Can anybody tell me what affixes the cam to the motor for the ted's blade drive on a road show, the manual just shows the pic from the back of the motor and has a 6-32 screw listed but not visible in the diagram. Just got a repro cam to attach to the motor, there was no cam to begin with. I can see the cam has a flat inner side and the motor has a flat side on the metal extension but the cam opening is way to big to fit snugly over the motor.

Answering my own question here for future users, motor and gearbox 14-8016 for roadshow may come with the extended shaft of the motor untapped (with no threaded hole) if bought aftermarket. The motor I bought to fix my roadshow was untapped and when I emailed about it the pinball parts supplier said all the motors they had were unthreaded so it's that or nothing. So if you are purchasing a new one best to ask if it's threaded first. Currently I've got mine macguivered until I find a better solution.
