Torque Specifications
Torque sp
ecifications are shown in maintenance procedure illustra
tions and also in the torque specifications chart located at
the front of the relevant section.
Disconnecting/Connecting the Battery
Ow ing t
o the electronic components used on the vehicle, it is important that the battery is disconnected when specified in a
maintenance procedure.
When the battery is connected, the specified procedure must be followed, to ensure the correct operation of all vehicle
systems; refer to Section 414-01.
Use of Control Modules
Control modu les may
only be used on the ve
hicle to which they were originally fitted. Do not attempt to use or test a control
module on any other vehicle.
Function
al Test
On
completion of a maintenance procedure, a thorough test should be carried out, to ensu
re that the relevant vehicle
systems are working correctly.
Protecting the Vehicle
Al ways
fit covers to protect
the fenders before commencing work in the engi ne compartment. Cover the seats and carpets,
wear clean overalls and wash hands or wear gloves before working inside the vehicle. Avoid spilling hydraulic fluid,
antifreeze or battery acid on the paintwork. In the event of spillage, wash off with water imme diately. Use polythene sheets
in the trunk to protect carpets. Always use the recommended service tool, or a satisfactory equivalent, where specified.
Protect temporarily exposed screw thread s by replacing nuts or fitting caps.
Preparation
Before disassembly, clean the surrounding ar ea
as thoroughly as possible. When co
mponents have been removed, blank off
any exposed openings using grease-proof paper and masking tape. Immediately seal fuel, oil and hydraulic lines when
separated, using plastic caps or plugs, to prevent loss of fluid and the entry of dirt. Close the open ends of oilways, exposed
by component removal, with tapered hardw ood plugs or readily visible plastic plugs. Immediately a component is removed,
place it in a suitable container; use a se parate container for each component and its associated pa rts. Before dismantling a
component, clean it thoroughly with a recommended cleaning agent; check that the agent will not damage any of the
materials within the component. Clean the bench and obtain ma rking materials, labels, containers and locking wire before
dismantling a component.
Dismantling
O b
serve scrupulous cleanliness when dismantling components,
particularly when parts of the brake, fuel or hydraulic
systems are being worked on. A particle of dirt or a fragment of cloth could caus e a dangerous malfunction if trapped in
these systems. Clean all tapped holes, crev ices, oilways and fluid passages with compressed air. Do not permit compressed
air to enter an open wound. Always use ey e protection when using compressed air.
Ensure that any O-rings used for sealing are correctly refitted or renewed if disturbed. Mark mating parts to ensure that
they are replaced as dismantled. Whenever possible use markin g materials which avoid the possibilities of causing distortion
or the initiation of cracks, which could occur if a center pu nch or scriber were used. Wire together mating parts where
necessary to prevent accidental interchange (e.g roller bearing components). Tie labels on to all parts to be renewed and to
parts requiring further inspection before being passed fo r reassembly. Place labelled parts and other parts for rebuild in
separate containers. Do not disc ard a part which is due for renewal until it ha s been compared with the new part, to ensure
that the correct part has been obtained.
Page 39 of 2490
Before inspecting a component for wear or per
forming a dimensional check,
ensure that it is absolutely clean; a slight smear
of grease can conceal an incipient failure. When a component is to be checked dimensionally against figures quoted for it,
use the correct equipment (surface plates, micrometers, dial gauges etc.) in serviceable condition. The use of makeshift
equipment can be dangerous. Reject a component if its dimensio ns are outside the limits quoted, or if damage is apparent.
A part may be refitted if its critical di mension is exactly to the limit size and it is otherwise satisfactory. Use Plastigauge 12
Type PG-1 for checking bearing surface clearance, e.g. big end bearing shell to crank jour nal. Instructions for the use of
Plastigauge and a scale giving bearing clearances in steps of 0.0025 mm (0.0001 in) are supplied with the package.
Safety
Precautions
• WAR
NINGS:
WORKING ON THE FUEL SYSTEM RESULTS IN FUEL AND FUEL VAPOUR BEING PRESENT IN THE ATMOSPHERE. FUEL
VAPOUR IS EXTREMELY FLAMMABLE, HENCE GREAT CARE MUST BE TAKEN WHILST WORKING ON THE FUEL SYSTEM.
ADHERE STRICTLY TO THE FOLLOWING PRECAUTIONS:
DO
NOT SMOKE IN THE WORK AREA.
DISP
LAY 'NO SMOKING' SIGNS AROUND THE AREA.
DISCONNECT TH
E BATTERY BEFORE WORKING ON THE FUEL SYSTEM.
DO NOT CONNEC
T/DISCONNECT ELECTRICAL CIRCUITS
, USE ELECTRICAL EQUIPMENT OR OTHER TOOLS OR
ENGAGE IN WORKING PRACTICES WHICH IN ANY WAY MAY RESULT IN THE PRODUCTION OF SPARKS.
ENS
URE THAT A CO2 FIRE EXTINGUISHER IS CLOSE AT HAND.
ENS
URE THAT DRY SAND IS AVAILABLE TO SOAK UP ANY FUEL SPILLAGE.
EMP
TY FUEL USING SUITABLE FIRE PROOF EQUIPMENT IN
TO AN AUTHORIZED EXPLOSION PROOF CONTAINER.
DO NOT EMP
TY FUEL WHILE WORKING IN A WORKSHOP OR A PIT.
ENS
URE THAT WORKING AREA IS WELL VENTILATED.
ENS
URE THAT ANY WORK ON THE FUEL SYSTEM IS ON
LY CARRIED OUT BY EXPERIENCED AND WELL QUALIFIED
MAINTENANCE PERSONNEL.
ENS
URE THAT FUME EXTRACTION EQUIPMENT IS USED WHERE APPROPRIATE.
FUME EXTRACTION EQUIPMENT MUST BE IN OPERATION WHEN SOLVENTS ARE USED E.G. TRICHLOROETHANE,
WHITE SPIRIT, SBP3, METHYLENE CHLORIDE, PERCHLORETHY LENE. DO NOT SMOKE IN THE VICINITY OF VOLATILE
DEGREASING AGENTS.
General workshop practices:
Disc
onnect the grounded termin
al of the vehicle battery.
D
o not apply heat in an attempt to free seized nuts or fitt
ings; as well as causing damage to protective coatings,
there is a risk of damage from stray heat to electronic equipment and brake lines.
Keep oils and solven
ts away from naked flames and other sour
ces of ignition.
Adhere str
ictly to handling and safety inst
ructions given on containers and labels.
E
nsure that a suitab
le form of fire extinguisher is conveniently located.
Wh
en using electrical tools and equipment, inspect the power
lead for damage and check that it is properly earthed.
D
o not leave tools, equipment, spilt oil etc. around the work area.
Working beneath a vehicle:
Wh
enever possible, use a ramp or
pit in preference to jacking.
Posit
ion chocks at the wheels as we
ll as applying the parking brake.
N
ever rely on a jack alone to support a
vehicle; use axle stands, or blocks care fully placed at the jacking points, to
provide a rigid location.
Ch
eck that any lifting equipment used has adeq
uate capacity and is fully serviceable.
Working on air conditioning systems:
D
o not disconnect any pipes of the refrigeration system
unless you are trained and instructed to do so; a refrigerant
is used which can cause blindness if allowed to come into contact with the eyes.
Health Protection

rolonged and repeated contact with mineral oil will result in the removal of natural oils from the skin, leading to dryness,
