GENERAL INSTRUCTIONS
IMPORTANT NOTICE
All maintenance and repair operations described in this manual should be carried out exclusively by the NEW
HOLLAND authorised workshops. All instructions detailed should be carefully observed and special equipment
indicated should be used if necessary.
Everyone who carries out service operations described without carefully observing these prescriptions will be
directly responsible of deriving damages.
SHIMS
At each adjustment, select adjusting shims, measure them individually using a micrometer and then sum up
recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value
indicated on each shim.
ROTATING SHAFT SEALS
To correctly install rotating shaft seals, observe the following instructions:
- Let the seal soak into the same oil as it will seal for at least half an hour before mounting
- Thoroughly clean the shaft and ensure that the shaft working surface is not damaged.
- Place the sealing lip towards the fluid. In case of a hydrodynamic lip, consider the shaft rotation direction and
orient grooves in order that they deviate the fluid towards the inner side of the seal.
- coat the sealing lip with a thin layer of lubricant (use oil rather than grease) and fill the gap between the sealing
lip and the dust lip on double lip seals with grease;
- Insert the seal into its seat and press it down using a flat punch. Do no tap the seal with a hammer or a drift;
- Take care to insert the seal perpendicularly to its seat while you are pressing it. Once the seal is settled, ensure
that it contacts the thrust element if required;
To prevent damaging the sealing lip against the shaft, place a suitable protection during installation.
ORINGS
Lubricate the O rings before inserting them into their seats. This will prevent the O rings from rolling over and
twine during mounting which will jeopardise sealing.
SEALANTS
Apply one of the following sealers: RTV SILMATE, RHODORSIL CAF 1, or LOCTITE PLASTIC GASKET over
thematingsurfacesmarkedwithanX.
Before applying the sealer, prepare the surface as follows:
remove possible scales using a metal brush;
- thoroughly de-grease the surfaces using one of the following cleaning agents: trichlorethylene, petrol or a
water and soda solution.
BEARINGS
It is advisable to heat the bearings to 80 to 90 C before mounting them on their shafts and cool them down before
inserting them into their seats with external tapping.
ROLL PINS
When fitting straight roll pins, ensure that the pin notch is oriented in the direction of the effort to stress the pin.
Coil roll pins can be installed in any position.

SAFETY RULES
PAY ATTENTION TO THIS SYMBOL
This warning symbol points out important messages involving personal safety.
Carefully read the safety rules contained herein and follow advised precautions to
avoid potential hazards and safeguard your safety and personal integrity.
In this manual you will find this symbol together with the following key-words:
WARNING -it gives warning about improper repair operations and potential
consequences affecting the service technician’s personal safety.
DANGER -it givesspecific warningaboutpotential dangersfor personalsafety ofthe
operator or other persons directly or indirectly involved in the operation.
TO PREVENT ACCIDENTS
Most accidents and personal injuries taking place in
workshops are due from non-observance of some
simple and essential prudential rule and safety
precautions. For this reason, IN MOST CASES
THEY CAN BE AVOIDED. It suffices to foresee
possible causes and act consequently with
necessary caution and care.
The possibility that an accident might occur with any
type of machines should not be disregarded, no
matter how well the machine in question was
designed and built.
A wise and careful service technician is the best
precautions against accidents.
Careful observance of this only basic precaution
would be enough to avoid many severe accidents.
DANGERNever carry out any cleaning, lubrication or
maintenance operations when the engine is running.
SAFETY RULES
GENERAL
(Carefully follow specified repair and
maintenance procedures.
(Do not wear rings, wrist watches, jewelry,
unbuttoned or loose articles of clothing such as:
ties, torn clothing, scarves, open jackets or shirts
with open zips which may remain entangled in
moving parts. We advise to use approved safety
clothing such as anti-slipping footwear, gloves,
safety goggles, helmets, etc.
(Never carry out any repair on the machine if
someone is sitting on the operator’s seat, except
if they are certified operators to assist in the
operation to be carried out.
