any way contrary to the intended use or if the machine is not properly driven or maintained then the Company

will not accept any liability whatsoever for any damage or injury (whether direct or consequential).

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

up to Serial No. 51200727.

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.

AXLES AND STEERING

AXLES & STEERING 1.1

Axles

Description

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.

wheels straight ahead, in line with the chassis. Fit

chocks to the front and rear of the rear wheels.

2. Raise the boom and fit the boom safety stop.

3. Stop the engine and apply the parking brake.

4. Refer to page 1.53 and dump hydraulic pressure

from the brake systems, then disconnect the

battery.

5. Disconnect the drive shaft from the axle flange

and support clear of axle.

AXLES & STEERING1.4

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.
