Friction

pads
Fig

The
disc
brakes
are
self

adjusting
but
the
friction

pads

should
be
checked
for
wear

every
5
000
km
3
000
miles
and

replaced
if
the
thickness
of

the
friction

lining
on

any

pad
is
less

than
1
0mm
0
004
in
In
effect
this
means
that
renewal
is

necessary
when
the
total
thickness
of

pad
and

lining
is
less
than

8
4mm
0

To

replace
the
friction

pads
proceed
as

follows

Siphon

out
some
of
the
fluid
in
the
master

cylinder
reservoir
Jack

It
should
be
noted
that

it
will
be

necessary
to

DESCRIPTION

A
12
volt

negative
earth
electrical

system
is
used
in
which

the

battery
is

charged
by
an
alternator
In
the
alternator
a

magnetic
field
is

produced
by
the
rotor

which
consists
of
the

alternator
shaft
field
coil

p
le

pieces
and

slip
rings

Output
current
is

generated
in
the
armature
coils
located

in
the
stator
Six
silicon
diodes
are

incorporated
in
the
alternator

caSing
to

rectify
the

alternating
current

supply
A
voltage

regulator
and

pilot
lamp
relay
are
built
in
the

regulator
box

which

nonnally
does
not

give
trouble
or

require
attention

The
starter
motor
is
a

brush

type
series
wound
motor

in

which

positive
meshing
of
the

pinion
and

ring

gear
teeth
are

secured

by
means
of
an

overrunning
clutch

BATTERY
Maintenance

The

battery
should
be
maintained
in
a
clean
and

dry

condition
at
all
times
or
a
current

leakage
may
occur

between

the
terminals
If

frequent
topping

up
is

required
it
is
an

indication
of

overcharging
or
deterioration
of
the

battery

When

refitting
the
cables
clean
them

thoroughly
and
coat

their

terminals
and
the
terminal

posts
with

petroleum
jelly

Check
the
level
of
the

electrolyte
in
the

battery
at

frequent

intervals
and

top
up
if

necessary
to

the
level
mark
on

the

battery
case
with
distilled
water
A

hydrometer
test
should
be

carried
out

to
determine
the
state

of

charge
of

the

battery
by

measuring
the

specific
gravity
of
the

electrolyte
It
should
be

pointed
out

that
the
addition
of

sulphuric
acid
will
not

normally

be

necessary
and
should

only
be
carried
out

by
an

expert
when

required

The

specific
gravity
of
the

electrolyte
should
be
ascertained

with
the

battery

fully
charged
at
an

electrolyte
temperature
of

200C
680F

The

specific
gravity
of
the

electrolyte
decreases
or
increases

by
0
0007
when
its

temperature
rises
or
falls

by
10C
1
80F

respectively

The

temperature
referred

to
is
that
of
the

electrolyte
and

not
the
ambient

temperature
to
correct
a

reading
for
an
air

temperature
it
will
be

necessary
to

add
0
0035
to
the

reading

for

every
50C
above
200C

Conversely
0
0035
must

be
deducted

for

every
SOC
below
200C
Test
each
cell

separately
and
draw

the

liquid
into
the

hydrometer
several
times
if
a
built
in

thermometer
type
is
used

The
correct

specific
gravity
readings
should
be

STARTER
MOTOR
Removal
and
Dismantling

As
previously
stated
the
starter
motor

is
brush

type
series

wound
motor
in
which
the

positive
meshing
of
the

pinion
and

ring
gear
teeth
are
secured

by
an

overrunning
clutch
The
over

running
clutch

employs
a
shift
lever
to

the
flywheel
ring

gear
teeth
when
the
starter
is

operated

When
the
engine
starts

Testing

Disconnect
the

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

The

pts
in

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

system
should
be
lubricated

every
two

years

or
50
000
km

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
