You can also buy the hub and pulleys from tractor supply company also. You buy hubs with different hole sizes and them the pulleys come in different sizes which you weld together. You would still need a key but the new pullys use 2 set screws. To take the crankshaft to a machine shop you would have to disassemble the engine. This would also give you a good way to go through the engine for a overhaul.
You said (Got them both off and the new shaft is thicker.) so I don't under stand the last post? Are you not saying the crankshaft is thicker? or am I missing something.

Well, I may have spoken out of turn. It's bigger *now* but I think it's because of the sleeve that is over the part of the crank that hangs out the bottom of the motor, which the pulleys are on. So, I think if I can get that nut off the bottom, the sleeve will come off, leaving the smaller crankshaft behind. If that makes any sense. lol

OK I understand now. The crankshaft sizes may well be the same then. let us know how you make out with it.

Ok, so I got the bolt and washer off of the bottom. That's what held this 'sleeve' onto the bottom of the crankshaft. Now, I can't get the dang thing to slip off. I'm sure it's rusted, used a gear puller to no avail. I'm assuming when it does work it'll seperate at the area with the arrows? Any suggestions on how to bang this thing off?
