Never missing the opportunity to create problems for myself, I found a clean vintage Snowmobile motor in great shape. It is a JLO/Rockwell 2F440-4 Fanner (440 engine of roughly 40 HP, 5 ports 2 stroke). I am messaging it into shape in hopes of using it on an off road kart that I currently have a Honda 200 motorcycle engine on it (shifting is a pain on trails).
Unfortunately, as is common when buying engines, it has a solid primary or drive clutch, but it is missing the Driven or secondary clutch. Finding info on it is difficult, but appears to be a Salsbury clutch made in LA, CA (think was bought by Comet some time ago). It looks totally different from other clutchs out there, but found a picture on an old high performance John Deere sled. It is believed to be a Salsbury 850, but don't know. I have attached a picture.
So, big question. I would believe that a suitable Driven clutch could be found if it is rated for the power and has the same side angles for a belt (believed to be 75 degrees). I know the spacing may require some trial and error, but I think I can do it. I would imagine most Driven units on most older 440 engines and perhaps even smaller newer units could handle the power. Replacing the clutch I have is possible, but fittment of a different clutch could be an issue, and they can get spendy. Thoughts are welcome.
Regards,
Russ
