17. Install the wiring loom in the
clips located on the right bank rocker
arm cover. Install the ignition coil
primary and secondary wires, tem-
perature sending unit wire, and the
oil pressure sending unit wire.
18. Install the distributor cap and
spark plug wires as a unit. Install
the spark plug wires on the rocker
arm covers and spark plugs.
19. Fill the crankcase to the re-
quired level with the proper type and
grade of lubricant.
20. Add fluid to the power steering
reservoir to bring the fluid up to
the required level.
21. Start the engine. Check the
oil pressure at the instrument panel
indicator. Check for oil and coolant
leaks.
22. Run the engine until normal
operating temperature is indicated
and perform or check the following
items:
Check for fuel, oil, coolant and
vacuum leakage.
Check and adjust the
~nitial
tim-
ing.
Perform carburetor idle and mix-
ture adjustments.
Perform transmission linkage ad-
justments, if necessary.
23. On a car with an air condi-
tioner, adjust the fast idle control
linkage.
24. Install the hood assembly and
adjust it, if necessary. Remove the
masking tape from the hood.
25. Install the carburetor fresh air
inlet duct assembly on the exhaust
manifold. Install the carburetor air
cleaner.
26. Remove the fender covers.
Close the hood and road test the
car.
CAMSHAFT REAR BEARING BORE
PLUG REPLACEMENT
1. Remove the flywheel, follow-
ing the procedure under "Flywheel
Removal."
2. Drill a
1f2
inch hole in the
center of the camshaft rear bearing
bore plug.
3. Remove the plug with the
clutch pilot bearing remover (tool
7600-E).
4. Clean the plug bore recess
thoroughly.
5. Coat the bore with an oil-re-
sistant sealer. Position the plug in
the bore with the flange facing the
front of the engine. Drive the plug
inward until it is seated.
6. Install the flywheel, following
the procedure under "Flywheel In-
stallation."
GROUP 8-ENGINE
MAIN AND CONNECTING ROD
BEARING REPLACEMENT
It is necessary to check the condi-
tion of all crankshaft main and con-
necting rod journals before replace-
ment procedures are performed.
If
a crankshaft has journals that
are damaged or worn below specifi-
cations, the crankshaft must be re-
moved from the engine for grinding
or replacement purposes.
It
will be
necessary to remove the engine from
the car and disassemble it to replace
the crankshaft.
The standard main and connect-
ing rod bearing inserts are a selec-
tive fit and do not require line ream-
ing to size upon installation. Do not
file or lap bearing caps and webs
or use shims to obtain the proper
bearing clearance.
Selective fit bearings are available
for service in two standard sizes
only. Each size carries a different suf-
fix to the part number. They can be
identified by a daub of red or blue
color dye. Red marked bearing in-
serts decrease the clearance.
Undersize bearings which are not
selective fit are available for use on
journals that are undersize or have
been reground.
MAIN BEARING
REPLACEMENT
Check and replace one bearing
at a time, leaving the other bear-
ing caps securely attached to the
cylinder block.
1. Remove the spark plugs. Re-
move the high tension lead wire
from the coil terminal. Connect the
auxiliary starter switch to the starter
relay.
2. Drain the crankcase and re-
move the oil pan and oil pump.

3. Remove the main bearing cap
to which new bearings are to be in-
stalled. Remove the upper bearing
insert with tool 6331-E. Insert the
tool into the crankshaft oil hole
(Fig. 36) and rotate the crankshaft
in the direction of normal rotation
(clockwise). Use tool 6331-E with
care. to avoid damage to the bear-
ing insert.
4. Clean and inspect each bear-
ing insert carefully. Bearings that
have a scored, chipped or worn sur-
face will have to be replaced (Part
8-1, Section 3) . Dirt or other for-
eign material under a bearing
insert may have distorted the
bearing.
Sound
judgment
and
proper inspections are necessary
when diagnosing bearing failures.
5. Clean and inspect the main
bearing
journals
for
cracks,
scratches, grooves, or score marks.
Dress minor
imperfections
care-
fully with a fine oil stone. If the
journal is damaged it
will
have
to be ground to size for the next
undersize service bearing.
6. Check the main bearing journal
for an out-of-round condition with
a dial indicator (tool 6565) and hold-
ing fixture (tool 4201-D). Secure
tool 4201-D to the oil pan rail with
an oil pan mounting bolt. (Fig. 37).
Position the dial indicator on "0".
Revolve the crankshaft and check
the indicator reading. If out-of-round
exceeds specifications, the crankshaft
must be replaced.
7. Wipe oil and dirt from all con-
tacting surfaces of the crankshaft,
bearing inserts and bearing caps.
8. When
replacing
standard
bearings with new bearings, it is
