Climate Control Systems
0 Because HFC 134A is fully recycleable it may be 'cleaned' by the recovery equipment and re-used following
removal from a system.
0 Leak tests should only be carried out with an electronic analyzer which is dedicated to HFC 134A. Never use a CFC 12 analyzer or naked flame type.
0 Do not attempt to 'guess' the amount of refrigerant in a system, always recover and recharge with the correct
charge weight. In this context do not depress the charge or discharge port valves to check for the presence of
refrigerant.
14.1.3 Handling Lubricating Oil
0 Avoid breathing lubricant mist, it may cause irritation to your respiratory system.
0 Always decant fresh oil from a sealed container and do not leave oil exposed to the atmosphere for any reason
other than to fill or empty a system. PAG oil is very hygroscopic (absorbs water) and will rapidly become con-
taminated by atmospheric moisture.
PAG oil is
NOTcompatible with previously used mineral based oils and must NEVER be mixed (Fig. 1). Do not
re
-use oil when it has been separated from refrigerant, following a recovery cycle. Dispose of used oil safely.
14.1.4 System Maintenance
0 When depressurizing a system do not vent
refrigerant directlyto atmosphere, always use Jaguar
approved recovery equipment.
0 Always decant compressor oil from a sealed con- tainer and do not leave oil exposed to the atmosphere
for any reason other than to fill or empty
a system.
PAG oil is very hygroscopic and will rapidly become
contaminated by atmospheric moisture.
0 Plug pipes and units immediately after disconnection
and only unplug immediately priorto connection. Do
not leave the system open to atmosphere.
0 It is not necessary to renew the receiver drier when- ever the system has been 'opened' as previously ad-
vised - see note this page. However,if a unit or part
of the system is left open for more than five minutes,
it may be advisable to renew the receiver drier. This
guidance is based on
U.K average humidity levels;
therefore, locations with lower humidity will be less
critical to moisturecontamination of the unit.
It must
be stressed that there is not
a 'safe' period for workto
be carried out in: ALWAYS plug pipes and units im-
mediately after disconnection and only remove plugs
immediately prior to connection.
J82-387
Fin. 1
U: The receiver / drier MUST be renewed if the compressor has failed or if it is suspected that debris may be in
the system.
0 If replacement parts are supplied without transit plugs and seals DO NOT use the parts. Return them to your
supplier.
0 Diagnostic equipment for pressure, mass and volume should be calibrated regularly and certified by a third
party organization.
0 Use extreme care when handling and securing aluminium fittings, always use a backing spanner and take
special care when handling the evaporator.
0 Use only the correct or recommended tools for the job and apply the manufacturer's torque specifications.

0 14.9 GENERAL SYSTEM PROCEDURES
14.9.1 Leak Test
Faults associated with low refrigerant charge weight and low pressure may be caused by leakage. Leaks traced to
mechanical connections may be caused by torque relaxation or joint face contamination. Evidence of oil around such
areas is an indicator of leakage. When checking for non visible leaks use only
a dedicated HFC 134A electronic analyzer
and apply the probe all round the joint / connection.
Should a leak betraced to a joint,checkthatthefixing issecuredtothecorrecttightening torque before any other action
is taken.
Do not forget to check the compressor shaft seal and evaporator.
CAUTION : Never use a dedicated CFC 12 or naked flame type analyzer.
14.9.2 Charge Recovery (System depressurization)
The process of HFC 134A recovery will depend on the basic characteristics of your chosen recovery/ recycle I recharge
equipment, therefore, follow the manufacturer's instructions carefully.
Remember that compressor oil may be drawn
out of the system by this process, take note of the quantity recovered
so that it may be replaced.
CAUTION: Observe all relevant safety requirements.
Wear suitable eye and skin protection
Do not mix HFC 134A with CFC 12. Do not vent refrigerant directly to atmosphere and always use Jaguar approved recovery I recycle I re- charge equipment.
