Insert a type G screw into one of
the washers.
Locate the holes in
the right frame half
(Stage 36). Check
the holes for any burrs or pieces of ash
left over from the casting process, such
as those circled in the inset. Turn the screw into the washer.
Push the projections into the holes.
Tighten one of the type G screws with
washer attached (from Step 9) into the
hole nearer the front of the frame half.
Use a le to remove any burrs or ash
you have found in the holes.
Repeat the process to combine another
type G screw and washer.
Take the fuel tank base and align the
projections with the corresponding
holes on the underside of the frame half,
as indicated by the arrows.

Take the rear brake spindle and align the
semi-circular hole with the semi-circular
projection of the rear brake pedal.
Screw the second type G screw and
washer into the hole nearer the rear of
the frame half. Push the spindle onto the rear brake
pedal.
Remove the masking tape from around
the bottom of the right frame half. Make
sure the brake pedal stays in place.
Push the rear brake into the spindle to
fully engage the two parts.
If the rear brake spindle doesn’t fit
If you have trouble tting the rear brake spindle onto the projection of the rear brake, you may need to open the hole in the
spindle up a bit more.
Inside of the hole of the rear brake
spindle are two raised parts that help
to hold it in place. You should avoid
altering these.
Use a le to reduce the thickness of the
wall of the other side of the hole, all the
way through.
When combining the spindle and
pedal, cover them with paper towel
and carefully squeeze together with
pliers. If the spindle still won’t t,
reduce the wall thickness a little more.

Turn the U-shaped end of the switch box
around and align it with the raised hole
in the frame.
The brake pedal and spindle should now
be engaged, as shown.
Temporarily secure the switch box cable
to the frame with masking tape.
Tighten the type A screw into the hole.
The head of the screw will hold the
U-shaped end of the switch box in place.
Insert a type A screw into the hole in the
frame, where the U-shaped end of the
switch box is.
Insert the projection of the switch box
into the hole in the frame (green arrow).
When you push the brake pedal down,
the end of the spindle will hit the button
in the switch box (inset). When all the
wiring is connected, this will activate the
brake light.
