Hey, i just went through this myself. After the pulleys set screw(s) are removed... you might need a puller like the one in this link:

If you have any mechanic type buddies they'll probably have one you can barrow. If not, you could probably buy or rent one pretty inexpensively.

ps:
you might find you need to screw the correct size bolt fully into the end of your crank, so the puller doesn't damage the internal threads.

if you dont want a puller you could hit it with an air hammer while using a pry bar or you could use a hammer and punch thing but that would require 2 people...

i suggest starting up the engine, and rubbing a piece of sandpaper on the crank while its going to get the rust off. Then you will need a 3 jaw wheel puller to get the thing off, if all else fails head up the pulley with a torch.

I just pulled one with a 3-jaw puller after sanding and lubing the crank shaft. It still took a lot of effort to get it off and the old pulley was destroyed in the process (it was a thinner, stamped metal type rather than a casting).

I ended up getting out the impact wrench to attach to the puller.

I had one that WOULD NOT come off with even a puller. I cut it in half with my sawzall. No harm to crank, but i used up 3 blades (cast iron, 4 inch think dual pulley)
