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.
Hydraulic Flexible Pipes And Hoses
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.

A4.6.6.2 Body-side Moulding - Fitfed Condition
A4.6.6 BODY-SIDE MOULDINGS
A4.6.6.1 Introduction
There are two types of moulding fitted to the standard wheelbase sedan.
The lower moulding is ‘self
-locating‘ on the body / door lower feature line and therefore provides a fixed datum for
the location of the upper moulding (wherefitted). Replacement lower mouldings will be supplied in a primed condition
and therefore must be finished in accordance with A4.6.3, this section.

. ‘Spirit wipe’ appropriate body panel and where appropriate protect against damage.
. Gently warm body panel and moulding using infa-red lamp or similar.
. Lower moulding - align to body feature and other mouldings if appropriate, and secure into position.
. Upper moulding - align to lower moulding for distance (Fig. 1) and parallelism and other mouldings if appropriate,
and secure into position.
. Apply an even pressure along the moulding to fully secure to the panel.

e A4.7.2 DOORS
A4.7.2.1 Features
The doors feature:
Lubricated for
life 'lift-off' hinges.
Welded drop glass frames.
Integral primary and secondary seal channels.
A4.7.2.2 Removal
Apply tape as Fig. 1 to avoid paint damage during the re- moval process.
rn Disconnect door harness at connector.
rn Remove locking screws Fig. 2.
rn Disconnect check-arm fixings at the body Fig. 2.
rn Open the door fully, carefully lift and disengage from the
hinge pins,
a A4.7.2.3 Fitting
Before refitting the door assembly, all traces of thread
locking compound must be removed from the hinge pins;
careful use of
a suitable thread tap is recommended.
rn Refit the door assembly and secure to specification using
new locking screws.
w: There is no need to lubricate the hinge when refit- ting the door.
Apply grease to the check-arm 3 Fig. 2
rn Ensure correct alignment and remove the protective tape.
A4.7.2.4 Alignment
Hinges are set during the body manufacturing process and
should not require adjustment during the life of the vehicle.
However, where damage has been sustained at the body or
door hinge location points, please refer to 'Body fits and
clearanc&' section A4.7.1.5 for setting criteria.
