• GENERAL INSTRUCTIONS
• IMPORTANT NOTICE
• 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.
• 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 that require the
  engine running). Once the specific opera- tion
  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
• smear 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

• Do not carry out repair operations with someone
  sitting in the drivers seat, unless the person
  is a trained technician who is assisting with
  the op- eration in question.
• Do not operate the vehicle or use any of the im-
  plements from different positions, other than the
  drivers seat.
• Do not carry out operations on the vehicle with
  the engine running, unless 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.
• 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.

TO PREVENT ACCIDENTS 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.
GENERAL GUIDELINES
- Carefully follow specified repair and mainte-
nance procedures.
- Do not wear rings, wristwatches, jewelry,
unbut- toned 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 cloth- ing, e.g non- slip
footwear, gloves, safety goggles, helmets, etc.

SECTION 00 - GENERAL - CHAPTER 1 5

• The fuel nozzle should always be in contact with
  the filling aperture maintain this contact until
  the fuel stops flowing into the tank to avoid
  possible sparks due to static electricity build-
  up.
• Only use specified towing points for towing the
  vehicle. 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 vehicle 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 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,
  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.

  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 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 its attachments,
  check, adjust and block the operators seat. Also
• check that there are no persons within the
  vehicle or implement range of action.
• Empty pockets of all objects that may fall unob-
  served into the vehicle parts.
• In the presence of protruding metal parts, use
  protective goggles or goggles with side guards,
  helmets, special footwear and gloves.

DESCRIPTION AND OPERATION
EXHAUST GAS RECIRCULATION SYSTEM (EGR) On the
TIER 3 version, the exhaust cam profile has been
modified to permit partial opening of the related
valve during the inlet phase (exhaust gas
recircula- tion EGR) with the consequent re-
introduction of some of the exhaust gases into
the engine cylinders. The exhaust gases can be
partially redirected into the cylinders in order
to reduce the maximum combustion temperature
values which are responsi- ble for the
production of nitrogen oxide (NOx). The exhaust
gas recirculation system (EGR), reducing the
temperature of combustion by decreasing the
concentration of oxygen in the combustion
chamber, is therefore an effective system to
control emissions of NOx.
The internal EGR system is not provided with any
electronically controlled elements the system is
always on. Its configuration needs no additional
elements such as control valves, pipes or heat
exchangers. The exhaust cam (B) in addition to
the main lobe has another lobe (see sect. A- A,
fig. 5) with respect to the configuration
without EGR. The additional lobe, during the
inlet phase of the cylinder under examination,
permits briefly opening the exhaust valve
generating recirculation due to the exhaust
gases returning caused by the lower pressure
created in the inlet phase inside the cylinder.