(Never operate the machine or use attachments
from a place other than sitting at the operator’s
seat.
(Never carry out any operation on the machine
when the engine is running, except when
specifically indicated.
(Stop the engine and ensure that all pressure is
relieved from hydraulic circuits before removing
caps, covers, valves, etc.
(All repair and maintenance operations must be
carried out using extreme care and attention.
(Service steps and platforms used in a workshop
or in the field should be built in compliance with
the safety rules in force.
(Disconnect the batteries and label all controls to
indicate that the vehicle is being serviced. Block
the machine and all equipment which should be
raised.
(Never check or fill fuel tanks or batteries, nor use
starting liquid if you are smoking or near open
flames as such fluids are flammable.
(Brakes are inoperative when they are manually
released for maintenance purposes. In such
cases, the machine should be kept constantly
under control using blocks or similar devices.
(The fuel filling gun should always remain in
contact with the filler neck. Maintain this contact
until the fuel stops flowing into the tank to avoid
possible sparks due to static electricity build-up.

SECTION 00 - GENERAL - CHAPTER 1
4
47840677-03-2015
(Use exclusively specified towing points for
towing the tractor. Connect parts carefully.
Ensure that foreseen pins and/or locks are
steadily fixed before applying traction. Do not
stop near towing bars, cables or chains working
under load.
(To transfer a failed tractor, use a trailer or a low
loading platform trolley if available.
(To load and unload the machine from the
transportation means, select a flat area providing
a firm support to the trailer or truck wheels. Firmly
tie the machine to the truck or trailer platform and
block wheels as required by the forwarder.
(For electrical heaters, battery-chargers and
similar equipment use exclusive auxiliary power
supplies with a efficient ground to avoid electrical
shock hazard.
(Always use lifting equipment of appropriate
capacity to lift or move heavy components.
(Pay special attention to bystanders.
(Never pour gasoline or diesel oil into open, wide
and low containers.
(Never use petrol, diesel oil or other inflammable
liquids as cleaning agents. Use non-flammable
non-toxic proprietary solvents.
(Wear safety glasses with side guards when
cleaning parts using compressed air.
(Do not exceed a pressure of 2.1 bar, in
accordance with local regulations.
(Do not run the engine in a closed building without
proper ventilation.
(Do not smoke, use naked flames, or cause
sparks in the area when fuel filling or handling
highly inflammable liquids.
(Do not use flames as light sources when working
on a machine or checking for leaks.
(Move with caution when working under a tractor,
and also on or near a tractor. Wear proper safety
accessories: helmets, goggles and special
footwear.
(During checks which should be carried out with
the engine running, ask an assistant to seat at the
operator’s seat and keep the service technician
under visual control at any moment.
(In case of operations outside the workshop, drive
the tractor to a flat area and block it. If working on
an incline cannot be avoided, first block the
tractor carefully. Move it to a flat area as soon as
possible with a certain extent of safety.
(Ruined or plied cables and chains are unreliable.
Do not use them for lifting or trailing. Always
handle them wearing gloves of proper thickness.
(Chains should always be safely fastened.
Ensure that fastening device is strong enough to
hold the load foreseen. No persons should stop
near the fastening point, trailing chains or cables.
(The working area should be always kept CLEAN
and DRY. Immediately clean any spillage of
wateroroil.
(Do not pile up grease or oil soaked rags, as they
constitute a great fire hazard. Always place them
into a metal container.
Before starting the tractor or its attachments,
check, adjust and block the operator’s seat. Also
ensure that there are no persons within the
tractor or attachment operating range.
(Do not keep in your pockets any object which
might fall unobserved into the tractor’s inner
compartments.
(Whenever there is the possibility of being
reached by ejected metal parts or similar, use
protection eye mask or goggles with side guards,
helmets, special footwear and heavy gloves.
