how do you change an alternator pulley?

Im installing a 200 amp alt, and im trying to change to pulley to a smaller one.. But the stock pulley does not seem like it wants to come off. Im using a belt wrench and a breaker bar but the nut will not budge. So i was wondering if there is a technique, or a special tool to do this.

Most of them are on there good. If you have access to a good impact gun, use it while holding the pulley and it should come right off. If not check with your local auto parts stores, most of them, if they have the tools, will do it for no charge or a small fee.

gear puller will do the job, or a local machine shop or alt shop...

An impact gun will work just fine.
