Hope those bearings are original quality,I once had some for my LR swivel hubs from britpart,poor,they were narrower than the originals,sent those back.
Have you been on to the owners club Shox ? There is normally a lad who specialises in these finiky jobs, maybe able to give you a few pointers ?
Are you sure that the 3 thou TIR isn't deliberate to allow adjustment of the worm drive engagement?.
They look like "angular contact" bearings, although the description I read on a bearing supplier website calls them "light deep groove".
If the bearings are installed as a pair (as angular contact bearings generally are), they are usually fitted either with the two thick edges of the outer race mated together, or the two thick sides of the inner races mated together.
Sometimes, depending on what "float" is necessary, there may be a shim fitted between the inner races.
I should imagine so. The Progress drill has a quill nose bearing that has a split outer, so it's effectively two bearings set up in just that way.

Is there an image showing the parts' relationship to each other?
That was my thinking too, does the drawing not indicate the same?Is item 39 is splined to the worm centre? It looks like the outer race sits in the worm gear, one each side. If you assemble it your way, what is to keep the outer from moving? I think they should be as in your drawing No.1. The shims on the central spacer are then selected to provide centralisation and pre-load.
Yes.As I understand it either both <> or >< not <<.

(ish, sorry not in drawing mode today.)
Just had a chat with our local Sunbeam owner , apparently his is an S8 , he was having trouble starting it possibly due to flooding but after our chat it started first time.
