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

thoroughly
and
remove
carbon
deposits
with
a
blunt
scraper
Remove
any
rust
which
has
accumulated
in
the

INSERTS
Replacing
The

should
be
replaced
if
they
show
signs
of
pitting
and
excessive
wear
The

can
be
removed
by
boring
out
to
a
depth
which
will
cause
them
to
collapse
although
care
must
be
taken
not
to
bore
beyond
the

DESCRIPTION
Either
a
diaphragm
spring
or
coil
spring
type
clutch
is
fitted
to
the
vehicle
The
component
parts
of
the
diaphragm
spring
clutch
are
shown
in
Fig

l
and
the
component
parts
of
the
coil
spring
clutch
are
shown
in
Fig

The
clutch
is
of
the
single
dry
plate
type
consisting
of
the
drive
plate
clutch
coveT
and
pressure
plate
and
release
bearing
The
driven
plate
comprises
a
flexible
disc
and
splined
hub
which
slides
on
the
clutch
shaft
Friction
linings
are
rivetted
to
both
sides
of
the
disc
The
clutch
cover
and
pressure
plate
are
combined
by
nine
spring
setting
bolts
The
diaphragm
is
dished
to
maintain
a
constant
pressure
on
the
pressure
plate
which
in
turn
holds
the
driven
plate
in
contact
with
the
flywheel
The
release
bearing
is
a
sealed
type
ball
bearing
mounted
on
a
bearing
sleeve
Both
bearing
and
sleeve
are
operated
by
the
withdrawalleveT
when
the
clutch
pedal
is
operated
The
clutch
pedal
actuates
a
master
cylinder
which
transmits
fluid
under
pressure
to
a
slave
cylinder
The
movement
of
the
slave
cylinder
piston
operates
the
clutch
withdrawal
lever
via
a
push

can
be
found

it
will
be
necessary

DESCRIPTION
Three
types
of
transmission
are
available
for
the
Datsun
models
covered
by
this
manual
Either
a
three
speed
gearbox
a
four
speed
gearbox
or
three
speed
automatic
transmission
can
be
fitted
The
three
and
four
speed
gearboxes
are
equipped
with
nchromesh
on
all
forward
gears
with
the
three
speed
gearbox
operated
by
a
steering
column
gearchange
system
and
the
four
speed
gearbox
by
a
floor
mounted
gear
lever
Two
types
of
synchromesh
are
used
in
the
four
speed
gearboxes
Either
Borg
Warner
or
Servo
types
may
be
fitted
The
gearboxes
differ
only
in
the
synchromesh
devices
whereby
the
baulk
rings
synchronize
the
coupling
sleeve
with
the
main
shaft
gear
on
the
Warner
gearbox
This
action
is
accomplished
by
a
synchrcrring
on
the
