Ring Gear Replacement—Manual Transmission (Flywnwl
(1) Place flywheel on arbor press with steel blocks
equally spaced around perimeter and under ring gear.
(2) Press flywheel down through ring gear.
NOTE: the ring gear can also be removed by breaking
it with a chisel
(3) Apply heat to expand inside perimeter of re
placement ring gear.
(4) Press replacement ring gear onto flywheel.
NOTE: The flywheel is balanced as an individual com
ponent and also as part of the crankshaft assembly. Do
not attempt to duplicate original flywheel balance holes
when installing a service replacement.
CYLINDER BLOCK
(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 bridge and pivot assemblies and rocker
arms. Alternately loosen capscrews, one turn at a time,
to avoid damaging bridge.
(7) Remove push rods.
NOTE: Retain bridges, pivots, rocker arms, push rods
and tappets in cylinder sets to facilitate installation in
original locations.
(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 ridge, if any, from
top end of cylinder walls.
(12) Loosen all drive belts. Remove power steering
pump, air pump and air conditioner 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 retain in same order as removed.
NOTE: Connecting rods and caps are stamped with the
number of the associated cylinder.
(18) Remove connecting rod and piston assemblies
through top of cylinder bores. Ensure that connecting
ENGINES 1B-99
rod bolts do not scratch connecting rod journals or cylin
der walls. Short pieces of rubber hose slipped over rod
bolts 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
Cylinder Bora MeasirtMit
Use a bore gauge to measure the cylinder bores (fig.
1B-152). 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.
(2) Determine taper by subtracting smaller dimen
sion from larger dimension.
(3) Turn measuring device 120° and repeat step (1).
Then turn another 120° and repeat measurements.
(4) Determine out-of-roundness by comparing dif
ference between measurements taken 120° apart.
If the cylinder taper does not exceed 0.005 inch (0.127
mm) and the out-of-roundness does not exceed 0.003
inch (0.076 mm), true the cylinder bore by honing. If the
cylinder taper or out-of-round condition exceeds these
limits, bore and then hone cylinder for an oversize
piston.
