Clean Notice Clean the engine before you start
engine maintenance. Obey the correct procedures.
Contamination of the fuel system will cause
damage and possible failure of the
engine. Notice The engine and other components
could be damaged by high pressure washing
systems. Special precautions must be taken if
the machine is to be washed using a high
pressure system. Make sure that the alternator,
starter motor and any other electrical
components are shielded and not directly cleaned
by the high pressure cleaning system. Do not aim
the water jet directly at bearings, oil seals or
the engine air induction system.
Drain and Fill
Refer to Engine, Oil Filter, (PIL 15-21-00).
- Before carrying out any service procedures that
require components to be removed, the engine must
be properly cleaned. - Cleaning must be carried out either in the area
of components to be removed or, in the case of
major work, or work on the fuel system, the
whole engine and surrounding machine must be
cleaned. - Stop the engine and allow it to cool for at least
one hour. DO NOT attempt to clean any part of
the engine while it is running. - Make sure that the electrical system is isolated.
- Make sure that all electrical connectors are
correctly coupled. If connectors are open fit the
correct caps or seal with water proof tape. - Cover the alternator with a plastic bag to
prevent water ingress. - Seal the engine air intake, exhaust and breather
system. - Make sure that the oil filler caps and dipstick
are correctly installed. - Use a low pressure water jet and soft bristle
brush to soak off caked mud or dirt. - Apply an approved cleaning and degreasing agent
with a brush. Obey the manufacturers
instructions. - Use a pressure washer to remove the soft dirt
and oil. Important DO NOT aim the water jet
directly at oil seals or electrical and
electronic components such as ECU (Electronic
Control Unit)'s, alternator or fuel injectors.
DO NOT place the jet nozzle closer than 600mm
(24 in) to any part of the engine or after
treatment system including exhaust sensor ECU
(if installed).

Maintenance The air conditioning system is a
closed loop system and contains pressurised
refrigerant. No part of the system should be
disconnected until the system has been
discharged by a refrigeration engineer or a
suitably trained person. You can be severely
frostbitten or injured by escaping refrigerant.
- When the pressure washing is complete move the
machine away from the wash area, or
alternatively, clean away the material washed
from the machine. - Before working on specific areas of the engine
use a compressed air jet to dry off any moisture.
When the area is dry use a soft clean brush to
remove any sand or grit particles that remain. - When removing components be aware of any dirt or
debris that may be exposed. Cover any open ports
and clean away the deposits before proceeding

Engine mounts support the engine and in some
cases the transmission, they dampen noise and
vibration. The mounts isolate the engine and
transmission from the chassis so that vibrations
and noise are not transmitted to the rest of the
machine.
Most engine mounts consist of metal attachment
plates and large rubber insulator blocks. The
rubber portions of the mount are flexible and
provide the cushioning that dampens the engine
vibrations. The metal bracket part of the mount
provides the mechanical support and attachment
points for the engine mounts.

Inspection
- Apply a layer of petroleum jelly to the grooves
in the bearing blocks, E-seals (x2) and back-up
seals (x2). This will keep the seals in place. - Keep the E-seals, flat side outwards, into the
front and rear bearing blocks. Carefully put the
backup seals with the flat side outwards, in the
respective groove made by the E-seal and the
groove in the bearing block. - Make sure that the notches in the back-up seals
and E-seals are lined up, so that the back-up
seal sits flush with the E-seal. - Keep the front housing, with the seal side facing
downwards on a clean flat surface. - Apply a thin layer of petroleum jelly to the
exposed face of the front bearing block.
- Clean and dry all the parts before you do an
inspection. - Inspect all O-ring grooves and shaft seal
recesses and make sure that there are no burrs. - Inspect the driveshaft for damage. Check for
marks or grooves on the driveshaft in the area
of the seal. Slight discolouration of the shaft
is permitted. - Inspect the faces of the gears for scoring or
excessive wear. If the face of the gear is sharp,
it can damage the bearing block. If you find any
signs of wear, replace the parts. - Inspect the bearing blocks for excessive wear or
scoring on the surfaces that are in contact with
the gears. - Inspect the bearing for excessive wear or
damage. - Inspect the area inside the gear housings. It is
normal for the surface inside the gear housing
to show a clean wipe on the surface of the
intake side. There should not be excessive wear
or scoring. - Replace the fan motor, if you find any of the
following defects - The gear cut-in track on the low pressure side
of the body is deeper than the specified or has
a scarred and matt appearance. - Dimension 0.08mm
- The PTFE (Polytetrafluoroethylene) coated
bearings in the body or flanges are worn through
so that the bronze base is visible. - The gear side faces or bearing blocks are
scarred. - The driveshaft has a wear groove where the shaft
seal lips run.
- Insert the drive end of the driveshaft through
the front bearing block with the seal side down,
and the open side of the E-seal pointing to the
intake side of the motor. - Install a sleeve over the driveshaft threads to
protect the shaft seal. Slide the driveshaft
carefully through the seal and then remove the
sleeve from the driveshaft. - Install the idler gear shaft into the remaining
position in the bearing block. - Apply a thin layer of clean hydraulic oil to the
face of the driveshaft and idler gears. - Keep the rear bearing block on the driveshaft and
idler gear shafts with the seals facing upwards
and the open ends of the E-seals facing the
intake side of the motor. - Make sure that the dowel pins are in place in
the gear housing. On later housings there are
two long dowels through the housing that locate
in the front mounting flange and the rear cover.
These replace the four short dowels. - Apply a layer of petroleum jelly to the seal
grooves in both sides of the gear housing. - Apply a thin layer of petroleum jelly on the O-
ring1 and O-ring2 and install them in the gear
housing. - Move the gear housing downward over the rear
bearing block until the dowel pins come in
contact with their respective bores in the front
housing. - Press the housing together with your hands. Do
not force or use any tool. - Make sure that the intake port in the housing is
on the same side as the open end of the rear E-
seal and that the marks made on the housing are
aligned.
Assemble
- Wash all the components in a suitable aromatic
solvent. When dry apply hydraulic fluid
immediately to prevent moisture collecting. - Install a new shaft seal into the front housing,
with the part number of the seal facing outwards.
Press the new seal into its bore until it fully
seats. - Install the circlip into its groove in the front
housing. - Keep the front and rear bearing blocks on a
clean work bench with the E-seal grooves facing
upwards.

2321 - Cooling System 05 - Fan Motor 00 - General
- The surface of the rear bearing block should be
slightly below the face of the gear housing. If
the bearing block sits higher than the rear face
of the housing then the E-seal or O-ring may
have become detached from its seat and maybe
trapped. Remove the housing and check the seals
for correct installation. - Install the rear housing onto the dowels in the
housing. Make sure that the marks made on the
housing are aligned and press the housing
together with hand pressure only. - Install the bolts (x4) and washers (x4).
