The best way to get a viscous hub off is to use a hammer and prybar, with the fanbelt still in place holding the pulley tight, locate the prybar on of the central BIG nut's flats, and give it a whack. If you get it right the nut will undo and you'll be able to spin the hub off with your fingers. It can even be tightened the same way.
there is plenty of room do the belt with the rad and slam panel in place.
