1925 Fan

Unknown

I have 2 setups to choose from. Wide pulley and fan pulley and the narrow kind. Regardless of which one I try, I can't get the fan pulley to align up with the crank. At best, moving the adjustable bracket, forwards ( half off the shaft) a belt would come down near the frt. edge of the timing case.

I could machine a new shaft but all the parts seem to be right. Any ideas as to what I may be doing wrong?

Thanks,

Dorien
