I am sure that there are 1 or 2 tricks out there for removing a fan that seems mated to the alternator shaft/keyway that I have not tried. I've always been able to use elbow grease plus "soak overnight in penetrant" but this time I seem to have met my match. I'm obviously looking for quick options short of removing the shroud, etc. Is there a tool solution, process, folklore, legend, myth........
