GENERAL INSTRUCTIONS
IMPORTANT NOTICE
All maintenance and repair work described in this manual must be performed exclusively by NEW HOLLAND
service technicians, in strict accordance with the instructions given and using any specific tools necessary.
Anyone performing the operations described herein without strictly following the instructions is personally re-
sponsible for any eventual injury or damage to property.
BATTERY
Before carrying out any kind of service operation disconnect and isolate the battery negative lead, unless other-
wise requested for specific operations (e.g.: operations requiring the engine to be running), after which it is neces-
sary to disconnect the above−mentioned lead to complete the work.
SHIMMING
For each adjustment operation, select adjusting shims and measure individually using a micrometer, then add
up the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated
value indicated for each shim.
ROTATING SHAFT SEALS
For correct rotating shaft seal installation, proceed as follows:
−before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes;
−thoroughly clean the shaft and check that the working surface on the shaft is not damaged;
−position the sealing lip facing the fluid; with hydrodynamic lips, take into consideration the shaft rotation direc-
tion and position the grooves so that they will 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 in its seat and press down using a flat punch; do not tap the seal with a hammer or mallet;
−whilst inserting the seal, check that the it is perpendicular to the seat; once settled, make sure that it makes
contact with the thrust element, if required;
−to prevent damaging the seal lip on the shaft, position a protective guard during installation operations.
“O−RING” SEALS
Lubricate the O−RING seals before inserting them in the seats, this will prevent them from overturning and twist-
ing, which would jeopardise sealing efficiency.
SEALING COMPOUNDS
Apply one of the following sealing compounds on the mating surfaces marked with an X: LOCTITE 518, LOCTITE
5205, SUPERBOND 559 MASCHERPA or BETABLOCK A272M GURIT ESSEX.
Before applying the sealing compound, prepare the surfaces as follows:
−remove any incrustations using a wire brush;
−thoroughly de−grease the surfaces using one of the following cleaning agents: trichlorethylene, petrol or a
water and soda solution.
BEARINGS
When installing bearings it is advised to:
−heat the bearings to 176 to 194 °F (80 to 90 °C) before fitting on the shafts;
−allow the bearings to cool before installing them from the outside.

2SECTION 00 −GENERAL GUIDELINES −CHAPTER 1
84131814A −06 −2008
SPRING PINS
When fitting split socket elastic pins, ensure that the pin notch is positioned in the direction of the force required
to stress the pin.
Spiral spring pins do not require special positioning.
SPARE PARTS
Use genuine parts only.
Only genuine spare parts guarantee the same quality, duration and safety as they are the same parts that are
assembled during production.
Only genuine parts can offer this guarantee.
When ordering spare parts, always provide the following information:
−tractor model (commercial name) and frame number;
−engine type and number;
−part number of the ordered part, which can be found in the “Microfiches” or the “Spare Parts Catalogue”, used
for order processing.

SAFETY REGULATIONS
PAY ATTENTION TO THIS SYMBOL
This warning symbol points out important messages
concerning your safety.
Carefully read the following safety regulations and
observe advised precautions in order to avoid poten-
tial hazards and safeguard your health and safety.
In this manual the symbol is accompanied by the fol-
lowing key−words:
CAUTION −Warnings concerning unsuitable repair
operations that may jeopardise the safety of Service
personnel.
DANGER −Specific warnings concerning potential
hazards for operator safety or for other persons dir-
ectly or indirectly involved.
ACCIDENT PREVENTION
Most accidents or injuries that occur in workshops
are the result of non−observance of simple and fun-
damental safety regulations. For this reason, IN
MOST CASES THESE ACCIDENTS CAN BE
AVOIDED by foreseeing possible causes and con-
sequently acting with the necessary caution and
care.
Accidents may occur with all types of vehicle, regard-
less of how well it was designed and built.
A careful and judicious service technician is the best
guarantee against accidents.
Precise observance of the most basic safety rule is
normally sufficient to avoid many serious accidents.
DANGER. Never carry out any cleaning, lubrication
or maintenance operations when the engine is run-
ning.
SAFETY REGULATIONS
GENERAL GUIDELINES
−Carefully follow specified repair and mainten-
ance procedures.
