IntroductIon

OUf
intention
in

writing
this
Manual
is
to

provide
the

reader
with

all
the
data
and
in

formation

required
to
maintain
and

repair
the
vehicle
However
it
must
be
realised
that

special
equipment
and
skills
arc

required
in
some
caseS
to

carry
out
the

work
detailed

in
the
text
and
we

do
not

recommend
that
such
work
be

attempted
unless
the
reader

possesses
the

necessary
skill

and

equipment
It
would
be
better
to

have
an

AUTHQRISED

DEALER
to

carry
out
the

work

using
the

special
tools
and

equipment
available
to

his
trained
staff
He
will
also
be
in

possession
of
the

genuine
spare
parts
which
may
be

needed
for

replacement

The
information
in
the
Manual
has
been
checked

against
that
provided
by
the
vehicle

manufacturer
and
any

peculiarities
have
been
mentioned
if

they
depart
rom
usual

work

shop
practice

A
fault

finding
and
trouble

shooting
chart
has
been
inserted
at

the
end
of
the
Manual
to

enable
the
reader
to

pin
point
faults
and
so
save

time
As
it
is

impossible
to
include

every

malfunction

only
the
more
usual
ones
have
been
included

A

composite
conversion
table
has
also
been
included
at

the
end
of
the
manual
and
we

would
recommend
that
wherever

possible
for

greater
accuracy
the
metric
system
units

are
used

Brevity
and

simplicity
have
been
our
aim
in

compiling
this
Manual

relying
on

the
number

ous
illustrations
and
clear
text

to
inform
and
instruct
the
reader
At
the

request
of
the

many
users
of
our
Manuals
we
have
slanted
the
book
towards

repair
and
overhaul
rather

than
maintenance

Although
every
care
has
been

taken
to
ensure

that
the
information
and
data
are

correct

WE
CANNOT

INTRODUCTION

The
1400
1600
cc

and
1800
cc

engines
are
four

cylinder

in
line
units
with
a

single
overhead
camshaft

and

fully
balanced

five

bearing
crankshaft

The
valves
are

operated
through
rockers

which
are

directly
activated

by
the

earn
mechanism

The
crankshaft
is
a

special
steel

forging
with
the
centre

main

bearing

equipped
with
thrust
washers

to
take

up
the
end

thrust

of
the
crankshaft
The

special
aluminium

pistons
are
of

the
strut

construction
to

control
thermal

expansion
and

have

two

compression
rings
and
one
combined
oil

ring

The

gudgeon
pins
have

special
hollow
steel
shafts

and
are

a

fully
floating
fit
in

the

pistons
and
a

press
fit

in
the

connecting

rods

The
aluminium

alloy
cylinder
head
contains

wedge
type

combustion
chambers

and
is
fitted
with
aluminium

bronze
valve

seats

for
the
intake
valves

and
heat
resistant
steel
valve
seats

for
the
exhaust

valves

The
cast

iron
camshaft
is
driven

by
a
double
row
roller

chain
from
the
crankshaft

pulley

The

engine
is

pressure
lubricated

by
a
rotor

type
oil

pump

which
draws
oil

through
an

oil
strainer
into
the

pump
housing

and
then
forces

it

through
a
full
flow

oil
filter

into
the
main
oil

gallery

ENGINE

Assembling

Before

make
sure
that
all

components
are

perfectly
clean
It
is

always
advisable
to

pay

particular
attention
to
the
