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 wings 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 ramp 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 negative (grounded) terminal of
vehicle battery.
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.

INFORMATION PREPARATION
1.Before removing a component, clean it and its
surrounding areas as thoroughly as possible.
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 after
comparing it with a 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 BALL AND ROLLER BEARINGS
CAUTION: Never refit a ball or roller
bearing without first ensuring that it is in a
fully serviceable condition.
1.Remove all traces of lubricant from bearing
under inspection by washing in a suitable
degreaser; maintain absolute cleanliness
throughout operations.
2.Inspect visually for markings of any form on
rolling elements, raceways, outer surface of
outer rings or inner surface of inner rings. Reject
any bearings found to be marked, since any
marking in these areas indicates onset of wear.
3.Holding inner race between finger and thumb of
one hand, spin outer race and check that it
revolves absolutely smoothly. Repeat, holding
outer race and spinning inner race.
4.Rotate outer ring gently with a reciprocating
motion, while holding inner ring; feel for any
check or obstruction to rotation, and reject
bearing if action is not perfectly smooth.
5.Lubricate bearing generously with lubricant
appropriate to installation.
6.Inspect shaft and bearing housing for
discoloration or other marking suggesting that
movement has taken place between bearing and
seatings. (This is particularly to be expected if
related markings were found in operation 2).
7.Ensure that shaft and housing are clean and free
from burrs before fitting bearing.8.If one bearing assembly of a pair shows an
imperfection it is generally advisable to replace
both with new bearings; an exception could be
made if the faulty bearing had covered a low
mileage, and it could be established that
damage was confined to it only.
9.When fitting bearing to shaft, apply force only to
inner ring of bearing, and only to outer ring when
fitting into housing. (Refer to ST1042M).
10.In the case of grease lubricated bearings (e.g.
hub bearings) fill space between bearing and
outer seal with recommended grade of grease
before fitting seal.
11.Always mark components of separable bearings
(e.g. taper roller bearings) in dismantling, to
ensure correct reassembly. Never fit new rollers
in a used outer ring, always fit a complete new
bearing assembly.

INFORMATION OIL SEALS
NOTE: Ensure that the seal running track
is free from pits, scores, corrosion and
general damage prior to fitting
replacement seal.
1.Always fit new oil seals when rebuilding an
assembly.
2.Carefully examine seal before fitting to ensure
that it is clean and undamaged.
3.Coat the sealing lips with clean grease; pack
dust excluder seals with grease, and heavily
grease duplex seals in cavity between sealing
lips.
4.Ensure that seal spring, if provided, is correctly
fitted.
5.Place lip of seal towards fluid to be sealed and
slide into position on shaft, using fitting sleeve
when possible to protect sealing lip from damage
by sharp corners, threads or splines. If fitting
sleeve is not available, use plastic tube or tape
to prevent damage to sealing lip.
6.Grease outside diameter of seal, place square to
housing recess and press into position, using
great care and if possible a bell piece to ensure
that seal is not tilted. (In some cases it may be
preferable to fit seal to housing before fitting to
shaft). Never let weight of unsupported shaft rest
in seal.
7.If correct service tool is not available, use a
suitable drift approximately 0.4mm (0.015 in)
smaller than outside diameter of seal. Use a
hammerVERY GENTLYon drift if a press is not
suitable.
8.Press or drift seal in to depth of housing if
housing is shouldered, or flush with face of
housing where no shoulder is provided. Ensure
that the seal does not enter the housing in a
tilted position.
NOTE: Most cases of failure or leakage of
oil seals are due to careless fitting, and
resulting damage to both seals and
sealing surfaces. Care in fitting is essential if
good results are to be obtained. NEVER use a seal
which has been improperly stored or handled,
such as hung on a hook or nail.

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 FUEL SYSTEM HOSES
CAUTION: All fuel hoses are made up of
two laminations, an armoured rubber outer
sleeve and an inner viton core. If any of
the fuel system hoses have been disconnected, it
is imperative that the internal bore is inspected to
ensure that the viton lining has not become
separated from the amoured outer sleeve. A new
hose must be fitted if separation is evident.
METRIC BOLT IDENTIFICATION
1.An ISO metric bolt or screw, made of steel and
larger than 6 mm in diameter can be identified by
either of the symbols ISO M or M embossed or
indented on top of the head.
2.In addition to marks to identify the manufacture,
the head is also marked with symbols to indicate
the strength grade, e.g. 8.8, 12.9 or 14.9, where
the first figure gives the minimum tensile
strength of the bolt material in tens of kgf/mm
2.
3.Zinc plated ISO metric bolts and nuts are
chromate passivated, a gold-bronze colour.
METRIC NUT IDENTIFICATION
1.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 4, 5 or 6 are also
marked and some have the metric symbol M on
the flat opposite the strength grade marking.
2.A clock face system is 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.
3.A dot is used to locate the 12 oclock position
and a dash to indicate the strength grade. If the
grade is above 12, two dots identify the 12
oclock position.
KEYS AND KEYWAYS
1.Remove burrs from edges of keyways with a fine
file and clean thoroughly before attempting to
refit key.
2.Clean and inspect key closely; keys are suitable
for refitting only if indistinguishable from new, as
any indentation may indicate the onset of wear.
TAB WASHERS
1.Fit new washers in all places where they are
used. Always fit a new tab washer.
2.Ensure that the new tab washer is of the same
design as that replaced. 
						

							GENERAL FITTING REMINDERS

INFORMATION SPLIT PINS
1.Fit new split pins throughout when replacing any
unit.
2.Always fit split pins where cotter pins were
originally used. Do not substitute spring
washers: there is always a good reason for the
use of a split pin.
3.All split pins should be fitted as shown unless
otherwise stated.
NUTS
1.When tightening a slotted or castellated nut
never loosen it back to insert split 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.
