VEHICLE IDENTIFICATION AND GENERAL SPECIFICATIONS

1. VEHICLE IDENTIFICATION
When purchasing spare parts or when
registering
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.

10 General Information

If tools are to be stored for any length of time, it is
good policy to wipe them with an oily cloth.

Bladed screwdrivers should be checked for dam-
age to the tip. If necessary, the tip can be returned to
its original profile by careful grinding. Do not grind
screwdriver tips to a sharp point.

Hammer heads should be secure on their handles
and should be regularly checked for cracking or other
damage.

Chisels and punches should be checked for dam-
age or 'mushrooming' of the head. Any faults should
be rectified by grinding.

Hydraulic jacks should be regularly checked for
fluid leaks. Chassis stands and car ramps should be
checked for damage and cracks. Any equipment that
is suspect should not be used.

STORES
For routine maintenance, stores of automotive
oils, greases and additives should be kept on hand.
The following is a suggested list.

Engine oil.
Brake fluid.
Manual transmission or automatic transmission
oil — automatic transmission oil is also used in
the power steering system.
Rear axle oil.
Cooling system corrosion inhibitor/antifreeze.
Chassis grease.
High melting point grease, for hub bearings etc.
Penetrating oil or spray.
Kerosene or similar cleaning solvent.
Methylated spirits.

Oils and greases are available in handy pack size for
do-it-yourself lube jobs.
2. SAFETY
PERSONAL SAFETY
Safety when working on a motor vehicle is basical-
ly a matter of commonsense. Some safety precautions
to prevent personal in juries are as follows.

Raising a Vehicle
Always jack a vehicle on firm, level ground and at
the specified jacking points . Ensure that the wheels
remaining on the ground are fully chocked.

After raising the vehicle, place chassis stands
underneath and allow the weight of the vehicle to rest
on them. Do not use bricks, blocks of wood or similar
material.

NOTE: Never work under a vehicle which is
only supported by a jack.

Electrical System
Always disconnect the negative battery terminal
when working on any electrical components. Avoid
wearing metal watches, rings and chains which may
short across live terminals.

As battery gases are explosive, keep naked flames
and sparks clear of the work area. When connecting
and disconnecting jumper leads, use extreme caution
to avoid sparking.

Electronic Ignition Systems
Electronic ignition systems produce dangerous
high tension voltages in bo th the primary and second-
ary circuits which can be fatal. Exercise extreme
caution when working on or near any ignition system
components. Do not disconnect high tension leads
while the engine is running.

Work Area
Do not run the engine in a confined space. Ensure
that the work area is adequately ventilated.

Spilt oil or water should be cleaned immediately
to avoid the possibility of slipping.

Fuel System
Always disconnect the negative battery terminal
when working on any fuel components. Do not smoke.
Keep naked flames and sparks clear of the work area.

Do not siphon fuel using the mouth. Use a hand
pump or suitable siphon.

Do not attempt to repair a fuel tank by welding it.
This is an extremely hazardous procedure and should
be entrusted to a specialist.

Cooling System
To avoid scalding, use caution when releasing the
radiator cap on an engine wh ich is at normal operating
temperature. Turn the cap anti-clockwise to the first
stop and allow any pressure in the system to release.
When the pressure is released, remove the cap from
the radiator.

Brakes
As asbestos is used in some brake lining material,
avoid inhaling brake dust. Do not use compressed air
to remove the dust. Gentle brushing with a small
brush or using a vacuum cleaner with a hose attach-
ment are the safest methods of cleaning the brakes.
The above precautions also apply to the clutch plate
lining material.

24 Wheels and Tires


When the tire tread groove depth is less than 1.5
mm, or when the tire is worn to the point where the
tire wear indicators are level with the tread surface,
the tire should be renewed.
To preserve tire life it is good policy to periodi-
cally have the front wheels balanced and the front end
alignment checked on a reliable wheel alignment
machine.

The wheel and tire assemblies may be rotated at
20 000 km if desired. Rotation of the wheels and tires
will increase the period between tire renewal. Radial
tires should not be cross changed, they should be
changed from front to rear on the same side.


Tire rotation diagram. If desired, the wheel and tire
assemblies may be rotated every 20 000 km in the
manner shown. Vector SSS tire rotation not to include
spare wheel.
The air pressure in the tire is probably the single
most important aspect of tire care. Too little or too
much pressure in the tire can cause rapid wear or
complete failure through overheating. Where possible
the tire pressures should be checked and adjusted
when the tires are cold.

As a rule, different tire types, tread patterns or
sizes should never be used on the vehicle at one time.
All the tires on the vehicles, including the spare
should be a matched set to prevent the vehicle
behaving erratically under certain conditions. Under
no circumstances mix radial ply and conventional ply
tires.

40 Engine


Check the engine oil for level and dilution on the dipstick.
dosed. Before dismantling the engine to
inspect the big ends check the engine oil for
correct level and dilution on the dipstick.
Also, remove the oil pressure sender unit
and connect an oil pressure gauge into the
oil gallery to check the oil pressure readings.

MAIN BEARING NOISE (APPARENT)
(1) Loose flywheel: Tighten the flywheel securing
bolls to the specified torque. (2) Low oil pressure: Check the bearing to
journal clearance. Check the condition of the oil
pump and pressure relief valve. Recondition the oil
pump as necessary. (3) Excessive crankshaft end float: Renew the
main bearings. (4) Crankshaft journals out of round and exces-
sive bearing to journal clear ance: Regrind the journals
and renew the bearings (undersize).
(5) Insufficient oil supply: Replenish the oil in
the sump to the correct level.
NOTE: Main bearing noise is indicated by a
heavy but dull knock when the engine is
under load. A loose flywheel is indicated by
a thud or dull click when the ignition is
turned off. It is us ually accompanied by
vibration.

