If parts for your engine are lost, we'd not have any. The engine's been out of production long enough that parts specific to it are no longer available from us or O.S., in Japan.

The pump was a gear-type pump, and one of the gears was on a shaft and tied to the shaft with a very small steel ball. It worked similar to a Woodruff Key. We'd not have that part. In fact, we never did. Repairs to the pump and regulator system were performed only at the O.S. Factory. Also, once the supercharger had been disassembled, you needed to use a special sealing compound on the housing when it was closed to make sure it operated properly with no air leaks.

If you send an email to the address below, we'll be glad to see if we can locate an exploded diagram of the supercharger.
