OK. Everybody has said some people have fixed this. I DID. My pulley was toast and my bolt broke and the keyway was sheared on mine. Is there still somewhat of a slot in the shaft? if so the slot is to line up everything- The bolt actually holds it in place. My was really hard because when I did my t-belt I had used Locktight <img src="/forums/images/graemlins/zombie.gif" alt="" /> Now to removing it: I did use L handed bits and a small drill. I beat the crap out of my forearms trying to be careful. I ended up drilling the center out and basically had a thread tube <img src="/forums/images/graemlins/smile.gif" alt="" /> Then I made a pick out of an old allen wrench. I used this to work into and bend the edge of what was left in the hole. Once i had the edge bent, I took needle nose vice grips and unscrewed the "thread tube" out! Then I took a thread cleaner (kind of like a tap) And made sure threads were clean. The one thing I did not do was change the crank seal while I was there and now soon and am going to havta do this. I have around 10,000 miles on truck since this was a done. Hope this helps! BTW My truck has 267,000 miles on it. Bolt lasted pretty good LOL!
