I was wondering if the guts from Bendix blue band hub can be put in the shell of a red or yellow band. I think a 36H hub with an overdrive gear would be great.

I don't know, I'm just posting to see the answer if you get one. 
Here are the parts diagrams from the trfindley webpage.
You could compare the yellow 2 speed auto to the blue overdrive, they look very similar. It shows a box in the diagram of parts not compatible with yellow band, but doesn't say if it will mount up in the same hubshell.
A 52 (or bigger) chain wheel might give the same effect as overdrive using a yellowband hub.

Thanks for the info! Now to find the parts I'll need. Once I have some money to spare.
Please let us know how it turns out.
I tore down a blue and red band tonight, ill take apart a yellow tomorrow and take some pics of everything and see if I can get the blue guts in the yellow hub. Im not gonna lace it up to a wheel, but ill see if it functions in my hand like it should
YES! You can throw yellow band guts into a blue band hub! B607 was correct, the diagram is wrong. From top down with entrails out, Red hub, blue hub, yellow hub. 4th pic is of all the parts that will work in all 3, the last pic is of the yellow and blue parts that will interchange. Note that I forgot to put the indexing spring and ball bearings in the "works in all 3 hubs" pic......Sorry, I am burned out on pics and hubs...but thats the story....

The chart that says they won't interchange says so for cosmetic reasons, not mechanical. They didn't want the blue and yellow shells to get mixed up, but the dimensions are the same. So now that you have a green band, (blue X yellow make green) tell us how it rides. Gary
Awesome! The pics were informative. I'll save this for future reference.
Don't know these specifically, but having worked in manufacturing, I strongly suspect they're the same as there isn't a reason to use a different bearing as it incurs more expense and reduces line flexibility to do otherwise with no apparent value. The more parts that interchange, the better, and that's just assembly, never mind in-house manufacturing/outsourcing, stocking, potential quality problems due to mix up, etc. I often (and sadly) amuse myself by noticing parts interchangeability between a company's models as, to me, the higher the number, the more it indicates how smart the company is. It also leaves more room to be able to charge less than competitors, make more profits, or spend the money in better places.

I have used yellow band guts inside a 28 hole Blueband hub to get the lower gearing on a 70's Stingray . The only difference in the hub is the color ,but the guts of a blue is overdrive and the yellow is under drive like the red band . The Red Band will NOT interchange with either one.
Dave, you've got the skills of a surgeon and the patience of Job......thanks for solving that colorful mystery for your RRB family members!
