INSPECTION
Checks required
for
the
10"
clutch
are as
follows:
1. Functional
efficiency
of
the
disc
friction
lin-
ings (Items
1 and 8, Fig.-8.1/5) and
conditions
of
mating
metallic
surfaces. The
latter
are
polished,
if
necessary. If the
discs
are im-
pregnated
with
oil
it
is
best
to
replace them,
as washing in solvent and
brushing
are
not
enough.
2.
The
friction
surfaces
of
the pressure plates
should be free from scoring
or
signs
of
ab-
normal wear, and if so
it
is
possible
to reface
them by
turning
them down on a lathe (see
"Fits
and
Tolerances"
table).
3.
The hubs of the driven plates should have no
play on the rivets.
4. The side clearance
of
the
disc
hub
splines
with the splined shafts.
5.
The
condition
of
the throw-out collar
thrust
beanng and of the
clutch
shaft
pilot
bearing
in the flywheel.
6.
Loading
spring
strain
values
versus
specifications
in
"Fits·
and Tolerances'"
table.
7. Sliding surface
conditions
of
throw-out
collar
and support. If wear is
still
within
limits.
the
support can be rotated
180
•,
and
if
not.
replace the parts
if
excessive play causes
grease leakage.

surfaces
of
the forks
of
the pressure plates (Items 3 and
6.
