FOREWORD
This
manual
has
been
written
to
provide
basic
information
for
the
proper

of
the
X

passenger
car.
The information
is grouped in sections.
Each section is
identified by two-digit
numbers.
Each
section
covers
the
service
procedures
for
the
individual
groups
and
sub-groups.
They
are
identified
by
a
number.
The
root
of
the
number
is
taken
from
the
general
sub-group
code now being
used for the Parts
Catalog and the
Service Time Schedule.
This number
identifies
the
service
time
schedule
operation,
parts
catalog
sheet
for
the
part
covered
by the service
procedure, and
the service procedure.
For
the
time
being,
sections
in
the
Parts
Catalog
are
identified
by
a
letter
code
in
place
of a two-digit number.
Each tab index
page contains the
correlation between
the two codes.
HOW TO USE THE
MANUAL
The information
identification number
consists of five
digits, as follows;
a) The first two
digits identify
the section.
b) The third digit
designates the
group within the
section and is
used in conjunction
with
the first two.
c) The last two
digits indicate
an assembly or
task consisting
of several parts.
This number
identifies the sub-group.
It refers to the
sub-group in both
the Parts Catalog
and the
Service Time Schedule.