Take note of the amount of recovered refrigerant, it will indicate the state of the system. 0
14.9.3 Evacuating the System
This process, the removal of unwanted air and moisture, is critical to the correct operation of the air conditioning sys-
tem. The specific procedures will vary depending on the individual characteristics of your chosen recovery I recycle / recharge equipment and must be carried out exactly in accordance with the manufacturers instructions. However,
it is recommended that the initially only the HIGH side valve be opened at the start of the procedure. After a short time a small depression should be seen on the LOW side, at which point the LOW side valve may be opened and the evacu- ation process completed. If a vacuum is not registered on the LOW side it may indicate that the expansion valve is
jammed closed or that the system is blocked. This simple check may save time and effort when the system is re- charged.
Moisture can be highly destructive and may cause internal blockages due to freezing, but more importantly, water sus- pended in the PAG oil will damage the compressor. Once the system has been opened for repairs, or the refrigerant
charge recovered, all traces of moisture MUST be removed before recharging.
14.9.4
The amount of oil drawn out during a recovery procedure will be dependent on the state of the system and the rate
of recovery. The quantity will be approximately 30 to 40 ml; this may vary, and the figure is given only for guidance.
The oil separator vessel in the recovery equipment must be clean and empty
at the start of the process so that the quan- tity of oil which is drawn out may be accurately measured.
Oil may be added by three methods,
1 and 2 being direct into the system and 3 with the compressor off the vehicle;
1. Via the recovery I recycle 1 recharge station.
2. Proprietary oil injector.
Adding Lubricating Oil - Compressor Related
1ynfa: Equipment manufacturer's instructions must be adhered to when using direct oil introduction.
3. Directly into the original, or new unit, because of rectification work to the existing compressor, or the need to fit a new compressor.
Original
From an existing compressor, drain the oil into a measuring cylinder and record the amount. Flush the unit out
with fresh PAG oil and drain thoroughly, Replenish the compressor with the same amount of PAG oil that was
originally drained out and immediately plug all orifices ready for refitting to the vehicle.

14.13 SYSTEM CHECKING WITH MANIFOLD GAUGE Sm
14.13.1 Evacuating the Manifold Gauge Set
Attach the centre (service) hose to a vacuum pump and start the pump. Open fully both high anddow valves and allow
the vacuum to remove air and moisture from the manifold set for at least five minutes.
Turn the vacuum pump off and isolate it from the centre service hose but do not open the hose to atmosphere.
CAUTION: It is imperative that the vacuum pump is not subjected to a positive pressure of any degree. Therefore
the pump must be frtted with an isolation valve at the centre (service hose) connection and this valve
must be closed before the pump is switched off. This operation replaces the 'purge' procedure used on
previous systems. Observe the manufacturefs recommendation with regard to vacuum pump oil
changes.
14.13.2 Connecting the Manifold Gauge Set
CAUTION: Only use hoses with connectors which are dedicated to HFC 134A charge ports.
Attachment of the hose quick release connectors to the high and low side system ports is straightfotward, provided
that the high and low valves are closed and the system is NOT operational.
Assessment of system operating efficiency and fault classification may be achieved by using the facilities on your
Re- covery / Recharging / Recycling station, follow the manufacturers instructions implicitly and observe all safety con- siderations.
WARNING: UNDER NO CIRCUMSTANCES SHOULD THE CONNECTIONS BE MADE WITH THE SYSTEM IN
OPERATION OR THE VALVES OPEN. SHOULD THE VALVES BE OPEN AND A VACUUM PUMP OR
REFRIGERANT CONTAINER ATTACHED, AN EXPLOSION COULD OCCUR AS A RESULT OF HIGH
PRESSURE REFRIGERANT BEING FORCED BACK INTO THE VACUUM PUMP
OR CONTAINER.
14.13.3 Stabilizing the System
Accurate test gauge data will only be attained if the system temperatures and pressures are stabilized.
Ensure that equipment and hoses cannot come into contact with engine moving parts or sources of heat.
It is recommended that a free standing air mover is placed in front of the vehicle to provide air flow through the con- denser / cooling system, see illustration below.
