INFORMATION GENERAL FITTING REMINDERS
WORKSHOP SAFETY IS YOUR RESPONSIBILITY!
The suggestions, cautions and warnings in the
section are intended to serve as reminders for
trained and experienced mechanics. This manual
is not a course in automotive mechanics or
workshop safety.
Shop equipment, shop environment, and the use
and disposal of solvents, fluids, and chemicals
are subject to government regulations which are
intended to provide a level of safety. It is your
responsibility to know and comply with such
regulations.
PRECAUTIONS AGAINST DAMAGE
1.Always fit covers to protect fenders before
commencing work in engine compartment.
2.Cover seats and carpets, wear clean overalls
and wash hands or wear gloves before working
inside vehicle.
3.Avoid spilling hydraulic fluid or battery acid on
paint work. Wash off with water immediately if
this occurs. Use Polythene sheets to protect
carpets and seats.
4.Always use a recommended Service Tool, or a
satisfactory equivalent, where specified.
5.Protect temporarily exposed screw threads by
replacing nuts or fitting plastic caps.SAFETY PRECAUTIONS
1.Whenever possible use a lift or pit when working
beneath vehicle, in preference to jacking. Chock
wheels as well as applying parking brake.
WARNING: Do not use a pit when
removing fuel system components.
2.Never rely on a jack alone to support vehicle.
Use axle stands carefully placed at jacking
points to provide rigid support.
3.Ensure that a suitable form of fire extinguisher is
conveniently located.
4.Check that any lifting equipment used has
adequate capacity and is fully serviceable.
5.Disconnect battery negative lead.
WARNING: Do not disconnect any pipes in
air conditioning refrigeration system,
unless trained and instructed to do so. A
refrigerant is used which can cause blindness if
allowed to contact eyes.
6.Ensure that adequate ventilation is provided
when volatile degreasing agents are being used.
7.Do not apply heat in an attempt to free stiff nuts
or fittings; as well as causing damage to
protective coatings, there is a risk of damage to
electronic equipment and brake linings from
stray heat.

WHEELS AND TYRES
5
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.
