against the hub of the crankshaft pulley.
Timing
gears are accessible for inspection or replacement
with
the
engine
installed in the vehicle after re moving the radiator, belt drive pulley, and timing
cover.
Should
it be necessary to replace the timing gears, attention must be given to the end float of both
the camshaft and crankshaft and to the running
clearance
of both gears. It is also advisable to
check
both the oil jet and oil passage to the
crank
shaft front bearing to be sure that they are clear.
D-55.
Inspection and
Repair
Check
the general condition of both gears and
inspect for evidence of excessive wear. Replace
excessively worn or damaged gears. Inspect the
cover and replace if bent or damaged. It is recom mended that the crankshaft oil seal in the cover
be replaced when the cover is removed to ensure a
good
seal around the crankshaft. To replace this
seal
with the
engine
in the vehicle
requires
removing
the radiator and water pump.
D-56.
Valves, Springs, and Guides
The
exhaust valves seat on the top of the cylinder
block
with the
stems
extending down through
replaceable valve guides. The exhaust valves are actuated by the camshaft through exhaust valve
tappets. The exhaust valve springs are assembled
and
locked on the lower end of the exhaust valve
stems. The retaining locks are the split type, which
fit in a recess on the valve
stems
and into the taper
in
the valve spring retainers.
Adjustment
of exhaust valves is by means of the
adjusting
screw threaded into the upper end of the
exhaust valve tappets. An exhaust valve rotator used as a valve spring retainer is installed on the
lower end of the exhaust valve.
This
valve rotator,
known
as "Roto Cap", is a spring-loaded
ball
bearing
device. On each lift, or opening stroke of
a
valve, the rotator
gives
the valve a slight positive
clockwise rotation.
The
intake valves operate in valve
guides
in the
cylinder
head and are actuated by rocker arms.
The
rocker arms are actuated by valve push rods
and
the intake valve tappets. The intake valve
springs,
the intake valve spring retainers, and the
intake
valve spring retainer locks make up the
remainder
of the valve operating parts. An intake
valve spring retainer oil seal which encircles the
upper
end of the intake valve
between
the valve
locks and the upper end of the valve spring re
tainer,
controls the passage of oil along the valve
stem and guide.
Note:
When
engine
trouble indicates defective
valves as a possible source of trouble, also check
all
vacuum line connections for possible leaks.
D-57.
Inspection of Valves, Springs,
and
Guides
Clean
the valves on a wire wheel, making sure that
all
carbon is removed from the top and the under
side of the heads and that all gum and varnish
deposits
are removed from the stems.
Polish
the valve
stems
with steel wool or crocus
cloth.
Visually
inspect all valves for warpage,
cracks,
or excessive burning and discard if one of
these
conditions exists. Replace any worn, pitted,
or
corroded valves that cannot be cleaned with a
wire
brush.
Replace any valves when
seats
are pitted, burned, or corroded so badly that they
cannot be cleaned up with a light refacing on a valve refacing machine.
Replace
valves with marks of scoring or abrasion visible on the stem. Replace any valves with bent
stems
which
will
be apparent when the valve is
mounted in the valve refacing machine.
Note:
Use only hard-face exhaust valves for
replacement.
Examine
the
stems
of valves which employ the
ball
bearing rotators.
Wear
marks around the
cir
cumference of the
stems
indicates that the valve is
rotating satisfactorily.
Vertical
heavy pressure
areas
indicate that the valve is not rotating and the valve spring retainer (Roto
Cap)
should be replaced
if
at fault.
Check
the diameter of the valve stem at two or three places along the length of the stem
with
a micrometer. The intake valve stem diameter is .3733" to .3738" [9,482 a
9,495
mm.]. The
exhaust valve stem diameter is .371" to .372"
[9,423
a
9,449
mm.].
Note:
Exhaust
and intake valve springs are
similar
in appearance. They must not be inter
changed as they have different spring
charac
teristics.
Wash
the valve springs thoroughly in solvent.
Visually
examine the springs and replace any that
are
deformed or obviously damaged. Examine for
corrosion
from moisture or acid etching which might

place it with the gasket in position. The rotors
should then rotate freely, providing that end float of the rotors is
less
than the thickness of the gasket
when compressed or .004" [0,102 mm.]. After as
sembling the gear on the pump shaft, check the
running
clearance
between
the gear and pump body with a feeler
gauge.
This
clearance should be
from
.022" to .051" [0,559 a 1,295 mm.].
Pump
output is controlled by a pressure relief valve.
CAUTION:
The oil pressure relief spring is
cali
brated.
Never stretch this spring to alter the relief valve pressure setting. Adjust this setting by the use of shims only. Shims are available that can be
added
between
the retainer and the spring to in
crease pressure. When shims are present, removing
shims
will
decrease pressure.
This
adjustment
will
change the pressure at higher
speeds
but not at idle speed. Safe minimum pres
sure
is 6 psi. [0,4 kg-cm2] at idle, at which point
the oil pressure light
goes
out; and 20 psi. [1,4
kg-cm2] at
2000
rpm. (32 mph. [51 kph.]).
D-66.
Oil Pan
Examine
the oil pan carefully for evidence of cor
rosion,
dents, or other damage. Special attention
should be given to the mounting flange to be sure of proper alignment and a tight seal at the cylinder
block, oil pan, and
engine
front plate. Whenever
the oil pan is removed, it is
best
to install a new
oil
pan gasket.
D-67.
Flywheel
The
flywheel is mounted on the
rear
flange of the
crankshaft.
The crankshaft, flywheel, and clutch
assembly are statically and dynamically balanced
separately and as a unit; therefore,
these
com
ponents
should be assembled in their original
rela
tive positions to maintain this balance.
D-68.
Flywheel Inspection
Clean
the flywheel thoroughly with cleaning sol vent. Inspect the clutch face of the flywheel for
a
burned or scuffed condition or rivet grooves.
Check
the flywheel for run-out or improper mount
ing according to the installation procedure given
in Par.
D-87.
If
the inner ends of the flywheel ring gear
teeth
are
only slightly burred cr snubbed, remove the burrs
and
reshape the
teeth
using a small emery wheel. 59

