INFORMATION DYNAMOMETER TESTING - VEHICLES WITH
ANTI-LOCK BRAKES (ABS)
WARNING: Do not attempt to test ABS
function on a dynamometer
Four wheel dynamometers
NOTE: Before testing a vehicle on a four
wheel dynamometer disconnect the valve
relay.
See Electrical Trouble Shooting
Manual.
The ABS function will not work, the ABS warning
light will illuminate. Normal braking will be
available.
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.
Two wheel dynamometers
IMPORTANT: Use a four wheel dynamometer for
brake testing if possible.
NOTE: ABS will not function on a two
wheel dynamometer. The ABS light will
illuminate during testing. Normal braking
will be available.
If brake testing on a single rig is necessary it must be
carried out with propeller shaft to the rear axle
removed, AND neutral selected in BOTH main and
transfer boxes.
If checking engine performance, the transfer box must
be in high range and drive shaft to stationary axle
removed.
TOWING
CAUTION: The vehicle has permanent
four-wheel drive. The following towing
instructions must be adhered to:
Towing the vehicle on all four wheels with driver
operating steering and brakes.
1.Turn ignition key turn to position '1' to release
steering lock.
2.Select neutral in main gearbox and transfer
gearbox.
3.Secure tow rope, chain or cable to towing eye.
4.Release the parking brake.
CAUTION: The brake servo and power
assisted steering system will not be
functional without the engine running.
Greater pedal pressure will be required to apply
the brakes, the steering system will require
greater effort to turn the front road wheels.
The vehicle tow connection should be used only
in normal road conditions, 'snatch' recovery
should be avoided.
Suspended tow by breakdown vehicle
CAUTION: To prevent vehicle damage,
front or rear propeller shaft MUST BE
removed, dependent upon which axle is
being trailed.
1.Mark propeller shaft drive flanges at transfer
gearbox and axles with identification lines to
enable the propeller shaft to be refitted in its
original position.
2.Remove the propeller shaft fixings, remove the
shaft from the vehicle.
3.If the front axle is to be trailed turn ignition key to
position '1' to release steering lock.
CAUTION: The steering wheel and/or
linkage must be secured in a straight
ahead position. DO NOT use the steering
lock mechanism for this purpose.

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 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.
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.

TIMING BELT
Remove
1.Remove front cover plate.
See Front Cover

2.Position engine at TDC on No. 1 cylinder.
3.If manual gearbox: Remove blanking plug from
flywheel housing and insert timing tool
LRT-12-044. If EDC - timing tool LRT-12-085
must be used.
If automatic gearbox:Sited to the rear of the
engine sump on engine backplate is a blanking
plate. Remove 2 blanking plate bolts and insert
timing tool LRT-12-044 into the larger bolt hole.
4.Engage timing tool pin with slot in flywheel.
5.Check correct alignment of timing mark on
camshaft gear and that crankshaft key aligns
with cast arrow on housing.
6.Insert pin from special tool LRT-12-045 in
injection pump gear and through into pump
flange.
NOTE: If the camshaft gear is to be
removed during these operations its
retaining bolt should be slackened before
the timing belt is removed.
7.Slacken belt tensioner bolt.
8.Remove idler pulley.
9.Remove timing belt.
NOTE: During use, a belt develops a wear
pattern relative to its running direction, if
the original belt is to be re-used it must be
refitted so that it rotates in the original direction.
CAUTION: Belts must be stored on edge
on a clean surface and in such a manner
that bends are not less than 50 mm radius.
Do not bend belts at an acute angle or radius of
less than 50 mm, otherwise premature failure
could result.
10.Mark belt direction of rotation, using soft chalk,
to ensure correct refitment.

DESCRIPTION AND OPERATION Distributor and timing chain lubrication
The distributor and timing chain are lubricated from
the camshaft front bearing. The feed to the timing
chain is channelled along the camshaft sprocket, key
and spacer where it sprays onto the chain.

6. Spring
7. Outer sleeve
8. Lower chamber - high pressure
The purpose of the hydraulic tappet is to provide
maintenance free and quiet operation of the inlet and
exhaust valves. It achieves its designed purpose by
utilizing engine oil pressure to eliminate the
mechanical clearance between the rockers and the
valve stems.
During normal operation, engine oil pressure present
in the upper chamber 4, passes through the
non-return ball valve 5 and into the lower (high
pressure) chamber 8.
When the cam begins to lift the outer sleeve 7, the
resistance of the cylinder valve spring felt through the
pushrod seat 2, causes the inner sleeve 3, to move
downwards inside the outer. This slight downward
movement of the inner sleeve closes the ball valve 5
and increases the hydraulic pressure in the high
pressure chamber, sufficient to ensure that the push
rod opens the valve fully.
As the tappet assembly moves off the peak of the cam
the ball valve 5 opens to equalize the pressure in both
chambers which ensures that the valve fully closes
when the tappet is on the back of the cam.
