DESCRIPTION AND OPERATION
Two Pack
Can also contain harmful and toxic unreacted
resins and resin hardening agents. The
manufacturers instructions should be followed. See
also Resin-based Adhesives and
Isocyanate
Adhesives and Sealers under Adhesives and
Sealers.
Spraying should preferably be carried out in
exhausted ventilated booths removing vapor and
spray mists from the breathing zone. Individuals
working in booths should wear appropriate
respiratory protection. Those doing small-scale
repair work in the open workshop should wear
air-fed respirators.
Pressurized Equipment
See High Pressure Air, Lubrication and Oil Test
Equipment.
Solder
Solders are mixtures of metals such that the
melting point of the mixture is below that of the
constituent metals (normally lead and tin). Solder
application does not normally give rise to toxic lead
fumes, provided a
gaslair flame is used.
Oxy-acetylene flames should not be used, as they
are much hotter and will cause lead fumes to be
produced.
Some fumes may be produced by the application
of any flame to surfaces coated with grease, and
inhalation of these should be avoided.
Removal of excess solder should be undertaken
with care, to make sure that fine lead dust is not
produced, which can give toxic effects if inhaled.
Respiratory protection may be necessary.
Solder spillage and filings should be collected and
removed promptly to prevent general air
contamination by lead.
High standards of personal hygiene are necessary
in order to avoid ingestion of lead or inhalation of
solder dust from clothing.
Solvents
See also Chemical Materials, Fuels (Kerosene),
Fire.
For example acetone, white spirit, toluene, xylene,
trichloroethane.
2006.0 Fiesta 1212006
Used in cleaning and dewaxing materials, paints,
plastics, resins and thinners.
Some may be highly flammable or flammable.
Skin contact will degrease the skin and may result
in irritation and dermatitis following repeated or
prolonged contact. Some can be absorbed through
the skin in toxic or harmful quantities.
Splashes in the eye may cause severe irritation
and could lead to loss of vision.
Brief exposure of high concentrations of vapors or
mists will cause eye and throat irritation,
drowsiness, dizziness, headaches and, in the worst
circumstances, unconsciousness.
Repeated or prolonged exposure to excessive but
lower concentrations of vapors or mists, for which
there might not be adequate warning indications,
can cause more serious toxic or harmful effects.
Aspiration into the lungs, for example through
vomiting, is the most serious consequence of
swallowing.
Avoid splashes to the skin, eyes and clothing. Wear
protective gloves, goggles and clothing if
necessary.
Make sure there is good ventilation when in use,
avoid breathing fumes, vapors and spray mists and
keep containers tightly sealed. Do not use in
confined spaces.
When spraying materials containing solvents, for
example paints, adhesive, coatings, use extraction
ventilation or personal respiratory protection in the
absence of adequate general ventilation.
Do not apply heat or flame except under specific
and detailed manufacturers instructions.
Sound Insulation
See Fibre Insulation, Foams.
Suspended Loads
A CAUTI0N:Never improvise lifting tackle.
There is always a danger when loads are lifted or
suspended. Never work under an unsupported,
suspended or raised load, for example a
suspended engine.
Always make sure that lifting equipment such as
jacks, hoists, axle stands and slings are adequate
and suitable for the job, in good condition and
regularly maintained.

DESCRIPTION AND OPERATION
Transmission Brake Bands
See Asbestos.
Underseal Welding
See
also Fire, Electric Shock, Gas Cylinders. (
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.

DIAGNOSIS AND TESTING
2. AccelerationIDeceleration: With slow
acceleration and deceleration, a shake is
sometimes noticed in the steering
wheellcolumn,
seats, front floor panel, front door trim panel or
front end sheet metal. It is a low frequency
vibration (around
9-1 5 cycles per second). It
may or may not be increased by applying the
brakes lightly. REFER to
Idle
BoomIShakeNibration in the Driveline Noise
and Vibration Symptom Chart.
High Speed: A vibration is felt in the front floor
panel or seats with no visible shake, but with
an accompanying sound or rumble, buzz, hum,
drone or booming noise. Coast with the clutch
pedal depressed (manual transmission) or shift
control selector lever in "N" (NEUTRAL)
(automatic transmission) and engine idling. If
vibration is still evident, it may be related to
wheels, tires, front brake discs, wheel hubs or
front wheel bearings. REFER to Shake and
Vibration While Driving in the Driveline Noise
and Vibration Symptom Chart.
4. Engine rpm Sensitive: A vibration is felt
whenever the engine reaches a particular rpm.
It will disappear in neutral coasts. The vibration
can be duplicated by operating the engine at
the problem rpm while the vehicle is stationary.
It can be caused by any component, from the
accessory drive belt to the clutch or torque
converter which turns at engine speed when the
vehicle is stopped. REFER to Shake and
Vibration While Driving in the Driveline Noise
and Vibration Symptom Chart.
5. Noise and Vibration While Turning: Clicking,
popping or grinding noises may be due to the
following:
worn, damaged or incorrectly installed front
wheel bearing.
damaged
powertrainldrivetrain mounts.
Road Conditions
An experienced technician will always establish a
route that will be used for all NVH diagnosis road
tests. The road selected should be reasonably
smooth, level and free of undulations (unless a
particular condition needs to be identified). A
smooth asphalt road that allows driving over a
range of speeds is best. Gravel or bumpy roads
are unsuitable because of the additional road noise produced.
Once the route is established and
consistently used, the road noise variable is
eliminated from the test results.
N0TE:Some concerns may be apparent only on
smooth asphalt roads.
If a customer complains of a noise or vibration on
a particular road and only on a particular road, the
source of the concern may be the road surface. If
possible, try to test the vehicle on the same type
of road.
Vehicle Preparation
Carry out a thorough visual inspection of the
vehicle before carrying out the road test. Note
anything which is unusual. Do not repair or adjust
any condition until the road test is carried out,
unless the vehicle is inoperative or the condition
could pose a hazard to the technician. After
verifying that the condition has been corrected,
make sure all components removed have been
installed.
Power Steering Conditions
c !
Check for the noise in the following conditions to
verify the customer concern.
Check for the noise in several temperature
conditions.
Is the noise from when the vehicle was new?
Can the noise be repeated constantly or is it
random?
Check the condition of the vehicle age, mileage
and service record.
Interview the customer to find the operating
condition in which the noise will occur. Test the
vehicle based on the
detail(s) from the customer
interview.
Follow the power steering operation noise
condition tables below, to find which condition
the noise will occur.
Power Steering Operation Noise Check
Step 1 : Check for NVH concerns from non-steering
components, which may sound like noises coming
from the steering system.
