Hello Daren Thank you for your answer
I need a tank and the gearbox, can you help me?

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.

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.

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.

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.

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.
