I need to remove the pulley from my alt, in order to install a March serpentine pulley.

First, how in the heck do you get it off?? I have a two arm puller, and it would not move at all, even after heating the pulley a bit. (carefully)

Second, if I ever get it off, how do I go about putting the billet pulley on without damaging it? Put it in boiling water for a while and then gently tap it on?

Need some guidance here guys. I called a local auto electric place here, that rebuilds starters and alternators, and they don't have a puller .
