So from the drawing I clearly have part 12 however it has a big hex on the end and it appears to be one part, see photo. I think 15 is for a starting handle which is not there. Would a big bolt be an alternative? If so I presume it extends to the crankshaft. If the possible bolt and the fan extension cone as 'welded/rusted' together will they come of together or will a woodruff prevent that?