Start the engine, allow
it to attain normal working temperature and set at fast idle (typically 1200 to 1500 rpm). Select full air conditioning performance.
With all temperatures and pressures stable, or displaying symptoms of faults; begin relevant test procedures.

used.
WARNING: FUME EXTRACTION EQUIPMENT MUST BE IN OPERATION WHEN SOLVENTS ARE USED E.G.
TRICHLOROETHANE, WHITE SPIRIT, SBPB, METHYLENE CHLORIDE, PERCHLORETHYLENE.
DO NOT SMOKE IN THE VICINITY OF VOLATILE DEGREASING AGENTS.
Adhere strictly to handling and safety instructions given on containers and labels. Keep oils and solvents away from
naked flames and other sources of ignition. Do not apply heat in an attempt to free seized nuts or fittings; as well as
causing damage to protective coatings, there is
a risk of damage from stray heat to electronic equipment and brake
lines. Do not leave tools, equipment, spilt oil etc. around or on work
area. Wear protective overalls and use barrier
cream when necessary.
0 A3.1.1 Used Engine Oils
Prolonged and repeated contact with mineral oil will result in the removal of natural oils from the skin, leading to dry- ness, irritation 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.
A3.1.2 Health Protection Precautions
0 Avoid prolonged and repeated contact with oil; particularly used engine oils.
o Wear protective clothing, including impervious gloves where practicable
0 Do not put oily rags in pockets.
0 Avoid contaminating clothes, particularly underwear, with oil.
0 Overalls must be cleaned regularly. Discard unwashable clothing and footwear which is oil impregnated.
o First Aid treatment should be obtained immediately for open cuts or wounds.
0 Use barrier creams, applying before each work period, to enable easier removal of dirty oil / grease from the
skin.
0 Wash with soap and water to ensure that 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.
o Do not use petrol, kerosene, gas oil, thinners or solvents for washing skin.
0 If skin disorders develop, obtain medical advice immediately.
0 Where practicable, degrease components prior to handling.
0 Where there is a risk of fluids coming into contact with the eyes, eye protection should be worn, for example,
goggles or a face shield. An eye wash facility should be provided.
A3.1.3 Environmental Protection Precautions
A3.1 SAFETY PRECAUTIONS
Whenever possible, use a ramp or pit whilst working beneath a car, in preference to jacking. Position chocks at the
wheels as well as applying the handbrake. Never rely on a jack alone to support a car. Use axle stands, or blocks care- fully placed at the jacking points, to provide a rigid location. Checkthat any lifting equipment used has adequate capac- ity and is fully serviceable. Ensure that a suitable form of fire extinguisher is conveniently located.
When using
electrical tools and equipment, inspect the power lead for damage and check that it is properly earthed. Disconnect
the earth (grounded) terminal of the car battery. Do not disconnect any pipes of the air conditioning refrigeration sys-
tem 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. Ensure that adequate ventilation is provided when volatile degreasing agents are being
It is illegal to pour used oil on to the ground, down sewers or drains, or into water courses. The burning of used engine
oil in small space heaters or boilers is not recommended 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.

General Fitting Instructions
A3.2 GENERAL FITTING INSTRUCTIONS
A3.2.1
Always fit covers to protect the wings before commencing work in the engine compartment. Cover the seats and
carpets, wear clean overalls and wash hands or wear gloves before working inside the car. Avoid spilling hydraulic
fluid, anti
-freeze or battery acid on the paintwork. In the event of spillage, wash off with water immediately. Use poly- thene sheets in the boot to protect carpets. Always use the recommended service tool, or a satisfactory equivalent,
where specified. Protect temporarily exposed screw threads by replacing nuts or fitting caps.
Precautions Against Damage To The Vehicle
A3.2.2 Preparation
Before disassembly, clean the surrounding area as thoroughly as possible. When components have been removed,
blank off any exposed openings using greaseproof 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 hardwood plugs or readily visible plastic plugs. Immediately
a component is removed, place
it in a suitable container; use a separate container for each component and its asso- ciated parts. 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 marking materials, la-
bels, containers and locking wire before dismantling a component.
