Like I said , I THINK it was "D's" that this was standard as It's only the one wheel I've come across like it, as the works were doing a lot of cost cutting exercises about this time.

Actually I don´t know what that is all about. You can fit taper roller bearings just as well as standard ball bearings, as the majority of Japanese or Italian bikes have. BUT, I would not go for adjustable bearing features, too big a risk of wrong setting in a hurry. I´d fabricate a distance tube for the inner races, ball bearing or taper, same for all. That distance tube is fitted next to your lathe and adjusted in total length for nil axial play. In the bike you simply torque up the wheel for rigidity , no hassle with bearing preloads in consequence. The picture shows a mod from non bike scenery for inspiration, the big diameter discs there to keep the grease in the taper roller bearings.

That is a tremendously generous offer Marcus, by stripped down = brake hubs and rim off?

Further inspection, after referring to David's supplied drawing (thank you) there is what appears to be the remains of the outer taper cage in the hub on one side at least and this has had the leading edge bludgeoned by some monkey, it maybe that this would preclude re establishing the taper bearing set up without removing, building up and re machining. Also, the speedo drive gear has been welded on !!.

All this makes me think that someone considered replacing the adjustable bearing and after subjecting the area to brute force, heat and a total lack of mechanical sympathy failed and reverted to the non adjustable bearing solution.

Am I right in thinking that the hollow axle would differ in length depending on if it was fitted with taper rollers or bodged non adjustable 'shady tree' solution. ?

I'll need to consider options and then maybe a short holiday in the beautiful west country.

mmm. doing a search on this Chankly Bore wrote on this topic

'The hub and the axle are special components requiring various spacers listed in the 1952 Spares List Supplement and now unobtainable". K.T.B. page 44. Ball bearing was listed as H22/2, and the spacers may have been H59-H59/3 inclusive, hub body may have been H38/7 or H38/9.'

this makes me think that contrary to my thoughts that the original hub was adapted that there was a stand alone purpose made hub for unadjustable bearing version.

Does anyone have dim's for ET94 as the measurements and markings from the JAL bearing I've taken do not turn anything up.

I thought that the ET94 was an imperial bearing RLS 6.

I am not certain what the bore of your hub is. I have never seen this type of hub. If you are not looking for strictly original I would just match the bearing to the hubs and hollow axles that you have.
