Clutch Pilot Bearing Staked
chisel to remove staking in end of crankshaft which
keeps bearing in place when transmission is removed
(Fig. 7-6). Remove clutch pilot bearing from hole in
crankshaft.
4. If bearing is a snug fit in crankshaft, use Puller J
4383 and Slide Hammer J 2619-A to remove bearing.
When installing new bearing, see that hole in crank-
shaft is thoroughly clean. Install new bearing with
shielded side toward transmission. Start bearing into
hole and tap into place. Stake slightly, as shown in
Fig. 7-6, to keep bearing in place in case transmission
is removed in the future.
5. If flywheel is to be removed and reinstalled, scribe
marks on flywheel and crankshaft flange, remove
flywheel to crankshaft bolts and remove flywheel.
When reinstalling, clean the mating flanges of fly-
wheel and crankshaft carefully, making sure there are
no burrs on either mounting face. Position flywheel on
crankshaft flange with scribe marks in alignment and
install flywheel to crankshaft bolts and tighten evenly
to 95 lb. ft. torque.
NOTE: Flywheel bolts do not require lock washers.
6. Install clutch and transmission.

STARTER RING GEAR
REMOVE
1. With flywheel removed from vehicle, place the
flywheel, crankshaft side down, on a solid flat surface
or block which is slightly smaller in diameter than the
flywheel.
2. Drive the ring gear off the flywheel, using a suitable
drift and hammer.
NOTE: Keep working around the circumference of the
ring gear to avoid binding the ring gear on the flywheel.
3. Remove all b u m and rough spots from flywheel.
REPLACE
1. Support flywheel in a level position with cylinder
.
,
block side facing up.
2. Support ring gear on metal surface and, using a
blowtorch or acetylene torch, heat ring gear uniformly
on the inside diameter, keeping the torch moving
around the circumference of the fing gear to avoid
localizing hot spots. Under no circumstances should
the ring gear be heated over 400"F., as excessive
heating may destroy the original heat treatment.
3. Pick ring gear up with tongs and place it in position
on flywheel, with ring gear facing the same direction
as the one just removed.
4. Tap ring gear down into place against shoulder on
flywheel. If the ring gear can not be tapped into place
readily, it may be necessary to remove it and apply
additional heat, heeding the caution about overheating
given
in
step 2.
5. Reinstall flywheel in vehicle.
