Zubzub - I take it you're not a saver, but I would think that at least the drive gear set and the end-housing should be saved. That's probably the "gold" anyway, and wouldn't take much room. Although the gear wear does look as if it has been run with poor tooth contact.
Anybody ever seen the Leece Neville gear-drive alternators that used this end housing as an adapter?
Are there any pictures of the Zubzub belt-drive conversion posted?
