if
this
occurs
it

can

be

is
made

by
setting

DESCRIPTION

Either
a

diaphragm
spring
or

coil

spring
type
clutch

is

fitted
to

the
vehicle
The

component
parts
of
the

diaphragm

spring

are
shown
in

Fig

l
and
the

component
parts

of
the
coil

spring
clutch
are
shown
in

Fig

The
clutch
is
of
the

single
dry
plate
type
consisting
of

the
drive

plate
clutch
coveT
and

pressure
plate
and
release

bearing

The
driven

plate
comprises
a

flexible
disc
and

splined
hub

which
slides
on
the

clutch
shaft
Friction
linings
are

rivetted
to

both

sides
of
the
disc

The
clutch
cover

and

pressure
plate
are
combined

by
nine

spring
setting
bolts
The

diaphragm
is
dished
to

maintain
a

constant

pressure
on
the

pressure
plate
which
in
turn
holds

the
driven

plate
in
contact
with
the

flywheel
The
release

bearing

is
a
sealed

type
ball

bearing
mounted
on
a

bearing
sleeve
Both

bearing
and
sleeve
are
operated

by
the
withdrawalleveT
when

the
clutch

pedal
is

operated

The
clutch

pedal
actuates
a
master

cylinder
which
transmits

fluid

under

pressure
to
a
slave

cylinder
The
movement
of

the

slave

cylinder
piston
operates
the

via

a
