This PTO is ON THERE! I've tried the the 2x4 with downward pressure, a gear/pulley puller (started to look like it was going to mis-shape the pulley). I'm sort of stuck. I was thinking of using a bearing separator - hoping that the more dispersion of effort might do the trick. Have you guys ever tried using a bearing separator (Problem is that I don't own one and if I can't borrow one, the only place that I know that has a reasonable one is Harbor Freight - $50).
