10"
(254 mm) CLUTCH
DESCRIPTION
The spring loaded
clutch
groups
into
a single
unit
two
10", dry, single-plate
clutches
one
of
which controls
the
transmission
and the
other
controls
the power take-off (Fig. B.l/1).
A single
control
pedal disengages the
two
plates
in
succession
during
its
travel.
OPERATION
The correct free travel
of
the pedal
is
Ha"
(35
mm.). It
is
necessary
to
take up the play (Item
B,
Fig. B.l/1) between the
transmission
clutch
release levers (Item
11)
and bearing (Item
12),
while
the
remaining length
of
travel (up
to
the
stop
plate) involves
the
compression
of
the
levers by the bearing.
The levers (Item
11)
act then upon the rods (Item
9)
which
in turn
transmit
the load to the pressure
plate (Item
6),
the separation
of
which
allows
the
disengagement
of
the
transmission
clutch
driven plate (Item
8).
Continuing
on
its
travel (beyond the
stop
plate)
the pedal
allows
the disengagement
of
the P.T.O.
clutch
plate: the levers (Item
13),
pivoted on
pressure plate (Item
6),
during the
transmission
clutch
(diagram
b)
disengagement take up the
play (Item
A)
with
the adjusting screws. These
levers,
with
their
fulcrum
on rods (Item
2),
act
upon
the
screws
thus
moving the pressure plate
(Item
3)
away causing the disengagement
of
the
P.T.O.
clutch
plate (Item
1).
