Douglas Motorcycles - General Discussion / Re: Petrol Tank Cap T35
« Last post by hoejmark on 05 Dec 2021 at 17:39  »
Hi Michael
I am not sure if the petrol tank cap for the T35 and MK V are equal. However I had to make a new one for my MK V as the old one had a crack. I made it out of a piece of solid brass bar and plated it with Replica Chrome form Gateros Ltd. The spring blade and the chain bow, I took from the old cap.
The groove that connets to the breather hole appears in the drawing sketch to be in line with the two screws for the spring blade attachment, but actually I made it square to these screw holes.

I attach my  drawing sketch for the petrol tank cap, and will try to post some photos also.

Regards

Hi Darryl,

Have a look at this thread. I think we decided that the TS/CW used the larger thread at the cylinder end, with the EW using the smaller.

The 7/16-20 thread is pretty common - it's actually a cycle thread.

Cheers

Douglas Motorcycles - General Discussion / Non-return oil valve for CW
« Last post by Darryl on 05 Dec 2021 at 05:31  »
Dear All
Was wondering whether anyone could assist me in identifying the brass male/male joiner 7/16 - 20 Tpi (I think) that joins the oil line to the crankcase of the CW Douglas. I am told it incorporate a non-return valve and that a drawing was available on the forum. The only one I can find is this one - Drawings for non-return oil valve, Models CO, 600EW, F28, 350EW posted the 24/10/21 is this valve and dimensions the same for the CW.
Thanks for any assistance you can provide.

Hi thanks for the reply. I think, due to the saw cut along the length where they went slightly too far its a post factory mod but its not structural so I'll leave it as is.

I am told that a petrol cap of a Rudge is the same and the Rudge club do stock them.

Hi Chris

As you had no response can I suggest that it may have been modified to take some form of side stand? My son has a Z frame but the bike was built as an Aero 500. Whether this was done at the factory or by a subsequent owner is not known.

I,m missing a petrol tank cap for a T35 tank. (for my new projekt)
It seems hard to find.
I would like a cap in any condition.
Has anyone experience in reproduction or make other caps fit to the T35 tank?

Thanks Eddie, all fits on snugly now after attacking it with the file. Incidentally, the cover is made of about 1/8" thick alloy, the cut aways on it were hand made and not deep enough and the holding studs had been replaced, so I suppose it  probably was a repro one. Thanks for help, much appreciated as always. Paul J
