precaution warnings given on material
containers (labels) and in any accompanying
leaflets, posters or other instructions. Material
health and safety data sheets can be obtained
from manufacturers.
- Do remove chemical materials from the skin
and clothing as soon as practicable after soiling.
Change heavily soiled clothing and have it
cleaned.
- Do organize work practices and protective
clothing to avoid soiling of the skin and eyes;
breathing vapors, aerosols, dusts or fumes;
inadequate container labeling; fire and explosion
hazards.
- Do wash before job breaks, before eating,
smoking, drinking or using toilet facilities when
handling chemical materials.
- Do keep work areas clean, uncluttered and free
of spills.
- Do store chemical materials according to
national and local regulations.
- Do keep chemical materials out of the reach of
( ' children.
- Do not clean hands or clothing with chemicals.
Chemicals, particularly solvents and fuels, will
dry the skin and may cause irritation leading to
dermatitis or be absorbed through the skin in
toxic or harmful quantities.
- Do not use emptied containers for other
materials except when they have been cleaned
under supervised conditions.
- Do not sniff or smell chemical materials. Brief
exposure to high concentrations of fumes can
be toxic or harmful.
Chlorofluorocarbons (CFC)
There is concern in the scientific community that
CFCs and Halons are depleting the upper ozone
layer which filters out harmful ultraviolet radiation.
Decreased filtration of ultraviolet radiation may
result in increases in skin cancer, cataracts and
immune system suppression in humans, as well
as decreased productivity of crops and aquatic
systems.
CFCs are used primarily as refrigerants in vehicle
air conditioning systems and as aerosol
propellants. Halons are used as fire extinguishants.
Clutch Fluids
Chemical Materials - Do Nots
See Brake fluids.
- Do not mix chemical materials except under the
manufacturers instructions; some chemicals can
form other toxic or harmful chemicals, give off
toxic or harmful fumes or become explosive
when mixed together.
- Do not spray chemical materials, particularly
those based on solvents, in confined spaces,
for example when people are inside a vehicle.
- Do not apply heat or flame to chemical materials
except under the manufacturers instructions. Some are highly flammable and some may
release toxic or harmful fumes.
- Do not leave containers open. Fumes given off
can build up to toxic, harmful or explosive
concentrations. Some fumes are heavier than
air and will accumulate in confined areas such
as pits.
- Do not transfer chemical materials to unlabelled
containers.

Welding processes include Resistance Welding
(Spot Welding), Arc Welding and Gas Welding.
See Corrosion Protection.
Resistance Welding
Viton
In common with many other manufacturers
vehicles, some components have O-rings, seals
or gaskets, which contain a material known as
'Viton'.
Viton is a fluoroelastomer, that is a synthetic rubber
type material, which contains Fluorine. It is
commonly used for O-rings, gaskets and seals of
all types. Although Viton is the most well known
fluoroelastomer, there are others, including
Fluorel
and Tecmoflon.
When used under design conditions
fluoroelastomers are perfectly safe. If, however,
they are exposed to temperatures in excess of
400°C, the material will not burn, but will
decompose, and one of the products formed is
hydrofluoric acid.
This acid is extremely corrosive and may be
absorbed directly, through contact, into the general
body system.
O-rings, seals or gaskets which have been exposed
to very high temperatures will appear charred or
as a black sticky substance.
DO NOT; under any circumstances touch them or
the attached components.
Enquiries should be made to determine whether
Viton or any other fluoroelastomer has been used
in the affected O-ring, seal or gasket. If they are of
natural rubber or
nitrile there is no hazard. If in
doubt, be cautious, as the material may be Viton
or any fluoroelastomer.
If Viton or any other fluoroelastomers have been
used, the affected area should be decontaminated
before the commencement of work.
Disposable heavy duty plastic gloves should be
worn at all times, and the affected area washed
down using wire wool and a limewater (calcium
hydroxide) solution to neutralize the acid before
disposing of the decomposed Viton residue and
final cleaning of the area. After use, the plastic
gloves should be discarded carefully and safely. This process may cause particles of molten metal
to
be emitted at a high velocity, and the eyes and
skin must be protected.
Arc Welding
This process emits a high level of ultra-violet radiation, which may cause arc-eye, and skin burns
to the operator and to other persons nearby.
Gas-shielded welding processes are particularly
hazardous in this respect. Personal protection must
be worn, and screens used to shield other
~eo~le. . .
CONTACT LENS WEARERS ARE ADVISED TO
REVERT TO ORDINARY SPECTACLES WHEN
ARC WELDING as the arc spectrum is believed to
emit microwaves which dry out the fluid between
the lens and the eye. This may result in blindness
when the lens is removed from the eve.
Metal spatter will also occur, and appropriate eye
and skin protection is necessary.
The heat of the welding arc will produce fumes and
gases from the metals being welded, the rods and
from any applied coatings or contamination on the
surfaces being worked on. These gases and fumes
may be toxic and inhalation of these should be
avoided. The use of extraction ventilation to remove
the fumes from the working area may be necessary
particularly in cases where the general ventilation
is poor, or where considerable welding work is
anticipated. In extreme cases or confined spaces
where adequate ventilation cannot be provided,
air-fed respirators may be necessary.
Gas Welding (and Cutting)
Oxy-acetylene torches may be used for welding
and cutting, and special care must be taken to
prevent leakage of these gases, with consequent
risk of fire and explosion.

