DESCRIPTION AND OPERATION
Do not use damaged or defective tools or
equipment, particularly high-speed equipment such
i as grinding wheels. A damaged grinding wheel can
disintegrate without warning and cause serious
injury.
Wear suitable eye protection when using grinding,
chiseling or sand blasting equipment.
Wear a suitable breathing mask when using
abrasive blasting equipment, working with
asbestos-based materials or using spraying
equipment.
Make sure there is adequate ventilation to control
dusts, mists and fumes.
High Pressure Air, Lubrication and Oil
Test Equipment
See also Lubricants and Greases.
Always keep high-pressure equipment in good
condition, and regularly maintained, particularly at
joints and unions.
Never direct a high-pressure nozzle, for example
diesel injector, at the skin as the fluid may
, penetrate to the underlying tissue, and cause
serious injury.
Halon
See CFCs.
Legal Aspects
There are many laws and regulations relating to
health and safety in the use and disposal of
materials and equipment in a workshop.
For a safe working environment and to avoid
environmental pollution, workshops should be
familiar, in detail, with the many health and safety
laws and regulations within their country, published
by both national and local authorities.
Lubricants and Greases
Avoid all prolonged and repeated contact with
mineral oils. All lubricants and greases may be
irritating to the eyes and skin.
'
Transmission Fluids
Safety instructions
Certain Transmission and Power Steering fluids
supplied to Ford may contain additives which have
the potential to cause skin disease (dermatitis) to
exposed persons. The dermatitis may be irritant
or allergic in nature. Risks are higher where
prolonged or repeated skin contact with a fluid may
occur. These fluids are used for vehicle initial
fill
and service purposes. This sub-section is to:
Inform Service personnel who may come into
contact with these vehicle fluids (hazard
communication).
Summarise appropriate workplace control
measures and personal protective equipment
requirements.
Draw attention to the existence of Material
Safety Datasheets (MSDS's) for the fluids
(available from Ford Customer Service Division).
These MSDS's contain detailed information on
hazards and appropriate controls.
Control measures
Workplace risk assessments made under national
chemical control regulations should identify
operations involving the fluids as potentially
hazardous and specify workplace control and
worker awareness measures. In such
circumstances, the relevant Material Safety
Datasheet (see the details specified below) which
specifies hazards and control measures in detail
should be made available for guidance.
Avoid unprotected skin contact with the fluids, and
in particular, avoid prolonged or repeated skin
contact. Work practices should be organised so as
to minimise the potential for skin contact. This may
include the use of drip trays, absorbents, correct
fluid handling equipment (funnels etc), and
workplace housekeeping measures such as the
cleaning of contaminated surfaces.
Personnel engaged in operations where skin
contact could occur (such as fluid draining or filling)
should wear impervious gloves made from
nitrile
rubber, certified to a chemical protection standard,
e.g. Europe Standard EN374. This glove type is
widely available from reputable suppliers of gloves
for chemical protection [including the manufacturers
Ansell-Admont
(Solvex Range), North Safety
products (North
Nitrile Latex Gloves range), and

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.

100-04-6 Noise, Vibration and Harshness 100-04-6
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.
