Hi the old photo is off the net and the one on my table is my current toy regards Daren

[Foppoli Matteo]

Hello Daren Thank you for your answer
I need a tank and the gearbox, can you help me?
You know if the gearbox model 350 is equal to 600?
thanks Matteo

[Doug]

Hello Matteo,

The gearbox on the 350 and 600 models are not the same. Some of the smaller components may interchange, but the case has a wider mounting point on the 600, and the main shaft is longer.

[Foppoli Matteo]

hello Can you help me find gearbox and the tank, do you think my rear wheel is correct?
thanks Matteo

Matteo,

Sorry, I do not have the parts you are looking for.

The rear wheel looks like it is from a 350cc EW. The spokes are laced into the back of the brake drum. On the 600cc models from 1927 onward the brake drum is detachable via a conical spline. The spokes lace into the hub flange at both ends. The 600cc hub is machined rather than a sheet metal fabrication on the 350cc EW. The sprocket is soldered to the outside of the brake drum in both cases. The 600 uses a larger series roller chain for the final drive than the 350.

Hello members, you have the spare parts List  Douglas model E29?
thanks Matteo

[Foppoli Matteo]

hello members I need a new set of bearings for my wheel can you help? any information is appreciated
I also need the piece in the attached photo
thanks Matteo

Matteo,

The wheel bearings are a long obsolete taper roller bearing size. Timken and SKF were used. If you do a search of the forum, you should find the part numbers and dimensions. Douglas used two variants. The 600 generally used a 1/2 bore, and the 350cc used a 7/16 bore bearing; the height and outer diameter being the same. Later in the mid-thirties they used a lightweight 7/16 axle (and forks) for the front of the 600.

As for finding the bearings, you have two options. Scour bearing stockists for new old stock and be prepared to pay an outrageous price. You might as well replace the cone and the cup, as both usually go bad together. Especially the bearing situated on the side of the sprocket. The cup will be relatively cheap, it is the price of the cone that will give you heart failure!

The other option is to convert to modern sealed ball bearings. Again, details have already been posted. It will require new axles, bearing nuts, and sleeves to be made; but does not entail any irreversible modifications to your wheel hubs.

The brake arm was used on many different Douglas models. Generally as time went on the brake arms became more robust. Particularly at the rear where later on they also had a joggle to clear the frame. But you should be able to find a substitute. Or you can make new ones, which several folk have done already.

hello friends, It is correct for my bike?
thanks Matteo

[Doug]

No, that is an early 350EW gearbox that mounts on a platform (rather than the frame tubes).

Matteo,

That is a petrol tank for a 1931-32 500-600cc. These were the years of the "Tartan" side panels.

The one for the F29 would be similar in shape, but would have two filler caps; one for petrol and one for oil. The petrol tank in the picture did not require an oil compartment because the oil was kept in a sump below the engine.

Hi Matteo,

I afraid that the 2nd, petrol tank shown is not suitable either, it is probably off a 350cc sv which were made to comply with the British weight limit of 224 lbs, these were the models A/31 or A/32 which was built during the "Tartan Era of 1931/32"  The gear change was built into the right hand knee pad that bolts to the tank, hence to bolts fixings for the gear change gate on the right side from of the tank.   For 1932 the same tank was also used on the B/32 which was the slightly heavier 350cc sv, which in that year had lost it sump under the engine.  Also the C/32  - Bulldog, which was a light-wieght 500cc  which used the 350 cc  crankcases and crankshaft but used cylinders bored to 72 mm from memory give near enough to 500cc. The tank you are looking for is physically the same dimension as the first tank you photographed, but with the 2 caps, one for petrol and one for the seperate oil compartment which is built into the tank in a similar manner to the second tank shown.   
Just a thought some 250cc and 350cc models around 1934/5 were fitted to a similar style tank as E/29 and F/29 models, i.e. with an oil compartment, and had a gate gear change on the side of the tank, and probably just as rare as the tank for the 1929 models.   These were used for a short while before the more bulbous style of tank came in in 1935 that is associated with the later Aero models
Cheers and Good luck with the restoration.

Matteo,

Looks correct. The 600cc machines used a silencer that was slightly longer in the canister than the 350cc models. The body length should be about 18-3/8 inches. not including the tailpipe. The catalog image shows the canister painted black, and the tail pipe portion nickle plated.

Hello Thanks  thanks for your kind reply you tell me would like to know which of the magnet model goes on my Douglas Thanks Matteo

[Doug]

Yes, that is the one. Should be a BTH model M2 AD2. 1929 was the first year Douglas used the fully enclosed advance retard mechanism. In 1928 the same magneto had an exposed arm that the control cable attached to.

I hope it is correct gearbox and the petrol tank








[Attachments converted to linked images. 27Nov21 -Doug, Admin]

[Doug]

Matteo,

Petrol tank looks like it is correct.

Gearbox will have a WG/ prefix. WG/R, WG/T, WG/T/S denotes a later 1930-32 3-speed gearbox for the S5/S6/T6 model. I suppose these would work in a E/F28 and E/F29 model so long as it fits the frame and the chain alignment is o.k. The WG/T/S (which it looks like yours is stamped) would have an improved kick start quadrant over the WG/ an a different final sprocket (compared to the WG/T defualt sprocket).

-Doug

[Foppoli Matteo]

Hello, Doug  can you know the number of crown teeth on the gearbox,
The gearbox pinion?
And the number of wheel teeth?
thanks Matteo




[Attachments converted to linked images. 27Nov21 -Doug, Admin]

[Doug]

Matteo,

According to the E/F28 parts list (and I assume the 1929 would be the same) the flywheel clutch has an 18 tooth sprocket.

The gearbox input sprocket is 31 teeth.

The gearbox output sprocket had a range of options from 14 to 19 teeth. 18 teeth is the standard solo sprocket. 14 teeth is the standard combination (sidecar/outfit) sprocket.

The sprocket on the rear brake drum (wheel) is 51 teeth.

-Doug

[Foppoli Matteo]

A new piece Brown & Barlow  123-5.

[Doug]

Matteo,

This one:



The other (and cover) is for the S6 model.

-Doug

[Foppoli Matteo]

Hello Doug, thanks for your kind reply have you got the size of the dynamo's gear?
Do you know what the lighthouse is? BTH?
Thanks Matteo

[Doug]

Matteo,

The dynamo pinion is 14 teeth.

The headlamp would be BTH.

[Foppoli Matteo]

hello, Tool boxes are on this model? thanks Matteo

[Doug]

Matteo,

Yes.

An example of the 1928, the E28 is shown with the parcel carrier and the F28 with just the mudguard stay is attached. The mounting on the F28 must have been precarious. The presence of the parcel carrier or the mudguard stay is not definitive. My F28 was one of a consecutive pair shipped to Canada and both had parcel carriers (and foot pegs).

For 1929, it is the same. While the F29 is shown without toolboxes, they are mentioned in the description. The text for this was rather small so I did not include it in the scan.

-Doug

hello, Tool boxes are on this model? thanks Matteo

You've done a great job on this bike Matteo! Very impressive part-searching.

[Foppoli Matteo]

Hello, I'm looking for a kitstarter gear you can help me, or you have a design
I have little push to start the engine
maybe the lingering is not correct?

Thanks for your help
