Ray have you removed the two locking tabs in the threaded portion behind the rear rim of the fan pulley? If so and it still doesn't turn, get a screwdriver and gently lift in the slot where the two tabs are, to relieve the binding pressure on the rim so that it can be turned. Spray plenty of penetrating fluid on those threads and work the rear rim to and fro relative to the front rim to loosen it up.
I'm planning to remove my radiator next week with the #44 attached as I just bolted it up and now need to change out a gasket behind the front accessory drive cover.
I took the two bolt out and the retainer out and been soaking for about two weeks. I took the fan blades of and the bully and the bearing seem to lock up that I can't turn it?
Ray, here's the split in the rear hub I mentioned. If the retaining bolt had been tightened really tight, that split might not be releasing fully. Carefully insert a screwdriver and pry it open a little - not too much to break it. Do both splits, 180 degrees apart. Then check that there aren't burrs on the edge of the retaining lock slots in the front / threaded hub. There's nothing else that should be preventing it from turning other than damaged threads.