A3.2.3 Dismantling
Observe scrupulous cleanliness when dismantling components, particularly when parts of the brake, fuel or hydraulic
system are being worked on. A particle of dirt or a fragment of cloth could cause a dangerous malfunction if trapped in these systems. Clean all tapped holes, crevices, oilways and fluid passages with compressed air.
WRNIFLG: DO NOT PERMIT COMPRESSED AIR TO ENTER AN OPEN WOUND. ALWAYS USE EVE 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 marking materials which avoid the possibilities of caus- ing distortion or the initiation of cracks, which could occur if a center punch 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 for reassembly.
Place labelled parts and other parts for rebuild
in separate containers.
Do not discard a part which is due for renewal until it has been compared with the new part, to ensure that the correct
part has been obtained.
A3.2.4 Inspection
Before inspecting a component for wear or performing 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 dimensions are outside the limits quoted,
or if damage is apparent. A part may be refitted if its critical dimension 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
journal. 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.

in these areas indicates the onset of wear.
Hold the inner race between the fingers and thumb of one hand, spin the outer race and checkthat
it revolves absolutely
smoothly. Rotate the outer ring with a reciprocating motion, while holding the inner ring; feel for any obstruction to
rotation and reject the bearing if the action is not perfectly smooth. Lubricate the bearing generously with lubricant
appropriate to the installation. Inspect the shaft and bearing housing for discolouration or other marking which may
suggest that movement has taken place between the bearing and bearing seat.
If markings are found, use Loctite when
installing the replacement bearing.
Ensure that the shaft and housing
are clean and free from
burrs before fitting the bearing. If one bearing of a pair
shows an imperfection, it is generally advisable to renew
both bearings: an exception could be made only if the bear- ings had covered a low mileage and it could be established
that damage was confined to the one bearing.
- In the case of bearings which are lubricated with grease (e.g.
hub bearings) the space between the bearings should be
smeared with a recommended grade of grease, and the
bearings and seal should be re
-packed. When fitting the
bearing to the shaft, apply force only to the inner ring of
bearing (Fig.
1A). When fitting the bearing to the housing,
apply force only to outer ring (Fig. 1B).
Always mark components of separable bearings (e.g taper
roller bearings) when dismantling, to ensure correct
reassembly. Never
fit a new inner roller assembly to a used
outer track.
A3.2.6 Oil Seals
Always fit new oil seals when rebuilding an assembly.
Examine the seal before fitting to ensure that it is clean and
undamaged. Smear sealing lips with clean grease, pack
dust excluder seals with grease and pack grease into the
cavity between the sealing lips of duplex seals. Ensure that
the seal spring,
if provided, is correctly fitted.
Place the lip
of the seal towards the fluid to be sealed and
slide it into position on the shaft, using a fitting sleeve (Fig. 2) when possible to protect the sealing lip from damage by
threads, splines or sharp edges on the end of the shaft. If a fitting sleeve is not available, use plastic tube or adhesive
tape to prevent damage to the sealing lip.
Grease the outside diameter of the seal, place it square to the
housing recess and press it into position, using great care
and, where available, a seal installer (Fig. 3) to ensure that
the seal does not tilt. In some cases it may be preferable to
fit the seal to the housing before fitting it to the shaft. Never
let the weight of an unsupported shaft rest in a seal. If the
correct service tool is not available, use a piece of tube which
is approximately 0,4 mm (0.015 in) smaller than the outside
diameter of the seal. Use a press to install the seal or use a
hammer VERY GENTLY on the tubular drift if a press is un-
suitable or not available.

A3.2.5 Ball And Roller Bearings
CAUTION: Never replace a ball or roller bearing without first ensuring that it is in as-new condition.
Remove
all traces of lubricant from the bearing by washing it in petrol or a suitable degreaser. Maintain absolute
cleanliness throughout the operations. Inspect visually for markings of any form on rolling elements, bearing tracks,
outer surface of outer rings or inner surface of inner rings. Reject any bearings found to be marked, since any markings
