Thanks to Ralf Brinkmann for sending me this information for an alternative adapter to the Teo Lamers crankshaft adapter. In contrast to the Teo Lamers adapter, you are able to turn the crankshaft by a 26 mm wrench.
Thanks to Charlie Mullendore of Antietam Classic Cycle for providing me with these photos of the Teo Lamers crankshaft adapter. This adapter fits on the tapered crankshaft of later Tonti models that came originally equipped with Bosch or Saprisa alternators. With the adapter in place, the pulley may be fit to operate the generator.
Crankshaft pulley adapter for using later crankshafts.
