ricksrj58 273 #1 Posted March 22, 2010 Does anybody know if you can get a pulley for a tapered shaft? The end of the shaft does is threaded for a bolt and there is a keyway. :omg: Share this post Link to post Share on other sites
sorekiwi 761 #2 Posted March 23, 2010 I dont know of a source for a pulley to suit a tapered shaft, but I would think it would be possible to machine one (providing of course that you have a pulley with enough meat in the boss area to accomodate the large end of the taper). You would have to find a machinist to do it. He would probably set up the lathe to cut the correct taper off your shaft, then bore the taper with a boring bar. It would also be a little tricky to determine the final position of the pulley. The keyway would be a little labor intensive too, most broaching equipment is set up for a straight bore, so he would probably have to make a tapered bush to guide the broach. I dont think you'd want to be paying someone machineshop rates for all this... For what its worth there are a lot of gears and pulleys in vintage Rolls Royce engines that fit on tapers with keyways, and there have been quite a few racing engines over the years that had cam pulleys running on tapers with no keyways. And of course there are a lot of flywheels mounted on tapers too. Share this post Link to post Share on other sites
ricksrj58 273 #3 Posted March 23, 2010 well my father is a tool and die/machinist and said he could make one,but he is allready making new tranny parts for my rj58 and my springfield tranny so if i could buy one that would be one less thing for him to make,he is already at 14 parts to make lol Share this post Link to post Share on other sites
Kelly 1,033 #4 Posted March 23, 2010 Might be just as easy to swap cranks. and cheaper. Share this post Link to post Share on other sites
Roger from southern Iowa 1 #5 Posted March 23, 2010 It would be a lot more simple to replace the crank. Share this post Link to post Share on other sites
