Alternator pulley removal

[flaatr at yahoo.com (Euroroc II)]

So how do you get this F___ing thing off!!!

If I had an impact wrench I think it would be cake but I don't. We tried to 
jam the old alternator with a screwdriver but could not remove the pulley 
bolt. The bigger problem is the new alternator I bought has a serpentine 
pulley and internal fan.... any suggestions on how to remove the bolt on 
these alternators would be very helpful.
