GENERAL FITTING REMINDERS

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 back 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.

REMOVE WHEELS, CHECK TYRES
Check tyres (including spare) for compliance with
manufacturers' specification.
Check visually for cuts, lumps, bulges, uneven tread
wear and tread depth. Check road wheels for
damage.
Check/adjust tyre pressures.
CHECK/TIGHTEN TOWING BRACKET FITTINGSINSPECT BRAKE PADS FOR WEAR, CALIPERS
FOR LEAKS AND CONDITION
Check thickness of brake pads, fit new pads if
minimum thickness is less than 3,0mm. Check brake
pads for oil contamination. If new brake pads required.
See BRAKES, Repair, Front Brake Pads
or.See BRAKES, Repair, Rear Brake Pads
WARNING: When renewing brake pads, it
is essential that only genuine components
with correct grade of lining are used.
Always fit new pads as complete axle sets, NEVER
individually or as a single wheel set. Serious
consequences could result from out of balance
braking due to mixing of linings.
Refit road wheels
Fit road wheels in original hub position. Secure in
position with wheel nuts, do not fully tighten wheel
nuts at this stage, lower vehicle and finally tighten
wheel nuts to correct torque.

REPAIR Timing belt fitting and tensioning
NOTE: It is important that belt tensioning
is carried out carefully and accurately. The
following procedure involves tensioning
the belt twice to ensure that it is equally tensioned
between each gear. New and original belts are
tensioned to different figures.

from special tool LRT-12-045 is correctly
inserted in injection pump gear and timing tool
LRT-12-044 (LRT-12-085 if EDC) is fitted to
flywheel housing with pin located in flywheel slot.
Or if automatic: Timing tool LRT-12-044 is fitted
to engine backplate and pin located in ring gear.

NOTE: Belt tensioning should be carried
out using a dial type torque meter having a
range not exceeding
60 Nm.The torque
meter should be used in the almost vertical
position.
35.Apply a tension of
14 to 16 Nmfor a new belt or

NOTE: The bearing bush can be removed
by using one of the following methods.
Method 1.
Obtain a short length of steel rod of a diameter having
a good slide fit in the bore of the bush. Pack the bore
with grease and insert the steel rod into the end of the
bore, give a sharp blow with a hammer and the
grease should drive out the bush. It is recommended
that the bush and rod be covered by a suitable cloth
or rag to prevent grease from splashing.
