Inspection

Use
an

ohmmeter
as

shown

to
test

Apply
the
tester
between
the

slip
rings

check
that

the
resistance
is

approximately
4
4
ohms
at

normal
ambient

temperature
Check
the

conductivity
between

slip
ring
and
rotor

core
as
shown
in

Fig
M
22
if

conductivity
exists
the
field
coil

or

slip
ring
must
be

earthing
and
the
rotor

assembly
should
be

renewed

Cbeck
the

that
there
is

conductivity

retween
the
individual
stator

coil
terminals
as
shown
in

Fig

23
If
there
is
no

conductivity
between
the
individual
terminals

the
stator
is
defective

Check
each
lead
wire

including
the
neutral
wire
as
shown

in

If
there
is

conductivity
between

any
wire
and
the

stator
COTe

the
stator
core

is

earthing
and
the
stator
must

be

replaced

Diodes

Three

positive
diodes
are
mounted
on
the

plate

and
three

negative
diodes
are
mounted
on
the

negative
plate

The
diodes
allow

current
to
flow
in

direction

only
The

diodes
on
the

positive
plate
only
allow
current
to
flow
from

the
terminal
to
the

positive
plate
whilst
the
diodes
on
the

negative
plate
only
allow
current
to
flow
from
the

negative

plate
to
the

A
diode
which
allows
current
to
flow

in
ooth
directions
or
does
not

allow
current
to
flow
in
the

correct
direction
is

check

each

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
blow

to
the
intake
mani

fold
and
the
carburettor
air
cleaner
see

Fig
A
22
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
emission
control

system

The
Nissan
Air

Injection
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

carrying
out

extensive
tests

with
the

necessary
equipment
The

hoses
and
connectors
can
of
course
be
checked
for

signs
of

leakage
and
corrected
as

necessary

The

must

be
removed
from
the
vehicle
if
it
does
not

operate
or
if
a

reduced

quantity
of
fuel
flows
from
the
end
of

hose
Remove

the
pump
from
the
vehicle
and
test
as
follows

Connect
the

pump
to
a

fully
charged
battery
If
the

pump

now

operates
and

discharges
fuel

correctly
the
fault
does
not

lie
in
the

pump
but

may
be
attributed
to

any
of
the

following

causes

Battery
voltage
drop

poor
battery
earth
loose

wiring

loose
connections
blocked
hoses
or
a

faulty
carburettor

If
the

pump
does
not

operate
and

discharge
fuel
when

connected
to
the

battery
then
the

pump
itself
is

faulty
and

must
be
checked
as
follows

First
make
sure
that
current
is

flowing
This
will
be
indica

ted

by
sparking
at

the
tenninals
If
current
flows
the
trouble
is

caused

by
a

sticking

pump
plunger
or

piston
The

pump
must

be
dismantled
in

this
case
and
the

parts
thoroughly
cleaned
in

petrol

If

the
current
does
not
flow
a
coil
or
lead
wire
is
broken

and
the

pump
must

be
renewed
A

reduced
fuel
flow
is
caused

by
a

faulty

or

The

must
