Highly flammable, flammable - observe No Smoking policy

Pressurized Equipment

See High Pressure Air, Lubrication and Oil Test Equipment.

Solder

Solders are a mixture 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 gas/air 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 etc. 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.
e.g. acetone, white spirit, toluene, xylene, trichloroethane.

Used in cleaning and de-waxing materials, paints, plastics, resins, thinners etc.
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 to 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 (e.g. 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.

Ensure 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, e.g. 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 manufacturer's instructions.

Sound Insulation

See Fibre Insulation, Foams.

Suspended Loads


CAUTION: Never improvise lifting tackle.

There is always a danger when loads are lifted or suspended. Never work under an unsupported, suspended or raised load e.g.
suspended engine, etc.

Always make sure that lifting equipment such as jacks, hoists, axle stands, slings, etc., are adequate and suitable for the job,
in good condition and regularly maintained.

General Information - Road/Roller Testing
Description and Operation Published: 11-May-2011

Road or roller testing may be carried out for various reasons and a procedure detailing pre-test checks, through engine starting
and stopping, pre-driving checks, on-test checks to final checks on completion of the test is given in this section.

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


WARNING: If 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/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.

Engine oil level
Engine coolant level
Tires, for correct pressure, compatible types and tread patterns, and wear within limits
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


CAUTION: On initial drive away from cold and within the first 1.5 km (1 mile), do not depress accelerator pedal beyond
half travel until the vehicle has attained a minimum speed of 25 km/h (15 miles/h). 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:
The parking brake is applied
The transmission selector lever is in Park
All instrument gauges (except fuel gauge) read zero

With the ignition switched on, check:

Ignition controlled warning lamps come on
Engine coolant temperature gauge registers a reading compatible with the engine coolant temperature
Fuel gauge registers a reading appropriate to the fuel level in the tank
The operation of the parking brake and brake fluid level warning lamps

On Road or Roller Test Check:


CAUTION: If road testing, check the brake operation while still travelling 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.
Initial gear engagement is smooth
Parking brake control operates smoothly and the parking brake releases quickly and completely
Transmission takes up the drive smoothly, without judder
The engine power output is satisfactory, full power is achieved, acceleration is smooth and pedal operation 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
Steering operation, including power steering, is smooth, accurate, not excessively heavy or with excessive free play or
vibration. Does not pull to one side and self centres smoothly after cornering
Speedometer, oil pressure warning lamp, coolant temperature gauge and tachometer register the correct readings or
operate correctly
Switches and controls operate smoothly and positively, warning lamps operate correctly and the direction indicator
control self cancels when the steering is returned to the straight ahead position
Heating and ventilation systems work correctly and effectively
Brake operation and efficiency

Brake Testing


WARNING: When brake testing, avoid breathing the smoke or fumes from hot brakes, this may contain asbestos dust
which is hazardous to health, see Health and Safety Precautions.

Avoid brake testing on busy roads where it can cause inconvenience or danger to other road users.


CAUTION: Brake testing which includes heavy brake applications should not be carried out with new brake pads/discs or
linings/drums until the components have bedded-in. New brake friction components will not reach full efficiency until the
bedding-in process is complete.

Test the brakes at several speeds within the normal operating range using both light and heavy pedal pressure. Note any
tendency to snatch, pull or drag, and any undue delay in application or release.
Allow the vehicle to coast and note any tendency to pull to one side, or evidence that the brakes are binding.

After stopping the vehicle (not immediately after a period of heavy braking), carefully check the brake temperature. A disc
which feels hot, or appreciably hotter than the others, indicates that the brake is binding.
After completion of the test, check for:
Oil, coolant, hydraulic, air and fuel leaks
Abnormal temperature of any moving components or assemblies, e.g. wheel hubs, transmission, axle etc., which might
indicate over tightness or lack of lubrication

60 Oil seal The multi-plate clutch is contained in a clutch basket attached to the differential carrier with the crown wheel securing bolts.
Alternate plates of the clutch pack are keyed to the clutch basket and the LH sun gear. A pressure disc is installed on the outer end of the clutch pack and keyed to the clutch basket. A thrust race on the end of the clutch basket incorporates lugs which
extend through the clutch basket onto the pressure disc.

The actuator assembly is mounted on bearings on the outboard end of the clutch basket, against the thrust race. The actuator
assembly consists of input and output actuators separated by five ball bearings. A locking pin in the cover engages with a slot
in the output actuator to prevent it turning, but allow it to move axially. The input actuator engages with the reduction gearbox
and is free to rotate relative to the cover. Ball bearings locate in curved grooves in the mating faces of the input and
output actuators. The bottom surface of each groove incorporates a ramp. Rotation of the input actuator forces the ball
bearings up the ramps in the grooves and induces an axial movement in the output actuator. The thrust race and pressure disc
transfer the axial movement from the output actuator to the clutch pack.



Item Description 1 Actuator 2 Multi-plate clutch 3 Differential The motor is a 12 V dc motor that adjusts the frictional loading of the multi-plate clutch, via the reduction gearbox and the
actuator assembly, under the control of the DLM. Adjusting the frictional loading of the multi-plate clutch adjusts the locking
torque between the crown wheel drive gear and the sun wheel.

Four bolts attach the motor to the reduction gearbox, which is located in position on the cover with two dowels, and secured
with four bolts. An O-ring seals the joint between the motor and the reduction gearbox.

The motor is driven by a 12 V dc feed direct from the DLM. The motor also incorporates the following connections with the
DLM:

A motor temperature sensor, to prevent excessive use from damaging the motor.
Two Hall effect motor position sensors, to enable closed loop control of the motor.

The temperature sensor provides a differential oil temperature signal to the DLM, to prevent excessive use from damaging the
multi-plate clutch.

Differential Locking Module (DLM)

The DLM controls operation of the electronic differential. The DLM is attached to a bracket located on the LH side of the luggage compartment, immediately forward of the fender tail lamp, behind the trim.

NOTES:


If an engine is suspect, and the vehicle remains under the Manufacturers warranty refer to the Warranty Policy and
Procedure manual (section B1.2), or determine if any prior approval programme is in operation, prior to the installation of a
new engine.


Due to the possibility of loose carbon, that has become trapped between the valve face and seat, effecting the pressure
readings, when carrying out a compression test and some cylinders are found to have low pressures, install the spark plugs,
road test the vehicle and re-test the suspect cylinders. If the correct pressures are restored, no further action is required. www.JagDocs.com
