Hi yall, im new to the forum not sure if im posting in the right area but:
I have a 2004 sos sc s2000. The belt was a little frayed on the supercharger belt and I should have replaced it early but I didnt. The belt caught on something, tore up the liner of the hood and just caused havoc. Everything seems good now except for one thing. The hardware for the pulley is gone completely, its nowhere to be found and Ive moved since then.
Basically the pulley was just spinning on the shaft no key and no bolt holding it in. In fact I didnt even realize until now when I was replacing the belt.
Here is the pulley spec and what I can reason.
Its a science of speed 3.4" novi 1200 supercharger pulley. hardware lost:
1. The bolt that attached
2. The washer that sat on the bolt
and whats gonna cause me some trouble
3. the "woodruff" metal key that engages the shaft with the pulley. This I measured the hole, its .5 cm wide, 4 cm long, and harder to measure but approx .75 cm tall and its U shaped.

If anyone is of any help this would be so much appreciated and I emailed SOS but they havent responded, they might be on holiday or something.

 

I think there is some confusion. The parts you're missing all seem to be standard Honda parts.

The SOS pulley mounts to the stock honda pulley with a ring of like 10 or 12 small bolts. Bolts into outer ring of stock pulley.

Stock pulley is attached to crank with the stock large bolt, washer, and key. These should all be available from Honda (guessing they're common to many other Hondas).

So outer pulley, SOS, drives sc only. Attached to main pulley w ring of small bolts (which sound like they are all still in place). Main pulley, stock Honda, drives all stock accessories using stock belt.

So SOS crank pulley gets power from outer ring of stock pulley, which is attached to main pulley hub by a rubber ring. Then main pulley hub (stock Honda) is attached to crank with bolt, washer, key.

So sc driven by crank, to key, to rubber ring, to sc crank pulley, to belt, to sc pulley.
