WITHDRAWAL
LEVER

Adjusting

The
correct

adjustment
of
the
clutch
withdrawal
lever
is

most
essential
as
insufficient

clearance
between
the
clutch

release

bearing
and
the

diaphragm
will
cause
the
clutch
to

slip

On
the
other
hand
an
excessive
clearance
will

prevent
the
clutch

from

disengaging
correctly

The
clearance
between

the
release

bearing
and

diaphragm

or
release
levers
can
be

adjusted
in
the

following
manner

Slacken
the
locknut

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
bleed
tube
and

replace
the
dust

cap

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

Friction

pads

The

are
self

but
the
friction

pads

should
be
checked
for
wear

and
then

every

be

replaced
if

on

any
