A great walk through, thank you!
Superb explanation. Many thanks.
Really enjoyed that. good job
Surprised that the shouldered dynamo is fitted to a 1969 traveller, I thought they did away with them mid 60’s so it is worth keeping it as they are getting quite rare now - I have a few for my Austins but when U/S they used to chuck on a replacement unit as the cost of a refurb was near the cost of a new one. Also a trip to the local Lucas service centre was often a test of your patience! Please keep up the good work - the Lucas service guides are excellent I guess you have some of those?
You covered many good points. I think that if you wanted this to last, and to not immediately burn the brushes/commutator, the commutator should have been turned flat to eliminate the ridges and rough surface (about 8:15). At 9:30 they are still visible. The brushes should also be "bedded in" before asking them to carry full current. See the "Lucas Manual A6" for great instructions. Did you check the front bearing for play and/or roughness? The original bearing has no seals, but a replacement is a VERY standard 6202-2RS (15x35x11mm thick) double-sealed - widely available and inexpensive. My C40 is on my 1957 Alfa Romeo Spider - like you, still having fun at our ages!
Ahh , so that's how you hold the brushes back when replacing the end back onto the comb
