Use
a
piston
ring
compressor
to
install
the
pistons
through
the
top
of
the
cylbder
bore
Make
sure
that
the
pistons
and
rings
and
the
cylinder
bores
are
lubricated
with
clean
engine
oil
The
pistons
should
be
arranged
so
that
the
F
mark
faces
to
the
front
and
with
the
piston
ring
gaps
positioned
at
1800
to
each
other
Each
piston
must
be
refitted
into
its
original
bore
NOTE
Single

springs
are
used
on

are
used
on
the

with
the

Gean
the

thoroughly
before
installing
the
cylinder

Turn
the
crank
shaft
until
the
No

piston
is
at
T
D
C
on
its
compression
stroke
and
make
sure
that
the
camshaft
sprocket
notch
and
the
oblong
groove
in
the
locating
plate
are
correctly
positioned
Care
should
be
taken
to
ensure
that
the
valves
are
clear
from
the
heads
of
the
pistons
The
crankshaft
and
camshaft
must
not
be
rotated
separately
or
the
valves
will
strike
the
heads
of
the
pistons
Temporarily
tighten
the

Ensure
that
the
mating
marks
on
the
crankshaft
sprocket
face
towards
the
front
Install
the
timing
chain
making
sure
that
the
crankshaft
and
camshaft
keys
are
XJinting
upwards
The
marks
on
the
timing
chain
must
be
aligned
with
the
marks
on
the
right
hand
side
of
the
crankshaft
and
camshaft
sprockets
It
should
be
noted
that
three
location
holes
are
provided
in
the
camshaft
sprocket
See

The
camshaft
sprocket
being
set
to

hole
by
the
manufacturers
A
stretched
chain
will
however
affect
the
valve
timing
and
if
this
occurs
it
will
be
necessary
to
set
the
camshaft
to
the
No
3
location
hole
in
the
camshaft
sprocket
The
chain
can
be
checked
by
turning
the
engine
until
the
No
1
piston
is
at
T
D
C
on
its
compression
stroke
In
this
position
adjustment
will
be
required
if
the
location
notch
on
the
camshaft
sprocket
is
to
the
left
of
the
groove
on
the
camshaft
locating
plate
as
shown
in
the
illustration
The
correction
is
made
by
setting
the
camshaft
on
the
No
3
location
hole
in
the
camshaft
sprocket
the
No
3
notch
should
then
be
to
the
right
of
the
groove
and
the
valve
timing
will
have
to
be
set
using
the
No
3
timing
mark
Install
the
chain
guide
and
chain
tensioner
when
the
chain
is
located
correctly
There
should
be
no

must
be
fitted
if
the

compound
to
the
front
of
the
cylinder

be
carried
out
by
following
the
instructions
previously

noting
the
following
points
Measure
the

The
permissible
amount
of

is
0

Oean
each

then
carefully
examine
the

must
be
discarded
The
valve
seating
face
and
valve
tip
can
be
refaced
if
necessary
but
only
the
minimum
amount
of

should
be
removed

EMISSION
CONTROL
SYSTEM
Crankcase
and
exhaust
gas
emissions
are
controlled
by
two
systems
The
crankcase
emissions
by
a
Positive
Crankcase
Ventila
tion
System
and
the
exhaust
emissions
by
a
Nissan
Air
Injection
System
Brief
descriptions
of
the
systems
together
with
the
test
ing
and
servicing
procedures
are
given
below
Positive

lbis
system
returns
the

to
the
intake
mani
fold
and
the
carburettor
air

see
Fig

Under
part
throttle
conditions
the
intake
manifold
draws
the
gases
through
a
variable
orifice
valve
Control
valve
into
the
combustion
chambers
Ventilating
air
is
then
drawn
from
the
carburettor
air
cleaner
and
passes
throy
gh
a
tube
in
to
the
crankcase
With
the
throttle
fully
open
the
manifold
vacuum
is
insuf
ficient
to
draw
the
gases
through
the
valve
Under
these
conditions
the
gases
flow
tluough
the
tube
to
the
air
cleaner
in
the
reverse
direction
The
gases
are
therefore
retained
or
burnt
to
lessen
the
risk
of
air
pollution
Servicing
and
testing
Once
a
year
or
every
20
000
km
12
000
miles
the
Posi
tive
Crankcase
Ventilation
System
should
be
serviced
as
follows
Check
all
hoses
and
connectors
for
signs
or
leakage
Discon
nect
the
hoses
and
blow
through
them
with
compressed
air
to
make
sure
they
are
not
blocked
Fit
a
new
hose
if
air
cannot
be
forced
through
Check
the
ventilation
control
valve
for
servicability
and
renew
it
if
defective
To
test
the
valve
run
the
engine
at
idling
speed
see
under
IGNITION
TIMING
AND
IDLING
SPEED
and
disconnect
the
ventilation
hose
from
the
rocker
cover
If
the
valve
is
working
correctly
a
hissing
noise
will
be
heard
as
air
passes
through
the
valve
and
a
strong
vacuum
should
be
felt
immediately
a
fInger
is
placed
over
the
valve
inlet
The
valve
cannot
be
serviced
and
must
be
renewed
if
unsatisfactory
Exhaust

