PREFACE
This
Workshop
Manual
has been
compiled
in
an endeavour
to assist
service
personnel
responsible
for maintenance and
overhaul, in
properly
maintaining
the high
standard of
engineering
achieved
in
the
production
of
Rolls-Royce
and Bentley motor cars.
The
book
is
copiously illustrated with
photographs
and orthographic
reproductions
which are
suitably annotated
in
order
to
provide
quick
reference with
minimum
searching.
Although
all information
contained
in
the Manual was
correct when
going
to
print,
modifications which
may
subsequently develop will be kept
up to date by means of Service
Bulletins.
Information
given
in
the
latest
Bulletin
will
supersede
that
given
in
the Section of the
Manual
to which it refers,
until such times as
the
Manual is re-issued
with the
necessary
amendments.
lnstructions
for
the
maintenance
and overhaul
of the 52 engine and
the
Refrigeration
Systems fitted
to the
Rolls-Royce
and
Bentley cars
are contained
in
individual
volumes.
Special Workshop
Tools referred
to
in
these
publications
and

always
prepared
to answer
queries
or

advice
on individual
servicing
problems,
but it will
assist them if
queries
are accompanied by
the chassis number
of the car.
