Sorry Sod, no part numbers... :( This came out of a book from 1976 called "BICYCLE MOTOCROSS" by Jack Scagnetti

When you guys rebuild these, what do you use inside the hub body and brake shoes? Oil,grease?

I also could have used that schematic. Instead I took a crap load of photos as I disassembled it. Will search through my archives, and if I have the photos, I will post them. Did the same for a motomag bendix hub.

Coaster brake hubs will drive you (me, that is) bat shit.

Brian, I also might have a donor hub cleaned and in pieces in a tupperware. If you want it, let me know.

Yes, I do still have it.

I know for a fact that they don't work as expected if you have parts left over after you've reassembled the hub... That little washer #11 turns out to be prettttty important when you're going downhill on 36 lbs. of bike and need to slow down!

richard, so what you're saying is TWO extra parts might be twice as bad as one extra part?

I have a bunch of NOS Shimano parts if needed. Pretty much all the internals.

Sure I'll take it if you want to pass it on. Coaster brakes are not that hard (for me anyway.) but I have learned a few tricks on them over time. I'll put those parts to use.

Interesting that this pic is in a 1976 published book. Means that this hub was available in 76?
