Got this flywheel/rotor puller from ebay (M30x1.0 R.H.) and tried to remove rotor. The rotor will not budge and I ended up stripping the fine 1mm threads on the puller. I think the no-name puller was of poor quality and I am going to try to get hold of a Motion Pro puller. Can someone give me some advise on how to effectively use the puller to get this flywheel off. I do not want to mess up the threads on the crank. Is there some type of permanant threadlock between the crank and the rotor, that is making this rotor so tough to remove? I tried to tap the totor and the shaft with brisk taps with a hammar, but no luck. Can someone advise on the best way to take off this rotor. I am loosing my confidence and may end up taking it to a shop to take off, if I do not have any luck with the Motion Pro puller (they warranty this for 1-year, so I am not worried about breaking it). Also, for information I did not remove the six hex screws in the rotor that attach a large gear that is turned by the starter gears. I have been told that the rotor and the clutch gear assembly (behind rotor) can be removed as one assembly.