The process will produce metal spatter and eye "
and skin protection is necessary.

DESCRIPTION AND OPERATION
RoadIRoller Testing
I Road or roller testing may be carried out for various
reasons and a procedure detailing pre-test checks,
engine starting and stopping, pre-driving checks,
on-test checks and final checks to be completed
on completion of the test is given below.
Unless complete vehicle performance is being
checked, the full road test procedure need not be
carried out. Instead, those items particularly
relevant to the
system(s) being checked can be
extracted.
Pre-Test Checks
A WARNING:lf the brake system hydraulic
fluid level is low, pedal travel is excessive
or a hydraulic leak is found, do not attempt
to road test the vehicle until the reason for
the low fluid level, excessive pedal travel
or hydraulic leak is found and rectified.
It is suggested that pre-test checks and functional
tests of those systems and circuits which affect the
safe and legal operations of the vehicle, such as
( , brakes, lights and steering, should always be
carried out before the road or roller test.
With the ignition switched off, check:
- the engine oil level.
- the engine coolant level.
- the tires, for correct pressure, compatible types
and tread patterns, and wear within limits.
- that there is sufficient fuel in the tank to
complete the test.
- all around the engine, transmission and under
the vehicle for oil, coolant, hydraulic and fuel
leaks. Make a note of any apparent leaks and
wipe off the surrounding areas to make it easier
to identify the extent of the leak on completion
of the test.
Starting the Engine
N0TE:On initial drive away from cold and within
the first 1.5 km (1 mile), do not depress the
accelerator pedal beyond half travel until the
vehicle has attained a minimum speed of
25 kmlh
(15 mileslh). Never operate at high engine speed
or with the accelerator pedal at full travel whilst the
engine is cold.
With the ignition switched off, check:
- that the parking brake is applied.
- that the gear lever is in the neutral position.
- that all instrument gauges (except fuel gauge)
read zero.
With the ignition switched on, check:
- that the ignition controlled warning lamps are
illuminated.
- that the engine temperature gauge registers a reading compatible with the engine temperature.
- that the fuel gauge registers a reading
appropriate to the fuel level in the tank.
- the operation of the parking brake warning lamp
and fluid level warning indicator.
Road or Roller Testing
A CAUTI0N:lf road testing, check the brake
operation while still traveling at low speed
before continuing with the test. If the
brakes pull to one side, or appear to be
otherwise faulty, do not continue with the
road test until the fault has been found and
rectified.
During the road or roller test, check:
- that the clutch pedal operation is not stiff or
heavy.
- that the initial gear engagement is smooth and
there is no evidence of clutch drag.
- that the parking brake control operates smoothly
and releases quickly and completely.
- that the clutch takes up the drive smoothly,
without slip or judder.
- that gear changing is smooth with no abnormal
noises or vibrations from the transmission.
- the engine power output is satisfactory, full
power is achieved, acceleration is smooth and
pedal operation is not stiff or heavy, and engine
speed returns to idle correctly.
- there is no excessive or abnormally colored
smoke from the engine under normal driving,
heavy load or overrun conditions.
- that steering operation, including power steering
(if equipped), is smooth, accurate, not
excessively heavy or with excessive free play
or vibration.
- that the steering does not pull to one side and
self centers smoothly after cornering.

