[ex 2 Base]

If you are not going to use the gear again, you might be able to careful grind it off, first using an angle grinder then using a Dremmel. When did it, I poked the gear and end of the armature through a piece of rag to keep out any particles getting into the windings then ground away.Once the gear is hot a small screw might prise it off. I have done this in the past without damaging the windings.Ted
