Today's tasks (because I just couldn't fathom another day of rust-scrubbing) involved cleaning and repacking the front hub, which went quite well, and dismantling the rear hub just to see what was in there and how bad it was. I knew it would be pretty gummy and dirty because the 
rear wheel barely turns. I had no idea. The photo on top shows the relative positions of the major pieces before I wiped the worst of the gunk off (yes, I know it needs gunk to work, but 
this stuff was--and still is--pretty badly gummed-up). The middle photo shows a more exploded view of the components, and the third photo shows them with the worst of the old grease wiped off. Also, having never taken apart a single-speed hub before, I was surprised at the complexity of the mechanisms. I mean, it's nothing compared to a three-speed hub, which frankly scares the ever-loving crap out of me, but I wouldn't have thought that just a single-speed would have so many moving parts. I can't find any exploded diagrams of single-speed hubs, and the outside of this one is still too rusty to find a manufacturer's stamp. Does anyone know if there's a general guide or diagram to one-speed hubs out there on the interwebs? I'd like to know what all the little bits are called.
