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 definitive guide to 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 where
specified.
5.Protect temporarily exposed screw threads by
replacing nuts or fitting plastic caps.SAFETY PRECAUTIONS
1.Whenever possible, use a lift 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.
WARNING: Do not disconnect any pipes in
air conditioning 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
fixings; as well as causing damage to protective
coatings, there is a risk of damage to electronic
equipment and brake linings from stray heat.

INFORMATION PREPARATION
1.Clean components and surrounding area prior to
removal.
2.Blank off any openings exposed by component
removal using greaseproof paper and masking
tape.
3.Immediately seal fuel, oil or hydraulic lines when
separated, using plastic caps or plugs, to
prevent loss of fluid and entry of dirt.
4.Close open ends of oilways, exposed by
component removal, with tapered hardwood
plugs or readily visible plastic plugs.
5.Immediately a component is removed, place it in
a suitable container; use a separate container for
each component and its associated parts.
6.Before dismantling a component, clean it
thoroughly with a recommended cleaning agent;
check that agent is suitable for all materials of
component.
7.Clean bench and provide marking materials,
labels, containers and locking wire before
dismantling a component.
DISMANTLING
1.Observe scrupulous cleanliness when
dismantling components, particularly when
brake, fuel or hydraulic system parts are being
worked on. A particle of dirt or a cloth fragment
could cause a dangerous malfunction if trapped
in these systems.
2.Blow out all tapped holes, crevices, oilways and
fluid passages with an air line. Ensure that any
O-rings used for sealing are correctly replaced or
renewed, if disturbed.
3.Use marking ink to identify mating parts, to
ensure correct reassembly. If a centre punch or
scriber is used they may initiate cracks or
distortion of components.
4.Wire together mating parts where necessary to
prevent accidental interchange (e.g. roller
bearing components).
5.Wire labels on to all parts which are to be
renewed, and to parts requiring further
inspection before being passed for reassembly;
place these parts in separate containers from
those containing parts for rebuild.
6.Do not discard a part due for renewal until it has
been compared with the new part, to ensure that
its correct replacement has been obtained.INSPECTION-GENERAL
1.Never inspect a component for wear or
dimensional check unless it is absolutely clean;
a slight smear of grease can conceal an incipient
failure.
2.When a component is to be checked
dimensionally against figures quoted for it, use
correct equipment (surface plates, micrometers,
dial gauges, etc.) in serviceable condition.
Makeshift checking equipment can be
dangerous.
3.Reject a component if its dimensions are outside
limits quoted, or if damage is apparent. A part
may, however, be refitted if its critical dimension
is exactly limit size, and is otherwise satisfactory.
4.Use 'Plastigauge' 12 Type PG-1 for checking
bearing surface clearances. Directions for its
use, and a scale giving bearing clearances in
0,0025 mm steps are provided with it.

INFORMATION JOINTS AND JOINT FACES
1.Always use correct gaskets where they are
specified.
2.Use jointing compound only when
recommended. Otherwise fit joints dry.
3.When jointing compound is used, apply in a thin
uniform film to metal surfaces; take great care to
prevent it from entering oilways, pipes or blind
tapped holes.
4.Remove all traces of old jointing materials prior
to reassembly. Do not use a tool which could
damage joint faces.
5.Inspect joint faces for scratches or burrs and
remove with a fine file or oil stone; do not allow
removed material or dirt to enter tapped holes or
enclosed parts.
6.Blow out any pipes, channels or crevices with
compressed air, fit new 'O' rings or seals
displaced by air blast.FLEXIBLE HYDRAULIC PIPES, HOSES
1.Before removing any brake or power steering
hose, clean end fittings and area surrounding
them as thoroughly as possible.
2.Obtain appropriate plugs or caps before
detaching hose end fittings, so that ports can be
immediately covered to exclude dirt.
3.Clean hose externally and blow through with
airline. Examine carefully for cracks, separation
of plies, security of end fittings and external
damage. Reject any hose found faulty.
4.When refitting hose, ensure that no unnecessary
bends are introduced, and that hose is not
twisted before or during tightening of union nuts.
5.Containers for hydraulic fluid must be kept
absolutely clean.
6.Do not store brake fluid in an unsealed
container. It will absorb water, and fluid in this
condition would be dangerous to use due to a
lowering of its boiling point.
7.Do not allow brake fluid to be contaminated with
mineral oil, or use a container which has
previously contained mineral oil.
8.Do not re-use brake fluid bled from system.
9.Always use clean brake fluid to clean hydraulic
components.
10.Fit a cap to seal a hydraulic union and a plug to
its socket after removal to prevent ingress of dirt.
11.Absolute cleanliness must be observed with
hydraulic components at all times.
12.After any work on hydraulic systems, inspect
carefully for leaks underneath the vehicle while a
second operator applies maximum pressure to
the brakes (engine running) and operates the
steering.

INFORMATION COTTER PINS
1.Fit new cotter pins throughout when replacing
any unit.
2.Always fit cotter pins where cotter pins were
originally used. Do not substitute spring
washers: there is always a good reason for the
use of a cotter pin.
3.All cotter pins should be fitted as shown unless
otherwise stated.
NUTS
1.When tightening a slotted or castellated nut
never loosen it to insert cotter pin or locking wire
except in those recommended cases where this
forms part of an adjustment. If difficulty is
experienced, alternative washers or nuts should
be selected, or washer thickness reduced.
2.Where self-locking nuts have been removed it is
advisable to replace them with new ones of the
same type.
NOTE: Where bearing pre-load is involved
nuts should be tightened in accordance
with special instructions.
LOCKING WIRE
1.Fit new locking wire of the correct type for all
assemblies incorporating it.
2.Arrange wire so that its tension tends to tighten
the bolt heads, or nuts, to which it is fitted.SCREW THREADS
1.Both UNF and Metric threads to ISO standards
are used. See below for thread identification.
2.Damaged threads must always be discarded.
Cleaning up threads with a die or tap impairs the
strength and closeness of fit of the threads and
is not recommended.
3.Always ensure that replacement bolts are at
least equal in strength to those replaced.
4.Do not allow oil, grease or jointing compound to
enter blind threaded holes. The hydraulic action
on screwing in the bolt or stud could split the
housing.
5.Always tighten a nut or bolt to the recommended
torque value. Damaged or corroded threads can
affect the torque reading.
6.To check or re-tighten a bolt or screw to a
specified torque value first loosen a quarter of a
turn, then re-tighten to the correct value.
7.Oil thread lightly before tightening to ensure a
free running thread, except in the case of
threads treated with sealant/lubricant, and
self-locking nuts.
UNIFIED THREAD IDENTIFICATION
1. Bolts
A circular recess is stamped in the upper surface
of the bolt head.
2. Nuts
A continuous line of circles is indented on one of
the flats of the hexagon, parallel to the axis of
the nut.
3. Studs, Brake Rods, etc.
The component is reduced to the core diameter
for a short length at its extremity.

Compressor Oil Sanden oil
LUBRICATION PRACTICE
Use a high quality oil of the correct viscosity range and service classification in the engine during maintenance and
when topping up. The use of oil not to the correct specification can lead to high oil and fuel consumption and
ultimately to damaged components.
Oil to the correct specification contains additives which disperse the corrosive acids formed by combustion and
prevent the formation of sludge which can block the oilways. Additional oil additives should not be used. Always
adhere to the recommended servicing intervals.
WARNING: Many liquids and other substances used in motor vehicles are poisonous. They must
not be consumed and must be kept away from open wounds. These substances, among others,
include anti-freeze, windscreen washer additives, lubricants and various adhesives.
