The
thermostat
can
be

tested

by
suspending
it
with
a

thermometer
in
a

container
ftlled
with
water

Heat
the
water

gradually
and
stir
it
to

obtain
a
uniform

temperature
Maintain

a
constant

check
of
the

temperature
and

make
sure

that
neither
the
thermostat

or
thermometer

touch

the
sides
of
the
container
or
false

readings
will
be
obtained

The
thermostat
should

begin
to

open

a

temperature
of

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

necessary
to

replace
the

water

pump
assembly
with
the

coupling
After

cleaning
the
unit
refill

with
11
5
cc
silicon
oil

using
a

suitable

syringe

FUEL
PUMP

Testing

Disconnect
the
fuel
hose
from

outlet
Connect

a
hose
with

an
inner
diameter
of
approximately
6
mm
0

in
to

the

pump
outlet
and

place
a

container
under
the
end
of

the

pipe
Note
that
the
inner

diameter
of
the

pipe
must
not
be

too

small
or

the
pipe
will
be

incapable
of

delivering
the
correct

quantity
of
fuel
when

testing
Hold
the
end
of
the
hose
above
the

level
of
the

pump
and

operate
the

pump
for
more
than
IS

seconds
to
check
the

delivery
capacity
The

capacity
should
be

400
cc

U
S

pts
in
one
minute
or
less
The

pump
must

be
removed
from
the
vehicle
if
it
does
not

operate
or
if
a

reduced

quantity
of
fuel
flows
from
the
end
of
the
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
pump
inlet
or

discharged
valve
or
blocked
filter

mesh
The

pump
must

of
course

be
dismantled
and
serviced
as

necessary

STEERING
Maintenance

The

system
should
be
lubricated

every
two

years

or
50
000
km
30
000
miles
whichever
comes

fIrst

A
lithium
base

multipurpose
grease
must
be
used
for
the

rack
and

pinion
and
rack
and
tie
rod

joints
The

plug
on
the

steering
gear
housing
should
be
removed
and
a

grease
nipple

fitted
so
that
the
recommended

quantity
of
10
to

15

gram

0
35
to

0
53
oz
of

grease
can
be

injected
Remove
the

grease

nipple
and

replace
the
plug
when
lubrication
is

completed

The

grease
reservoir
on
the
tube
side
should
be

replenished
when

the
level
of

grease
falls
to

approximately
one
third
ofits

capacity
