REMOVAL
(1) Remove transmission
(Refer to Group 21, Transmission And Transfer
Case.)
(2) Remove clutch cover and disc as described in
this section.
(3) Remove bolts that attach pilot bearing retainer
to flywheel.
(4) Remove pilot bearing and retainer.
(5) Remove flywheel bolts.
(6) Grasp flywheel firmly and work it off the
crankshaft flange (side to side or up and down). Be
sure to maintain a firm grip as the flywheel is heavy.
(7) Remove the o-ring from the crankshaft flange,
or the mounting shoulder of the flywheel (Fig. 9).
(8) Clean the flywheel in solvent.
INSPECTION
Examine flywheel mounting surfaces, clutch con-
tact surface, and ring gear. Check condition of fly-
wheel hub and attaching bolts. Replace flywheel if
hub exhibits cracks in the area of attaching bolt
holes. Replace ring gear if the teeth are damaged.
Resurface the flywheel if the clutch contact surface is
scored or rough (refer to flywheel finishing and ring
gear replacement information in this section.
Check flywheel runout if misalignment is sus-
pected. Runout should not exceed 0.08 mm. Measure
flywheel face runout with a dial indicator (Fig. 8).
Mount the indicator on a stud installed in the engine
block or in one of the flywheel attaching bolt holes.
Face runout can be corrected by resurfacing if neces-
sary. Surface grinding equipment is recommended for
this purpose. Stock removal should not exceed 0.25
mm.
INSTALLATION
(1) Clean crankshaft flange before mounting the
flywheel. Dirt or grease on flange surface may cock
flywheel causing run-out.
(2) Install new o-ring in the flywheel mounting
flange (Fig. 9). Use grease to hold the ring in place.
