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

this
occurs
it
will
be
necessary
to
set
the

can
be
checked
by

The
correction
is
made
by
setting

FLUID
COUPLING
The
water
pump
is
equipped
with
a
fluid
coupling
on
vehicles
fitted
with
an
air
conditioner
The
fluid
coupling
Limits
the
maximum
fan
speed
to
approximately
3000
r
p
ro
and
eliminates
noise
and
loss
of
power
at
high
engine
speeds
A
fault
in
the
coupling
may
be
caused
by
the
entry
of
foreign
matter
If
a
fault
developes
the
oupling
must
be
removed
and
dismantled
and
the
interior
cleaned
by
washing
in
solvent
The
condition
of
the
seal
and
bearing
must
be
care
fully
checked
and
the
coupling
replaced
if
the
latter
items
have
become
blackened
If
oil
leaks
occur
it
will
be

CENTRIFUGAL
ADVANCE
MECHANISM
Special
equipment
is
required
to
check
the
advance
characteristics
It
is
possible
however
to
carry
out
an
exam
ination
of
the
caffi
assembly
and
the
weights
and
springs
to
ensure
that
the
earn
is
not
seizing
Lift
off
the
distributor
cap
and
turn
the
rotor
anti
clock
wise
When
the
rotor
is
released
is
should
return
to
the
fully
retarded
position
without
sticking
If
it
does
not
return
to
the
fully
retarded
position
it
will
be
necessary
to
check
for
dirt
and
weak
springs
It
should
be
noted
that
any
wear
in
the
mechanism
or
lose
of
spring
tension
will
upset
the
advance
characteristics
and
cause
unsatisfactory
engine

VACUUM
ADVANCE
MECHANISM
The
diaphragm
of
the
vacuum
advance
mechanism
is
mechanically
connected
to
the
contact
breaker
plate
The
rise
and
fall
of
inlet
manifold
depression
causes
the
diaphragm
to
move
the
contact
breaker
plate
to
advance
or
retard
the
ignition
If
the
vacuum
control
unit
fails
to
function
correctly
a
check
can
be
carried
out
to
ensure
that
the
contact
breaker
plate
is
moving
freely
and
that
the
three
steel
balls
at
the
top
and
oottom
of
the
plate
are
adequately
lubricated
Also
make
sure
that
the
vacuum
inlet
pipe
is
not
blocked
or
leaking
and
is
securely
tightened
Leakage
may
be
due
to
a
defective
diaphragm
which
should
be
renewed
along
with
any
other
faulty
part
of
the
mechanism
