peetee, you have an early (captive cotter) clutch, but it has at least one grubscrew as well. If it has a second grubscrew directly over the keyway, it would probably work as well as the later style clutch that had two setscrews (one where yours is, and one over the keyway). Does yours have a second grubscrew, and do you know how it came to have it or them?
