JEFF - If your rebuilding the PTO, putting a new spring in at least, just use a small gear puller with the jaws held into the belt groove with a hose clamp or ???. The threaded bolt on the puller will bottom out thru the center button and pull the PTO off the crankshaft. If there's a setscrew or two still in the PTO it'll bring the pilot bearing & eccentric collar with it.
I dope everything on the PTO up with anti-sieze when I put it back on. That way in ten years it slides right off.
