Fig. 1 B-109 Vibration Damper Removal
NOTE: If crankshaft turns before torque is reached,
proceed with belt installation. With belts ins tailed,
tighten damper retaining screw to 90 foot-pounds (122
N m m) torque.
(7) Install damper pulley and retaining screws.
Tighten screws to 30 foot-pounds (41 N*m) torque.
(8) Install drive belts and tighten to specified ten-
sion. Refer to Chapter 1C—Cooling.
Flywheel and Starter Ring Gear Assembly
The starter ring gear is a separate item only on ve-
hicles with manual transmission. On automatic trans-
mission vehicles, the starter ring gear is welded to and
balanced as part of the torque converter drive plate and
is not removeable separately.
Ring Gear Replacement—Manual Transmission (Flywheel
Removed)
(1) Place flywheel on arbor press with steel blocks
equally spaced under gear.
(2) Press flywheel through ring gear.
NOTE: The ring gear can also be removed by breaking
it with a chisel.
(3) Apply heat to expand inside diameter of replace-
ment ring gear.
(4) Press replacement ring gear onto flywheel.
NOTE: On manual transmission, the flywheel is bal-
anced as an individual component and also as part of the
crankshaft assembly. Do not attempt to duplicate origi-
nal flywheel balance holes when installing a service
replacement.
CYLINDER
BLOCK
Disassembly
(1) Drain engine oil.
(2) Remove engine assembly from vehicle as out-
lined in Engine Removal
(3) Use engine stand to support engine assembly.
(4) Remove distributor.
(5) Remove cylinder head covers and gaskets.
(6) Remove rocker arms and bridged pivot assem-
blies. Alternately loosen capscrews one turn at a time to
avoid damaging bridge.
(7) Remove push rods.
(8) Remove intake manifold assembly.
(9) Remove valve tappets.
(10) Remove cylinder heads and gaskets.
(11) Position pistons, one at a time, near bottom of
stroke. Use ridge reamer to remove any ridge from top
end of cylinder walls.
(12) Loosen all drive belts. Remove power steering
pump, air pump and air conditioning compressor, if
equipped.
(13) Remove damper pulley and vibration damper.
(14) Remove timing case cover.
(15) Remove oil pan.
(16) Remove camshaft.
(17) Remove connecting rod bearing caps and inserts
and keep in same order as removed.
NOTE: Connecting rods and caps are stamped with the
number of the cylinder to which they were assembled.
(18) Remove connecting rod and piston assemblies
through top of cylinder bores. Be careful that connecting
rod screws do not scratch connecting rod journals or
cylinder walls. Short pieces of rubber hose slipped over
rod screws will provide protection during removal.
(19) Remove oil pickup tube and screen assembly.
(20) Remove main bearing caps and inserts.
'21) Remove crankshaft.
Cylinder Bore Reconditioning
Measuring Cylinder Bore
Use a bore gauge to measure the cylinder bore (fig.
1B-110). If a bore gauge is not available use an inside
micrometer.
(1) Measure cylinder bore crosswise to block near
top of bore. Repeat measurement at bottom of bore.
