What exactly does one do with a working Shimano Nexus 8 speed hub with a broken flange? I can’t answer for everyone, but at Trophy, we take it apart and see what makes it tick (or shift in this case). Since Shimano doesn’t provide service kits/spare parts/diagrams and they don’t recommend taking their Internally geared hubs apart for repair, we were flying blind and had to slow turn lock nuts, pry snap rings, and use a magnet to catch rogue roller bearings. But man, was it worth it! The inside of this hub was really amazing to look at and fiddle with. There are far more parts involved than in the many Sturmey Archer hubs we’ve had apart so we took plenty of pictures along the way to make sure we could remember how it goes back together. We have no plans of rebuilding this particular hub, but we did separate, catalog and bag all of the parts so that we can do black market repairs on Nexus 8 Speed hubs in the future… don’t tell Shimano though, it’ll probably void the warranty! Anyway, here are some of the pictures for those of you who nerd out like us about the moving parts inside of the machines that keep us rolling and never get credit!
