The 3" CIMs have more torque, but not more speed. In fact the larger CIMs are only have about 80% the power of the smaller CIMs. Bigger is not always better.

That said, anything is possible.

We looked at mating the 3" CIM to the 56mm banebot transmissions, but decided to solve our problems in a different way.

This what we found out.

The shaft diameter and length appears to be correct.
The shaft should be keyed.
We removed the long bolt from last years 3" CIM so that we would have two long bolts to make it easier to mount.
The mounting plate on the transmission would have to be modified to accept the bolts from the CIM.

Keep in mind that we did not actually make make the necessary modifications, so I am not sure other problems might come up.
