PART 8-4-302-351 C.I.D. V8 ENGINES
bearing bores are clean. Foreign material
under the inserts will distort the bearing
and cause a failure.
Place the upper main bearing inserts in
position in the bore with the tang fitting
in the slot provided.
7.
Install the lower main bearing
inserts in the bearing caps.
8.
Dip the lip seal halves in clean
engine
oil.
Install the lip seals in the
bearing cap and block with the undercut
side of the seal toward the FRONT of the
engine as shown in
Fig. 29.
9. Carefully lower the crankshaft
into place. Be careful not to damage the
bearing
surfaces.
10. Check the clearance of each main
bearing following the procedure under
fitting main and connecting rod bearings
in Part 8-1.
11. After the bearings have been
fitted apply a thin coating of oil-resistant
sealer to the rear main bearing cap at the
rear of the top mating surface (Fig. 30).

the oil slinger
groove.
12. Apply heavy engine oil MS to the
journals and
bearings.
13.
Install the rear main bearing cap
with the rear surface flush or slightly
ahead of the rear of the cylinder block.
Install all bearing caps, except the thrust
bearing cap
(No.
3 bearing). Be sure that
the main bearing caps are installed in their
original positions. Tighten the bearing cap
bolts to specifications.
14.
Install the thrust bearing cap with
the bolts
finger-tight.
IS. Pry the crankshaft forward and
pry the thrust bearing cap to the rear (Fig.
44). This will align the thrust surfaces of
both halves of the
bearing.
16, Retain the forward pressure on
the crankshaft. Tighten the cap bolts to
specifications.
17. Check the crankshaft end play
(wear limit 0.012
inches).
18. Install the clutch pilot service
bearing
(Fig. 38).

flywheel attaching
~olts
with oil-resistant
sealer.
Position the rear cover plate on the
block and the flywheel on the crankshaft
flange. Install and tighten the bolts to
specifications.
On a flywheel for a manual-shift
transmission,
use
tool
7SSO-A
to
locate the clutch disc. Install the pressure
plate.
19. Turn the engine on the work
stand so that the front end is up.
20. Position the sprockets and timing
chain on the camshaft and crankshaft (Fig.
23). Be sure the timing marks on the
sprockets are positioned as shown in Fig.
22.
21. Lubricate the timing chain and
sprockets with engine
oil.
22. Install the two piece fuel pump
eccentric, washer and camshaft sprocket
cap screw. Tighten the sprocket cap screw
to specifications. Install the crankshaft
front oil slinger (Fig. 24 ).
23. Position a fuel pump gasket on
the block and install the fuel pump.
Tighten the fuel pump attaching screw and
nut to specification.
24. Remove the front crankshaft seal
from the cylinder front cover with the
tool shown in Fig 19. Oean the cylinder
front cover water pump and the cylinder
block gasket surfaces.
2S. Coat the water pump gasket on
both sides with sealer. Install the water
pump and gasket onto the cylinder front
cover.
26. Coat the cylinder front cover
gasket on both sides with oil-resistant
sealer. Install the cylinder front cover onto
the alignment dowels. Install the timing
pointer and front cover retaining screws.
·
27. Install the pistons and connecting
rods by following steps 1 thru 9 under
Piston and Connecting Rod Installation.
28. Invert the engine on the work
stand. Position the intermediate drive
shaft into the distributor socket. With the
shaft frrmly seated in the distributor
socket, the stop on the shaft should touch
the roof of the crankcase. Remove the
shaft and position the stop as necessary.
29. With
the
stop
properly
positioned,
insert
the
intermediate
driveshaft into the oil pump.
30.
Prime
the oil pump by filling
either the inlet or outlet port with engine
oil.
Rotate the pump shaft to distribute
the oil within the pump
body.
31. Position a new gasket on the
pump housing and install the pump and
shaft as an assembly. Tighten the oil pump
attaching screws to specifications.
32. Clean the gasket surfaces of the
block and oil pan. Coat the block surface
and the oil pan gasket surface With sealer.
Position new gaskets on the block and
position a new seal on the cylinder front
cover and rear main bearing cap. Make
sure the tabs on the seal are over the oil
pan gasket. Install the attaching screws
and tighten them from the center outward
to specifications (one screw secures the
fuel line bracket).
33. Install the front crankshaft oil
seal into the cylinder front cover with the
tool shown in Fig.
20.
34. Lubricate the crankshaft with a
white lead and oil mixture and apply
Lubriplate to the oil seal rubbing surface
of the vibration damper inner hub to
prevent damage to the oil seal.
3S. Line up the crankshaft vibration
damper keyway with the key on the
crankshaft, and then install the vibration
damper on the crankshaft (Fig. 21). Install
the damper cap screw and washer, and
tighten the screw to specifications. Install
the crankshaft pulley.
36. Turn the engine on the work
stand so that the top of the engine is up.
37. Clean the cylinder head and block
gasket
surfaces.
Install the head gasket
8-65
over the cylinder head dowels. Do not
apply sealer to the head gasket surfaces.
38. Place the cylinder head on the
engine. Coat the head bolt threads with
water-resistant sealer, and then install the
bolts.
39. The cylinder head bolt tightening
procedure
is
performed
in
three
progressive steps. Tighten the bolts in
sequence (Fig. 11) to
SO ft-lbs, then to 60
ft-lbs and fmally to specifications. When
cylinder head bolts have been tightened
following this procedure it is not necessary
to retorque the bolts after extended
operation. However, tlie bolts may be
checked and retightened if desired.
40.
Coat the cylinder head mating
surfaces of the exhaust manifold with a
light film of graphite grease.
41. Position the exhaust manifolds on
the cylinder heads and install the attaching
bolts and flat
washers.
Tighten the
attaching bolts to specifications, working
from the center to the
ends.
4 2. Install the spark plugs.
43. Use the hydraulic valve lifter
leakdown tester (page8-9) to fill the lifters
with test
fluid.
Coat the outside of each
valve lifter and lifter bore with heavy
engine oil MS to provide initial lubrica-
tion. Place each lifter in the bore from
which it was removed.
44. Clean the mating surfaces of the
intake
manifold, cylinder heads and
cylinder block.
4S
.
Position new seals on the cylinder
block
and
press
the
seal
locating
extensions into the holes in the mating
surface.
Apply non-hardening sealer at the
four junction points of the seals and
cylinder
heads.
Position
the
intake
manifold gasket onto the block and
cylinder heads with the alignment notches
under the dowels on the cylinder heads.
Be sure the holes in the gasket are aligned
with the holes in the cylinder head.
46. Carefully
lower
the
intake
manifold into position on the cylinder
heads.
47. Be sure the holes in the manifold
gaskets and manifold are in alignment.
Install the intake manifold attaching bolts.
Tighten the intake manifold bolts in three
steps (Fig. 8).
Tighten all bolts in sequence to 8-10
ft-lb.
Tighten all bolts in sequence to lS-20
ft-lb.
Tighten all bolts in sequence to
specifications.
After
completing
the
remammg
assembly steps, operate the engine until it
reaches normal operating temperature,
then retorque the manifold bolts in
sequence to specifications.
