Nankai No. 75 Coaster

[BackWoodCycle]

Anyone ever heard of these hubs? My instructor brought me one today to rebuild but I've never heard of it nor can I find any kind of diagram to do it. What he brought to me was the empty hub shell laced to the rim, and a box full of the internals sooo no clue how it went together. It's stamped "Nankai No. 75 Coaster" on the hub shell. Anyone have one they've rebuilt or one for reference? Any help would be much appreciated!!

Those look like nice hubs. This link has some diagrams of a later hub but it might be similar.

Pictures might help too.

hopefully this helps.

The discs of part 278 will be alternating silver, round disks and brass, three toothed discs

The hub shell will have a tapering side that gets smaller on the inside. That's your drive side.
