assembled in
their
respective original
positions
thus
maintaining the dynamic balance
of
the unit
as set at
the
factory.
Clutches
can be disassembled
without
using any
specialized
tooling,
as follows:
gradually cross-loosen the nuts
(8,
Fig.
8.1/15)
and then remove the P.T.O. clutch
pressure plate
(2)
and the dished spring
(3,

INSPECTION
Check wear
of
the
friction
linings
of
discs
(1
and
6,
Fig.
8.1117)
vs. tabulated
limits.
If
the
discs
are
impregnated
with
oil we recommend replacing
them.
Examine the condition
of
the
friction
surfaces on
the engine flywheel, pressure plates
(2
and
7,
Fig.
'8.1117)
and cover
(4).
If necessary, these sur-
faces can
be machined
to
a maximum depth
of
.008"
(0.2
mm). In case the inner side
of
clutch
cover
(4)
is re-cut, also
the
mating surface
with
the flywheel
must
be refaced in order to restore
the dimension mentioned above.
Check the return springs
(16,
Fig.
8.1116).
Check the flexible
disc
for
flexibility.
CLUTCH ASSEMBLY
Prior
to
the assembly
of
the
clutch
unit
we
recommend lubricating the release lever pivot
pins
with
a
film
of
Multi-Purpose grease.
Reassemble the
clutch
on the work bench as
follows:
