I'm currently rebuilding a MC 101 with the 3/4 crank. When I got into this one i noticed on the PTO side the bearing inner race is twice as wide as the bearing and the seal rode on this race instead of the crank. Not what you would expect to see and there is no number on the bearing. Is there a replacement bearing or do I need to use a different seal and a different bearing?

Sounds like you have the correct bearing and seal. I don't have the part numbers to offer you.
If you switch to a tapered shaft crank then you would use the standard bearing and seal.
I have an NOS tapered end replacement crank for your motor listed on ebay now. If you buy the crank I can also supply you with the bearing and seal you need to make the conversion. It's hard to find a decent clutch that fits the 3/4" straight shaft cranks. If you replace it with the tapered version you can use any of the common clutches.
