Vibration Damper Removal
Installation
(1) Align key slot of the vibration damper with
crankshaft key and tap damper onto crankshaft.
(2) Install vibration damper retaining screw and
washer. Tighten screw to 80 foot-pounds (108 N®m)
torque.
(3) Install damper pulley and retaining capscrews.
Tighten screws to 20 foot-pounds (27 N®m) torque.
(4) Install drive belt(s) and tighten to specified ten-

Flywheel and Starter Ring Gear Assembly
The starter ring gear can be replaced only on vehicles
with manual transmission. The starter ring gear is
welded to and balanced as part of the converter drive
plate on vehicles with automatic transmissions. The en-
tire drive plate and ring assembly must be replaced on
automatic transmission equipped vehicles.
Ring Gear Replacement (Manual Transmission)
(1) Position flywheel on arbor press with steel
blocks equally spaced under gear.
(2) Press flywheel through ring gear.
NOTE: Ring gear can also be removed by breaking
with chisel
(3) Apply heat to expand inside diameter of replace-
ment ring gear.
(4) Press flywheel onto replacement ring gear.
NOTE: On manual transmission equipped cars, the fly-
wheel is balanced as an individual component and also
as part of the crankshaft assembly. Do not attempt to
duplicate original flywheel balance holes when instal-
ling a service replacement. Service flywheels are bal-
anced during manufacture.
CYLINDER BLOCK
Disassembly
(1) Remove engine as outlined under Engine
Removal.
(2) Place engine assembly on engine stand.
(3) Remove intake and exhaust manifolds.
(4) Remove cylinder head cover and gasket.
(5) Remove rocker arms and bridged pivot assem-
blies. Back off each capscrew a turn at a time to avoid
breaking the bridge.
(6) Remove push rods.
(7) Remove cylinder head and gasket.
(8) Remove valve tappets.
(9) Remove drive pulley and vibration damper.
(10) Removing timing case cover.
(11) Remove timing chain and sprockets.
(12) Remove camshaft.
(13) Position pistons, one at a time, near bottom of
stroke and use a ridge reamer to remove any ridge from
top end of cylinder walls.
(14) Remove oil pan and gaskets.
(15) Remove oil pump.
(16) Remove connecting rod bearing caps and inserts
and retain in same order as removed.
NOTE: Connecting rods and caps are stamped with the
number of the cylinder to which they were assembled.
(17) Remove piston and connecting rod assemblies
through top of cylinder bores.
NOTE: Be careful that connecting rod bolts do not
scratch the connecting rod journals or cylinder walls.
Short pieces of rubber hose slipped over the rod bolts
will prevent damage to the cylinder bores or crankshaft.
(18) Remove main bearing caps and inserts.
(19) Remove crankshaft.
