GENERAL FITTING REMINDERS

INFORMATION GENERAL FITTING REMINDERS
WORKSHOP SAFETY IS YOUR RESPONSIBILITY!
The suggestions, cautions and warnings in the
section are intended to serve as reminders for
trained and experienced mechanics. This manual
is not a course in automotive mechanics or
workshop safety.
Shop equipment, shop environment, and the use
and disposal of solvents, fluids, and chemicals
are subject to government regulations which are
intended to provide a level of safety. It is your
responsibility to know and comply with such
regulations.
PRECAUTIONS AGAINST DAMAGE
1.Always fit covers to protect fenders before
commencing work in engine compartment.
2.Cover seats and carpets, wear clean overalls
and wash hands or wear gloves before working
inside vehicle.
3.Avoid spilling hydraulic fluid or battery acid on
paint work. Wash off with water immediately if
this occurs. Use Polythene sheets to protect
carpets and seats.
4.Always use a recommended Service Tool, or a
satisfactory equivalent, where specified.
5.Protect temporarily exposed screw threads by
replacing nuts or fitting plastic caps.SAFETY PRECAUTIONS
1.Whenever possible use a lift or pit when working
beneath vehicle, in preference to jacking. Chock
wheels as well as applying parking brake.
WARNING: Do not use a pit when
removing fuel system components.
2.Never rely on a jack alone to support vehicle.
Use axle stands carefully placed at jacking
points to provide rigid support.
3.Ensure that a suitable form of fire extinguisher is
conveniently located.
4.Check that any lifting equipment used has
adequate capacity and is fully serviceable.
5.Disconnect battery negative lead.
WARNING: Do not disconnect any pipes in
air conditioning refrigeration system,
unless trained and instructed to do so. A
refrigerant is used which can cause blindness if
allowed to contact eyes.
6.Ensure that adequate ventilation is provided
when volatile degreasing agents are being used.
7.Do not apply heat in an attempt to free stiff nuts
or fittings; as well as causing damage to
protective coatings, there is a risk of damage to
electronic equipment and brake linings from
stray heat.

INFORMATION PREPARATION
1.Before removing a component, clean it and its
surrounding areas as thoroughly as possible.
2.Blank off any openings exposed by component
removal, using greaseproof paper and masking
tape.
3.Immediately seal fuel, oil or hydraulic lines when
separated, using plastic caps or plugs, to
prevent loss of fluid and entry of dirt.
4.Close open ends of oilways, exposed by
component removal, with tapered hardwood
plugs or readily visible plastic plugs.
5.Immediately a component is removed, place it in
a suitable container; use a separate container for
each component and its associated parts.
6.Before dismantling a component, clean it
thoroughly with a recommended cleaning agent;
check that agent is suitable for all materials of
component.
7.Clean bench and provide marking materials,
labels, containers and locking wire before
dismantling a component.
DISMANTLING
1.Observe scrupulous cleanliness when
dismantling components, particularly when
brake, fuel or hydraulic system parts are being
worked on. A particle of dirt or a cloth fragment
could cause a dangerous malfunction if trapped
in these systems.
2.Blow out all tapped holes, crevices, oilways and
fluid passages with an air line. Ensure that any
O-rings used for sealing are correctly replaced or
renewed, if disturbed.
3.Use marking ink to identify mating parts, to
ensure correct reassembly. If a centre punch or
scriber is used they may initiate cracks or
distortion of components.
4.Wire together mating parts where necessary to
prevent accidental interchange (e.g. roller
bearing components).
5.Wire labels on to all parts which are to be
renewed, and to parts requiring further
inspection before being passed for reassembly;
place these parts in separate containers from
those containing parts for rebuild.
6.Do not discard a part due for renewal until after
comparing it with a new part, to ensure that its
correct replacement has been obtained.INSPECTION-GENERAL
1.Never inspect a component for wear or
dimensional check unless it is absolutely clean;
a slight smear of grease can conceal an incipient
failure.
2.When a component is to be checked
dimensionally against figures quoted for it, use
correct equipment (surface plates, micrometers,
dial gauges, etc.) in serviceable condition.
Makeshift checking equipment can be
dangerous.
3.Reject a component if its dimensions are outside
limits quoted, or if damage is apparent. A part
may, however, be refitted if its critical dimension
is exactly limit size, and is otherwise satisfactory.
4.Use 'Plastigauge' 12 Type PG-1 for checking
bearing surface clearances. Directions for its
use, and a scale giving bearing clearances in
0,0025 mm steps are provided with it.

