The method of operation and maintenance specified in this handbook should be strictly adhered to.
For your parts requirements, it is essential that only genuine CLAAS parts are fitted.Any resultant damage
from non-genuine parts will invalidate your machine warranty.
CLAAS operates a policy of continuous improvement to its products and reserve the right to change specifica-
tions and equipment without notice. Therefore some information within this handbook may differ from your
machine.
This manual is designed to service machines:
from Serial No. 51200011

INTRODUCTION
General
The contents of this Repair Manual, although correct at the time of publication, may be subject to alteration by
the manufacturer without notice.
This manual assumes that maintenance personnel have a sound knowledge of workshop practices and
safety procedures associated with the repairs of this type of machine. This manual is designed to assist with
the more specialised information required for removal and strip-down of major components.
It is recommended that the relevant part of this Repair Manual is studied carefully before proceeding with any
maintenance.
Machine identification
To make sure that the correct parts are obtained, always quote the machine Serial Number when ordering
parts.
Health and Safety
To prevent injury to personnel and damage to equipment and machinery, care must be taken to operate in a
safe manner. Read the Safety Warnings that follow and always work in a safe manner and obey the relevant
Warnings.
Throughout this manual and on the machine there are safety notes. Each note starts with a single word.The
meaning of these single words is as follows:
Identifies a hazard exists. If proper precautions are not taken, it is highly probable that the
operator (or others) could be killed or seriously injured.
Identifies a reminder of safety practices. Failure to observe these safety practices could result
in injury to the operator (or others) or damage to the machine.
In general these notes are used to indicate that the procedures being described in the manual must be
followed to avoid serious injury or death to yourself or others. The notes are also used to protect the machine
from unsafe maintenance practices.
SAFETY WARNINGS
Always wear correct fitting protective clothing. Loose or baggy clothing can be extremely
dangerous when operating or maintaining a machine.
Where possible, only work on or close to engines or machinery when they are stopped. If this
is not practical, remember to keep tools, test equipment and all parts of your body well away
from moving parts.
Avoid contact with exhaust pipes and exhaust manifolds when the engine is running; these
can be very hot.
Many liquids used on this machine are harmful if taken internally or splashed into the eyes. In
the event of accidentally swallowing oil, diesel fuel, anti-freeze, battery acid etc., DO NOT
induce vomiting, but OBTAIN QUALIFIED MEDICALASSISTANCE IMMEDIATELY.
Always obtain advice before mixing oils; some are incompatible.
Never run an engine in an enclosed space unless an exhaust extraction system is used.
Always disconnect battery cables before working on the electrical system to prevent injury
caused by electric shock.
When it is necessary to work on the electrical system with power on, for fault diagnosis,
always have a safety man in attendance
Any dust found on the machine or produced during work on the machine should be removed
by extraction, not by blowing. Dust waste should be dampened, placed in a sealed container
and marked for safe disposal.
Always dump pressure from the hydraulic system before carrying out any maintenance or
adjustment (refer to Hydraulic Repair Manual).
Never leave the machine unattended with pressure in the system.
Fine jets of hydraulic fluid at high pressure can penetrate the skin. Do not use your fingers to
check for hydraulic fluid leaks. Do not put your face close to suspected leaks. If hydraulic fluid
penetrates your skin OBTAIN QUALIFIED MEDICALASSISTANCE IMMEDIATELY.
Never allow unqualified personnel to attempt to remove or replace any part of the machine.
Always use the correct lifting equipment to remove large or heavy components.
Never attempt to lift or hold up the machine using the lash-down points.

The front and rear axles are both double reduction by
bevelset andplanetaryhubreduction gears,both have
limited slip differentials. The front axle incorporates a
parking brake.
Steering is available to both axles, depending on the
steering mode selected. The axle hubs are steered
by the operation of a double acting hydraulic cylinder
attached to the axle.

NOTES:
(1) Sealing Compound. Ensure both surfaces
to be sealed are clean, dry and free from grease.
(2) O-ring seals. Lubricate seals before fitting
to prevent twisting when inserting the shaft
(3) Bearings. It is recommended (but not
mandatory) that bearings are heated to 80°C -
90°C before fitting to shaft, or cooling with dry ice
before inserting them into an outer housing.
(4) Shims. Measure shims before use, do not
rely on measurement marked on shim.
(5) Torque loading. Torque load all
components to the recommended figure.
(6) Oil seals. To assist with the correct
installation of oil seals carry out the following:
- Ensure the shaft is clean and not damaged
- Assemble with lip side towards the oil side
- Lubricate seal with oil and fill ¾ of seal
cavity with grease
- Use special tools to install seals, where
available. Do not hammer directly on the
seal
- Do not damage seals while assembling the
shaft.
(7) Special tools. Use the special tools to
dismantle and assemble the axle.
