I took an 18 inch 1" X1/8" piece of steel I had laying around. I welded a bolt through at the end closer to one side. I place the bolt through one of the 4 holes in the pulley and use a wrench on the clutch fan hex. While turning the hex in the direction to remove the fan the flat stock will brace against the hex enough allowing you to break it free, once loose I remove the flat bar and you can remove it the rest of the way because the belt will hold the pulley enough for removal.

Worked for me anyway.