INFORMATION FUEL SYSTEM HOSES
CAUTION: All fuel hoses are made up of
two laminations, an armoured rubber outer
sleeve and an inner viton core. If any of
the fuel system hoses have been disconnected, it
is imperative that the internal bore is inspected to
ensure that the viton lining has not become
separated from the amoured outer sleeve. A new
hose must be fitted if separation is evident.
METRIC BOLT IDENTIFICATION
1.An ISO metric bolt or screw, made of steel and
larger than 6 mm in diameter can be identified by
either of the symbols ISO M or M embossed or
indented on top of the head.
2.In addition to marks to identify the manufacture,
the head is also marked with symbols to indicate
the strength grade, e.g. 8.8, 12.9 or 14.9, where
the first figure gives the minimum tensile
strength of the bolt material in tens of kgf/mm
2.
3.Zinc plated ISO metric bolts and nuts are
chromate passivated, a gold-bronze colour.
METRIC NUT IDENTIFICATION
1.A nut with an ISO metric thread is marked on
one face or on one of the flats of the hexagon
with the strength grade symbol 8, 12 or 14.
Some nuts with a strength 4, 5 or 6 are also
marked and some have the metric symbol M on
the flat opposite the strength grade marking.
2.A clock face system is used as an alternative
method of indicating the strength grade. The
external chamfers or a face of the nut is marked
in a position relative to the appropriate hour
mark on a clock face to indicate the strength
grade.
3.A dot is used to locate the 12 o'clock position
and a dash to indicate the strength grade. If the
grade is above 12, two dots identify the 12
o'clock position.
KEYS AND KEYWAYS
1.Remove burrs from edges of keyways with a fine
file and clean thoroughly before attempting to
refit key.
2.Clean and inspect key closely; keys are suitable
for refitting only if indistinguishable from new, as
any indentation may indicate the onset of wear.
TAB WASHERS
1.Fit new washers in all places where they are
used. Always fit a new tab washer.
2.Ensure that the new tab washer is of the same
design as that replaced.

LUBRICATION PRACTICE
Use a high quality oil of the correct viscosity range and service classification in the engine during maintenance and
when topping up. The use of oil not to the correct specification can lead to high oil and fuel consumption and
ultimately to damaged components.
Oil to the correct specification contains additives which disperse the corrosive acids formed by combustion and
prevent the formation of sludge which can block the oilways. Additional oil additives should not be used. Always
adhere to the recommended servicing intervals.
WARNING: Many liquids and other substances used in motor vehicles are poisonous. They must
not be consumed and must be kept away from open wounds. These substances, among others,
include anti-freeze windscreen washer additives, lubricants and various adhesives.

FUEL REQUIREMENTS
Catalyst vehicles
Vehicles equipped with catalytic converter are designed to use ONLY unleaded fuel. Unleaded fuel must be used
for the emission control system to operate properly. Its use will also reduce spark plug fouling, exhaust system
corrosion and engine oil deterioration.
Using fuel that contains lead will result in damage to the emission control system and could result in loss of
warranty coverage. The effectiveness of the catalysts in the catalytic converters will be seriously impaired if leaded
fuel is used. The vehicle is equipped with an electronic fuel injection system, which includes two oxygen sensors.
Leaded fuel will damage the sensors, and will deteriorate the emission control system.
Regulations require that pumps delivering unleaded fuel be labelledUNLEADED.Only these pumps have nozzles
which fit the filler neck of the vehicle fuel tank.
