Does anyone have the specifications for the oil inlet valve spring for early 2 3/4 engines - Part number 424.   I have tried to order one from the club spares but apparently Jeff Swan is indisposed at the moment.

Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

Wasn't the W20 new for 1920 ?
Kickstart mechanism.

What model(s) had 3 speeds and a clutch and kickstarter prior.
The WD continued on in its plain basic specification even after the war
Old habits die hard, and extras cost extra !

Most informative - civvy production continued to 1916.

Good evening,  the 1916 manual/ spares list lists both 2 and 3 speed options for kick start and clutch and the parts used are the same as the ones used on my 1919 W20.
So yes it would be possible but finding all the bits ????

General Douglas Discussion / Frame number location
Last post by Rob - Yesterday at 12:48
I am trying to locate the frame number on a frame I suspect to be a 1913 or 1914. The paint is quite good so I would like to scratch in the right location.

 I can't see any signs of numbers at the usual location for a TS frame.  

Any help would be appreciated.

Teens WD Duggies would have had neither a clutch nor a kickstarter.
What are you going to fit that would give them that capability ?
Thats sort of re-writing history a bit.
Push and run and hop aboard was the very essence of these bikes

Will watch with curiousity to see if anyone has conquered this 'challenge'.
Perhaps a tensioner pulley on the belt ?
But maybe we are shopping in the wrong neighborhood here .

I went with an EW because it has a newfangled clutch and gearbox and brakes. !
Douglas was a shade slow adapting to a changed world...
Hopethishelps !

Thanks Doug for the reply I shall open the box again this coming weekend and remove the spring and see what difference it makes to the start mechanism.

Again many thanks

Colin,

A 4-speed box for a 1932-33 era would have a prefix of GB/ and would not be a constant mesh kickstart. A T/ prefix is for a 1936 500/600cc Aero model. That had the constant mesh kickstart, and that looks like what you have. Those should not have a spring pushing the ratchet pinion into contact. They rely on inertia and the quick start thread of the Bendix to kick the face ratchet into mesh. (Introduced 1934 on the 4-speed 'boxes.) Then once the bike starts it spins it out of mesh. The Bendix thread is on a sleeve that needs to spin freely on its stud, as well as the Bendix thread itself, for it to work properly. These get gacked up and sticky. Do not grease them, use a very light oil or a dry film type lube.

The parts list scan is for the 3-speed gearbox. Note the kickstart spring for the 3- and 4-speed boxes are slightly different. The LDMCC Spare prewar department usually stock both.

Newbie looking at a 1919 WD 2-3/4 with a two speed gearbox but no clutch that is for sale locally.  Are clutch assemblies available?  How about kick start assemblies? Regards, Scot Taylor

Genuine handlebar links (28734) were painted, die cast alloy. The clamp part often cracked if the correct liners were not used - they should be an 'odd' thickness - about .080", but are often replaced by items cut from steel tube - thus causing the links to fracture.

Regards,
              Eddie.

I am looking for 1 x  'link for handle bar' part no. 28734 to fit a 1950 Mk IV.

My bike has one chrome, the other stainless steel so although I would prefer chrome, either will do as I want them to match

I've check the club parts list but can't see the item listed.

Thanks for reading.
