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.

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,
covers, valves, etc.
-- All repair and maintenance operations must be
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.
4. 4 SECTION 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 areunreliable.
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.
5. SECTION 00 -
- GENERAL -
- CHAPTER 1 5
START UP
-- Never run the engine in confined spaces that are
not equipped with adequate ventilation for ex-
haust gas extraction.
-- Never place the head, body, limbs, feet, hands or
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
tractor is moving.
-- Never lubricate the tractor 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 RE-
LEASED FROM BATTERIES IS HIGHLY IN-
FLAMMABLE. During charging, leave the bat-
tery compartment uncovered to improve
ventilation. Never check the battery charge using
”jumpers” (metal objects placed on the ter-
minals). Avoid sparks or flames near the battery
zone. Do not smoke to prevent explosion haz-
ards.
-- Before servicing operations, check for fuel or
current leaks. Eliminate any eventual leaks be-
fore 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
invisible but, at the same time, be powerful
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 liquid penetrates skin tissue, call for medical
aid immediately. Failure to treat this condition
with correct medical procedure may result inseri-
ous infection or dermatosis.
-- In order to check the pressure in the system use
suitable instruments.
WHEELS AND TIRES
-- Make sure that the tires are correctly inflated at
the pressure specified by the manufacturer.
Periodically check the rims and tires for damage.
-- Stand away from (at the side of) the tire when
checking inflation pressure.
-- Only check pressure when the tractor is un-
loaded and the tires are cold, to avoid incorrect
readings as a result of over--pressure. Do not use
parts of recovered wheels as incorrect welding
brazing or heating may weaken and eventually
cause damage to the wheel.
-- Never cut or weld a rim mounted with an inflated
tire.
-- To remove the wheels, lock both the front and
rear tractor wheels. After having raised the trac-
tor, position supports underneath, according to
regulations in force.
-- Deflate the tire before removing any objects that
may be jammed in the tire tread.
-- Never inflate tires using inflammable gases, as
this may result in explosions and injury to by-
standers.
REMOVAL AND RE-
-FITTING
-- Lift and handle all heavy parts using suitable ho-
isting equipment. Make sure that parts are sus-
tained by appropriate hooks and slings. Use the
hoisting eyebolts for lifting operations. 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 shoes.
-- Avoid twisting chains or metal cables. Always
wear safety gloves when handling cables or
chains.

Op. 10 001 30 COMPRESSION TEST
In case of poor engine performance, in addition to
checking the fuel injection system (injection nozzles
and injection pump), also test the compression on
each cylinder.
DANGER
Do not use matches, lighters, blow torches or any
form of naked flame as a source of light when inspect-
ing the engine due to the presence of inflammable
fluids and vapour.
Compression ratio
The compression ratio is a measure of the quantity of
air drawn into the cylinder, and provides an indication
of the efficiency of the sealing elements in the cylinder
(piston rings and valves).
Uniform compression in all the cylinders ensures that
they all perform an equal amount of work, provided
that each cylinder is injected with the same quantity
of fuel at the right time.
Low compression not only reduces engine perfor-
mance, it also causes incomplete fuel combustion
due to the lack of available combustion air.
The engine therefore gives poor performance with
excessive fuel consumption and, consequently, ex-
haust smoke and restriction of the exhaust passages.
As the compression ratio also varies with the tem-
perature of the engine (cold engines produce lower
compression values than hot engines), the compres-
sion should only be tested when the engine is at nor-
mal operating temperature.
Compression should be tested using the compres-
sion test kit 291309, as follows:
1) Run the engine until it reaches normal operating
temperature.
2) Switch off the engine.
3) Disconnect the lead from the engine stop electro-
magnet on the injection pump in order to close the
valve and block the flow of fuel to the injectors.
4) Remove the injector from the cylinder to be tested.
5) Turn the engine over a few times with the starter
motor in order to expel any carbon residue.
6) Fit the dummy injector made from “Tools” on page
21, in place of the injector removed previously, inter-
posing the copper sealing washer.
7) Connect the compression test instrument 291309
and take readings while turning the engine over with
the starter motor.
On engines in perfect working order, with the sump oil
at approx. 40 oC (104 oF) at sea level (760 mm --
29.92 in. -- of mercury) and at an engine speed of 200
to rpm, the compression should be 25.5 to 27.5 bar
(369.9 to 398.9 psi).
8) Test the compression on the other cylinders, re-
peating steps 4--5--6--7, bearing in mind that:
The minimum permissible compression on a useden-
gine is 21.6 bar (313.3 psi).
The maximum permissible compression difference
between cylinders is 3 bar (43.5 psi).
Every 100 meters (109.36 yards) above sea level cor-
responds to a reduction in compression by approx.
1%.
CONSIDERATIONS:
Uniform compression
Although high compression is important, it is more im-
portant for smooth engine running that compression
is uniform in all cylinders.
Low compression readings
If extremely low pressure readings are obtained on
one cylinder it is advisable to repeat the test.
Before testing this time, pour approx. one spoonful of
engine oil into the cylinder through the injector bore.
Turn over the engine a few times to distribute the oil
evenly over the cylinder walls, and then repeat the
test.
If the second test readings are significantly higher,
the problem may be worn piston rings, out--of--round
or damaged pistons or liners.
If the second test readings are not higher, the prob-
lem will be the valves.
On the other hand, if the second test reading shows
only a slight improvement, the problem will be due to
both the valves and the rings.
