Handling Precautions
Turn the
assembly over
and place the
wheels into
the cut-outs at
the front of the
underframe.
If the wheels don’t
rotate smoothly,
check the inside
edges of the axle
boxes for any
burrs, and remove
any found with a
half-round le.
If the wheels don’t
rotate smoothly,
check the inside
edges of the axle
boxes for any
burrs, and remove
any found with a
half-round le.
Position the wheels so that the
underframe rests in the groove of the axle
boxes.
Place the rst axle box guard
onto the underframe, aligning
the holes with those circled. Place the second 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.
Remove the tape from the axle
boxes. Then check that the wheels
rotate smoothly.
When moving the model, always
make sure that you pick it up at
both ends, never from just one.
When working on the side of
the model, place the model on a
cushioned work area, such as a
folded blanket, to avoid damaging
the model.
You will have noticed that the weight of the model has increased
considerably. So, from now on you will need to handle it carefully to avoid
dropping or damaging it.

Rod pin
Check over the coupling rods for any
burrs or casting ash. Remove any you
nd with a le, and then smooth with
wet and dry paper.
Remove the coupling rod, rod pin
and bush from the rst wheels. It is
advised that you keep these parts to
one side and separate from the other
parts so you don’t mix them up.
Lay the parts from Stage 4, 24, 25 and
26 (this stage) by the side of the model,
as shown on the left. Try to keep the
parts from the dierent stages separate
to avoid getting them mixed up.
To make it easier when tting the
coupling rods to the wheels they have
been colour coded, along with the rod
pins and bushes.

Insert the bush and rod pin from Stage 24 into
the hole created by the two coupling rods.
Then, tighten a nut onto the end of the rod pin.
Complete this process for the right coupling rods as well.
Hold the left coupling rods
from Stages 4 and 24, as shown,
and insert the front portion of
the rod from Stage 24 between
the split at the back end of the
rod from Stage 4 (arrow).
Repeat this process for the
coupling rods on the right side
of the model.
Turn the model over and use the rod on
the third wheels to check that the wheels
spin together, as shown.
Combine the front end
of the coupling rod from
Stage 26 with the back
end of the rod assembly,
insert the bush and rod
pin into the hole and
tighten a nut onto the
end of the pin.
Lay the model on
its side and position
the left coupling rod
assembly over the
pin projecting from
the third wheels
and align with the
corresponding holes
on the other wheels.
Insert the bushes
and rod pins into
the corresponding
holes in the
coupling rods over
wheels 1, 2 and 4,
as specied in Step
2. Tighten all of the
rod pins into the
holes.

In order to t the
connecting rod, you
will need to remove
the crosshead cover.
Use the wrench that
was supplied with
Stage 17.
Locate and remove
any burrs on the
connecting rods.
Lay out the crosshead cover, screws and
wrench, along with the two bushes from
Stage 25.
Ensure the nut is secured
on the end of the pin of the
crosshead cover.

projecting from
wheels 3 and the
smaller hole into
the recess in the
crosshead.
Place the
crosshead
cover back
into position,
with the pin in
the hole of the
connecting rod.
Lift the connecting
rod o of the pin of
the third wheels and
place the bush from
Stage 25 over the pin
and into the hole in
the coupling rods.
Place a bush
from this stage
over the pin
and then t the
connecting rod
over the bush.
Repeat this process to t the connecting
rod and eccentric arm on the right side of
the model, as shown below.
Rotate the wheels to
check that the wheels
and rods are all working
together.
Align the hole at
the back end of the
eccentric rod with that
of the left eccentric arm
and secure with a at-
head screw. Using masking tape, temporarily
secure an eccentric rod to each
connecting rod.
Now you can t the eccentric
rods. Use the photo on the left
to familiarise yourself with them,
to make sure you are tting the
correct one.
Place the eccentric arm, as shown, over
the end of the pin. Insert a 2 x 7mm
screw into the unthreaded side, and
tighten through into the threaded side.
Tighten the
screws back
into place.

To make the following steps
easier, it is advised that you

Assemble the parts as shown in the photo above, one set for the right side (top)
and one for the left (bottom). The circled areas should help you position the
parts correctly.
Lay the model on its right side. Insert
the piston valve spindle into the hole in the
piston valve tail guide, and the projection on
the expansion link inner plate into the hole in
the motion frame.
Loosen the screw holding the left
eccentric arm in position (circled). Repeat
for the right eccentric arm.
Adjust the position of the left
eccentric arm so that it is angled
about 10 degrees away from the
vertical line.
Follow the same process for the right side of
the model and then re-t the motion plate.
Tighten a 2 x 6mm screw through the hole
on the connecting link and into the hole at
the bottom of the crosshead.
Re-t the left motion plate to the side of
the motion frame.
Re-t the reverse link to the motion frame
and use a 2 x 3.6mm set screw to secure the
hanging link in the split at the end (circled).
Similarly, x the split end of the eccentric rod
to the bottom of the expansion link.
