SECTION 00 -- GENERAL -- CHAPTER 1 1
84419878A -- 06 -- 2011
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
responsible 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
otherwise requested for specific operations (e.g.: operations requiring the engine to be running), after which it
is necessary 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
direction 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;
-- 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
twisting, which would jeopardise sealing efficiency.
SEALING COMPOUNDS
Apply one of the following sealing compounds on the mating surfaces marked with an X: LOCTITE 518 or
LOCTITE 5205 or SUPERBOND 559 or BETALOK A272M.
Before applying the sealing compound, prepare the surfaces as follows:
-- remove any incrustations using a wire brush;
-- thoroughly degrease the surfaces using one of the following cleaning agent: trichlorethylene, petrol or a water
and soda solution.
BEARINGS
When installing bearings it is advised to:
-- heat the bearings to 80 ÷90 0C before fitting on the shafts;
-- allow the bearings to cool before installing them from the outside.

84419878A -- 06 -- 2011
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 on the “Spare Parts Catalogue”, which is the base for
order processing.
NOTES FOR EQUIPMENT
The tools that CASE IH offer and illustrate in this manual are:
-- specifically researched and designed for use with CASE IH vehicles;
-- necessary to make a reliable repair;
-- accurately built and strictly tested to offer efficient and long--lasting working means.
By using these tools, repair personnel will benefit from:
-- operating in optimal technical conditions;
-- obtaining the best results;
-- save time and effort;
-- working in safe conditions.
IMPORTANT NOTES
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 vehicle.
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.
