"I started slow and then went a little harder until I heard a couple of the magnets drop out". \\ As you can see, two of the magnets broke and then fell out. The surface of the magnet that was glued stayed in contact with the rotor. \\ Actually the two broken magnets shattered. They're ceramic and will break like glass.((Vanmor of the XLFORUM http://xlforum.net/forums/showthread.php?t=1666986&highlight=stator+repair)) |

| - | * A torch (propane or whatever) should work better and faster. However, don't get it too hot or the magnet and the properties thereof could be ruined. Use a big screwdriver or small pry bar to LIGHTLY PRY the magnets loose or you will break them. TAKE YOUR TIME !!!
