General Fitting Instructions
Pressordrifttheseal in tothefull depthofthe housing ifthe housing is shouldered,orflush withthefaceofthe housing
where no shoulder is provided.
Note: Careless fitting of oil seals, which can result in damage to the seal and sealing surfaces, accounts for most
cases of failure of seals. Care in fitting is essential
if good results are to be obtained.
A3.2.7 joints And joint Faces
Remove all traces of old jointing materials prior to reassembly. Inspect joint faces for scratches or burrs and remove
with a fine file or oilstone; do not allow swarf or dirt to enter tapped holes or enclosed parts. Blow out any pipes, chan- nels or crevices with compressed air, refitting or renewing any 0-rings or seals which have been displaced by the com- pressed air.
Always use the specified gaskets. Use jointing compound only when recommended, otherwise fit joints dry. When
jointing compound is used, apply in
a thin film to metal surfaces; take great care to prevent it from entering oilways, pipes or blind tapped holes.
A3.2.8
Before removing a hose from the brake or power steering systems, thoroughly clean the end fittings and the area sur- rounding them. Obtain blanking caps beforedetaching hosefittings,sothat portscan becovered to excludedirt. Clean
the hose externally and blow through with compressed air. Examine the hose carefully for cracks, separation of plies,
security of end fittings and external damage. Reject any hose found to be faulty. When refitting the hose, ensure that
no unnecessary bends are introduced and that the hose is not twisted before or during tightening of union nuts.
Do not store hydraulic fluid in an unsealed container because it will absorb water. Fluid in this condition would be dan- gerous to use due to a lowering of its boiling point. Do not allow hydraulic fluid to be contaminated with mineral oil,
or use a container which has previously contained mineral oil.
Do not re-use fluid bled from the system. Always use clean brake fluid, or a recommended alternative, to clean the
hydraulic components. Fit a blanking cap to the hydraulic union and
a plug to its mating socket, after removal from
the vehicle, to prevent ingress of dirt. Absolute cleanliness must be observed with hydraulic components at all times.
After any work has been performed on hydraulicsystems, inspect carefully for leaks underneath the car while a second
operator applies maximum pressure to the brakes (with the engine running) and operates the steering.

A3.2.9 Metric
Bolt Identification
An IS0 metric bolt or screw, made of steel and larger than
6mm in diameter can be identified by the symbols ISOM or M embossed on top of the head (Fig. 1 ). In addition to marks
to identify the manufacturer, the head is also marked with
symbols to indicate the strength grade eg
8.8, 10.9, 12.9 or 14.9. The first figure gives the minimum strength of the bolt
material in tens of kgf / mm2. Zinc plated IS0 metric bolts
and nuts are chromate passivated and coloured greenish- khaki to gold-bronze.
A3.2.10 Metric Nut Identification
A nut with an IS0 metricthread is marked on one face (1 Fig. 2) or on one of the flats (2 Fig. 2) of the hexagon with the
strength grade symbol 8, 12 or 14. Some nuts with a
strength 4,5 or 6 are also marked and some have the metric
symbol M on the flat which is opposite to the strength grade
marking.
Aclockfacesystem is used as an alternative method of indi
- cating the strength grade (3 Fig. 2). The external chamfers
or a face of the nut is marked in a position relative to the ap-
propriate hour mark on a clock face to indicate the strength
grade. A dot is used to locate the 12 o’clock position and a dash to indicate the strength grade. If the grade is above 12,
two dots identify the 12 o’clock position. Fig.

