Series 2 cnc 2 hp motor on a series 1 bridgeport?

[CATCH22]

Does anyone know if a bridgeport series 2 cnc 2 hp motor will fit a series 1 variable speed bridgeport mill.

Thanks Mike

The shaft diameter is different on the 2hp motors than on the 1-1/2 motors. I think the varidisk setup is slightly different also. I would avoid getting the motor with hopes of replacing a non-cnc machine motor.
