3.10 The clutch disc
1 Lining - this will wear 3 Rivets - These secure the
down in use lining and will damage the
2 Marks - “Flywheel Side” pressure plate if allowed
or something similar to contact it
2 Remove the release cylinder (hydraulically actuated models) without
disconnecting the hydraulic line (see Section 8). Support the cylinder out
of the way by a piece of wire from the undercarriage.
3 Referring to Chapter 7 Part A, remove the transmission from the ve-
hicle. Support the engine while the transmission is out. Preferably, an en-
gine hoist should be used to support it from above. However, if a jack is
used underneath the engine, make sure a piece of wood is used between
the jack and oil pan to spread the load. Caution:
The pickup for the oil
pumpis very close to the bottom of the oilpan. If thepan is bentordistorted
in any way, engine oil starvation could occur.
4 To support the clutch disc during removal, install a clutch alignment
tool through the clutch disc hub.
5 Carefully inspect the flywheel and pressure plate for indexing marks.
The marks are usually an X, an 0 or awhite letter. If they cannot be found,
apply marks yourself so the pressure plate and the flywheel will be in the
same alignment during installation.
- 6 Turning each bolt only l/2-turn at a time, slowly loosen the pressure
plate-to-flywheel bolts. Work in a diagonal pattern and loosen each bolt a
little at a time until all spring pressure is relieved. Then hold the pressure
plate securely and completely remove the bolts, followed by the pressure
plate and clutch disc.
Inspection
7 Ordinarily, when a problem occurs in the clutch, it can be attributed to
wear of the clutch disc assembly. However, all components should be in-
spected at this time.
8 Inspect the flywheel for cracks, heat checking, grooves or other signs
of obvious defects. If the imperfections are slight, a machine shop can ma-
chine the surface flat and smooth, which is highly recommended regard-
less of the surface appearance. Refer to Chapter 2 for the flywheel
removal and installation procedure.
9 Inspect the pilot bearing (if equipped) (Section 6).
10 Inspect the lining on the clutch disc. There should be at least 1 mm of
lining above the rivet heads. Check for loose rivets, warpage, cracks, dis-
torted springs or damper bushings and other obvious damage (see illus-
tration). As mentioned above, ordinarily the clutch disc is replaced as a
matter of course, so if in doubt about the condition, replace it with a new
one.
11 Ordinarily, the release bearing is also replaced along with the clutch
disc (see Section 4).
