FIG. 5-Release Bearing
and Hub Assembly-
302V8
avoid excessive grease from contaminating
the clutch di
sc.
Hold the bearing inner race and rotate
the
outer
race
while applying pressure to
it.
If the
bearing rotation is rough or
noisy, replace the bearing and hub
assembly.
Misalignment between the engine and
transmission can cause release bearing
failure.
Other symptoms of misalignment
are: transmission jumping out of gear,
especially top
gear,
drive line vibration,
excessive clutch disc spin time resulting
in gear clash, and excessive transmission
gear wear.
PRESSURE PLATE AND COVER
Inspect the surface of the pres-
sure plate for burn marks, scores,
OJ'
ridges. Generally, pressure plate
re-surfacing is not
recommended.
However, minor burn marks, scores,
or ridges may be
removed.
During
the r·esurfacing process, the flat-
ness of the pressut·e plate must
be
maintained.
If the pressure plate
is
badly
heat-checked
or
deeply
scored, replace the pressure plate
and
cover
assembly.
Clean
the
pressure plate
and
flywheel sur-
faces with a crocus cloth to be sure the
surfaces are free from any oil film. Do
not use cleaners with petroleum base, and
do not immerse the pressure plate in the
solvent.
302 C.I.D. ONLY
Place the plate on the floor, be-
ing careful not to score or :scratch
the
surface.
Force each individual
finger down, then release it quickly.
If the finger does not return quick-
ly, a binding condition is indicated,
and the pressure plate should be
replaced.
The pressure plate should be lub-
ricated with lubriplate between the
driving lugs and the edges of the
pressure plate.
Depress the pres-
sure plate finge1·s fully, apply the
lubricant, and then move the fin-
g-er·s up and down until the lubri-
cant is worked in
.
Do not apply ex-
ct>ssive lubricant.
CLUTCH DISC
Inspect the clutch disc facings for oil
or
grease.
Eliminate the source of any
oil or grease before replacing the disc.
An excessive amount of grease in the
release bearing hub will find its way to the
disc
facings.
Too much lubricant in the
transmission or a plugged transmission
vent will force the transmission lubricant
out the input shaft and onto the disc
facings.
Inspect the clutch discs for worn or
loose facings. Check the discs for dis-
tortion and for lose rivets at the
hub.
Check for broken
springs.
Springs loose
enough to rattle will not cause noise when
the car is
operating.
Replace the discs
assemblies if any of these defects are
present. Be especially c-.areful when instal-
ling a new disc to avoid dropping it or
contaminating it with oil or
grease.
PILOT BEARING
Check the fit of the clutch pilot bearing
in the housing of the crankshaft.
The bearing is pressed into the crank-
shaft and should not be loose or cocked
in the bore.
If the bearing is worn or damaged,
replace it with a new service bearing.
