fittings must be checked, especially
the tightness of bolts, including the U-
bolts and spring shackles. The rear
leaf springs should be lightly treated
with engine oil, especially at the tips
of the leaves.
Caution: Do not allow oil to come in
contact with the rubber bushes, as this
will cause the rubber to brake down. If
the bushes need lubrication use a
rubber safe lubricant such as P.T.F.E.
Chassis
At the same time as the suspension is
being checked, the chassis and frame
front should be examined for damage
and the tightness of fittings. It is
recommended that some form of
corrosion protection is used regularly
to aid that used in production. Old
engine oil or modern wax treatments
may help extend the already long life
of underbody parts.
Warning: Care should be taken in the
use of underbody treatments as they
may contain harmful solvents. Read
instructions carefully.
Never work under a car supported
only by a jack. Your dealer will
recommend suitable treatments for
the underside of your car.
Wheels and Tyres
Tyre Pressures
Tyre pressures should be checked at
least every week and at every service.
The maximum life and performance
will only be obtained by correct
maintenance.
For normal use the tyres should be set
at 22lb/in
2
or 1.5 BAR on all four road
wheels and the spare.
For long term high speed work or
competition you should contact your
dealer or the factory for alternative
pressure settings.
Warning: You are legally required to
maintain your tyres to a good
servicable standard.
You should only use the
recommended wheels, wheel
fasteners and tyres fitted to the correct
standard.
Tyres must be replaced with those of
the same specification and quality
originally fitted.
Do not drive on tyres or wheels
showing any sign of wear or damage.
Tyres must be replaced as soon as the
wear indicator in the tread is level
with any part of the tread. Worn tyres
are dangerous, especially on a
performance car. They may cause
changes in the handling, particularly
in wet conditions. Always maintain the
correct pressures and wheel
alignment. Always check pressure
when the tyres are cold.
Valves and Caps
Always refit valve caps and screw
down firmly by hand. They prevent
dirt entering the valve and help to
seal it.
Tyre Care
Check tyres as often as possible, avoid
contact with hard objects, i.e. kerbs,
pot holes etc. as these may damage
the tread or tyre cords. Avoid contact
with oil, petrol, paraffin and brake
fluid as these may damage the rubber.
Always remove flint or sharp objects
from the tread as these may work into
the tyre and cause damage.
Wear Indicator
The original tyres fitted to your car
have wear indicators in the tread
pattern. These will appear as a bar
across the pattern when 1.5mm of
tread is left. The tyre must be replaced
when these appear.
