufacturer part number: 507045.
