HANDBRAKE
Installation

Check
the
cables
for

signs
of
deterioration

fraying
etc

Examine
the
handbrake
lever
and
ratchet
for
wear
and
renew

as

necessry

Check
the

springs
for
evidence
of
weakness
and
make
sure

that
the
balance
lever
and
bushes
are

satisfactory

Installation
is
a
reversal
of
the
removal
procedure
Make

sure

that
all
sliding

parts
are

greased

BLEEDING
THE
HYDRAULIC
SYSTEM

The
hydraulic
system
must
be
bled
if
the
circuit
has
been

opened
at

any
point
or
if

the
level
of
the
fluid
in
the
master

cylinder
reservoir
has
fallen
too

low
allowing
air
to
enter

the

system

Bleeding
is

usually
a
two
man

operation
as
assistance
will

be

required
to
work
the
brake

pedal
The
master

cylinder

reservoir
must
be

topped

up
constantly
throughout
the

operation

whilst
a
check
is
carried
out
on

the
fluid

expelled

Bleeding
should
be
carried
out
at
the
master

cylinder
nrst

then
from
the
brake
furthest

away
from
the
master

cylinder

and

working
round

finally
to

the
brake
nearest
to
the
master

cylinder
Bleeding
should
therefore
be
carried
out

in
the
follow

ing
order
Rear

and

top

the
reservoir
if

necessary
Clean
the
rele

vant

air
bleed
screw
and
take
off
the

cap

Attach
a
suitable
hose
to
the
bleed
screw
and

place
the

free
end
of

the
hose
in
a

glass
jar
containing
brake
fluid

Open
the
bleed
screw
and

depress
the
brake

pedal
to
allow

the
fluid
to
enter
the

glass
container

Tighten
the
bleed
screw

when
the

pedal
is
fully
depressed
and
allow
the

pedal
to
return

Repeat
the

procedure
until
the
fluid
is

completely
free

from
air
bubbles
then

carry
out
the
same
operation
on
the

other
three
wheels

Top
up
the
fluid
in
the
reservoir
to
the
correct
level
but

do
not
re
use
the
fluid

previously
withdrawn
from
the

system

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
as
follows

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
slide
the

pinion
into

mesh
with
the
flywheel
ring

gear
teeth
when
the
starter
is

operated

When
the
engine
starts
the

pL
lion
is

permitted
to
overrun

the
clutch
and
armature

but
is
held
in
mesh
until
the
shift
lever

is
released
An

exploded
view
of
the
starter

is
shown
in

To
remove
the
starter

motor

proceed
as
follows

Disconnect
the

battery

Disconnect
the
black
