THE
PARTS COLLECTION
Please
note:
All the parts pictured in the menu items "Engines" to "More Parts" on the left, have been sold.
This page
has been left on-line as a guide to the pictures. For current Douglas Motorcycles and Parts for Sale please see
Douglas Motorcycles and Parts For Sale and Douglas Motorcycle Products and Services in the Douglas Motorcycle Forums.
The following information refers to the original Kynoch Douglas Parts Collection.

How
the Parts are organised
The parts
are organised into 18 major groups by the type of part - eg
Cylinder Heads. You can see the 18 groups on the left. Each
of those links takes you to an index page showing small photographs
of the parts included in that group. This
is how Alex had them stored in his workshop - eg all cylinder
heads from all machines are stored together.
The parts from the Triumph 500 Speed Twin are included in
the 18 groups of Douglas parts. The Triumph 250 is still assembled,
apart from the front wheel and front guard - so there are
no parts from that machine in the 18 groups.
As you can tell from the number of frames and engines, there's
a ratio of about 4-5 Douglas to 1 Triumph. So where you see
parts labelled "Douglas and Triumph", think in those
proportions.
How
to view enlargements
To
view an enlargement of any small photograph, click on
the picture itself, or the text underneath.
On
the enlarged photograph pages, you'll see a Back
and Next link in the top
left corner. The Back takes
you back to the index page for the group, while the
Next walks you through
all the enlarged photos in that group. |

What's
included in the Parts CollectionThese
photographs show approximately 95% of the collection. There
are some additional small parts not included here. I do not
have a written list of all the parts at this stage. I hope
to compile one with some help from Douglas enthusiasts who
might be able to match Alex's descriptions to the photos on
these pages.However,
Alex compiled a partial list of his parts back in the 1970's.
This list is shown below. It is not a list of the entire
Parts Collection.
However you may find his descriptions a useful guide to some
of the individual parts in the Collection. Please also see
John Holmes notes below.

Please
note, the above is not a list of the entire Parts Collection.John
Holmes notes on the Parts These
notes were kindly provided by John Holmes of Scotland. Originally
from Peterborough, Cambridgeshire, John has had a lifelong
interest in Douglas motorcycles. Currently a member of the
London Douglas MCC, he has owned a variety of Douglas from
a 1923 CW through to the last model produced, the Dragonfly.In the
1960's, he rebuilt and successfully raced his 1928 SW 5 Douglas
and is still the last person to have won a vintage road race
on a hand change Douglas.John went
through the whole site and made the following notes from the
photos.
Engines
OE engines are from OB models
EL engines are from DT or SW models, the engines with tall
air boxes eg. EL776 are earlier type [ 1928 ] , those with
a square air box are later [ 1929-30 ]Frames
HF frames = OB models - 600cc OHV. 1924+
LF frames = OC models - 600cc OHV. 1926+
TF 050 frame = DT/SW model - 1928- 30
Cylinders
Type 1 - DT/ SW model.
Type 2 - probably OB model.
Type 3 - could be OC model.
Tanks
Tank 1 - probably 1930+
Tank 2 - OB model.
Tank 3 - DT/SW model.
Tank 4 - DT/SW model.
Tank 5 - OB model.
Tank 6 - possibly a special sprint Tank.
Cylinder Heads
Type 1 - DT/SW
Type 2 - earlier OHV - probably OB or OC model.
The pre-DT heads had screw threads on the ports, whereas the
DT heads had a two stud flange fitting.
Wheels
Wheel 1 - DT/SW model.
Wheel 2 - DT/SW model.
Wheel 3 - DT model.FlywheelsFlywheels
2
Top left - OB model
Top middle - SW model.
Top right - OB model.
Bottom left - OB model.
Bottom middle - OB modelFlywheels
3
These are all brake drums and possibly from models OC, OE,
or even EW.Flywheels
& ring gears
Bottom left, SW model rear brake drum, sprocket and brake
back plate.
Bottom left, earlier type flywheel, could be from a 2/3 hp
SV Douglas.
Carbs
Those with a flange fitting induction pipe are DT/SW, those
with a screw on nut are OB/OC model types.Carbs
3
Mainly induction pipes.
Bottom left - OB model.
Two stud flange fitting DT/SW model.
Screw on ie. round flange fitting are earlier, OB/OC model.
Exhausts
Pipe 1 - DT/SW.
Pipes 2&3 - OB/OC model.
Gearbox casings
These
all look to be DT/SW and should have the letters, YG followed
by a number, or possibly the letters AG or even UG.
Gearbox Parts 1
Probably OB model.
The output shaft of the DT/SW's has a tapered course spline
on the end so that you could easily change the sprocket, whereas
this pic. shows a keyed taper.Gearbox
Parts 2
Use the above info and look at the output shaft taper.Gearbox
Parts 3
Not sure, sorry! but Douglas.Gearbox
Parts 4
Possibly OB or OC model.Gearbox
Parts 5
OB or OC.
Casings 1
Top left - airbox for an early [1928] DT/SW.
Sorry, don't recognise the others.Casings
2
Two on the left are OB model gearbox to rear wheel covers.
Two on the right are DT/SW primary chain / gearbox covers.Casings
3
Probably OB model.
Clutches
The only one I recognise is the left one in the middle row
which is an SW model. The multi plates are probably Triumph
as Douglas favoured fly wheel clutches ala cars.
Assembly
Triumph!
Guards
Rear guard 1
This has to be SW, it even tells you the cc of the engine!
Small parts 2-6
Most are SW/OB/OC flywheel clutch parts, ie. Douglas.Small
parts 2-7
The 'rings' with the 'arms' are clutch activating arms for
SW, OB, or OC models.Small
parts 2-11
Douglas, DT/SW engine tie bars, to clamp the engine to the
lower horizontal frame tubes. Two per engine, EL type.Small
parts 2-12
All OB or OC model rocker grease/oil reservoirs, the lower
R having rockers visible.Small
parts 3-4
Douglas DT/SW rocker grease/oil reservoirs.
Sprockets 1
Probably OB or OC rear wheel sprockets.Sprockets
2
Lower row of three, DT/SW gearbox input .Sprockets
3
Gearbox input, Douglas.Sprockets
4
The ones with the coarse tapered splines are DT/SW [very useful].
The ones with a tapered hole AND a keyway are OB/OC.
The flat ones are probably Triumph.Further
