r26 hub
From both the parts book and the pictures you can see the top-hat spacer on the drive/brake side and the reverse top-hat clearly missing from the hub side. If you look in the picture of the hub side you will see the sleeve, wedding ring insert and the bearing, but no top-hat spacer. Also its clear that the felt seal surface is not sealed on the hub side. It has been a while since I did the R27, but I do seem to remember the "reverse top-hat" on one side.
Oh, and I do believe that the "hub cap" gets bolted on first, then the reverse top-hat, and then small hublet (my term). This allows the small hublet to stay stationary with the axle while the larger hub turns. If I remember it all correctly....
Hope this helps.

Part 14
Huggett is the only diagram that shows both thrust sleeves, also suggesting a quantity of 2 (two) in the order list.

So, what is it, two or only one thrust sleeves?

I purchase 2 of the largest shims available and will use the lathe to size them.

Your $.02 and a few hundred more
Slash2 wrote these lines 09/26/2016. I can not call the work I've done on Zenaida a full restoration.
For you what is a a full frame restoration, what would you call a restoration and what is a re-paints cleaning and replacement of parts?
Engine, gear box and final drive were repaired 1500 miles ago. I only cleaned the exterior a little. I know mechanically everything is on spec and in perfect working condition.
As I mentioned before, Zenaida had a very hard life. Since parts were impossible and during a period illegal to import into Mexico, it was patch with anything at hand to make it run. Perry Bushong (q.e.p.d.) found VW parts and water damage inside the engine; we concluded it was submerged at half engine hight for some time.
In my case since the frame was broken and the fenders had metal fatigue cracks it became necessary to strip the paint, weld and repaint.
This says a lot of old German machinery, if serviced and maintained they will last forever.
I invested time and money repairing it because Zenaida is my favorite bike.

Bearings
After a nice and month-long vacation in the Antilles the hub ball bearings arrive yesterday.
Some one in 123bearings confused San Martin with San Antonio.
I will start the lacing wheels shortly.
