Hi Group I have a B&C SD20S alternator on the vacuum pad of a 914. Speed is not
ideal for the SD20S, a bit too slow.

I'm looking at the parts diagram and there is a 29T vacuum pad drive gear that's
driven off of a spline on the dog hub. It drives a 22T driven gear that engages
to the vacuum pad drive sleeve.

>From the pictures it looks possible to have a larger than 29T drive gear and

than 22T driven gear.

Does anyone offers such a set of gears? Thx. Ron P.
