A title mistake at 12:19 - the cone was in fact loosened, not tightened. For any questions or comments, please use the BikeGremlin.Net forum: www.bikegremlin.net/ Relja
The Shimano manual recommends simply soaking the internal assembly in some special mineral oil for 90 seconds, letting it drip for a minute, then optionally applying some light grease on the pinions (satellite gears). This method doesn't require disassembling the internals. People who don't feel like spending so much on Shimano's fancy oil find that a standard 75W90 GL-4 MT-1 gear oil works well in practice.
These big hubs are phenomenal pieces of engineering. I used to have a Nexus 7 for a couple of years and loved it. Recently I've seen a few disassembled and service here on RU-vid and quite frankly it has really put me off them. I love the simplicity and ease of service of the Sturmey Archer 3 speeds, but their range is too limited. I really want something in between for casual city cycling, shopping, etc on a vintage upright bike. What do you think of the Sturmey Archer 5 speed? Many thanks. 👍
I haven't seen (not to mention serviced) a Sturmey Archer 5-speed hub (the 3-speed ones are quite durable). I believe that Dan Burkhart has forgotten more than I've ever known about geared hubs (to use that Serbian phrase). :) I'd ask him. His channel: www.youtube.com/@2wagondragon Relja
