About This Product

This starter shaft gear from MCS is a critical component for maintaining the starting system on belt-drive Big Twins. It is specifically engineered for models equipped with a secondary belt drive, including the 1982 Classic, 1982 to 1983 FLH, and 1980 to 1986 FXB and FXSB models. It also fits 1984 to 1986 FXWG and 1987 to 1988 Big Twin models with the secondary belt setup. Replacing a worn gear is essential to prevent starter engagement issues and potential damage to the primary drive. This part is a direct replacement for OEM 31340-80, ensuring a precise fit and reliable performance for your vintage drivetrain.

Manufacturer part number: 900785.
