You must not only use the correct tool, you must use the tool correctly. You do not install it, then keep turning until something moves. What you do is install it, with the center nut on fully thread engaged, but not tight, and put some tension on it. If you don't seem to be getting any response, you do not keep twisting until something happens. You stand aside, ring on the outer edges of the drum with a hammer--you are setting up vibrations, not trying to beat it off--then walk away. Come back in an hour or so, and add a little more tension, then ring on it some more. Something like LIquid Wrench or WD-40 on the spline is a great idea. You let tension and time do the job, not brute force.