and place it on the cold
flywheel,
making
certain that the chamfer on the
teeth
is on the crankshaft side of the flywheel. Be
sure
that the ring gear is firmly seated on the fly
wheel. Allow the ring gear to cool slowly to
shrink
it
onto
the flywheel. Do not quench the ring gear;
allow it to slowly air cool.
D-7Q.
Flywheel Pilot Bushing
Inspect
the flywheel pilot bushing in the flywheel.
For
procedure on replacing the bushing, refer to
Par.
1-8.
D-71.
Flywheel Housing
The
flywheel housing, which
encloses
the flywheel
and
clutch is bolted to the
engine
rear
plate and
cylinder
block. The
rear
of the housing provides
the front support for the transmission. Examine the housing for cracks and distortion of the
machined
surfaces. The front face must seat evenly
against the
engine
rear
end plate without evidence
of warpage. The
rear
face must be parallel to the front face. Improper alignment may cause transmission gear disengagement. In addition, the open
ing in the
rear
of the housing, which serves as a
pilot for the transmission, must be concentric with the crankshaft. The flywheel housing should be
checked for alignment after it is installed on the
engine. Refer to Par. D-88.
D-72.
Core Hole Expansion Plug
Any
evidence of coolant leakage around any of
the core
hole
expansion plugs
will
require replace ment of the plug. The expansion plug at the
rear
end of the cylinder block can be driven out with a 24" [60 cm.] length of half-inch bar stock carefully
inserted through the camshaft bore in the cylinder
block. The other core
hole
expansion plugs in the
cylinder
block and cylinder head can be removed
by piercing the center with a sharp tool and prying them out. Before attempting to install a new plug,
clean
the
hole
thoroughly. Apply a thin coat of
sealer on the new plug and install the plug with a

When installing a new crankshaft or
flywheel, replace the tapered dowel
bolts
with
straight snug-fitting special
bolts
provided using
Flywheel
Dowel Bolt Installing Tool Kit W-231 as shown in Fig. D-35 and D-36. Assemble the
crankshaft
and flywheel in proper relation; then in
stall
the straight
bolts
previously used and tighten
securely. Next, use the [13,9 mm.]
drill
to
enlarge the tapered holes. Ream the
holes
with the 5fo" [14,3 mm.] straight reamer and install the
two special flywheel
bolts
with nuts and lock
washers in place of the two tapered dowel
bolts
formerly
used.
This
procedure overcomes the
necessity of reaming special tapered holes.
Tighten
the nuts alternately and evenly until each
is tightened 35 to 41 lb-ft. [4,8 a 5,7 kg-m.].
After
installation check the run-out of the flywheel
with
a
dial
indicator attached to the
engine
plate
as illustrated in
Fig.
D-38. Mount the
dial
indicator
with
the contact button of the indicator resting against the clutch face of the flywheel. Set the
indicator
at zero and rotate the flywheel. Maximum
allowable run-out is .008"
[0,203
mm.] near the
outer
edge
of the
rear
face of the flywheel.
With
the flywheel housing installed temporarily,
the alignment can be checked with a
dial
indicator. Without the clutch installed on the flywheel, a
dial
indicator can be mounted on one of the flywheel bolts. Set the
dial
indicator with the button resting
against the
rear
face of the flywheel housing. Ro
tate
the flywheel, noting the run-out on the
indi
cator.
Maximum allowable run-out is .005" [0,127
mm.].
Relocate the
dial
indicator so that the
button is against the side of the
rear

Slip
the top end of the spring
onto
the
bottom
end
of the valve guide and, with a large screwdriver,
snap the spring and retainer over the tappet ad
justing
screw. Make certain that the two closely wound coils of each spring are at the top (placed up to seat against the block.) See Fig. D-39.
Turn
the crankshaft as necessary to bring each
exhaust valve tappet to its lowest position. Using a
valve spring lifter, compress each exhaust valve
spring,
while holding the valve down, so that the
stem
extends
through the valve spring retainer
far
enough to permit installation of the valve
spring
locks. Heavy lubricating oil or grease
placed on the inside surface of the valve locks
will
