The MO1/4 AQ/4 465115 which appeared for RE WD/D contract C/7945 appears in the civilian lists for 1940 150cc and 250cc models. This makes sense as C7945 was the composite July 1940 contract made up of various models and having the appearance of using up factory stock and spares.
It seems to have been interchangeble in all respects with the L1 type. The difference may have been as simple as the length of A/R cable or HT lead fitted to the complete assembly
Ron,
no it's "normal" maybe you've got the C 7374/5/1 or the C 7945/10/1 from May 1940,
but in April 1941 there is a part list for these 2 contract condensed in one book!!!
and they ad the carburetor and the electrical system...
the other pages are in photobucket..
find nothing about magdynos on the WD/G or WD/L part list or hints and tips books....
As so often, once one starts looking there is often more information available so I've attempted to correlate evrything that I can find. It's from multiple sources and is based as far as possible on definitive links, but E.&.O.E., of course. The lists commence with the pre-war MO1/0 as although not generally used for 'our' generation of WD machines, they may help identify one that's fitted. I've included the ring cam MSL1 for Norton as these were initially fitted to machines which saw wartime service.
The 1950s Lucas documentation clearly refers to 'MO' and not 'M0' although a zero is what appears to be stamped on the plates and the ' mark is shown as a full stroke.
In general, it's all quite logical and straightforward, with the exception of Royal Enfield and their plethora of models and variations. Although Triumph are shown in Lucas literature as 'L/0', the few plates that I have seen are stamped simply 'L'
The next task will be to try pinning down the dates of the changes and whether aluminium or brass plates were used.
Rik, Are you any further down the track with a list. I've 39-57, 50 Lucas parts manuals, the main bit that was giving me problems was the 'Type' info ( AC AG L etc.) I had originally come to think this was either 'Manufacturers Spec' codes or 'build operator' code. I think you are getting close to some understanding.
The /4/6 appears to be 'update changes' for say 1944 (4)and 1946 (6), these may not have occurred each year hence no /5's
The contract books look interesting as these may be the basis for the original variances ... i.e. agreed fitting for each unit/bike maker.
Unfortunately I have no access to these, are they available digitally somewhere ?
( have tried to open some of the links in these discussions but don't seem to link up properly)
With regard to the Type info. Could it be something to do with the fixing procedure? ie
"3" is quoted in the Ariel code and they have a 3 bolt fixing
"4" for Norton which have a 4 bolt fixing
BSA--RE--Triumph are fixed with a clamp.
So some have tapped holes and some have press in pegs in the base, if it's relevant at all Norton has a clockwise rotation and RE are all slack wire advance
Here's my original plate on the magdyno of my first contract WD-C Enfield, Think it came from the factory like this, as it's a numbers matching bike, left behind in France. I have no reason to believe the magdyno was ever changed.
Roy mentions brass inserts for the peg on a 1936 mag, my 1937 dated mag also has brass inserts, my 39 mag does not.
When did they change to full alu version 38 or 39?
Hello everyone, my name is Aumkar and I'm from India. This thread has been a massive resource and I want to thank everyone for all the information. I'd like to contribute as well.
My bike is a WD Royal Enfield 350 Bullet. Dispatched from the Redditch factory on 18th December 1952 to London based freight forwarders Hales Bros. It is one of a batch of 750 dispatched in Dec‘52/Jan’53 to Hales for onward shipment to Madras Motors that were destined for the Indian Army. The bikes of course were WD spec as can be traced in historical photos, furthermore my Ammeter and Smith's speedo all have the chrome delete like the WD bikes did.
My MagDyno : M01L 46030...6/8/0? the last digit's stamping is pretty much destroyed.
L1 1153? <----
The Plate is Aluminum. I don't have the option to upload an image or else I would have attached it.
There would be a market for the magneto which would fit most Enfields and the specification plate would certainly be desirable to someone building a late 1940 WD/C.
Yes, brass plate.
It is just the mag, no dynamo.
Not sure where I'd track down someone rebuilding a WD/C, it would be better on the motorcycle than on the Lister engine it ended up on.
I'd suggest a post in the "Sales" section here, preferably with a photo or two (it requires a separate photo host though but we can talk you through that or post a photo for you).
With a bit of luck, someone with a contract C6215 WD/C will be looking for this very magneto.
