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
the
Workshop Manual
are listed and illustrated
in a further
publication.
Personnel
of
Rolls-Royce
Service
Departments at
Hythe
Road,
Willesden, London
N.W.l0,
and
at
Pym's
Lane,
Crewe,
are
always
prepared
to answer
queries
or
give
advice
on individual
servicing
problems,
but it will
assist them if
queries
are accompanied by
the chassis number
of the car.

SECTION

UNIFIED SCREW THREADS
The need for a common standard of
screw
threads
in
the United
Kingdom, Canada and
the United
States
of
America
has led
to an agreement between
the countries
concerned to use UNIFIED THREADS
of mutually
acceptable form,
pitch
and diameter.
There
are three
types of unified
thread:
1. Unified Coarse.
2.
Unified
Fine.
3. Unified
Special.
These unified threads are clearly identified
by the
standard system
of markings, as illustrated in
Figure
Al.
There is little
difference
between
the form
of
the
American national thread and the
unified thread;
therefore the new threads are largely interchangeable
with S.A.E. standards. They
are not, however,
interchangeable with
BSF, and although BSW have
the same number of threads
per
inch as
the Unified
National
Coarse series, interchanging is
not recom-
mended due to a difference
in
the thread form.
The following
types
of thread
are
used on nuts,
bolts
and castings fitted to Rolls-Royce and
Bentley
cars.

used.
All sizes above

have been classified
by
Rolls-Royce and
Bentley
Motors
as Unified
Special
and have 16
threads
per
inch.

Coarse Thread is not used.
