That long crank has threads on the one end for a pulley. I’ll bet that is the service motor crank
Steve,
Ken is still building a mini bike...and that would be cool, but a 122 will be better.
122 mower PTO will need the long shaft if it is 1" diameter x 2-3/4"-3" long (I forget the exact length needed) on the end missing from the other cranks.
