READING THIS MANUAL
This manual is divided into sections shown on the
contents page, alongside a range of icons, familiar to
service technicians.
Relevant information is contained within each of these
sections. These are further divided into the following
sub-sections which appear at the foot of each page :-
Description and operation.
Fault diagnosis.
Adjustment.
Repair.
Overhaul.
Specifications, Torque.
Service tools.
To avoid repeating information through the sections,
where part of the repair operation impacts on another
section, a cross reference is given to direct the reader
to where the information is sited.
For example:
The maintenance section states the need to renew
V8i drive belt. A cross reference sites this information
in: Section: V8i Engine
- Sub-section: Repairs
- Heading: Drive belt renew.
Sections that contain derivatives such as engines are
further separated within that section.
American terminology.
A few words used in this manual differ to words used
in America. Where this occurs the American word is
placed inside brackets. For example: bonnet [hood],
wing [fender], ramp [hoist].