100-04-5 Noise, Vibration and Harshness 100-04-5
DIAGNOSIS AND TESTING
Noise Conditions
Gear noise is typically a howling or whining due
to gear damage or incorrect bearing preload. It
can occur at various speeds and driving
conditions, or it can be continuous.
Chuckle is a particular rattling noise that sounds
like a stick against the spokes of a spinning
bicycle wheel. It occurs while decelerating from
64
kmlh (40 mph) and can usually be heard all
the way to a stop. The frequency varies with
vehicle speed.
Knock is very similar to chuckle, though it may
be louder and occurs on acceleration or
deceleration. The
teardown will disclose what
has to be corrected.
Clicking, popping or grinding noises may be caused
by the following:
worn, damaged or incorrectly installed wheel
bearing, suspension or brake component.
Check and rule out tires, exhaust and trim items
before disassembling the transmission to diagnose
and correct gear noise.
The noises described under Road Test usually
( have specific causes that can be diagnosed by
observation as the unit is disassembled. The initial
clues are the type of noise heard on the road test
and driving conditions.
Vibration Conditions
Vibration at highway speeds may be caused by
the following:
out-of-balance front or rear wheels.
out-of-round tires.
Shudder or vibration during acceleration may be
caused by the following:
damaged powertrainldrivetrain mounts.
excessively high constant velocity (CV) joint
operating angles caused by incorrect ride height.
Check ride height, verify correct spring rate and
check items under inoperative conditions.
Road Test
I A gear-driven unit will produce a certain amount
of noise. Some noise is acceptable and may be
audible at certain speeds or under various driving conditions,
as on a newly paved asphalt road. The
slight noise is in no way detrimental and must be
considered normal.
The road test and customer interview (if available)
provide information needed to identify the condition
-
and give direction to the correct starting point for
diagnosis.
1. Make notes throughout the diagnosis routine.
Make sure to write down even the smallest bit
of information, because it may turn out to be the
most important.
2. Do not touch anything until a road test and a
thorough visual inspection of the vehicle have been carried out. Leave the tire pressures and
vehicle load just where they were when the
condition was first observed. Adjusting tire
pressures, vehicle load or making other
adjustments may reduce the
condition(s)
intensity to a point where it cannot be identified
clearly. It may also inject something new into
the system, preventing correct diagnosis.
3. Make a visual inspection as part of the
preliminary diagnosis routine, writing down
anything that does not look right. Note tire
pressures, but do not adjust them yet. Note
leaking fluids, loose nuts and bolts, or bright
spots where components may be rubbing
against each other. Check the load space for
unusual loads.
4. Road test the vehicle and define the condition
by reproducing it several times during the road
test.
5. Carry out the Road Test Quick Checks as soon
as the condition is reproduced. This will identify
the correct diagnostic procedure. Carry out the
Road Test Quick Checks more than once to
verify they are providing a valid result.
Remember, the Road Test Quick Checks may
not tell where the concern is, but they will tell
where it is not.
Road Test Quick Checks
1. 24-80 kmlh (1 5-50 mph): with light acceleration,
a moaning noise is heard and possibly a
vibration felt in the front floor panel. It is usually
worse at a particular engine speed and at a
particular throttle setting during acceleration at
that speed. It may also produce a moaning
sound, depending on what component is
causing it. REFER to Tip-in Moan in the
Driveline Noise and Vibration Symptom Chart.

206-00-3 Brake System - General Information 206-00-3
DIAGNOSIS AND TESTING
Brake System
The brakes system operates by transferring effort
applied to the brake pedal by the driver to the
brakes at each wheel.
The braking effort is distributed to each wheel,
using a hydraulic system. The system is assisted
using a vacuum brake booster that reduces pedal
effort and increases hydraulic pressure.
The parking brake operates on the rear wheels
and is applied using a hand operated control.
lnspection and Verification
N0TE:Before carrying out any diagnosis, make
sure that the brake system warning indicator is
functional.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical
damage.
3. If an obvious cause for an observed or reported
concern is found, correct the case (if possible)
before proceeding to the next step.
4. If the cause if not visually evident, verify the
symptom and refer to the Symptom Chart.
Visual lnspection Chart
Road Test
1.
Perform a road test to compare actual vehicle
braking performance with the performance
standards expected by the driver. The ability of the
test driver to make valid comparisons and detect
performance deficiencies will depend on
experience.
Mechanical
- Tire pressure
- Wheels and tires
- Fluid leak from brake line(s)
The driver should have a thorough knowledge of
the brake system operation and accepted general
performance guidelines to make good comparisons
, and detect performance concerns.
An experienced technician will always establish a
route that will be used for all brake diagnosis road
tests. The road selected will be reasonably smooth and level. Gravel
or bumpy roads are not suitable
because the surface does not allow the tires to grip
the road equally. Crowned roads should be avoided
because of the large amount of weight shifted to
the low set of wheels on this type of road. Once
the route is established and consistently used, the
road surface variable can be eliminated from the
test results.
Before a road test, get a complete description of
the customer concerns or suspected condition.
From the description, the technician will be able to
match possible causes with symptoms. Certain
components will be identified as possible sources
while others will be eliminated by the evidence.
More importantly, the customer description can
reveal unsafe conditions which should be checked
or corrected before a road test. The description will
also help form the basic approach to the road test
by narrowing the concern to specific components,
vehicle speed or conditions.
Begin the road test with a general brake
performance check. Using the description of the
concern, test the brakes at different vehicle speeds
using both light and heavy pedal pressure.
Determine if the concern is in the front or rear
braking system. First use the foot brake and then
the parking brake. If the condition
(i.e. pull,
vibration, pulsation) occurs only on operation of
the parking brake, the concern is in the rear brake
system.
If the condition occurs when the foot brake
is depressed, the concern is in the front brake
system.
Avoid locking the brakes and sliding the tires. This
condition will not indicate brake efficiency. A heavily
braked but turning wheel will stop the vehicle in a
shorter distance than locked wheels.
If the concern becomes evident during this check,
make sure it fits the description given before the
road test. If the concern is not evident, attempt to
duplicate the condition using the information from
the description.
If a concern exists, use the Brake System Symptom
Chart in order to isolate it to a specific sub-system
and condition description. From this description, a
list of possible sources can be used to further
narrow the cause to a specific component or
condition.
