Heh, thanks for the replies guys. My intention was never to save the shaft and pulleys, only to gain access to the bottom of the crankshaft where I'll slide a single pulley onto it.
I would try the hanging trick but I have a bad feeling with the way my luck goes I'll either have to heat it or cut it. If I heat it I need to be sure not to overheat the crankshaft. Cutting, be sure not to cut into it. Either way I'm in for a ton of fun. lol
