Crankshaft pulley adapter for using later crankshafts

Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models

A good overview from Ralf:

With the adapter you are able to replace the original crankshafts of Loopframe engines by Tonti crankshafts designed for the Bosch alternator.

• Timing chain version: The Tonti pinion gear on the crankshaft has to be included also.
• Timing gear version: for fitting the original pinion gear it has to be machined according to the Tonti pinion gear for chain.

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.
