Hey Kraig. I have been a machinist for 15yrs. What I have done in the past is wire welded the pto crank shaft end with a brass key in the keyway that way you won't weld the key way in and after removing the bass key and some file work you are all set to go. It is helpful if the shaft is out of engine with the bearings removed to prevent ball bearings arcing agaist the races. The crankshaft I welded 4yrs ago is still hard at work with no problems. Your pulley can be resloted at a machine shop with no problem. Hope this helps.
