CIM FR801-001 Finding Gear help?

[123boo]

I have a CIM FR801-001 motor. I picked it up from a my old first team that disbanded a long time ago. I am an EE so I don't know much about the mechanical drive train.

Basically, I want to put a gear on the motor shaft itself. I don't need a gearbox or anything like that, just to somehow get a gear onto the motor shaft. It's keyed and I don't know what to do with it.

Thanks, I'd appreciate any information or help would be great.
