EW 350 1926

[Andreas]

Dear all,

attached a foto of the engine of my EW 350 1926. I would like to ask you to check the oil pipe from tank to engine. There is only one pipe. All other EWs from 1926 and 1927 I ever have seen from fotos have 2 pipes (to the engine and back). Is there any explanation? Thank you.

Andreas,

Early EWs had a mechanical gear pump. These had a single oil line to the timing chest. These relied on vacuum generated by the pump to lift oil from the tank compartment and through the sight glass. The system was simple, but prone to air leaks which disrupted the oil supply. In 1926 it was superseded by the timing chest with two oil lines. Gravity ran oil from the tank compartment to the first stage of the oil pump, from where it was pumped up through the sightglass. There is a fuller description in a previous post; search for EW oil pump. I would insert the link but it is not easy when replying from a smartphone.

Anyway, a single oil line is correct for an early EW.

Doug.

Dear Tom, dear Doug,

Thanks for your explanation. Engine number is YE3661, frame number MF3583. Can you find out if it is 1926 or earlier?

Andreas, If you look under identifying Douglas models you will see a timeline with information about the EW.
Have you anymore pictures of your machine, it seems yours has a vee type rear brake on it which may indicate that the rear wheel is incorrect. It would be interesting to see more details.
Hope this helps. Regards, Colin.

Hi Colin, Tanks for your help. You are right, rear wheel is probably BSA. I have another two Douglas wheels (one of them is a rear) with drums but no brake. I hope I will find it within the next years.

Hi Andreas,
I notice from the London Douglas machine register, (which we are in the process of updating and hope to publish shortly!) that you have recently entered your bike details,
from this it would seem that you bike is a fairly early model which fits neatly into our data as 1926. the engine number and the oiling system fitted also fits the early period as confirmed by Doug's observation.
Although dates are quoted for 1925 ew's our records only show 3 as being registered as 1925. It would seem therefore that hardly any were registered before 1926. Of course if anybody knows differently PLEASE let us see any evidence!
We do have over 160 ew on our files so the data is fairly comprehensive the lowest frame on record is MF466 and the highest 22742 so the survival rate isn't that good!
I note that we do not have the gearbox number of your bike, we would be grateful for that sometime as it again helps fill in data for future reference.
Good luck with your rebuild, I think you have more than a few days work!!:

Andreas,

The EW handbooks give a rough cut-off date for the engine serial number for when they stopped the single oil pipe and switched to the two oil lines. Unfortunately I am traveling at the moment and do not have access  to the handbook.

Hi Doug,
Thanks for the info, I will chase it up here in the UK, it is the sort of info we are attempting to collate for future reference, have to confess Until now I haven't read any EW handbooks!

Hi Andreas

If you look on the Barnstormers.co.nz site under manuals, look under older entries you will find a copy of the 1926-1930 Douglas 350cc manual which you can download in pdf format.  It has diagrams which show the differences in the oil systems, and may be of use to you.

Hi Steve,

Many thanks for your hint. Any idea is of help for my project.

Hi Dave,

to complete the datas of my EW, here the number of the gearbox: RG 3618. Hope this is of help. If you have any new conclusion, please let me know.

Andreas

[David Lawrence]

Hi Andreas,
Thank you for the data on the EW. I will make sure it gets into the register when we print it soon!
Regarding the EW manual, we have been thinking of printing some copies, They would be about £8 or £9 each if anybody would be interested please let me know on my direct email address law-27@sky.com

Andreas, re the EW manual, if you go to, www.barnstormers.co.nz/wp-content/uploads/11/EW you will be able to download the whole manual.
Best of luck,
Roy.

[Andreas]

Hi Roy,

Thank you very much for this information. I just printed the manuel - great!

Andreas,

As you will note from the handbook, depending on edition, engines after YE6500 or YE6418 were fitted with the improved oiling system using two pipes to the timing chest cover. The factory offered an exchange service to convert earlier single tube oiling systems to the later system, and many were likely converted when troubles began.
