WHEELS AND TYRES

REPAIR Off vehicle balancing
Balance wheel assembly referring to equipment
manufacturer's instructions.
It is essential that the wheel is located by the centre
holeNOTthe stud holes. To ensure positive wheel
location the diameter of the locating collar on the
machine shaft must be 112.80 to 112.85 mm (4.441 to
4.443 in). This diameter will ensure that the collar fits
correctly within the centre hole of the wheel.
Where possible always use the vehicle wheel
retaining nuts to locate the wheel on the balancer, to
avoid damaging the wheel. If this is not possible, the
locating nuts must be of a similar pattern to the
original wheel nuts. The use of conical type wheel
nuts for this purpose may damage the aluminium
alloy.
Cleaning
Wash the aluminium wheels using a suitable wash
and wax concentrate correctly diluted and rinse with
cold clear water.DO NOTuse abrasives or aluminium
wheel cleaners containing acid, as they will destroy
the lacquer finish.
Tyre changing
Use only tyre changing equipment to mount or
demount tyres, following the equipment
manufacturer's instructions.DO NOTuse hand tools
or tyre levers, as they may damage tyre beads or the
aluminium wheel rim.
Puncture repair
Remove punctured tyre from wheel and repair using a
combination service plug and vulcanising patch.
Always follow manufacturer's instructions when using
a puncture repair kit.
Only punctures in tread area are repairable,DO NOT
attempt to repair punctures in tyre shoulders or
sidewalls.
Do not attempt to repair a tyre that has sustained the
following: bulges or blisters, ply separation, broken or
cracked beads, wear indicators visible and punctures
larger than 6 mm diameter.
CAUTION: Do not use tyre sealants that
are injected through valve stem to repair
punctured tyres, they may produce wheel
corrosion and tyre imbalance.
Aluminium wheel rim bead seats should be cleaned
using a non-abrasive cleaner to remove the mounting
lubricants and old rubber. Before mounting or
demounting a tyre, bead area should be well
lubricated with a suitable tyre lubricant.
TYRE FITTING
Alloy wheels
1.Install a new valve assembly.
2.Ensure wheel and tyre is adequately lubricated.
3.Mount tyre in normal manner. Inflate tyre and at
same time apply hand pressure to area around
valve to aid seating over valve first.
NOTE: Stop inflation immediately if tyre
seats opposite valve, as this will result in
valve being blocked by tyre beading,
making further inflation impossible, and carry out
following procedure.
4.Deflate tyre, unseat and rotate it around the rim
until valve is in line with that part of tyre which
seated initially. This part of beading having
seated over hump previously will automatically
seat first when tyre is re-inflated.
5.Inflate tyre to seat beads correctly, finally inflate
to correct pressure.

REPAIR ROTARY COUPLER CENTRALISE
Fitting a rotary coupler which has not been centralised
could result in tape breakage. If the tape is broken, a
new rotary coupler must be fitted.
Providing the removal procedure has been correctly
followed this operation should not be necessary. If
however there is evidence of tampering, it is
imperative that the coupler is centralised.
CAUTION: Ensure wheels are positioned
straight ahead before fitting the rotary
coupler.
1.Correctly fit rotary coupler to column switch
assembly but do not fit steering wheel or make
any electrical connections.
See rotary coupler.
2.Depress rotary coupler locking peg and without
using undue force, rotate coupler anti-clockwise
as far as inner tape will allow. Releasing peg will
lock coupler in its current position.
NOTE: Do not apply excessive force when
limit is reached as this may result in tape
breakage. If no limit can be found, tape
has already broken and rotary coupler must be
replaced.
3.Having turned rotary coupler fully anti-clockwise
to limit position, proceed to turn coupler 2.5 turns
clockwise to obtain central position. (Coupler will
normally rotate a full five turns from
anti-clockwise limit to clockwise limit).
4.Make necessary electrical connections and refit
steering wheel.
See steering wheel.
5.Refit driver's airbag module.See driver's
airbag module.

wing [fender] sufficiently to allow removal of the
aerial before completing the removal.Cleaning/painting
10.Thoroughly clean all traces of existing sealant
from the sealing faces of the valance and 'A'
post.
11.Paint the cleaned surfaces with etch primer.
12.If the existing wing [fender] is to be refitted
repeat the cleaning and painting procedure on
the wing [fender] sealing surfaces.

DESCRIPTION AND OPERATION ELECTRICAL EQUIPMENT
DESCRIPTION
The electrical system is Negative ground, and it is
most important to ensure correct polarity of the
electrical connections at all times. Any incorrect
connections made when reconnecting cables may
cause irreparable damage to the semi-conductor
devices used in the generator and regulator. Incorrect
polarity would also seriously damage any
transistorized equipment such as radio and
tachometer etc.
WARNING: During battery removal or
before carrying out any repairs or
maintenance to electrical components
always disconnect the battery negative lead first.
If the positive lead is disconnected with the
negative lead in place, accidental contact of the
wrench to any grounded metal part could cause a
severe spark, possibly resulting in personal
injury. Upon installation of the battery the positive
lead should be connected first.
GENERATOR
The generator is a three phase, field sensed unit. The
rotor and stator windings produce three phase
alternating current, AC, which is rectified to direct
current, DC. The electronic voltage regulator unit
controls the generator output voltage by high
frequency switching of the rotor field circuit. Use only
the correct Vehicle replacement fan belt. Occasionally
check that the engine and generator pulleys are
accurately aligned.
It is essential that good electrical connections are
maintained at all times. Of particular importance are
those in the charging circuit (including those at the
battery) which should be occasionally inspected to
see that they are clean and tight. In this way any
significant increase in circuit resistance can be
prevented.Do not disconnect battery cables while the engine is
running or damage to the semi-conductor devices
may occur. It is also inadvisable to break or make any
connections in the generator charging and control
circuits while the engine is running.
The electronic voltage regulator employs micro-circuit
techniques resulting in improved performance under
difficult service conditions. The whole assembly is
encapsulated in silicone rubber and housed in an
aluminium heat sink, ensuring complete protection
against the adverse effects of temperature, dust, and
moisture etc.
The regulating voltage is set during manufacture to
give the required regulating voltage range of 14.2±
0.2 volts, and no adjustment is necessary. The only
maintenance needed is the occasional check on
terminal connections and wiping with a clean dry
cloth.
The generator system provides for direct connection
of a charge (ignition) indicator warning light, and
eliminates the need for a field switching relay or
warning light control unit. As the warning lamp is
connected in the charging circuit, lamp failure will
cause loss of charge. Lamp should be checked
regularly and spare carried.
When using rapid charge equipment to re-charge the
battery, the battery must be disconnected from the
vehicle.
NOTE: For description and operation of
electrical circuits see separate publication:
Electrical Troubleshooting Manual.
