918233 Coupling, starter shaft to starter gear

This starter shaft to starter gear coupling is a critical component for ensuring reliable engagement every time you hit the start button. Manufactured by MCS to meet or exceed factory specifications, it is designed specifically for 1990 to 1993 Big Twin models. When your starter motor is spinning but the engine isn't turning over, a worn or damaged coupling is often the culprit. This part replaces OEM number 60647-90 and provides a precise fit to restore proper starting function. It is a straightforward replacement for any mechanic working on early nineties Evolution-era machines, ensuring the torque from the starter motor is efficiently transferred to the primary drive system.
