8. Lower the cover on top of the assembled parts, as in
Fig. 7C-10E. Be sure that the anti-rattle springs are in correct
position and also that the punch marks made before
dismantling are matched to insure retaining the original
balance.
9. Place a bar across the cover and slowly compress,
guiding the holes in the cover over the pressure plate lugs and
all springs into their spring seats in the cover.
10. Assemble adjusting nuts on the eyebolts and screw
them down until their tops are flush with the tops of the
eyebolts. Slowly release pressure of spindle and remove cover
assembly from press.
ADJUSTING LEVERS
While no wear adjustm ent is needed because of the coil
spring design, it is imperative that the clutch release levers
are each set to exactly the same height at the time of rebuild
to insure uniform clutch application. To obtain exactly the
same adjustm ent at each release lever, use gauge plate J - 1048
and release lever height gauge J-6456 as follows:
1. Place gauge plate J-1048 on the flywheel in position
normally occupied by driven plate. See Fig. 7C-11E.
NOTE:
It is recommended that a spare flywheel be
obtained so that this operation may be performed at the
bench.
2. Bolt cover on flywheel with gauge plate center.

NOTE:
On assemblies with three levers, the three flat
machined lands of the gauge plate must be located
directly under the levers.
3. Depress each lever several times with a ham m er
handle to settle all parts into working position, as shown in
Fig. 7C-12E.
4. Position height gauge J-6456-01 on the hub of the
gauge plate and the bearing surface of one lever. Refer to Fig.
7C-13E. Turn adjusting nut until lever is flush with the 12"
step of J-6456-01. Adjust remaining levers in same manner.
5. Stake adjusting nut, as shown in Fig. 7C-14E, to
eyebolt with a dull punch to lock adjustm ent.
6. Loosen the cover to flywheel bolts a turn or two at
a time and in rotation until spring pressure is relieved to allow
clutch and gauge plate to be removed.
