SECTION 4 - LUBRICATION AND MAINTENANCE
• The paddle play at the top of the grain
elevator
The functionality of the flow sensor is affected by the
play between the clean grain elevator paddles and
the top of the clean grain elevator. Due to paddle wear
it will be necessary to adjust this distance into the
range of 2 - 3 mm (5/64” - 1/8”).
To check paddle tip play, proceed as follows:
1. Open the grain tank covers (if installed)
2. Remove cover 1.
188
3. Open fast coupler 2 on top and swing the sensor
open to the front of the combine.
189
4. Check now distance “X” at position 5 indicated on
the side of the elevator head
(see fig.
187)
between the paddles and top of clean grain
elevator. At the top left and right side of the grain
elevator the distance between paddle tip in its
vertical position with the top edge of the elevator
housing may be not larger than 3 mm (1/8”) but
not smaller than 1 mm (5/128”). Turn the sprocket
by hand to bring the paddle in this position.
IMPORTANT: This job must be checked annually
before the beginning of the season.
5. To adjust paddle tip play. Contact your local
dealer to carry out this job.

SECTION 4 - LUBRICATION AND MAINTENANCE
HYDRAULIC EQUIPMENT
Hydraulic hoses are an important safety element in
modern machinery. However, hose characteristics
alter under pressure, thermal and UV light load over
the years. Therefore, most hoses now have a
production date printed on the metal clamp bushing
which allows to determine the age.
Legislation in certain countries and good practice
require that hydraulic hoses are replaced when they
become 6 years old.
DANGER
Escaping fluid under pressure can penetrate the skin
causing serious injury.
Avoid the hazard by relieving pressure before
disconnecting hydraulic or other lines.
Tighten all connections before applying pressure.
Search for leaks with a piece of cardboard. Protect
hands and body from high pressure fluids.
If an accident occurs, call for a doctor immediately.
Any fluid injected into the skin must be surgically
removed within a few hours. If not, gangrene may
result. Doctors unfamiliar with this type of injury
should refer to a knowledgeable medical source.
IMPORTANT: The hydraulic valves on the right-hand
side can always be operated manually in case of an
electric failure.
Push on the rubber caps of the solenoids to actuate
the hydraulic valve.

SECTION 4 - LUBRICATION AND MAINTENANCE
TRACKS (IF INSTALLED)
To use the tracks in optimal conditions, proceed as
follows:
1. Check regulary the hanging down of the chain.
2. Place a straight bar on top at the backside of the
chain as shown.
3. The distance between the bar and the lowest
place of the chain should be between
20 and 35 mm (3/4” and 3/8”).
191
In case of doubt or deviation from the required
tensioning, check and adjust tensioning as follows:
1. If there is no manometer installed, loosen the nut
2 of the valve located under the main valve at the
left-hand side behind the steering platform.
2. Turn the Allen screw counter-clockwise a few
turns to release the pressure.
192
3. Connect a manometer at 1 (1/4”).
4. Close the Allen screw again (clockwise) and
tighten the nut 2 (fig. 192).
5. Activate the unloading tube “swing in” rocker
button while driving a few times forward and
reverse with the combine:
The pressure on the manometer should be read
between 45 and 55 bar (653 and 798 psi).
193

6. If not ok, loosen the nut 3.
7. Turn the Allen screw a quarter by quarter and
repeat the procedure until the pressure is
obtained (45 to 55 bar).
Clockwise to increase the pressure
Counter-clockwise to decrease the pressure
8. After adjusting, tigthen the nut 3.
194
NOTE: To remove the manometer from the valve,
release again the pressure at 2 (fig. 192). Afterwards
activate the unloading tube “swing in” rocker button
while driving a few times forward and reverse with the
combine.

SECTION 4 - LUBRICATION AND MAINTENANCE
STEERING AXLE
There are three types of steering axles:
• Fixed steering axle
• Heavy Duty Adjustable Steering Axle
(H.D.A.S.A.)
• Power Rear Axle (P.R.A.)
To get a good adjustment of the steering axle, carry
out the following adjustments in these sequence.
1. Steering axle position
2. Axial position of the steering axle
(only H.D.A.S.A. and P.R.A.)
3. Height position (only H.D.A.S.A. and P.R.A.)
4. Track width position (only H.D.A.S.A. and P.R.A.)
5. Toe-in adjustment
6. Steering cylinder adjustment
4-83
SECTION 4 - LUBRICATION AND MAINTENANCE
1. Steering axle position
The steering axle should always be installed in the
upper hole 1 in the frame, except when working on
tracks.
When operating on tracks (and rice steering wheels),
the steering axle should be fitted in the lower hole 2
in the frame.
We recommend this job to be carried out by your
New Holland dealer.
195
2. Axial position of the steering axle
The complete steering axle must be axial
repositioned to the frame, depending on the size of
the steering wheels.
When bushing 2 is fitted at the rear of the steering
axle, then the steering axle is in the front (F) position.
If the bushing is at the front, then the steering axle is
in the rear (R) position.
Figure 197 shows the rear position, figure 198 the
front position.

