WARNING
All maintenance and repair work described in
this manual must be performed exclusively by
CASE IH service technicians in strict accordance
with the instructions given and using any
specific tools necessary.
WARNING
Anyone who performs the operations described
herein without strictly following the instructions
is personally responsible for resulting injury or
damage to property.
WARNING
The Manufacturer and all organizations belong-
ing to the Manufacturer’s distribution network,
including but not restricted to national, regional
or local distributors, will accept no responsibility
for personal injury or damage to property caused
by abnormal function of parts and/or compo-
nents not approved by the Manufacturer,
including those used for maintenance and/or
repair of the product manufactured or marketed

GENERAL INSTRUCTIONS
IMPORTANT NOTICE
All maintenance and repair operations described in
this manual should be carried out exclusively by the
authorized 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 direc-
tives will be directly responsible for resulting
consequences.
SHIMMING
At each adjustment, select adjusting shims, measure
them individually using a micrometer and then sum
up recorded values. Do not rely on measuring the
whole shimming set, which may be incorrect, or on
the rated value indicated for 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
(oil rather than grease) and fill the gap between
the sealing lip and the dust lip of double lip seals
with grease;
• Insert the seal into its seat and press it down
using a flat punch. Do not tap the seal with a
hammer or a drift;
• Take care to insert the seal perpendicular 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.
O RINGS
Lubricate the O rings before inserting them into their
seats. This will prevent the O rings from roll over and
twisting during mounting, which will jeopardize
sealing.
SEALERS
Apply silicone/gasket eliminator over the mating
surfaces marked with an X.
Before applying the sealer, prepare the surface as
follows:
• remove possible scales using a metal brush;
• thoroughly degrease the surfaces using one of
the following cleaning agents: trichlorethylene,
diesel fuel or a water and soda solution.
BEARINGS
It is advisable to heat the bearings to 80° to 90°C
(176° to 194°F) before mounting them on their shafts
and cool them down before inserting them into their
seats with external tapping.
SPRING PINS
When mounting split socket spring pins, ensure that
the pin notch is oriented in the direction of the effort
to stress the pin.
Spiral spring pins should not be oriented during
installation.

HEALTH AND SAFETY PRECAUTIONS
Many of the procedures associated with vehicle
maintenance and repair involve physical hazards or
other risks to health. This section lists, alphabeti-
cally, some of these hazardous operations and the
materials and equipment associated with them. The
precautions necessary to avoid these hazards are
identified.
The list is not exhaustive and all operations and
procedures and the handling of materials, should be
carried out with health and safety in mind.

SECTION 00 -
- GENERAL -
- CHAPTER 1
6
ACIDS AND ALKALIS -- see Battery acids, e.g.
caustic soda, sulfuric acid.
Used in batteries and cleaning materials.
Irritant to the skin, eyes, nose and throat. Causes
burns.
Avoid splashes to the skin, eyes and clothing. Wear
suitable protective gloves and goggles. Can destroy
ordinary protective clothing. Do not breathe mists.
Ensure access to water and soap is readily available
for splashing accidents.
ADHESIVES AND SEALERS -- see Fire
Highly Flammable and combustible.
Generally should be stored in “No Smoking” areas;
cleanliness and tidiness in use should be observed,
e.g. disposable paper covering benches; should be
dispensed from applicators where possible; contain-
ers, including secondary containers, should be
labelled.
Solvent based Adhesives/Sealers -- See Solvents.
Follow manufacturers instructions.
Water based Adhesives/Sealers
Those based on polymer emulsions and rubber
lattices may contain small amounts of volatile toxic
and harmful chemicals. Skin and eye contact should
be avoided and adequate ventilation provided during
use.
Follow manufacturers instructions.
Resin based Adhesives/Sealers -- e.g. epoxide
and formaldehyde resin based.
Mixing should only be carried out in well ventilated
areas as harmful or toxic volatile chemicals may be
released.
Skin contact with uncured resins and hardeners can
result in irritation; dermatitis and absorption of toxic
or harmful chemicals through the skin. Splashes can
damage the eyes.
Provide adequate ventilation and avoid skin and eye
contact. Follow manufacturers instructions.
Anaerobic, Cyanoacrylate and other Acrylic
Adhesives
Many are irritant, sensitizing or harmful to the skin.
Some are eye irritants.
Skin and eye contact should be avoided and the
manufacturers instructions followed.
Cyanoacrylate adhesives (super--glues) must not
contact the skin or eyes. If skin or eye tissue is
bonded cover with a clean moist pad and get medical
attention. do not attempt to pull tissue apart. Use in
well ventilated areas as vapors can cause irritation of
the nose and eyes.
For two--pack systems see Resin based adhesives/
sealers.
Isocyanate (Polyurethane) Adhesives/
Sealers -- see Resin based Adhesives.
Individuals suffering from asthma or respiratory
allergies should not work with or near these materials
as sensitivity reactions can occur.
Any spraying should preferably be carried out in
exhaust ventilated booths removing vapors and
spray droplets from the breathing zone. Individuals
working with spray applications should wear
supplied air respirators.
ANTIFREEZE -- see Fire, Solvents e.g.
Isopropanol, Ethylene Glycol, Methanol.
Highly Flammable and Combustible.
Used in vehicle coolant systems, brake air pressure
systems, screenwash solutions.
Vapors given off from coolant antifreeze (glycol) arise
only when heated.
Antifreeze may be absorbed through the skin in toxic
or harmful quantities. Antifreeze if swallowed is fatal
and medical attention must be found immediately.

CHEMICAL MATERIALS -
- GENERAL -- see
Legal Aspects.
Chemical materials such as solvents, sealers,
adhesives, paints, resin foams, battery acids,
antifreeze, brake fluids, oils and grease should
always be used with caution and stored and handled
with care. They may be toxic, harmful, corrosive,
irritant or highly flammable and give rise to
hazardous fumes and dusts.
The effects of excessive exposure to chemicals may
be immediate or delayed; briefly experienced or
permanent; cumulative; superficial; life threatening;
or may reduce life--expectancy.
DO’S
Do remove chemical materials from the skin and
clothing as soon as practicable after soiling. Change
heavily soiled clothing and have it cleaned.
Do carefully read and observe hazard and
precaution warnings given on material containers
(labels) and in any accompanying leaflets, poster or
other instructions. Material health and safety data
sheets can be obtained from Manufacturers.
Do organize work practices and protective clothing to
avoid soiling of the skin and eyes; breathing
vapors/aerosols/dusts/fumes; inadequate container
labelling; fire and explosion hazards.
Do wash before job breaks; before eating, smoking,
drinking or using toilet facilities when handling
chemical materials.
Do keep work areas clean, uncluttered and free of
spills.
Do store according to national and local regulations.
