or insuring a vehicle, it may be necessary to quote
various vehicle identification codes. The location of
these codes are as follows: The Engine Number is stamped on the front
face
of the engine block below No. 4 spark plug. The Chassis Number is stamped on the bulkhead
above and to the right of the brake booster. The Vehicle Identification Plate is located on the
bulkhead to the left of the MAP sensor and contains
codings relating to body style, engine capacity,
model,
transaxle type, engine number, paint, trim and build
date. The Compliance Plate contains information on
the vehicle make, model, month and year of manu-
facture, chassis number, seating, capacity and the
Australian Design Rules (ADR) with which the vehi-
cle complies. This plate is affixed to the bulkhead
above and to the left of the brake booster. The Tire Placard, which is located on the inside
of the glove compartment, contains information
on
the tire size, rim size, tire pressure and load ratings.

Method of checking cylinder head for distortion.
(3) Carefully clean the deposits from the inlet
and exhaust ports, the auxiliary passages, the valve
guides and the manifolds, taking care not to damage
any mating surfaces. (4) Clean the cylinder head mounting faces,
wash the cylinder head in solvent and dry with
compressed air. Blow through all the oil holes with
compressed air to ensure that they are not blocked. (5) Check the cylinder head for distortion diag-
onally and lengthwise using a straight edge and feeler
gauges. Refer to Specifications for the distortion and
machining limits. (6) Check the cylinder head face and combus-
tion chambers for cracks, burn marks and corrosion. (7) Check the valve stem to guide clearance. If
the clearance is in excess of the Specifications, the
valve guide must be reamed and the appropriate
oversize valve installed. (8) Inspect the valve seats for pitting or burning
and if necessary, recut the seats with a valve seat
cutter to the recommended angle. When the seats are
correctly finished, the seat widths should conform to
the Specifications. (9) Lap the valves to the valve seats with a fine
lapping compound. Apply a smear of Prussian blue to
the valves or their respective seats to ensure that true
and concentric seating has been gained.

(10) Install each valve in its respective port
and
check the valve stem height above the cylinder head.
Refer to the illustration. The extended height must
not exceed 18.4 mm. If the height exceeds the
Specifications, the valve or the cylinder head must be
renewed. Do not remove any material from the valve
stem tip.
(11) Check the valve spring tensions and compare
with the Specifications.
Check that the springs are not bent or distorted.

If a spring tester is not available, check the springs
by comparison with new springs. This can be done
using a surface plate and stra ight edge for checking the
free length and using a new spring and a used spring
loaded in a vice end on end, with a plate in between.
Measure from the plate to the vice jaw adjacent to
both the new and used springs. A used spring is
serviceable if it does not show collapse in excess of
five percent when subjected to this comparison test.

(12) Check the exhaust valve rotators for wear
and ensure that the rotators turn freely. (13) Clean the cylinder block face of all carbon
and rust deposits and ensure that all old gaskets are
removed. Do not allow the waste deposits to enter the
oil or water galleries. Clean all waste materials from the cylinder bores.

TO ASSEMBLE
Assembly is a reversal of the dismantling proce-
dure with attention to the following points:

(1) Lubricate all component wear surfaces with
engine oil before assembly to ensure adequate lubri-
cation when starting. (2) If the oil pressure relief valve was removed
from the cylinder head, proceed as follows:
(a) Using a brass tube inserted in the welch plug
hole at the distributor end of the cylinder head, tap
the relief valve into position. (b) Install the welch plug and the recessed screw
in their respective positions, after coating the plug and
the screw with Loctite 242 or equivalent.
(3) Install the inlet valve spring seats and
the
exhaust valve rotators over the valve guides before
installing the valve stem seals onto the valve guides.
(4) Install the valve stem seals, ensuring that
the
rib of the moulding on the inside of the seal is
correctly positioned in the groove of the valve guide
and that the spring clip retainer is correctly posi-
tioned.
NOTE: The valve stem seals can be posi-
tioned correctly and without damage using
an upturned valve spring retainer.