BATTERIES
The combine is equipped with two 12 Volt batteries
(92 Ah). These are located at the back of the left-hand
side of the combine. Open cover 1 to have access to
the batteries.
The batteries can be disconnected completely by
means of the main battery switch 2.
IMPORTANT: To avoid loss of harvest data from the
InfoViewt monitor, engine power reduction and/or
permanent InfoViewt monitor damage, it is strongly
recommended not to stop the engine by using the
battery switch. Always use the contact key in this
case.
214
IMPORTANT: It is advisable to disconnect the
batteries at the end of the day using the battery
switch.
The earth cable is connected to the negative (-)
battery terminals.
Check the acid level weekly (every 50 operating
hours), and, if necessary, fill with distilled water until
the separators are covered.
215
NOTE: Models CX860 and CX880 are also equipped
with two 12V batteries (92Ah), connected parallel, but
switching to 24 V during starting.
216
4-113
SECTION 4 - LUBRICATION AND MAINTENANCE
Important tips
1. In cold weather, add water to the batteries just
before starting the engine. By doing this, the
water and the electrolyte will be mixed by the
charging current, thus avoiding freezing.
CAUTION
Keep sparks, lighted matches or an open flame away
from the battery as battery gas can explode.
Never check the battery charge by placing a metal
object across the terminals. Use a voltmeter or a
hydrometer.
2.
If the engine is reluctant to start, do not press the
starter button for longer than 20 seconds, but try
again after a few seconds.
3.
The battery clamps must be cleaned regularly
and covered with a layer of vaseline or petroleum
jelly to prevent corrosion.
4.
Make sure the vents in the filler plugs are kept
clean.
5.
The batteries must never be disconnected while
the engine is running, or permanent damage to
the alternator and the electronic systems may
result.
6.
Never switch off the ignition while the engine is
running on full speed. This is to prevent running
out of the turbocharger propeller without
lubricant.
7.
To safeguard battery life, switch off any lighting,
the heating/Ventilation/AC and the mirror heating
before starting the engine.
8.
Under normal conditions, do not add sulphuric
acid to the batteries.
9.
The batteries should be stored in a fully charged
condition.
10. The batteries should be charged every 8 to 10
weeks with 5 to 6 amperes current for a period of
24 hours.
CAUTION
Do not charge a frozen battery as it may explode!
4-114
SECTION 4 - LUBRICATION AND MAINTENANCE
ALTERNATOR
NOTE: The engine is equipped with an alternator.
Certain precautions must be observed to avoid
serious damage to the alternator, batteries and
wiring.
When carrying out any maintenance work, the
following instructions must be observed:
1. Disconnect the batteries using the battery switch
if any electric welding work is to be carried out on
the combine.
Secure the negative (-) terminal of the welding
apparatus as close as possible to the part to be
welded.
2. The positive (+) lead of the batteries is live at all
times. To prevent damage, always disconnect the
battery earth lead (-) first.
3. Ensure the batteries are connected properly, i.e.
negative (-) lead to the negative (-) terminal and
positive (+) lead to the positive (+) terminal.
4. Always connect a booster battery in parallel, i.e.
negative (-) to negative (-), and positive (+) to
positive (+).
5. Disconnect the batteries using the battery switch
before connecting a battery charger.
Ensure the battery charger is properly
connected.
6. Never run the engine if the wiring between the
alternator and the battery has been
disconnected.

CAB/CLIMATE CONTROL
Cab air filter
The cab air filter is located near the cab door on the
left hand side.
Clean the cab air filter regularly and, in extremely
dusty conditions, daily.
Wear a suitable dust mask!
To remove the cab air filter, proceed as follows:
1. Pull yellow slider 1.
2. Cover 2 can be removed with a smooth twist to
the left, and than pulling it towards you.
217
3. Remove filter element 3.
4. Clean with compressed air blown from the inside
towards the outside.
It is advisable to replace the filter elements every
year.
Installation:
1. Install filter element 3 in the housing.
218
4-116
SECTION 4 - LUBRICATION AND MAINTENANCE
2. Install the cover. The dust outlet on the cover
should be pointed to the floor.
3. To close the housing turn cover 2 to the right till
it locks.
4. Lock the cover with yellow slider 1.
CAUTION
Dust protection: The air filter in the cab does not
protect against all substances
(e.g. chemical
residues on crops). Absolute protection against
specific products can only be obtained when the
nature of these products is known and adequate
measures are purposely designed to counter the
hazard created by these substances. Even the use of
219
carbon filters cannot ensure complete protection. It
goes without saying that correct filter maintenance
and keeping doors and windows closed is essential.
Air conditioning
For a correct use of the air-conditioning system:
• Keep the cab doors closed.
• Use the air conditioning as much as possible.
• Control the desired temperature with the
air-conditioning button (thermostat).
Pay regular attention to the following:
• The status of the sight glass and the moisture
indicator, on the filter drier, located on the engine
fan area.
• The cleanness of the condenser, located on the
engine rotary screen door.
• The cleanness of the cab fresh air filter located
under the left front corner of the grain tank.
• The cleanness of the cab air recirculation filter,
located on the right-hand rear cab wall beside the
operator seat.
• The condensation water flowing from the drain
tubes, check valves in humid conditions.