Crankshaft end float noise is indicated by
a sharp rap at idle speed. The crankshaft
can be readily checked for excessive end
float by levering the crankshaft backwards
and forwards.

If the oil pressure is not satisfactory,
remove the main bearing caps and assess
the bearing clearance using the Plastigage
method as described in this section. Ovality
and wear on the main bearing journals can
only be checked with a micrometer after the
crankshaft has been removed.

EXCESSIVE OIL CONSUMPTION
(1) Oil leaks: Check and renew the engine gas-
kets or seals as necessary.
(2) Damaged or worn valve stem oil seals:
Dismantle the cylinder head and renew the damaged
or worn oil seals. (3) Excessive valve stem to valve guide clear-
ance: Ream the valve guides and renew the valves as
necessary. (4) Worn or broken piston rings: Renew the
piston rings on all pistons. (5) Rings too tight or stuck in the grooves:
Renew the rings and clean the ring grooves.
(6) Excessive wear in the cylinders, pistons and
rings: Recondition the cylinders and renew the pistons
and rings. (7) Compression rings incorrectly installed. Oil
rings clogged or broken: Renew the piston rings.
NOTE: Before checking the engine for oil
leaks the engine should be completely de-
greased and cleaned. Run the engine at
operating temperature for a period and
visually check for oil leakage. By placing
white paper on the floor directly beneath the
engine any excessive leak can be readily
pinpointed.

Damaged or worn valve stem oil seals
which allow oil to be drawn down past the
valve stems into the combustion chambers
can be diagnosed by allowing the engine to
idle for a few minutes and then opening the
throttle. If oil is being drawn past the valve
stems a heavy discharge of blue smoke will
be seen at the tailpipe.

Piston, ring and cylinder bore troubles are
normally accompanied by a loss of compres-
sion. Cylinder compression can only be
accurately assessed by using a compression
gauge.

Run the engine over white paper to check for oil leaks.

Engine


Main bearing cap removed showing the location of the rear seal and sealant grooves.
until the sealant appears at the inner, lower edge of the
bearing cap to cylinder block joint. Install the bearing
cap bolts and tighten to the specified torque.

(5) Tighten the remaining main bearing cap
bolts and the connecting rod cap bolts to their
respective tensions and rotate the crankshaft to check
for binding. (6) Install the crankshaft oil seal to the end of the
crankshaft after applying lithium grease to the lip of
the oil seal. Ensure that the l i p of the seal is facing
towards the engine.
(7) Install the remainder of the engine compo-
nents by referring to the relevant headings in this
section.
TO RENEW MAIN BEARINGS -
CRANKSHAFT INSTALLED

(1) Remove the automatic transaxle or manual
transaxle as described in the appropriate section.

(2) Remove the flywheel/drive plate as outlined
under the Flywheel/Drive Plate heading. (3) Remove the engine sump and oil pump
pickup pipe as previously described. (4) Ensure that the main bearing caps are num-
bered to ensure correct assembly. (5) Remove the main bearing cap bolts and
remove the bearing cap and half shell of the bearing to
be renewed. Thoroughly clean the bearing cap in
solvent. (6) Where necessary, use the Plastigage method
to measure the bearing clearance.
(7) Position a piece of Plastigage the approxi-
mate length of the bearing width, across the bearing
shell in the cap and tigh ten the cap bolts to the
specified torque. Do not rotate the crankshaft. (8) Remove the bearing cap and measure the
spread width of the Plastigage with the scale on the
packet to determine the main bearing clearance.
Compare the measurement to the Specifications and if
the bearing clearance exceeds the limit, install a new
set of bearing shells.
NOTE: Renew one bearing at a time, leav-
ing the others securely attached.

(9) Install a brass rivet in the crankshaft journal
oil drilling and rotate the crankshaft in a clockwise
direction until the head of the rivet contacts the plain
edge of the upper bearing shell. (10) Continue to rotate the crankshaft to carry
the upper half of the bearing shell out of the crank-
case.
(11) Select a half shell of the required thickness
(standard or undersize), coat it liberally with clean
engine oil and start it, plai n edge first, into position on
the crankshaft. Rotate the crankshaft anti-clockwise so
that the rivet contacts the locating lug edge of the
bearing shell, carrying it into position in the crankcase
above the main bearing journal. Slightly reverse the
rotation of the crankshaft and remove the rivet from
the oil drilling in the crankshaft. (12) Place the other half shell of the selected
bearing shells in the bear ing cap. checking the clear-
ance as detailed in operations (7) and (8).
NOTE: By checking the taper on the plas-
tigage any taper of the bearing journal can
be calculated.

(13) When the bearing has been correctly selected
to give the specified clearance, tighten the cap bolts to
the specified torque. (14) Use the same method to renew the other
main bearings. (15) When renewing the rear main bearings, re-
move and discard the rear crankshaft oil seal. (16) Install the rear main bearing cap into position
and inject KP510-00150 sealant or equivalent into the
grooves in the sides of the rear bearing cap. Fill the
grooves until the sealant a ppears at the inner lower
View showing the numbering and correct location of
the main bearing caps.
