Self-locking bolts and screws
Self-locking bolts and screws, i.e. nylon patched or
trilobular thread can be re-used providing resistance
can be felt when the locking portion enters the
female thread.
Nylon patched bolts and screws have a locking agent
pre-applied to the threads. They are identified by the
presence of a coloured section of thread which
extends for up to 180° around the thread.
Trilobular bolts (i.e. Powerlok) have a special thread
form which creates a slight interference in the
tapped hole or threads of the nut into which it is
screwed.
DO NOT re-use self-locking fasteners in critical
locations (e.g. engine bearings, flywheel). Always
use the correct replacement self-locking nut, bolt or
screw.
DO NOT fit non self-locking fasteners in applications
where a self-locking nut, bolt or screw is specified.
Nut identification
Nut identification
A nut with an ISO metric thread is marked on one
face or on one of the flats of the hexagon with the
strength grade symbol 8, 12, or 14. Some nuts with a
strength grade 4, 5 or 6 are also marked and some
have the metric symbol M on the flat opposite the
strength grade marking.
A clock face system is sometimes used as an
alternative method of indicating the strength grade.
The external chamfers or a face of the nut is marked
in a position relative to the appropriate 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.
When tightening a slotted or castellated nut, never
loosen it to insert a split pin except where
recommended as part of an adjustment. If difficulty is
experienced, alternative washers or nuts should be
selected, or the washer thickness reduced.
Where bearing pre-load is involved, nuts should be
tightened in accordance with special instructions.

GENERAL INFORMATION
03-16
'Oetiker' clips may be removed by bending the tag
(arrowed) and releasing the free end of the clip. Clips
must not be re-used. When fitting new clips, ensure
the clip is correctly positioned on the hose before
tightening and that when the clip is tightened, the tag
is located in the longitudinal slot in the free end of the
clip (arrowed in illustration).
Heat protection
Always ensure that heatshields and protective
sheathing are in good condition. Replace if damage
is evident.
Particular care must be taken when routing hoses
close to hot engine components, such as the exhaust
manifold and the Exhaust Gas Recirculation (EGR)
pipe.
Hoses will relax and deflect slightly when hot; ensure
this movement is taken into account when routing
and securing hoses.
Service tools
General
Special service tools have been developed to
facilitate removal, dismantling and assembly of
mechanical components in a cost effective and time
efficient manner. The use of such special tools also
helps prevent the potential for damage to
components.
Some operations described in this Manual cannot be
carried out properly without the aid of the relevant
service tools.

Rolling road testing
General
IMPORTANT: Use a four wheel rolling road for
brake testing if possible.
The front and rear wheels cannot be driven
independently due to the viscous coupling. This
eliminates the need for differential lock by
progressively applying more torque to the rear
wheels if the front wheels start to slip.
DO NOT attempt to drive individual wheels with
vehicle supported on floor jacks or stands.
Four wheel rolling road
Provided that front and rear rollers are rotating at
identical speeds and that normal workshop safety
standards are applied, there is no speed restriction
during testing, except any that may apply to the tyres.
Before testing a vehicle with anti-lock brakes on a
four wheel rolling road, disconnect the ABS
modulator. The ABS function will not work, the ABS
warning light will illuminate. Normal braking will be
available.
Two wheel rolling road
ABS will not function on a two wheel rolling road. The
ABS light will illuminate during testing. Normal
braking will be available.
If brake testing on a two wheel rolling road is
necessary, the following precautions should be
taken:
lpropeller shaft to the rear axle is removed/
disconnected;
lneutral selected in gearbox;
lhill descent control not selected.
When checking brakes, run engine at idle speed to
maintain servo vacuum.

Fuel handling precautions
Fuel vapour is highly inflammable and in confined
spaces is also explosive and toxic. The vapour is
heavier than air and will always fall to the lowest
level. The vapour can easily be distributed
throughout a workshop by air currents;
consequently, even a small spillage of fuel is
potentially very dangerous.
The following information provides basic precautions
which must be observed if petrol (gasoline) is to be
handled safely. It also outlines other areas of risk
which must not be ignored. This information is issued
for basic guidance only, if in doubt consult your local
Fire Officer.
General
Always have a fire extinguisher containing FOAM,
CO
2, GAS or POWDER close at hand when handling
or draining fuel or when dismantling fuel systems.
Fire extinguishers should also be located in areas
where fuel containers are stored.
Always disconnect the vehicle battery before
carrying out dismantling or draining work on a fuel
system.
Whenever fuel is being handled, drained or stored, or
when fuel systems are being dismantled, all forms of
ignition must be extinguished or removed; any
leadlamps must be flameproof and kept clear of
spillage.
WARNING: No one should be permitted to repair
components associated with fuel without first
having specialist training.
WARNING: Do not remove fuel system
components while the vehicle is over a pit.Fuel tank draining
Fuel tank draining should be carried out in
accordance with the procedure outlined in the FUEL
DELIVERY section of this manual and observing the
following precautions:
WARNING: Fuel must not be extracted or drained
from any vehicle while it is over a pit. Extraction
or draining of fuel must be carried out in a well
ventilated area.
The capacity of containers must be more than
adequate for the amount of fuel to be extracted or
drained. The container should be clearly marked
with its contents and placed in a safe storage
area which meets the requirements of local
authority regulations.
WARNING: When fuel has been drained from a
fuel tank the precautions governing naked lights
and ignition sources should be maintained.
Fuel tank removal
When the fuel line is secured to the fuel tank outlet by
a spring steel clip, the clip must be released before
the fuel line is disconnected or the fuel tank is
removed. This procedure will avoid the possibility of
residual petrol fumes in the fuel tank being ignited
when the clip is released.
As an added precaution, fuel tanks should have a
'FUEL VAPOUR' warning label attached to them as
soon as they are removed from the vehicle.
Fuel tank repairs
No attempt should be made to repair a plastic fuel
tank. If the structure of the tank is damaged, a new
tank must be fitted.
Body repairs
Plastic fuel pipes are particularly susceptible to heat,
even at relatively low temperature, and can be
melted by heat conducted from some distance away.
When body repairs involve the use of heat, all fuel
pipes which run in the vicinity of the repair area must
be removed, and the tank outlet plugged.