−Do not wear rings, wristwatches, jewellery, un-
buttoned or loose articles of clothing such as:
ties, torn clothing, scarves, open jackets or shirts
with open zips that may remain entangled in
moving parts. It is advised to wear approved
safety clothing, e.g.: non−slip footwear, gloves,
safety goggles, helmets, etc.
−Do not carry out repair operations with someone
sitting in the driver’s seat, unless the person is a
trained technician who is assisting with the oper-
ation in question.
1
−Do not operate the vehicle or use any of the im-
plements from different positions, other than the
driver’s seat.
−Do not carry out operations on the vehicle with
the engine running, unless specifically indicated.
−Stop the engine and check that the hydraulic cir-
cuits are pressure−free 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. Any
parts that are to be raised must be locked in posi-
tion.
−Do not check or fill fuel tanks, accumulator batter-
ies, nor use starting liquid when smoking or near
naked flames, as these fluids are inflammable.
−Brakes are inoperative when manually released
for repair or maintenance purposes. Use blocks
or similar devices to control the machine in these
conditions.
−The fuel nozzle should always be in contact with
the filling aperture. Maintain this position until
filling operations are completed in order to avoid
possible sparks caused by the accumulation of
static electricity.

4SECTION 00 −GENERAL GUIDELINES −CHAPTER 1
84131814A −06 −2008
−Only use specified towing points for towing the
tractor. Connect parts carefully. Make sure that
all pins and/or locks are secured in position be-
fore applying traction. Never remain near the
towing bars, cables or chains that are operating
under load.
−Transport vehicles that cannot be driven using a
trailer or a low−loading platform trolley, if avail-
able.
−When loading or unloading the vehicle from the
trailer (or other means of transport), select a flat
area capable of sustaining the trailer or truck
wheels. Firmly secure the tractor to the truck or
trailer and lock the wheels in the position used by
the carrier.
−Electric heaters, battery−chargers and similar
equipment must only be powered by auxiliary
power supplies with efficient ground insulation to
avoid electrical shock hazards.
−Always use suitable hoisting or lifting devices
when raising or moving heavy parts.
−Take extra care if bystanders are present.
−Never pour petrol or diesel oil into open, wide or
low containers.
−Never use petrol, diesel oil or other inflammable
liquids as cleaning agents. Use non−inflam-
mable, non toxic commercially available
solvents.
−Wear safety goggles with side guards when
cleaning parts with compressed air.
−Limit the air pressure to a maximum of 30.45 psi
(2.1 bar), according to local regulations.
−Do not run the engine in confined spaces without
suitable ventilation.
−Do not smoke, use naked flames, or cause
sparks in the area when fuel filling or handling
highly inflammable liquids.
−Never use naked flames for lighting when work-
ing on the machine or checking for leaks.
−All movements must be carried out carefully
when working under, on or near the vehicle.
Wear protective equipment: helmets, goggles
and special footwear.
−When carrying out checks with the engine run-
ning, request the assistance of an operator in the
driver’s seat. The operator must maintain visual
contact with the service technician at all times.
−If operating outside the workshop, position the
vehicle on a flat surface and lock in position. If
working on a slope, lock the vehicle in position.
Move to a flat area as soon as is safely possible.
−Damaged or bent chains or cables are unreliable.
Do not use them for lifting or towing. Always use
suitable protective gloves when handling chains
or cables.
−Chains should always be safely secured. Make
sure that the hitch−up point is capable of sustain-
ing the load in question. Keep the area near the
hitch−up point, chains or cables free of all
bystanders.
−Maintenance and repair operations must be car-
ried out in a CLEAN and DRY area. Eliminate any
water or oil spillage immediately.
−Do not create piles of oil or grease−soaked rags
as they represent a serious 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
check that there are no persons within the tractor
or implement range of action.
−Do not keep into your pockets any object which
might fall unobserved into the tractor’s inner
compartments.
−In the presence of protruding metal parts, use
protective goggles or goggles with side guards,
helmets, special footwear and gloves.
