SECTION 00 -- GENERAL -- CHAPTER 1 1
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 operations, disconnect and isolate the battery negative lead, unless other-
wise requested for specific operations (e.g.: operations that require the engine running). Once the specific oper-
ation has been completed, disconnect the lead in order to complete the operation.
SHIMMING
For each adjustment operation, select adjusting shims and measure individually using a micrometer, then add
up the recorder values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated
value indicated for each on 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, LOC-
TITE 5205, SUPERBOND 559 MASCHERPA or BETABLOCK A272M GURIT ESSEX.
Before applying the sealing compound, prepare the surfaces as follows:
-- remove any incrustations 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
When installing bearings it is advised to:
-- heat the bearings to 80 to 90 °C (176 to 194 °F) before fitting on the shafts;
-- allow the bearings to cool before installing them from the outside.
SPRING PINS
When fitting split socket spring 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.

2SECTION 00 -- GENERAL -- CHAPTER 1
SPARE PARTS
Only use original NEW HOLLAND spare parts bearing the logo shown below.
1
Only original spare parts guarantee the same quality, duration and safety as they are the same parts that are
assembled during production.
Only original NEW HOLLAND 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.
TOOLS
The tools that NEW HOLLAND propose and illustrate in this manual are:
-- specifically researched and designed for use with NEW HOLLAND tractors;
-- essential for reliable repair operations;
-- accurately built and rigorously tested so as to offer efficient and long--lasting operation.
By using these tools, Repair Personnel will benefit from:
-- operating in optimal technical conditions;
-- obtaining the best results;
-- saving time and effort;
-- working in safe conditions.
NOTE
Wear limit values indicated for certain parts are recommended, but not binding. The terms ”front”, ”rear”, ”right--
hand” and ”left--hand” (when referred to different parts) are intended as seen from the driving position with the
tractor in the normal direction of movement.
MOVING THE TRACTOR WITH THE BATTERY REMOVED
External power supply cables should only be connected to the respective positive and negative cable terminals,
using efficient clamps that guarantee adequate and secure contact.
Disconnect all services (lights, windshield wipers, etc.) before starting the tractor.
If the tractor electrical system requires checking, carry out operations with the power supply connected. Once
checking is completed, disconnect all services and switch off the power supply before disconnecting the cables.

SAFETY REGULATIONS
WARNING AND DANGER 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:
WARNING -- Warnings concerning unsuitable repair
operations that may jeopardise the safety of Repair
personnel.
DANGER -- Specific warnings concerning potential
hazards for operator safety or for other persons di-
rectly 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 conse-
quently acting with the necessary caution and care.
Accidents may occur with all types of machine, re-
gardless of how well the machine in question was de-
signed 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.
2
-- 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.
-- Do not operate the machine or use any of the im-
plements from different positions, other than the
driver’s seat.
-- Do not carry out operations on the machine with
the engine running, unless specifically indicated.
-- Stop the engine and check that the hydraulic cir-
cuits are pressure--free before removing caps,

carried out using extreme care and attention.
-- Service steps and platforms used in the work-
shop or elsewhere should be built according to
standard accident prevention regulations.
-- Disconnect the batteries and label all controls to
indicate that the tractor is being serviced. Any
parts that are to be raises must be locked in posi-
tion.
-- Do not check or fill fuel tanks, accumulator bat-
teries, nor use starting liquid when smoking or
near naked flames, as these fluids are inflam-
mable.
-- 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 fill-
ing operations are completed in order to avoid
possible sparks caused by the accumulation of
static electricity.

4SECTION 00 -- GENERAL -- CHAPTER 1
-- 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 tractors that cannot be driven using a
trailer or a low--loading platform trolley, if avail-
able.
-- When loading or unloading the tractor 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 gasoline or diesel oil into open, wide
or low containers.
-- Never use gasoline, diesel oil or other inflam-
mable liquids as cleaning agents. Use non--in-
flammable, non toxic commercially available sol-
vents.
-- Wear safety goggles with side guards when
cleaning parts with compressed air.
-- Limit the air pressure to a maximum of 2.1 bar (31
PSI), 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 tractor. 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
tractor on a flat surface and lock in position. If
working on a slope, lock the tractor 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 by-
standers.
-- 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
store rags in a closed metal container.
Before starting the tractor or implements, make
sure that the driver’s seat is locked in position.
Also check that there are no persons within the
tractor or implement range of action.
-- Empty pockets of all objects that may fall unob-
served into the tractor parts.
-- 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:
tinted safety goggles, helmets, special overalls,
gloves and footwear. All persons present in the
area where welding is taking place must wear
tinted 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. Wear suitable
safety clothing -- safety goggles, gloves and
shoes.
