Pulley specs

[Cali]

Hopefully a quick answer (before this ebay auction ends)
What's the inside diameter of the GSS pulley?
1 key or 2?

And this factory pulley is giving me some problems trying to take it off- before I damage something, is it standard or reverse thread on the retaining bolt?

[Michael]

When you say "inside diameter" do you mean the opening that fits onto the input shaft?

[Cali]

Exactly

[Michael]

I would think it's the same diameter as those used on any other SN supercharger. I can measure the input shaft diameter on my SN, but the pulley my blower came with is held in place by a taper-lock, not a thru-bolt (in other words, the pulley I have doesn't have an "inside diameter" in the usual way).

Here's some pics:





Oh, and I believe the input shaft only has one keyway not two.

Thanks for the input- since you actually gave some hope it was a single key, I rolled with it and bid on the pulley.

Won the auction ($33) for a pulley with a diameter to fit my application- still hoping someone tells me if this is a standard or reverse thread on the retaining bolt :)

The retaining bolt is a right hand thread - yes standard (not reversed) thread.

Thanks!! It's being a little stuborn and I REALLY didn't want to lean on it with an impact or breaker bar until I knew for sure.
