Main Shaft Outer Bearing Supports

Main Shaft Outer Bearing Supports

The transmission support is mandatory for all 1965–up 4-speed transmissions in combination with open belt drives or tin primaries, because the mainshaft of these transmissions has an additional support in the aluminum primary housing. If the housing has been removed, a supplementary transmission support is required.

The bearing supports are designed for Big Twin 4 speed transmissions 1970-1984. The bolt distances on 1965-1969 transmissions are identic, but the support plates will fit only after extensive milling. Due to the shorter mainshaft a 1965-1969 clutch is placed 1/2” closer to the transmission case than the 1970→ versions.
