Write up or guide available for alternator pulley install?

I know some have told me i can just heat up the pulley, and use a aresol can to freeze the shaft and the new pulley will go on with ease? Others have recommended to take the alternator apart to press the pulley back on, i have access to a press but is there a write up on alternator disassembly or pulley install? Any tips? Things i should look for? Parts that need to be handled delicately? Thanks for any advice or links, im swapping out my steel Alt pulley for a march billet pulley, i really want to get it right without messing it up. I need to put the new pulley in exactly the same spot as the old pulley is now
