I think if it's that critical you should have a backup. Simply because you can't plan for a catastrophic failure of something and something will eventually fail. Of course it will be when you have plenty of free time available to dedicate to fixing the Cub. You could be down for several days, a week, or a couple weeks tearing down, acquiring parts, and reassembling.

First thing that comes to mind is the pulley should be a pressed fit in the first place. no bolt needed. second as mentioned check the crank for damage. third even if the key way was wobbled out a proper fitting pulley would not spin on the shaft. I am sure the pulley is shot. i would suggest getting a new aftermarket or used pulley. see how it fits the crank. if it slides on easy but snug I would use locktite bearing locker.But to do the repairs you will have to remove the front end of the tractor. If locktite doesnt hold then next step is to replace the crankshaft . then your getting into a expensive ordeal.

Might be a "long shot" but if your engine is good and you don't want to go into it, check with a machine shop and see if they can bore your pulley and install a bushing that they can size to fit the crankshaft.
This might be less expensive than replacing the crankshaft....just a thought. Stan

That's a real good idea. I may look into that.
