GLOSSARY OF TERMS
Introduction
This glossary of terms is intended to cover both general and emissions-related (to SAE J 1930) terminology. It is in- tended to enable the user to ascertain the meaning of standardized terms and acronyms used throughout the Manual.
The required term may be looked-up in the left-hand column, and subsequent columns give the standard abbreviation
or acronym, definitions and previously used terms, as applicable.
As this Manual is a world
-wide publication, and must comply with certain Society of Automotive Engineers Standards, it has been necessary to adopt the terminology etc. demanded by that Standard.

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.

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.
