I pulled the outer ring off like instructed, and now the hub plate will not slide over the backside of the hub. I figured it would easily fit over the backside of the hub but it does not. Perhaps the coating is getting in the way of it?? I'm not going to hammer it on there... I noticed the front section of the shank where the ring goes on is smaller in diameter than the rear... What gives? I don't want to damage the hub or tool.