(5) Install the valves to their original location in
the cylinder head. Use care when installing the valves
to prevent damage to the seals.
(6) Install the valve springs, retainers and
collets.
Ensure that the valve retain ing collets are fully seated
Dimension A is the correct position to measure the
valve stem installed height. Dimension A = 18.4 mm.

Renew the clutch driven plate if the friction material is
worn down to, or is within 0.3 mm of the rivets.
NOTE: In most cases clutch slippage is first
evident by a marked increase in engine revs,
for no apparent reason, when pulling up a
steep hill. The clutch condition can be
positively diagnosed as follows: With the
handbrake firmly applied, and the rear
wheels chocked, select top gear and release
the clutch with the engine running at ap-
proximately 2 000 rpm. Clutch slippage is
evident if the engine does not stall. Make the
test as quickly as possible to prevent any
further clutch damage.

Check and renew the clutch cable. (2) Worn or damaged release mechanism: Check
and renew components as necessary. (3) Insufficient pedal height: Check and adjust
the pedal height.
(4) Warped clutch driven plate: Renew the
clutch driven plate. (5) Excessive clutch release lever free play:
Check and adjust the release lever free play to
Specifications.
NOTE: Visually check that the clutch cable
operates the release lever before removing
the clutch for inspection.

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.

bolt. (4) Install the rear wheels and lower the
vehicle
to the ground. With the wei ght of the vehicle on the
road wheels, tighten the stabilizer bar retaining nuts to
the specified torque.
8. REAR WHEEL ALIGNMENT
Specialized equipment is required to measure the
rear wheel alignment. It is therefore recommended
that the vehicle be referred to a specialist suspension
workshop or an authorized dealer for measurement
and adjustment. The suspension components should
be inspected and renewed as necessary prior to having
the wheel alignment checked. If any suspension com-
ponents are renewed, the re ar wheel toe out may be
temporarily adjusted as described below.

TO INSPECT
Examine the tread of the tires. Excessive or
uneven wear will indicate misalignment or damaged
or worn components. Refer to the Tire Wear Trouble
Shooting Chart in the Wheels and Tires section for
possible causes and renew the faulty components.

Badly worn tires should be renewed prior to
having the wheel alignment checked.

TO CHECK AND ADJUST TOE OUT
NOTE: The following procedures are only a
temporary measure. Th e vehicle should be
referred to a specialis t suspension work-
shop or authorized dealer for accurate
measurement and adjustment.

(1) Position the vehicle on a level floor and
bounce the vehicle several tim es to settle the suspen-
sion. (2) Move the vehicle forward approximately 5
meters, with the front wheels straight ahead, to settle
the tires and suspension to the normal running
position.
(3) Place a chalk line across both tire treads at a
point equivalent to the stub axle height and to the rear
of the suspension. Place a vertical mark at the chalk line in the
centre of each tire.

(4) Using a telescopic gauge or tape measure,
measure the distance between both vertical marks and
record the measurement. (5) Move the vehicle forward until the marks are
to the front of the suspen sion, with the horizontal
marks at the same height as in operation (3). (6) Measure the distance between both vertical
marks. (7) The difference between the two measure-
ments will be the amount of toe out of the rear wheels. (8) If the toe out is not as specified, adjust the
rear control arm cams as follows: (9) Measure the distance between the inner
wheel rim and the adjusting flange on the rear
crossmember. Measure the distance on the other side
of the vehicle in the corresponding positions. (10) If the measurements are equal, loosen the
cam nut and turn the cam bolt to move the rear
control arm half the distance required to bring the
rear wheel toe out to specifications. Repeat this
operation on the other side of the vehicle.
(11) If the measurements obtained in operation
(9) are not equal, proceed as follows:
(a) If the toe out is less than specifications,
decrease the length of the shorter arm.
(b) If the toe out is greater than specifications,
increase the length of the longer arm.
NOTE: The toe out will alter approximately
2 mm with each graduation of the adjusting
cam.
