If
bearing is a snug fit in crankshaft, use puller
J
4383
and slide hammer J 2619-A to remove bear-
ing.
When installing new bearing, see that
hole
in
crankshaft
is thoroughly clean.
Install
new bearing
with
shielded side toward transmission. Start bear-
ing 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.
4. 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 flywheel 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.

ON
FLYWHEEL
REMOVING
RING
GEAR
FROM
FLYWHEEL
1. 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.
NO
TE:
Keep working around the circumference
of
the ring
gear
to
avoid
binding the ring
gear
on
the
flywheel.
3.
Remove all burrs and rough
spots
from
flywheel.
INSTALLING
RING
GEAR
ON
FLYWHEEL
1. Support flywheel in 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 uni-
formly on the inside diameter, keeping the torch
moving around the circumference of the ring 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 in posi-
tion 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 over-
heating given in
step
