This one sorry, I need another one and I can’t find it in AmazonThe chain has fallen off of the sprockets. The belt is running from the clutch to a drive pully. The shaft between the sprocket and the pully is called a jack shaft. I assume you know what the tire is. Hope that covers it all.
Good luck trying to find 1. I had to take mine apart an had a machine shop specifically make mine.This one sorry, I need another one and I can’t find it in Amazon
