Auto pilot gear bolt


Bob Ross
 

Good day,

On a 2002 SM2K in the autopilot area above the galley sink I think this smaller gear should have a  key retaining bolt or similar in the middle of the shaft.
Having never seen it I am not sure what it looks like nor its dimensions.
Can anyone share a picture of it or any size data?

User question: is this a correct way to share a photo or is there another  preferred way?
Thanks
Bob
