a little progress
Pulled the clutch hub/ rotor last night found exactly the scenario I've been reading about. Magnets had let loose & destroyed the stator in the process. You can see the shield over the magnets of the new rotor, hopefully eliminating this problem for ever. There is a big difference in the strength of the magnets however. The magnets on the new rotor are much weaker than the ones on the old factory part. Hopefully that won't be a problem.
