Looking for 1970 bus generator parts.

Sounds like you need 38A generator tin?

The 38A generator pully is a square D style. I have had difficulties finding them...

Yes that is correct.

What does square D style mean?

The hole in the pulley where the shaft goes thru. The shape of the hole looks like a square D.

Unlike the standard 30A generator pulley hole. The standard pulley just relies on the two different size tabs to keep the outer half locked to the inner half.

The 38A pulley also uses the hole to lock itself to the shaft.

Here are 2 pics of a 38A square D pulley:

This looks like a stock bug pulley.

This looks cast, like the one that goes closest to the pulley on the GL17X generator. From what etka says, maybe the "outside" half of the pulley from the bug would work with this. ETKA only gives different part numbers for the inner.........

You wouldn't want to part with that cast one would you?

That is the same pulley in both pics. They came with the 38A generator.

I may have one or two complete 38A generators w/all the tin here. It has been
