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.

1. HOW TO GREASE AND OIL CHANGE
(1) Run the front of the vehicle onto car ramps
and stop the engine. Chock the front wheels. (2) Raise the rear of the vehicle and place
chassis stands under the rear jacking points.
NOTE: It is best if the vehicle is kept as level
as possible to avoi d false readings when
checking the lubricant levels.



(3) Clean around the engine sump drain plug.
(4) Place a drain tin under the engine sump,
remove the engine sump drain plug and allow the
engine sump to completely drain.
NOTE: It is best to drain the engine sump
with the oil at operating temperature. How-
ever, if the oil is hot take care to avoid
scalding.

(5) Check that the sealing gasket on the sump
plug is in a serviceable condition. (6) When the engine sump has completely
drained, install and firmly tighten the sump drain plug.
Wipe around the plug after installation. (7) Place the drain tin under the oil filler,
remove the oil filter using a filter removal tool and
allow the residual engine oil to drain. Smear the
scaling ring of the new filter with engine oil and
lighten the filter by hand as per the instructions
supplied with the new filter.
NOTE: Before installing the new filter, en-
sure that the sealing gasket from the old
filter has not adhered to the filter sealing
surface on the engine.

(8) Remove the level checking plug from the

Location of the engine sump drain plug.
Removing the engine oil filter using a filter removal tool.

Wheels and Tires 23
(3) Excessive play in the front suspension ball
joints: Check and renew the ball joints.
(4) Excessive play in the hub bearing assembly:
Check and renew the hub bearing assembly.
WORN SPOTS ON CENTRE OF TREAD

(1) Static unbalance of the wheel and tire asem-
bly: Check the balance of the wheel and tire assembly
(2) Radial run out (eccentricity) of the wheel:
Check and renew the wheel.
FEATHERED EDGES ON TREAD PATTERN

(1) Excessive speed when cornering: Revise driv-
ing habits. (2) Excessive toe-in or toe-out: Check and adjust
the wheel alignment.

(3) Bent, loose or worn suspension components:
Check and renew any faulty components.

NOTE: To preserve tire life it is good policy
to periodically have the front wheel balanced
and the steering geometry checked on a
reliable wheel alignment machine.

Under no circumstances mix radial ply
and conventional ply tire s. Install only tires
of the same construction to all four wheels.

3. CARE AND MAINTENANCE
STEEL WHEELS
Steel wheels should be regularly cleaned of all
foreign matter, such as dirt and mud. If foreign matter
is allowed to build up it will affect the balance of the
wheel and may cause vibrations and uneven tire wear.
If the paint has been chipped or scratched it should be
touched up as soon as possible to prevent rust.

Any minor damage to the wheel rim can usually
be repaired using a suitable hammer after the wheel
has been removed from the vehicle. However, any
major rim damage or buckling of the wheel will
necessitate the renewal of the wheel. It is good policy
to occasionally remove the wheels from the vehicle
and inspect them for damage, cracks or corrosion.

ALLOY WHEELS
Alloy wheels should be regularly cleaned of all
foreign matter such as dirt and mud. If foreign matter

Wheels should be cleaned regularly of dirt and mud.
is allowed to build up it will affect the balance of the
wheel and may cause vibrations and uneven tire wear.

The alloy wheels are coated with a clear protective
finish. Do not use abrasive cleaner, polishing com-
pounds, steel wool etc. when cleaning the wheels. Only
mild soap and warm wate r are recommended. Alloy
wheels are particularly su sceptible to corrosion dam-
age particularly if exposed to salt water.

Alloy wheels being relatively soft in comparison to
steel are easily scuffed, however, this will not affect the
serviceability of the wheel. Where heavy damage has
been sustained to the wheel it should be renewed.
Buckling or cracking of an alloy wheel cannot be
repaired.

TYRES
The depth of the tire tread grooves should never
be allowed to be less than 1.5 mm before the tires are
renewed. The tires should also be renewed when any
damage, whether it be internal or external, is evident.
Minor punctures or leaks s hould be properly repaired.
Refer the tire to a tire spec ialist if there is any doubt
about the serviceability of the tire.

The tread, tread grooves and sidewalls should be
regularly inspected for foreign matter i.e. nails, stones
etc. Where foreign matter is detected it should be
removed from the tire and if necessary, the puncture
repaired.

The tire valves should always have the caps
installed, be regularly cleaned of dirt or dust and be
inspected for leakage and damage every time the tire
pressures are checked.

Regularly inspect the tread of the tires for signs of
uneven wear. If uneven wear is apparent, refer to the
heading Tire Wear Trouble Shooting in this section
for possible causes and cures. If the uneven tire wear
is noticed early enough, the cause correctly identified
and the necessary cure carried out, the life of the tire
should be extended.

42 Engine
The cylinder block is a cast iron alloy, deep skirt
design and the crankshaft is supported in the cylinder
block by five precision insert replaceable main bear-
ings. Crankshaft end float is controlled by the flanged
centre main bearing. Connecting rods are I section
forgings equipped with precision insert replaceable big
end bearings. The gudgeon pins are an interference fit
in the connecting rod and a floating fit in the piston.

The cast aluminum pistons are equipped with
two compression rings and one oil control ring.

The twin rotor, involute gear oil pump is mounted
directly to the front face of the cylinder block. The
inner rotor is internally driven by the crankshaft. The
oil pump pressure relief valve is not adjustable, and
consists of a plunger and spring mounted in the oil
pump body.

The pump draws oil through a screen in the sump
and delivers it, via a full flow replaceable oil filter, to
the oil gallery from where it is distributed to the
hydraulic tappets, camshaft and crankshaft bearings
and to the overhead rocker and valve mechanism.