−When welding, use protective safety devices: tin-
ted safety goggles, helmets, special overalls,
gloves and footwear. All persons present in the
area where welding is taking place must wear tin-
ted goggles. NEVER LOOK DIRECTLY AT THE
WELDING ARC WITHOUT SUITABLE EYE
PROTECTION.
−Metal cables tend to fray with repeated use. Al-
ways use suitable protective devices (gloves,
goggles, etc.) when handling cables.
−Handle all parts carefully. Do not put your hands
or fingers between moving parts. Always wear
suitable safety clothing −safety goggles, gloves
and shoes.

SECTION 00 −GENERAL GUIDELINES −CHAPTER 1 5
84131814A −06 −2008
START UP
−Never run the engine in confined spaces that are
not equipped with adequate ventilation for ex-
haust gas extraction.
−Never bring your head, body, arms, legs, feet,
hands, fingers near fans or rotating belts.
ENGINE
−Always loosen the radiator cap slowly before re-
moving it to allow any remaining pressure in the
system to be discharged. Filling up with coolant
should only be carried out with the engine
stopped or idling (if hot).
−Never fill up with fuel when the engine is running,
especially if hot, in order to prevent the outbreak
of fire as a result of fuel spillage.
−Never check or adjust fan belt tension when the
engine is running.
Never adjust the fuel injection pump when the
vehicle is moving.
−Never lubricate the vehicle when the engine is
running.
ELECTRICAL SYSTEMS
−If it is necessary to use auxiliary batteries, re-
member that both ends of the cables must be
connected as follows: (+) with (+) and (−) with (−).
Avoid short−circuiting the terminals. GAS
RELEASED FROM BATTERIES IS HIGHLY
INFLAMMABLE. During charging, leave the bat-
tery compartment uncovered to improve ventila-
tion. Never check the battery charge using “jump-
ers” (metal objects placed on the terminals).
Avoid sparks or flames near the battery zone. Do
no smoke to prevent explosion hazards.
−Before servicing operations, check for fuel or cur-
rent leaks. Eliminate any eventual leaks before
proceeding with work.
−Never charge batteries in confined spaces. Make
sure that there is adequate ventilation in order to
prevent accidental explosion hazards as a result
of the accumulation of gases released during
charging operations.
−Always disconnect the batteries before perform-
ing any kind of servicing on the electrical system.
HYDRAULIC SYSTEMS
−A liquid leaking from a tiny hole may be almost in-
visible but, at the same time, be powerful enough
to penetrate the skin; Therefore, NEVER USE
HANDS TO CHECK FOR LEAKS. Use a piece of
cardboard or wood for this purpose. If any liquid
penetrates skin tissue, call for medical aid imme-
diately. Failure to treat this condition with correct
medical procedure may result in serious infection
or dermatosis.
−In order to check the pressure in the system use
suitable instruments.
WHEELS AND TYRES
−Check that the tyres are correctly inflated at the
pressure specified by the manufacturer.
Periodically check for possible damage to the
rims and tyres.
−Stand away from (at the side of) the tyre when
checking inflation pressure.
−Only check pressure when the tractor is un-
loaded and the tyres are cold, to avoid incorrect
readings as a result of over−pressure. Do not re-
use parts of recovered wheels as improper weld-
ing, brazing or heating may weaken the wheel
and make it fail.
−Never cut or weld a rim mounted with an inflated
tyre.
−To remove the wheels, lock both the front and
rear vehicle wheels. After having raised the
vehicle, position supports underneath, according
to regulations in force.
−Deflate the tyre before removing any object
caught in the tyre tread.
−Never inflate tyres using inflammable gases; as
this may result in explosions and injury to
bystanders.
REMOVAL AND INSTALLATION
−Lift and handle all heavy parts using suitable
hoisting equipment. Ensure that parts are sup-
ported by appropriate slings and hooks. Use lift-
ing eyes provided to this purpose. Extra care
should be taken if persons are present near the
load to be lifted.
−Handle all parts carefully. Do not put your hands
or fingers between parts. Wear suitable safety
clothing, safety goggles, gloves and footwear.
−Avoid twisting chains or metal cables. Always
wear safety gloves when handling cables or
chains.
