and the short link. Then
insert a 2 x 8mm screw
through the link, from
one side to the other.
Hold a nut at the end of
the screw, and tighten the
screw into it.
Put a long bush in the hole of the
equaliser bar. Position a B spring over it,
and tighten a 2 x 8mm screw through

Tip!
Turn the assembly over and locate the two
U-shaped cut-outs on the underframe. Fit the wheel assembly from this stage into
the second cut-out. Remove the tape.
Position the wheels so that the
underframe rests in the groove of
the axle boxes.
If the wheels don’t
rotate smoothly,
then check the
inside edges of the
axle boxes for any
burrs. Remove any
found with a half-
round le.
Place the wheel assembly from
Stage 4 into the cut-out at the
front of the underframe.
Once both wheel sets are in position,
rotate them to check that the movement
is smooth. Be careful of the coupling rod.
Place an axle box guard onto
the underframe, aligning the
holes with those circled.
Tighten a 2 x 6mm
screw into the two holes
on the axle guard, securing it in
place. Repeat this process for the
remaining three guards.
Turn the assembly
back over and
tighten a screw
into the circled
holes on the leaf
springs to secure
them to the
ends of the long
parts of the
axle boxes.

The following two pages show you the variations
for the wheels, if you are choosing to paint them or
to leave them as they are.
Paint – (Matt black) Acrylic is used in these images, however, the body is
sprayed with a lacquer-based paint.
Paint thinner – one that is appropriate for the paint used.
Brush
Masking tape
Degreasing agent
Primer
The wheels are made
from a zinc alloy. If they
are left unpainted, you
are able to see the full
texture and details.
If you choose to paint
the wheels, the nished
model will more closely
resemble the real
locomotive.
Painted nish
Tools and materials required
Unpainted
Painted
D51 Paintwork Some parts, such as the
wheels, can be painted
even when xed to the
rest of the assembly.
The steps will continue
with assembling a non-
painted model.
You can choose to leave your model in its bare metal state, as
shown in the assembly steps, or to paint it black to match the
original locomotive.
There are three options for how to nish the wheels:
You can leave them unpainted, to showcase the zinc alloy
metal nish and the detail
You can paint just the inner area of each wheel, minus the
‘tyre’ area, to give a sense of depth to the model
Or you can paint everything but the outer surface, where the
wheels are in contact with the track.
Examples of wheels on the real train.

™
Bare metal nish
Spray the entire surface of the wheel with
a degreasing agent.
Apply masking tape to the axle between
the two wheels to protect it from the
paint. You don’t have to cover it, but it may
make it easier to paint the wheels.
Wipe away any paint that has run onto
areas of the wheel that you don’t want to
have painted.
Paint the wheel with black paint. If
you choose to prime the wheel before
painting, glue mixed with paint will
work well.
As the surface of the wheel isn’t perfectly
smooth, you will need to apply more than
one coat of paint.
Paint the inner surfaces of the wheels,
as shown above. When the paint is dry,
remove the masking tape.