(Wear suitable protection such as tinted eye
protection, helmets, special clothing, gloves and
footwear whenever it is necessary to carry out
welding procedures. All persons standing in the
vicinity of the welding process should wear tinted
eye protection. NEVER LOOK AT THE
WELDING ARC IF YOUR EYES ARE NOT
SUITABLY PROTECTED.
(Metal cables with the use get frayed. Always
wear adequate protections (heavy gloves, eye
protection, etc.)
(Handle all parts with the greatest caution. Keep
your hands and fingers far from gaps, moving
gears and similar. Always use approved
protective equipment, such as eye protection,
heavy gloves and protective footwear.

SECTION 00 - GENERAL - CHAPTER 1 5
47840677-03-2015
STARTUP
(Never run the engine in confined spaces that are
not equipped with adequate ventilation for
exhaust gas extraction.
(Never place the head, body, limbs, feet, hands or
fingers near fans or rotating belts.
ENGINE
(Always loosen the radiator cap very slowly before
removing it to allow pressure in the system to
dissipate. Coolant should be topped up only when
the engine is stopped or idle if hot.
(Do not fill up fuel tank when the engine is running,
mainly if it is hot, to avoid ignition of fires in case
of fuel spilling.
(Never check or adjust fan belt tension when the
engine is running.
Never adjust the fuel injection pump when the
tractor is moving.
(Never lubricate the tractor when the engine is
running.
ELECTRICAL SYSTEMS
(If it is necessary to use auxiliary batteries, cables
must be connected at both sides as follows: (+)
with (+) and (-) with (-). Avoid short-circuiting the
terminals. GAS RELEASED FROM BATTERIES
IS HIGHLY FLAMMABLE. During charging, leave
the battery compartment uncovered to improve
ventilation. Avoid checking the battery charge by
means of ”jumpers” made by placing metallic
objects across the terminals. Avoid sparks or
flames near the battery zone. Do not smoke to
prevent explosion hazards.
(Before servicing operations, check for fuel or
current leaks. Remove these leaks before going
on with the work.
(Do not charge batteries in confined spaces.
Ensure that ventilation is appropriate to prevent
accidental explosion hazard due to build-up of
gases released during charging.
(Always disconnect the batteries before
performing any type of service on the electrical
system.
HYDRAULIC SYSTEMS
(Some fluid slowly coming out from a very small
port can be almost invisible and be strong enough
to penetrate the skin. Therefore, NEVER USE
HANDS TO CHECK FOR LEAKS but use a piece
of cardboard or wood for this purpose. If any fluid
is injected into the skin, seek medical aid
immediately. Lack of immediate medical
attention, serious infections or dermatosis may
result.
(Always take system pressure readings using the
appropriate gauges.
WHEELS AND TYRES
(Check that the tyres are correctly inflated at the
pressure specified by the manufacturer.
Periodically check possible damages to the rims
and tyres.
(Keep off and stay at the tyre side when correcting
the inflation pressure.
(Check the pressure only when the tractor is
unloaded and tyres are cold to avoid wrong
readings due to over-pressure. Do not reuse parts
of recovered wheels as improper welding,
brazing or heating may weaken the wheel and
make it fail.
(Never cut, nor weld a rim with the inflated tyre
assembled.
(To remove the wheels, block both front and rear
tractor wheels. Raise the tractor and install safe
and stable supports under the tractor in
accordance with regulations in force.
(Deflate the tyre before removing any object
caught into the tyre tread.
(Never inflate tires using flammable gases, as this
may result in explosions and injury to bystanders.
REMOVAL AND INSTALLATION
(Lift and handle all heavy components using lifting
equipment with adequate capacity. Ensure that
parts are supported by appropriate slings and
hooks. Use lifting eyes provided to this purpose.
Take care of the persons near the loads to be
lifted.
(Handle all parts with care. Do not place your
hands or fingers between two parts. Wear
approved protective clothing such as safety
goggles, gloves and footwear.
(Do not twine chains or metal cables. Always wear
safety gloves when handling cables or chains.
