All I have is assorted 3 jaw pullers, which I can see tearing it apart with. Actuallyyyyy, I just now thought of an idea that could work. I have some rod that I can cut up and place under the inner wheel and hook the 3 jaw to them.
if that doesn't work, how would an impact gun drive it off? seems all it would do is crank it on tighter. If I turned it the other way it just unscrews.
