118 Emission Control
Installed view of the charcoal canister.
When the engine is at rest, fuel vapor through
evaporation gradually fills the air space in the fuel
tank. The sealed filler cap pr events the escape of this
vapor and pressure builds up within the system,
forcing the vapor to flow into the charcoal canister
which is located in the engine compartment beneath
the windscreen wiper motor.
The fuel check valve prevents liquid fuel entering
the charcoal canister when the fuel tank is full or the
vehicle is parked on a steep incline. When the engine
is running, the vapor is drawn via a hose from the
charcoal canister to the throttle body and burnt in the
combustion chambers.
TO RENEW CHARCOAL CANISTER
(1) Suitably mark and disconnect the hoses from
the canister. (2) Release the retaining spring and remove the
canister from the engine compartment. Installation is a reversal of the removal procedure.
TO RENEW FUEL CHECK VALVE
(1) Disconnect the negative battery terminal.
(2) Raise the rear of the vehicle and support it
on chassis stands. Remove the left hand rear wheel. (3) Drain the fuel from the fuel tank using a
hand pump or a suitable siphon. Do not siphon fuel
using the mouth.
(4) Remove the hoses from the check valve.
(5) Squeeze the retaining clip and remove the
check valve from the mounting bracket. Installation is a reversal of the removal procedure.
TO SERVICE THE SYSTEM
(1) Inspect the vacuum lines and connectors for
signs of leakage, cracks and deterioration and renew
as necessary. (2) Remove the fuel tank cap and check that a
slight resistance is felt, when vacuum is applied to the
one-way relief valve in the centre of the cap. Renew the fuel tank cap if no resistance is felt or
if the valve is blocked.
(3) Inspect the fuel tank cap seal for deteriora-
tion. Renew as necessary.

RELEASE BEARING NOISE
(1) Dry or worn release bearing: Check and
renew the release bearing.
(2) Damaged pressure plate diaphragm spring;
Check and renew the pressure plate assembly.
NOTE: Lightly depress the clutch pedal with
the engine running to check for release
bearing noise. If the release bearing is faulty
and has to be renewed, always check the
other clutch components.
Check the diaphragm spring fingers for scoring and damage.
2. DESCRIPTION
The clutch consists of a single, dry, driven plate
assembly, splined to slide on the transaxle input shaft.
A diaphragm spring type pr essure plate assembly is
bolted to the engine flywheel.
The driven plate is sandwiched between the
pressure plate and the flywheel and transmits the
drive from the engine to the transaxle.
Cushion rubbers are interposed between the hub
of the driven plate assembly and the plate friction
surfaces in order to cushion the drive.
The release mechanism is actuated by the clutch
pedal through a cable to the release lever and bearing.
Operation of the clutch pedal moves the release
lever which pushes the release bearing into contact
with the diaphragm spring fingers, forcing the dia-
phragm centre towards the flywheel. When the outer
edge of the diaphragm deflects, the clutch is caused to
disengage.
Clutch pedal free play is adjusted at the release
lever end of the clutch cable.
Clutch pedal height is adjusted at the pedal stop
on the pedal mounting bracket located under the
dashboard.

TO REMOVE AND INSTAL
(1) Disconnect the negative battery terminal.
(2) Using a small screwdriver, carefully prise the
centre ornament from the steering wheel.
View of the steering wheel removed from the vehicle.
Steering wheels may vary between models.
1. DESCRIPTION
The steering gear is a rack and p i n i o n type
which is mounted on the lower section of the engine
compartment bulkhead by rubber mountings and
brackets.
The design of this assembly requires a range of
special tools to dismantle and assemble the steering
gear. If the steering gear is found to have a fault which
requires overhaul of the rack and pinion, it is recom-
mended that this be performed by an authorized work-
shop or steering specialist.
However, the procedures for the removal and
installation of the steering gear and the renewal of the
tie rods, the tie rod ends and the rubber boots are fully
covered in this section.
The rack and pinion assembly requires no lubri-
cation during service.
The steering column is of the energy absorbing
type designed to compress in the event of a severe
front end collision. The energy absorbing units are the
outer steering column, the tilt bracket and the steering
shaft. All these units shoul d be handled with extreme
care if service operations are performed on the
steering column assembly.
(3) Remove the steering wh eel retaining nut and
mark the steering shaft and steering wheel hub in
relation to each other as an aid to assembly.
(4) Remove the steering wheel from the steering
shaft.
NOTE: If the steering wheel will not sepa-
rate from the steering shaft, loosen the horn
pad retaining screws at the rear of the
steering wheel and withdraw the horn pad
after disconnecting the wire. A puller can
now be used to pull the steering wheel from
the steering shaft. Do not strike the end of
the steering shaft as sharp blows can cause
irreparable damage to the collapsible steer-
ing shaft.
(5) If necessary the steering wheel can be dis-

dure with attention to the following points:
(1) Using large Stillsons and a large adjustable
spanner, install the tie rod and ball housing
assemblies
to the rack. Tighten the ball housings to the specified
torque.
NOTE: To avoid damage to the rack or
pinion the adjustable spanner must be
firmly tightened over the rack teeth and the
rack must not be allowed to rotate when
installing the ball housings.
(2) Measure a point 9 mm in from the rear face
of the ball housing of the rack and at 90 deg to the
rack teeth. Centre punch this point.
(3) At this point drill a 4 mm hole, 10 mm deep
through the rack and into the ball housing thread.
(4) Place a locking pin above the hole and drive
it into position.
(5) Lubricate the rack, rack teeth and t i e rod
boot groove with suitable EPL 1 grease. (6) Install the rack boots and secure with the
clamps. Renew the clamps if necessary. (7) Install the tie rod end locknuts and then the
tie rod ends, ensuring that they are screwed on the
same number of turns as was necessary to remove
them.
(8) Tighten the locknuts to the specified torque.
(9) Install the mounting rubbers and brackets
to
the steering gear as noted on removal. (10) Install the steering gear assembly to

Raise the front of the vehicle and support it
on chassis stands. (2) Remove the relevant front wheel.
(3) Loosen the tie rod end locknut and remove
the tie rod end castellated nut. Disconnect the tie rod
from the steering arm by plac ing a suitable dolly or
hammer against one side of the steering arm eye and
striking the opposite side with a hammer. (4) Unscrew the tie rod end from the tie rod,
noting the number of turns necessary to remove it.
(5) Screw the new tie rod end onto the t i e rod
the same number of turn s noted during removal.
(6) Connect the t i e rod to the steering arm and
install the castellated nut. Tighten the nut to the
specified torque and secure it with a new split pin.
(7) Install the front wheel and lower the vehicle
to the ground. (8) Check and if necessary, adjust the front
wheel toe in as described in the Front Suspension
section. Ensure that the rubber boots are not distorted
or twisted on the tie rod when the adjustment is
completed.
