There are a few tips about the engine you may find useful. Supposedly the three types of point box are interchangeable. That is not quite right. Some of the pre war engines have a bigger diameter points operating cam in the flywheel. Only the pre war type points box provides enough points adjustment with these bigger cams.
Yes i know what you mean, from what i've found out so far the Pre-war engines have a brass points box thats a bit different in size to the normal one.
I converted my James Cadet to electronic ignition so i have a full set of electrics left from that, while they look very similar they just dont fit right, even the old brass flywheel is about 1/2 smaller on the Cadet.
The original 2E piston was cast iron. It is a heavy lump causing much vibration. The 196cc Super Sport piston is aluminium, one third the weight and dimensionally identical. It transforms the engine.
That is very good to hear, mine has at some point been fitted with an aluminium piston, plus i got 2 spare pistons with it, one is in reasonable condition with rings, the other will make a nice ornament once polished.
Very little is written about Albion gear box maintenance. The best available is found in Volume 1 of Newnes "Motor Cycle Repair and Upkeep" published 1931. The odd reprint appears on eBay or you can get copies of the relevant chapter from the usual sources. It's never a bother replacing bearings in an Albion box. They are either plain bronze or common metric sizes. I've never yet met an imperial size ball race in an Albion.
Cheers,
I got lucky in that someone put me onto a link where i got a parts list for my gearbox, if anyone else wants it its here.
http://www.barnstormers.co.nz/barnstormers/wp-content/uploads/2010/01/Albion-PDF-1.pdfMine is the E model, that list gives the bearing size as 2-1/4 x 1 x 5/8
After another tip off i found a company that has the bearing in stock and at £8.50 delivered thats not a bad result.
Thanks again i'll see if i can find a copy of that Albion book.
The James manuals i downloaded came from a website
http://klassiekrijden.nu/ which had about 500 manuals for all types of British bikes, i also downloaded about 20 Villiers manuals from there, but at the time had no interest in Pre war so never bothered downloading any of them!
The sad news is that site is no more, when you click on the link the domain name is for sale, but the person who originally owned the site must have all those manuals somewhere even if only in PDF format, hopefully he'll show up again it was a wonderful site with so much information to download, pity its gone.
