How interchangeable are the parts on the early rear wheel to the late rear wheel? I know the hub and sprocket is different. I know the threads on the dummy and long axles are different. What else is the same and what is different?

Here's the thing: I have a complete early wheel, including axles sprockets, brakes bits, etc. And a later rear wheel with hub and sprocket only. How much early wheel stuff can I migrate to the late wheel? The pathetic 1968-70 parts book is not helping one bit here. I know could just drop the early wheel in as is, but I would like to use the cush hub feature in the late wheel.

Can't you just compare the 68 rear wheel part numbers on page 28 to the 71 numbers here http://www.oldbritts.com/nor_comm_71_16.html ?

I could, but that is like comparing the two parts manuals. Which has its issues. The earlier manual is badly illustrated, and it is not easy to identify which part is the similar part in the later manual. Then there is the issue of number changes, which may or may not reflect an actual physical change. And the third issue is that even when the parts are different, that doesn't mean they aren't interchangeable. Example: if the dummy axle, long axle, and nut are changed as a set, even thought they are all different numbers early vs late, they still might work in concert with the later hub/sprocket.

In fact, that they is probabally the main question: Can I use the axles and the nut as a set from an early (1968) wheel in a late (1974) wheel?

I think T95 did this, you may want to PM him or search through his posts.

You can use all of the components within the brake backing plate for either type, that is backing plate shoes, spacer,lever etc.
The wheel bearings, hub bearing - where present - spacers, stub axle etc are specific to each model.

Sorry, I can't help!
I an curious myself on how interchangeable these pieces are. My guess is it unlikely considering three different dummy axels are available and then two styles of threads were used for the rear axel.

The same rear wheel spindle/axle part number was used from '68-'74 = 060289
The spindle/axle nut had the same part number '68-'74 = 060292

I make it two dummy axles?
060291= Fixed drum
062067 = Cush drum

There is a third dummy axle and another axle/spindle however they are for the 850 Mk3 disc brake rear wheel.

I would go with Dave M on this one as I am betting he has worked on both. I know that when Swooshdave was putting his rear hub together he had a dummy axel that would not fit properly in his 72 hub. The spacing was different.
