I used the CIM motor with a 14 tooth gear to mesh with the gear train. This year’s motor was used in the dual speed transmission so I bolted on the 2002 CIM (Atwood, Chiapua, see text on motor in picture). Several people at Riverrage commented on my ‘magic’ gear mesh with this demo.
The circular marks on the main plate are the result of chain stretch, chains falling off and chain wrapping around the sprockets. Carefull atention to chain tensioners during break-in could have avoided this, but what the heck, we just keep driving until they need tensioners!
