Roger,

1. Yes, the previous shop installed a 3.5" crank pulley and the Rayloc 13-8283 came with a 67 mm pulley.

2. Before: Crank pulley 3.5" alternator pulley 67 mm
After: Crank pulley 5.0" alternator pulley 67 mm

3. The actual diameter of the alternator is larger but it is referred to as a 93 mm alternator, probably that is the diameter of the internal rotor.

Thanks for the clarification, Don. As has been stated before, I cannot imagine any reputable shop installing a 3.5" crank pulley! It simply does not make sense.

Based on the other mods they did on Don's engine, I can totally imagine THIS shop doing it. What a clusterbleep.
