collar is worn, the fork usually is worn also. Any worn
parts should be replaced. Figure 7-32 shows damage
related to the throwout bearing, which you might find
during inspection, along with possible reasons the damage
occurred.
Throwout bearing assembly repair
Some throwout bearings are an integral part of the
bearing collar. These are replaced as a unit. Many
throwout bearings, however, are a press fit onto the bear-
ing collar. The assembly can be repaired by replacing the
bearing or collar—whichever is in need of repair.
Replacement bearings must be pressed onto the col-
lar after the old bearing is removed. To remove the
throwout bearing, press it from the collar using a bench
vise or press. Adapters may be necessary to properly per-
form the pressing operation. Press on the new throwout
bearing. It should be fully seated on the shoulder of the
bearing collar when complete. Refer to Figure 7-33.
Caution: Do not apply driving force through
the bearing elements when installing the
throwout bearing.

E—To reassemble, install the release levers and apply springs.
Basically, install the release levers by reversing the procedure
for removal. If new springs are used, install them using the
sequence shown; otherwise, return the springs to their original
positions.
G—To ensure uniform clutch application, the release levers
must be set to equal heights. Place the gauge plate on the
spare flywheel, and place the pressure plate assembly over it.
The gauge plate occupies the position normally occupied by
the clutch disc and simulates installed component positions.
Bolt the clutch cover to the flywheel. Note that spacers or shims
may be used instead of gauge plate.
F—With the pressure plate assembly positioned on the arbor
press as per original setup, slowly apply pressure to the clutch
cover. The drive-lug openings in the clutch cover should fit over
the drive lugs; apply springs should fit into their seats, as
shown. Screw the eyebolt adjustment nuts onto the eyebolts
until their tops are flush. Slowly release the arbor press and
remove the assembly.
H—Position the height gauge on the hub of gauge plate. Turn
the eyebolt adjustment nut until the lever is flush with the height
gauge. Adjust all levers in this manner. Stake all adjustment
nuts when finished so they will not loosen in service. A straight-
edge can also be used and placed across the cover. Levers can
then be set to a height at some specified distance down from
the straightedge. Remove the clutch cover from the flywheel,
loosening the bolts gradually until spring pressure is relieved.
