My BD 713 plane has a very sick sounding bearing. It's the one on the end of the armature which seems to be held in place in the outer housing by a tooth belt drive cog. To get at the bearing, for which BD sell replacements, I need to remove the cog but can't see how. Is it a hub puller job or is the armature shaft threaded to accept the cog. Any advice please or pointers to where it exists?
