INSTALLATION PROCEDURE
After resurfacing, any flywheel with drilled
balance holes on the clutch side requires
rebalancing by a machine shop.
On vehicles equipped with an automatic
transmission, it may be necessary to install
different components to the flywheel retaining
capscrews. Refer to the Automatic Transmission
Drive Arrangement Assembly Instructions, 5-902,
for installation instructions regarding these
arrangements.
When installing the flywheel, insert two alignment
studs in the crankshaft flange to aid in the
installation.
Refer to Figure 347.
1. Position the flywheel over the dowel pin and
alignment studs on the flywheel mounting
surface at the rear of the crankshaft.
2. Install the flywheel mounting capscrews in
the exposed mounting holes. At this time,
tighten the capscrews finger-tight only.
3. Remove the two alignment studs and insert
the remaining mounting capscrews.
Do not torque capscrews adjacent to each other
in sequence. Doing so may result in uneven
flywheel alignment. Capscrews on opposite sides
of the flywheel should be alternately tightened to
the specified torque.
4. Tighten the capscrews to the specified
torque, 185 lb-ft (250 N
폷
m), alternating from
opposite sides to apply even pressure to the
flywheel (use torque wrench J 24407, or
equivalent).

Valve Lifter Installation
[213 LB]
Check the condition of the valve lifters before
installing them. Replace any lifters that are
broken, damaged or show signs of excessive
wear.
Ceramic lifter rollers will not tolerate high impact
loads. Such loads can crack the ceramic,
resulting in breakage or spalling of the ceramic
roller. Use care when handling the lifters. DO
NOT use a lifter that has been dropped or
subjected to any type of engine failure which
would have subjected the ceramic roller to high
impact loads.
1. Rotate the engine 180 degrees, so that the
bottom of the engine is facing up.
