It was a 6-cylinder vertical water cooled engine with
separate steel cylinders. These were encased in
a pressed steel water jackets. Each cylinder had twin inlet
and exhaust valves and 2 spark plugs on the inlet side
only. The crankcase and pistons were made of (mostly)
aluminum. The two magnetos are set at 52 degrees of
the vertical cam shaft at the front of the engine and are
controlled automatically by the throttle. An air pump is
positioned on top of the rocker case, and the water pump
is at the rear of the crankcase.
Kit parts
The engine comes on a single sprue. In “ProfiPACK”
versions of the kit there will be additional parts on
a PE fret. In all there are 12 plastic parts to the engine
and an additional 6 PE parts. The parts are moulded in
great detail and are crisp. There are no sink or pin marks
anywhere that I could see.
Colours
Either follow the Eduard colour guide for the engine parts
or paint parts according to the references. A couple of
points to note from the RAE report are that the HT cable
carrier was “red sheet fabric”, and that the inlet pipes
were “galvanised steel lagged with asbestos”.
Build Steps
1. Assemble the engine block and add the rocker cover,
parts X 1, 8 and 9. Paint according to the painting guide
or references. Add the name plate PE part if necessary.
At this stage you can either add parts X11 to the rocker
cover and cylinder heads or scratch build some valve
springs. I chose the latter option and made some valve
springs by winding a length of wire round a #80 drill bit
as shown.
2. Add the PE labels and gaskets, if applicable.
3. Add the magneto assembly, parts X2 and X10(2).
Not that the magnetos are supposed to be at an angle
of 104o to each other, and not 90o. A right angle will
cause you some problems with later fittings.
4. Additional scratch building step - Add HT cabled
to the spark plugs and join them to the cable carrier.
Wire the magnetos to the cable carrier. I used short
lengths of copper wire to do this CA glued into position.
5. Add the air pump, X6 and the carburettor, X12,
and the PE plate 13 if applicable.
6. Add the cooling system to the engine block and the
cylinder cooling jackets. X7, 3, 13. NB the exploded
view in the instructions may showX5 and X3 incorrectly
positioned. Part X3 should be above part X5, as in the
diagram shown here.
