If you dont want to bring the heat, bring the ice! Get some of that freeze off, or cheaper, some dust off and invert the can while you spray the snout down. The white stuff coming out is liquid CFC (freon type stuff) and is some cold stuff. get as much on the snout as possible before your hand freezes to the can, and then use slide hammer or way better, a 3 bolt puller on the pulley bolt holes. Act against either the old bolt or use the cone adapter and center it in the crank bolt hole. And that damper is done after hitting it with a hammer. Thieves use the same stuff to freeze "The Club" theft deterent steering wheel locks, and then whack them with a hammer to shatter them !
