My Stuart has a dynamo driven of the engine via a shaft coupling, looks like the unit needs a rebuild or a new one, does anyone have a suggestion for doing this?
It's not 'handy' for you, but "Dingbro" in Inverness do starter motor and alternator repairs. I'd imagine that close to you would be a similar facility.

You have a Lucas CA45 dynamo mounted on a saddle, no pulley simply two steel peg drives with with rubber spider coupling in between is that correct?
Your Lucas dynamo is simple as a wheelbarrow to overhaul, does not need a specialist. Once you have the unit off the engine undo the grub screw which secures the peg drive to the shaft, at the other end there are two slotted screws which hold the whole unit together, undo them and pull the ends off the body. You end up with front plate, back plate with brushes attached, armature and the body with stator winding's still attached to the back plate.
Clean up armature with some emery, undercut the segments with hacksaw blade slightly, new brushes and bang it all back together, 20 minute job at best...............
