Generally

a

The
correct

adjustment
of
the

is

most
essential
as
insufficient

clearance
between
the

the

can
be

in
the

CLUTCH
SYSTEM

Bleeding

The
clutch

system
must
be
bled
after
it
has
been
dismantled

or
if

any
part
of
the
circuit
has
been

opened
This

operation

should
also
be
carried
out
if
the
fluid
level
in

the
reservoir
has

been
allowed
to
fall
and

pennit
air
to
enter
the

system

The

presence
of
air
in
the

system
may
be
noticed

by

incorrect
disengagement
of
the
clutch
but
in
any
case
if
air
is

suspected
the
clutch
must

be
bled
in

the
following
manner

Remove
the
dust

cap
from
the
slave

cylinder
bleed
screw

Connect
a

length
of
tube
to
the
bleed
screw
and
immerse
the

47

other
end
of
the

tube
into
a
clean
container

partly
filled
with

brake
fluid

Top

up
the
master

cylinder
reservoir
with
recommended

fluid
and

open
the
bleed
screw

approximately
three

quarters

of
a
turn

Depress
the
clutch

pedal
slowly
and
hold
it

completely

down
re

tighten
the
bleed
screw
and
allow
the

pedal
to
return

slowly

Repeat
the

operation
until
the
fluid

emerging
from
the

tube
is
free
from
air
bubbles
It
should
be
noted
that
assistance
will
be

required
when

carrying
out

bleeding
operations
as
not

only
must
the
fluid

entering
the

glass
container
be
watched
but
also
the
clutch

pedal
has
to
be

operated
and
the
reservoir

topped
up
frequently

throughout
the

procedure

When
the
fluid
is
completely
free
from
air
bubbles
the

bleed
screw
should
be

retightened
on
a
down
stroke
of
the

pedal

Finally
remove
the
