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
P
rolonged and repeated contact with mineral oil will result in the removal of natural oils from the skin, leading to dryness,
In
spection
irri
tation and dermatitis. In addition, used engine oil contains potentially harmful contaminants which may cause skin
cancer. Washing facilities and adequate means of skin protection should be provided.
Observe these recommendations:
Wear pro t
ective clothing and impe
rvious gloves when necessary.
Do not put oily
rags in pockets. Avoid contaminat
ing clothes, particularly underwear, with oil.
Overal
ls must be cleaned re
gularly; discard oil impregna ted clothing and footwear wh ich cannot be washed or
cleaned.
Fi rst
Aid treatment should be obtained
immediately for open cuts or wounds.
Use barrier
creams, applying before each work period, to en
able easier removal of dirty oil and grease from the skin.
Wa
sh with soap and water to ensure th
at all oil is removed (skin cleaner and a nail brush will help). The use of
preparations containing lanolin will help to replace the natural skin oils which have been removed.
Do
not use petrol, kerosene, gas oil, th
inners or solvents for washing skin.
If
skin disorders develop, obtain medical advice immediately.
Wh
ere prac
ticable, degrease components prior to handling.
W
h
ere there is a risk of fluids coming into contact with th
e eyes, suitable eye protection should be worn - goggles or
face shield. An eye wash facility should be provided.
Ensure that a
dequate ventilation is provided when volatile degreasing agents are being used.
E
n
vironmental Protection
In so
m
e countries it is illegal to pour used oil onto the ground
, down sewers or drains, or into water courses. The burning of
used engine oil in small space heaters or boilers is not reco mmended unless emission control equipment is fitted. Dispose of
used oil through authorized waste disposal contractors, to licensed waste disposal sites or to the waste oil reclamation
trade. If in doubt, contact the Local Authority for advice on disposal facilities.
On-Board Diagnostics (OBD)
Ve
hicles use programmed electronic control systems to prov
ide engine management and emission regulation, automatic
transmission operation and anti -lock braking control. These control systems ha ve an integral On-Board Diagnostics (OBD)
facility for use in conjunction with either Jaguar diagnostic equipment or a scan t ool which is capable of retrieving DTCs,
PIDs and performing active commands.
The OBD information in this manual provid es diagnostic and rectification procedures for emission related electrical and
mechanical systems. The informat ion is intended to facilitate fault diagnosis and the subsequent rectification of vehicles
without recourse to the portab le diagnostic unit (PDU).
OBD related information can be fo und in the following sections:

Jacking and Lifting - Vehicle Recovery
Description an
d Operation
• NOTE: Prior to recovery, ensure that the vehicle keys are available and the security system disarmed.
Vehicle recovery methods are:
By fl
at-bed transporter.
By rear suspended tow.
By emergency to
wing for
very short distances.
Gears
hift Interlock
The
gear selector lever can only be moved
from the Park position by turning the igni tion key to position II and depressing
the brake pedal.
To remove the key from the ignition switch, the gear select or lever must be moved to the Park position. With the key
removed, the gear selector is locked in the Park position.
The selector lever can be manually unlocked from the Park position in the event of electrical failure or when moving the
vehicle without power. Refer to the general procedure in this section.
Transporter or Trailer Recovery
When the vehicle is being recove red by transporter or trailer:
The parking brake must be
be applied and the wheels chocked.
The
gear selector lever must be in Ne
utral. Do not select Park as the park ing lock mechanism may be damaged by
the forward and backward rocking motion of the vehicle.
The ve
hicle must be securely tied down to the transporter or
trailer. There are four tie-down brackets on the vehicle
underbody. Do not use the vehicle towing points or crossbeam tie bar.
