This part does not seem to be my problem the only thing I have left on the shaft is the copper coil the fan and whatever the part above the fan it spins freely around and it seems to be set on a device that allows it to tilt. I am struggling with this, please point me in the right direction of the removal of the copper core coil.... There has got to be an easier way to remove this.

The article does not mention why an armature needs to be replaced. So why is it necessary to replace an armature? If there is no obviously visible problem, what could be wrong with it?
