What are the differences between the c40 and c45 dynamos. I can find lots of parts and info for the 40 but very little for the 45

basically half an inch"

C40 is 4" diameter C45 4.5", I think the outputs are slightly different C40 22A, C45 25A

You can get 30A easily out of a C45 if the correct regulator is used. The windings are more substantial and its extra bulk allows more cooling. Straight fit too
