( 6) Adjust the clutch release levers
·until each of the three feeler blades have the
same slight "drag" or "feel" while being
pushed in and out. Tighten the release lever
nuts to decrease "drag" and loosen to in-
crease "drag."
( 7) Stake the release lever nuts.
IMPORTANT
When removing the clutch cover
assembly from the fixture, loosen
the housing clamps first, then re-
move the compression nut. This
will avoid throwing unequal
strain on the release levers.

RELEASE LEVERS WITH FIXTURE
C-411.
1936-42-Determine the clutch assem-
bly model number which is stamped on the
clutch cover. Then, by using this number as
a guide, select the proper thickness gauge
and feeler blade from the chart shown on
page 93. Adjust the release levers as follows:
( 1 ) Insert the proper thickness gauge
under the "Y" extension gauge and place
them in that sequence on the main screw of
the fixture. Then, with the extending end of
the "Y" extension gauge directly over a
clutch release lever, tighten the extension
gauge Jock nut ( 6, fig. 10).
( 2 ) Insert the end of the feeler blade
between the release lever and the extended
end of the "Y" gauge and turn the clutch
release lever adjusting nut until the feeler
blade can just be moved, with a slight drag,
between the "Y" gauge and the clutch re-
lease finger.
( 3) Loosen the extension gauge lock
nut and repeat the procedure of measuring
for all of the clutch release levers.
( 4) When adjustments have be,~n
made on all release levers, recheck the meas-
urements with the feeler gauge. They must
all have equal clearance adjustment.
CAUTION
Proper operation of the clutch is
dependent upon accurate adjust-
ments of the release levers. They
must all be adjusted to exactly
the same height above the ma-
chined surface of the pressure
plate so as to maintain. paral-
lelism of the pressure plate and
the flywheel. This adjustment
cannot be accomplished by set-
ting the levers parallel to the face
of the release bearings after the
clutch has been assembled to the
flywheel because of variations in
thickness of the driven plate. The
most accurate method is to adjust
the levers by using the special
clutch compressing and adjusting
fixture and following the settings
as given in the foregoing.
( 5) Pressure may then be relieved on
the cover plate and the assembly installed
on the flywheel making certain that the cen-
ter punch marks on the flywheel and clutch
cover register as they were marked before
the assembly was removed from the fly-
wheel.
