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.

MAINTENANCE STEERING BALL JOINTS
1.Check for wear in joints by moving ball joint up
and down vigorously. If free movement is
apparent, fit a new joint assembly.
2.Check condition of steering ball joints paying
particular attention to dust covers.
NOTE: Any requirement to replace the
steering ball joints should be advised to
the customer as this will incur additional
labour and/or material cost and should not be
carried out without the authorisation of the
customer.
NOTE: Ball joints are lubricated for life
during manufacture and require no further
lubrication unless the rubber boot has
been dislodged or damaged. All joints should be
checked at specified service intervals, but more
frequently if vehicle is used under arduous
conditions.

DESCRIPTION AND OPERATION IN-LINE AIR FILTER - PRE EU´ u MODELS
1.To modulator vent port
2.Filter element3.To atmosphere
The in-line air filter is placed in the ventilation line from the EGR modulator. The modulator needs to be able to
vent to atmosphere in order to release the vacuum supplied to the EGR valve. The filter prevents contamination
entering the modulator via the vent port which could cause failure. The filter should be periodically changed in
accordance with the recommended service intervals. The filter is attached to the RH inner front wing, and is held
in position by a clamping bracket. The filter must be mounted vertically.
NOTE: EU3 models are not fitted with an in-line air filter. The ventilation line connects directly to
the air cleaner housing, where it vents to atmosphere.

DESCRIPTION AND OPERATION The dual mass flywheel is bolted on the rear of the crankshaft with eight bolts. A dowel on the crankshaft flange
ensures that the flywheel is correctly located. A ring gear is fitted on the outer diameter of the flywheel. The ring
gear is not serviceable. Thirty blind holes are drilled in the outer diameter of the flywheel adjacent to the ring gear.
The holes are positioned at 10°intervals with four 20°spaces. The holes are used by the crankshaft position
sensor for engine management.
The dual mass flywheel is used to insulate the gearbox from torsional and transient vibrations produced by the
engine. The flywheel comprises primary and secondary flywheels with the drive between the two transferred by a
torsional damper which comprises four coil springs. The springs are located in the inside diameter of the primary
flywheel. Two of the springs are of smaller diameter and fit inside the larger diameter springs.
The primary flywheel locates the ring gear and is attached to the crankshaft flange with eight bolts. The two pairs
of coil springs are located in a recess in the flywheel between two riveted retainers. A roller bearing is pressed
onto the central boss of the primary flywheel and retained with a riveted plate. The bearing provides the mounting
for the secondary flywheel.
The secondary flywheel comprises two parts; an outer flywheel which provides the friction surface for the clutch
drive plate and an inner drive plate which transfers the drive from the primary flywheel, via the coil springs, to the
outer flywheel. The two components of the secondary flywheel are secured to each other with rivets. The inner
drive plate is located between the two pairs of coil springs and can rotate on the ball bearing in either direction
against the combined compression force of the four coil springs. Under high torque loading conditions the
secondary flywheel can rotate in either direction up to 70°in relation to the primary flywheel.
The operating face of the secondary flywheel is machined to provide a smooth surface for the drive plate to
engage on. Three dowels and six studs and nuts provide for the location and attachment of the pressure plate.
