The electric radiator fan is controlled by a
thermostatic switch which operates when
the ignition is in the 'on' position. Whilst
working on a hot engine ensure that the
ignition is switched off.
Do not remove coolant expansion bottle
cap whilst coolant is hot. Take
precautions to prevent scalds.
Correct use of fixings is required in order
to ensure full engagement of the nyloc
nut.
Cautions
All brake connections must be kept
spotlessly clean and contamination with
oil, water and petrol should be avoided.
When drilling fibreglass use tape on the
surface over the drill holes to prevent
damage to the gel coat or painted finish.
Slow drill speeds must be used.
Do not over-tighten thermostatic fan
switch.
Both imperial and metric threads are used
on the de dion brake pipes. The threads
on the three way union are imperial whilst
those on the brake callipers are metric.
To aid recognition a small notch is
machined into the hexagon of the metric
unions.
Retighten wheel nuts after 200 miles.
Ensure adhesive is applied in a wellventilated area. Follow instructions on
adhesive packaging. Care must be taken
whilst working in a confined area, for
instance the footwell.
Use a suitable face mask to prevent
inhalation of dust when drilling fibreglass
or carbon fibre.

2.0) Kit contents
The following pages include pictures and tables to assist with part recognition and location.
Due to the multiple permutations that can be produced it is impossible to show the exact
locations of every part. However the pictures have been laid out in such a way that each
picture represents what you should expect to find in a particular box.
2.1)

IMPORTANT NOTE
The following pages are provided as a guide to aid recognition of parts. The packages
shown will not be an exact representation of what you should expect to find in the packages
supplied with your kit and should therefore not be used as a parts check list.

3.0) Pre-assembly information
This section has been included to aid recognition of parts and to give a basic idea as to
where they might be found. Due to the complexity of the range of options available and
subsequent variations on packages it is impossible to list every permutation; however Table
5 (below) and Annex A (at the end of this section) show the normal location of parts in a
standard CKD kit.
3.1) Package contents
Kits supplied from Caterham Cars arrive as shown in Fig 21. Due to packaging constraints
some items may be located in different packages.

Figure 31: Bodywork protection
The following section covers the assembly
and installation of all areas of the front

It is recommended that the front wings are
not fitted until the front suspension is
assembled and the engine installed. This
reduces the risk of damage to the wings
and maintains easy access to the engine

essential that this task is carried out on

Page | 70
NOTE
Lowering the platforms will decrease ride
height, and raising the platforms will
increase ride height. For the best results
the ride height should be set with the
driver in the car and fuel in the tank.
1. Start by adjusting the front dampers to
achieve a minimum distance of 150 mm
(this can be increased for road use to a
maximum of 190 mm) between the ground
and the bottom of the lower chassis rail,
where the rear leg of the front lower
wishbone exits the side of the car. This
measurement should be the same on both
sides with the car loaded.
2. Now adjust the rear dampers in the
same manner to achieve a height 15 mm
higher than the front, measured to the
underside of the lower chassis rail
immediately in front of the 'A' frame
mounting point.
NOTE
Adjusting the rear may have an effect on
the front therefore it is good practice to
check between front and rear several
times during adjustment
3. Once the desired ride heights have
been set ensure that the platforms are
locked together to avoid movement.

9.2) Preparation
It is recommended that the lower chassis
tubes that will be under the De Dion tube
are protected. Several layers of masking
tape or a thin card taped to the tubes is
sufficient.
With the fixing boss offset towards the RH
side of the tube fit the three way union
(polythene bag marked 'rear axle') to the
threaded stud situated towards the RH
end of the De Dion tube, refer to Figure
125, and secure using a nyloc nut

12.8) Headlight beam setting
If possible the headlight beam setting
should be carried out using professional
equipment; if such equipment is not
available, proceed as detailed below:
1. Position the car on a firm level
surface, 2 m from a vertical surface
(measured from the front edge of the
lower lip of the nose cone). Slacken the
headlight securing nuts and switch on the
lights (dipped). Adjust the lights until the
brightest spot of each light pool (at the
apex of the dip-beam cut-off) is 650 mm
above the ground.
2. Measure the distance between the
centres of the headlights on the car and
the distance between the centres of the
bright spots on the wall. Adjust the
headlights as necessary until the two
