CLUTCH PILOT BEARING
STAKE TWO PLACES^
F i g . 7-6 C l u t c h Pilot Bearing Staked
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.
5. Install clutch and transmission.
PROCEDURE FOR REMOVING AND INSTALLING
STARTER RING GEAR ON FLYWHEEL
REMOVING RING GEAR FROM F L Y W H E E L
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 b u r r s and rough s p o t s from
flywheel.
INSTALLING RING GEAR ON F L Y W H E E L
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 2.
