How To Use This Manual
Introduction
This Manual is designed to assist skilled technicians
in the efficient repair and maintenance of Discovery
vehicles.
Individuals who undertake their own repairs should
have some skill and training, and limit repairs to
components which could not affect the safety of the
vehicle or its passengers. Any repairs required to
safety critical items such as steering, brakes,
suspension or supplementary restraint system
should be carried out by a Land Rover Dealer.
Repairs to such items should NEVER be attempted
by untrained individuals.
General
To assist in the use of this Manual, it is divided into
sections and sub-sections. The section title is given
at the top of each page and the relevant sub-section
is given at the bottom.
There is a single contents section at the front of the
Manual, which is divided by section and sub-section.
Each section is numbered from page 1.
The individual items comprising repair operations are
to be followed in the sequence in which they appear.
Items numbers in the illustration are referred to in the
text.
Adjustment and Repair operations include reference
to Service tool numbers and the associated
illustration depicts the tool in use. Adjustment and
repair operations also include reference to wear
limits, relevant data, torque figures, and specialist
information and useful assembly details. Each
adjustment or repair operation is given its Service
Repair Operation number.
WARNINGS, CAUTIONS and NOTES have the
following meanings:
WARNING: Procedures which must be followed
precisely to avoid the possibility of injury.
CAUTION: Calls attention to procedures which
must be followed to avoid damage to
components.
NOTE: Gives helpful information.References
References to the LH or RH side given in this Manual
are made when viewing the vehicle from the rear.
With the engine and gearbox assembly removed, the
crankshaft pulley end of the engine is referred to as
the front.
Operations covered in this Manual do not include
reference to testing the vehicle after repair. It is
essential that work is inspected and tested after
completion and if necessary a road test of the vehicle
is carried out particularly where safety related items
are concerned.
Dimensions
The dimensions quoted are to design engineering
specification with Service limits where applicable.
