-Whether you have removed all of the magnets from the rotor or are just replacing some, the magnets need to be balanced around the rotor. The template shown is made with the assumption that all the magnets have been removed but will work (on unaltered stock configurations) while replacing 1 or a few magnets. ​ +Whether you have removed all of the magnets from the rotor or are just replacing some, the magnets need to be balanced around the rotor.

 +  * Let it sit a few hours and then pull the cardboard out (making sure it doesn'​t get stuck in the glue).
 +  * To beef up the magnets, let the whole cluster reinforce itself by way of epoxy bridges between the individual magnets. ((CharlieB of the XLFORUM http://​xlforum.net/​forums/​showthread.php?​t=900913&​highlight=stator+rotor&​page=3))
 +  * It would be hard to fill it all with the JB, for one because it has steel in it and gets pulled by the magnets. This helps pull it into seams, but if you put too much in it will pull over the magnet onto the inner diameter of them. You will then have to sand it off to keep from interfering with the stator windings. ​ Since the steel in the JB Weld will pull towards the magnet, it's not a good filler between the magnets.
