into the groove in the lever, as shown in Fig. 7C-4E.

. Assemble the pressure springs, on the small bosses
of the pressure plate in accordance with Fig. 7C-8E in order
to retain original balance.
NO TIC E: I f there are spaces for more springs than
specified for the particular assembly, or if two different
colors of springs are used, Fig. 7C-8E shows the proper
sequence. It is very important that each group be
arranged in like sequence.
7. Assemble anti-rattle springs in cover. See Fig. 7C-
9E. The spring to the left is in operating position.
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.

A D J U S T IN G LEVERS
While no wear adjustment 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 adjustment 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.
NO TIC E: 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.
NO TIC E: 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 hammer
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 adjustment.
