Interesting thread. I too have encountered motor fields (all 200 series) that needed rewinding, but always avoided doing so because of the re-staking of the field studs. It has been my experience that the alignment of the field and armature assemblies is quite critical. Getting it wrong usually means very poor running, if not outright rubbing of the armature on the field. I sincerely hope you have success in this, and would appreciate at least a final follow up message letting us know the outcome - thanks!

BTW, while you have it apart, check that bottom armature bearing for excessive play - because of the physical arrangement of the armature, bearing and worm, a 0.1mm bit of play in that bearing could turn into a 0.2mm bit of play between the worm and worm gear.
