1936 Generator Pulley Alignment

[Timstruck]

I have a bit of a mystery that I'm trying to figure out and was hoping someone here could steer me straight.


I purchased a generator for my '36 and when I went to mount it, the pulley is about 3/8's of an inch too far to the rear. This is the pulley that a fan attaches to. I bought a generator that has been converted to 12V.


I do have an aftermarket intake (Offenhauser) so I measured the distance from the front bolt hole to the generator mounting flange. I compared this to a stock intake which I also have and the Offenhauser flange is actually a quarter inch forward of where the stock unit is. That means if I went back to stock, I would be even further to the rear! I am wondering if I have the wrong generator or perhaps the wrong pulley. My generator has a 5/8's diameter shaft and I did read that this may not be stock for my '36.


Is it possible to shim the pulley forward? I can't picture a way to shim the whole unit forward because the generator mount fits in a slot.


Ideas?
