Cylinder Head Bolt Torque Sequence
3. Tighten cylinder head bolts a little at a time in the
sequence shown in Fig. 6A1-51, until the specified torque is
reached (60 lbs. ft.).
4. Connect coolant hose to thermostat housing.
5. Install timing belt. See "Camshaft Timing Sprocket".

FLYWHEEL
Removal
With transmission and/or clutch housing and clutch
removed from engine, remove the flywheel.
Repair
The only repair recommended on flywheel used with
conventional clutch is replacement of starter gear in event
gear is worn or otherwise damaged.
Uniformly heat the flywheel gear to temperature which
will expand gear to permit installation (temperature must not
exceed 400°F, 204°C).
As soon as gear has been heated, install on flywheel with
chamfered teeth toward engine side of flywheel.
CAUTION: NEVER heat starter gear red hot as
this will ruin it.
Installation
1. Clean the mating surfaces of flywheel and crankshaft
to make certain there are no burrs.
2. Install flywheel on crankshaft and position to align
dowel hole of crankshaft flange and flywheel.
NOTE: On automatic transmission equipped engines,
the flywheel must be installed with the flange collar to
transmission side.

ENGINE M O U N T S
Engine mounts (Fig. 6A1-53) are the non-adjustable type
and seldom require service. Broken or deteriorated mounts
should be replaced immediately, because of the added strain
placed on other mounts and drive line.

Engine Mounts (Typical)
CHECKING ENGINE MOUNTS
Front Mount
Raise the engine to remove weight from the mounts and
to place a slight tension in the rubber. Observe both mounts
while raising engine. Replace an engine mount if mount has:
a. Hard rubber surface covered with heat check cracks.
b, Rubber separated from a metal plate of the mount.
c. Rubber split through center.
If there is movement between a metal plate of the mount
and its attaching points, lower the engine on the mounts and
tighten the screws or nuts attaching the mount to the engine,
frame or bracket.
Rear Mount
Raise the car on a hoist. Push up and pull down on the
transmission tailshaft while observing the transmission
mount. If the rubber separates from the metal plate of the
mount or if the tailshaft moves up but not down (mount
bottomed out), replace the mount. If there is movement
between a metal plate of the mount and its attaching point,
tighten the screws of nuts attaching the mount to the
transmission or crossmember.
Front Mount Replacement
1. Raise the car on a hoist and support front of engine
to take weight off front mounts.
2. If only one mount is being replaced, remove the
mount-to-engine bracket nut on the mount not being
replaced.
3. Remove the stud nut and two bolts securing mount
to housing support.
4. Remove the three stud nuts securing bracket to
engine. On right side, remove starter brace at starter and, on
air conditioned equipped cars remove compressor rear lower
brace at compressor.