The
Nissan
Air

System
comprises
an
air
cleaner
belt
driven
air
injection
pump
check
valve
anti
backfIre
valve
and
the
related
connecting
tubes
and
hoses
The
sealed
pump
is
driven
by
the
engine
and
injects
clean
mtered
air
into
the
exhaust
port
of
each
cylinder
The
clean
air
combines
with
unbumt
gases
as
they
are
expelled
into
the
exhaust
manifolds
and
reduces
the
emissions
to
below
the
permissible
level
required
by
air
pollution
laws
A
modified
carburettor
and
distributor
is
fitted
with
this
type
of
system
The
air
injection
system
is
shown
in
Fig
A
23
The
anti
backfrre
valve
is
controlled
by
intake
manifoLd
vacuum
and
is
fitted
to
prevent
the
exhaust
system
from
back
fIring
during
deceleration
When
decelerating
the
mixture
in
the
intake
manifold
is
too
rich
to
bum
and
ignites
as
it
combines
with
air
injected
by
the
pump
The
valve
shuts
off
the
air
delivered
SI2
to
the
exhaust
system
during
the
flrstpredetennined
period
of
dCl
cleration
and
prevents
back
firing
from
occuring
To
check
valve
is
located
between
the
air
pump
and
air
injection
nozzle
and
is
fitted
to
prevent
a
backflow
of
exhaust
gases
from
entering
the
system
The
valve
doses
when
the
exhaust
manifold
pressure
exceeds
air
injection
pressure
as
It
will
at
high
speed
or
if
the
pump
drive
belt
fails
A
relief
valve
is
mounted
in
the
discharge
cavity
of
the
air
pump
and
is
incorporated
to
hold
the
exhaust
gas
temperatures
to
a
minimum
to
minimize
any
loss
of
power
caused
by
the
air
injection
system
and
to
protect
the
pump
from
excessive
back
pressures
Testing
The
following
tests
should
be
carried
out
to
make
sure
that
the
exhaust
emission
control
system
is
operating
correctly
The
engine
must
be
at
normal
operating
temperature
to
perfonn
the
tests
Before
the
system
can
be
tested
the
engine
itself
must
be
checked
to
ensure
that
It
is
functioning
correctly
Disconnect
the
ant
backflTe
valve
sensing
hose
and
insert
a
plug
into
the
hose
to
close
the
passage
to
the
intake
manifold
Make
sure
that
the
engine
operates
normally
and
then
reconnect
the
parts
Testing
the
check
valve
Run
the
engine
until
it
reaches
its
nonnal
operating
tem
pemture
and
check
all
hoses
and
connectors
for
signs
of
leakage
Disconnect
the
air
supply
hose
from
the
check
valve
and
check
the
position
of
the
plate
inside
the
valve
body
The
plate
should
be
lightly
positioned
against
the
valve
seat
and
away
from
the
air
distributor
manifold
Insert
a
suitable
probe
into
the
valve
and
depress
the
plate
When
released
the
plate
should
return
freely
to
its
position
against
the
valve
seat
Leave
the
hose
disconnected
and
start
the
engine
Slowly
increase
the
engine
speed
to
1500
r
p
m
and
examine
the
valve
to
make
sure
that
the
exhaust
gases
are
not
leaking
The
valve
may
flutter
or
vibrate
at
idling
speed
but
this
is
quite
nonnal
Renew
the
valve
if
necessary
Testing
the
ant
backftre
valve
Run
the
engine
until
it
reaches
its
normal
operating
tem
perature
Check
the
hoses
and
connections
for
signs
of
leakage
Rectify
any
leakage
before
testing
the
vaNe
Accelerate
the
engine
in
neutral
and
allow
the
throttle
to
close
quickly
The
valve
is
operating
correctly
if
the
exhaust
system
does
not
backfire
Further
test
can
be
made
with
the
by
pass
hose
to
the
air
pump
suction
line
disconnected
from
the
valve
Open
and
close
the
throttle
valve
rapidly
Hold
a
fInger
over
the
valve
outlet
and
check
that
air
flows
for
between
a
half
and
one
second
If
air
does
not
flow
or
alternatively
if
it
flows
continuously
for
more
than
two
seconds
the
valve
is
faulty
and
must
be
renewed
Disconnect
the
vacuum
sensing
hose
from
the
valve
Insert
a
suitable
plug
securely
into
the
hose
The
valve
is
not
functioning
correctly
if
the
idling
speed
now
differs
excessively
from
the
speed
at
which
the
engine
operated
with
the
hose
connected
Testing
the
air
pump
Special
tools
are
required
to
test
the
air
pump
The
vehicle
should
therefore
be
taken
to
an
Approved
Agent
capable
of