- A3.2.19 Unified Thread Identification - Bolts
A circular recess is stamped in the upper surface of the bolt
head (1 Fig. 1).
A3.2.20 Unified Thread Identification - Nuts
A continuous line of circles is stamped on one of the flats of
the hexagon, parallel to the axis of the nut (2 Fig. 1).
A3.2.2 1 Unified Thread Identification - Studs, Brake
Rods, etc.
The component is reduced to the core diameter for a short
length at its extremity (3 Fig. 1).
A3.2.16 Nuts
When tightening a slotted or castellated nut, never slacken it in order to insert the split pin or locking wire, but tighten
it to align the next slot. The exception is in those recommended cases where slackening the nut forms part of an adjust- ment e.g. bearing endfloat or preload adjustment. If difficulty is experienced, alternative washers or nuts should be
selected, or a washer of a different thickness used. Where self-locking nuts have been removed, replace them with
new ones.
A3.2.17 Locking Wire
Fit new locking wire of the correct type to the assemblies incorporating it. Arrange the wire so that its tension tends
to tighten the bolt heads, or nuts, to which it is fitted.
A3.2.18 Screw Threads
Metricthreads to IS0 standards and UNF threads are used. See below forthread identification. Fixings with damaged
threads must always be discarded. Cleaning the threads with a die or tap impairs the strength and closeness of fit and
is not recommended. Always ensure that replacement bolts are of equal strength to those removed. Do not allow oil,
grease or jointing compound to enter blind threaded holes because the hydraulic action which would be generated
when screwing in the bolt or stud could split the housing. Oil the thread lightly before tightening to ensure
a free run- ning thread, except in the case of self locking nuts. Always tighten a nut or bolt to the recommended torque figure.
Damaged or corroded threads will affect the torque reading. To check or retighten a bolt or screw to a specified torque
figure, first slacken by a quarter of a turn, then retighten to the correct figure.

A4.1.3. POTENTIAL RISKS I
A4.1.3. Paint
Organic solvents, found in paints, may cause damage or severe irritation to liver, kidneys, digestive tracts and respira- tory system if inhaled over long periods of time.
Prolonged exposure to isocyanates may cause lung sensitization. Asthma
-like symptoms may develop with subse-
quent exposure to very low concentrations of isocyanates.
Solvent inhalation can cause dizziness or loss of consciousness.
Splashes of solvents, paint activators and additives can cause damage to the eyes and may cause dermatitis. Peroxide
and acid catalysts may cause burns.
Inhalation of
spray dust and sanding debris may cause lung damage.
I
A4.1.3.2 Applied Heat (Welding)
There is considerable risk of damage to eyes and skin when welding or flame cutting.
Fire is a serious danger and many materials or fluids within the vehicle are highly flammable.
Toxic and dangerous fumes may be liberated when any of the following are subjected to heat:
0 Expanded foam
0 Corrosion protection
0 Trim and seat materials
0 Paints which contain isocyanates
0 Adhesive and sealing compounds
When heated to a temperature of 3OO0C, polyurethane based compounds may liberate small quantities of isocyanate.
Many types of nitrogen containing chemicals may be liberated as breakdown products; these chemicals can contain
isocyanates, oxides of nitrogen and hydrogen cyanide.
Potentially toxic or asphyxiant fumes and gases are produced by welding, for example; zinc oxide with zinc coated
panels, and ozone gas from the MIG process.
A4.1.3.3 Metal Repair
There is considerable risk of damage to eyes, ears and skin when metal cutting, forming, or dressing is being carried
out.
Soldering may be hazardous because of heat generated fumes and skin contact with the materials.
A4.1.4. PRECAUTIONS
A4.1.4.1 Paint
The inhalation of sprays, fumes, or dust during paint application or sanding processes should always be avoided. En- sure that there is efficient ventilation / extraction at all times. Paint spraying should be confined as far as possible to
spray booths. Personnel with a history of asthma should not be engaged in any process which involves the use of
isocyanates. Any operator working inside
a spray booth where isocyanate material is present must use air-fed breath- ing equipment. Supplied air to the visor should be fed at the recommended pressure and filtered to remove oil, water,
and fumes. Operators involved in handling mixing or spraying should wear protective clothing - gloves and goggles,
to avoid skin and eye contact.
A particle mask or canister type respirator should be worn when sanding.
A4.1.4.2 Applied Heat
When welding, flame cutting, brazing etc, the operator should use as appropriate, goggles, mask/fume extractor and
flameproof protective clothing. It is especially important when working with polyurethane compounds to use air-fed
breathing equipment.
Ensure that
at all times the appropriate fire fighting equipment is available and that personnel are trained in its use.
A4.1.4.3 Metal Repair
Appropriate eye and hand protection should be worn when sanding, drilling, cutting, chiselling, flatting or welding.
Operators should wear
a face mask or air-fed visor when sanding or flatting either body solder or fillers.
When
a soldering operation has been completed, swarf must be removed from the work area and the operator must
wash his hands thoroughly.
