The design took some time to get right. The basic design idea came from Ross Cunniff. Below is a profile view of the spacing involved.
The face of the motor had no mounting holes, and it was not flat.
After machining the face flat, the material was not thick enough to support threaded holes, so the spacing collar was bolted to the motor face from the inside.
The coupling uses a taper-lock design that squeezes onto the splined shaft of the motor. This allows adjustments to the position of the flywheel and clutch on the transmission input shaft, though it means pulling the motor to access the screws. Good measurements allowed me to get it right the first time.
The motor is suspended from a bridge which is bolted to the original motor mounts on the frame. The shop machined slots in the bridge and the motor's mounting plate to adjust the exact mounting position of the motor.
