There are online copies of the manual and parts book.

The parts drawings at Andover Norton are also useful.
Use the Fig.H3(a) diagram in the manual for the rear wheel assembly because the parts book diagram isn't completely accurate, also note that some copies of the Mk3 manual say in section H4, that the rear wheel lock ring is LEFT HAND thread, which is not correct, it's RH.
Regarding the "left hand thread" error in the shop manual, are you referring to page H3, left hand column, bottom paragraph? If so, I've managed to edit that out [and correct a host of spelling & syntax errors on the page]. I'm going to contact you via PM so that I can email you a copy of where I think the error is [it's in the version of the Shop Manual you have linked above] and a copy of my edited [corrected] page to have you verify. I can then replace that page in the manual. I'll make the corrected manual available to any member who requests it, once I've got it fixed.
Does anyone know of any other errors in the MkIII shop manual?
Regarding downloading the Parts Catalog, I find the one available on the britmoto site to be easier to deal with. See
Thank you for providing us with those links above. I still have my paper versions [purchased in 1984]. However, you can easily enlarge PDF files [old guy eye syndrome] and it's easier to get oily fingerprints off my computer screen!
