520H catastrophic stator failure

Recommended Posts

Flywheel was second-hand, seemed to be functional. Stator and magnets destroyed, but how? If glued-on magnets came unglued, why didn't their magnetism hold them in place? Is centripetal force greater than magnetic force? Is it possible some lost screw or nut found its way to the magnet ring, and started the destruction? Rectifier also not showing any dc voltage with new stator. Crankshaft endlay as measured from flywheel to governor housing seems to be .001", within specs.
