DISTRIBUTOR TIMING Before installing the distributor and oil pump drive
shaft, time engine as follows:
(1) Rotate crankshaft until No.l cylinder is at top
dead center on the firing stroke. (2) When in this position, the timing mark on vi­
bration damper should be under "0" on the timing in­ dicator.
(3) Coat shaft and drive gear with engine oil. In­
stall the shaft so that after the gear spirals into
place, it will index with the oil pump shaft. The slot in top of drive gear should be aligned towards left
front intake manifold attaching bolt hole (Fig. 17).

(2) Install rings and confirm ring side clearance: (a) Install oil rings being careful not to nick or
scratch the piston.
(b) Install the compression rings using Installa­
tion Tool C-4184. The top compression may be in­ stalled with either side up. The second compression

CONNECTING
ROD
BEARINGS
Fit all rods on a bank until completed. DO NOT al­
ternate from one bank to another, because connect­ ing rods and pistons are not interchangeable from
one bank to another.
The bearing caps are not interchangeable and
should be marked at removal to ensure correct as­
sembly.
Each bearing cap has a small V-groove across the
parting face. When installing the lower bearing shell, make certain that the V-groove in the shell is
in line with the V-groove in the cap. This provides
lubrication of the cylinder wall in the opposite bank.
The bearing shells must be installed so that the
tangs are in the machined grooves in the rods and
caps.

Limits of taper or out-of-round on any crankshaft
journals should be held to 0.025 mm (0.001 inch). Bearings are available in 0.025 mm (0.001 inch), 0.051 mm (0.002 inch), 0.076 mm (0.003 inch), 0.254
mm (0.010 inch) and 0.305 mm (0.012 inch) under­
size.
Install the bearings in pairs. DO NOT use a
new bearing half with an old bearing
half.
DO
NOT file the rods or bearing caps.

• INSTALLATION
(1) Be sure that compression ring gaps are stag­
gered so that neither is in-line with oil ring rail gap.
(2) Before installing the ring compressor, make
sure the oil ring expander ends are butted and the
rail gaps located properly (Fig. 14).
(3) Immerse the piston head and rings in clean en­
gine oil. Slide Piston Ring Compressor Tool C-385
over the piston and tighten with the special wrench (part of Tool C-385). Be sure position of rings does
not change during this operation.
(4) Install connecting rod bolt protectors on rod

bolts,
the long protector should be installed on the numbered side of the connecting rod. (5) Rotate crankshaft so that the connecting rod
journal is on the center of the cylinder bore. Be sure connecting rod and cylinder bore number are the same. Insert rod and piston into cylinder bore and
guide rod over the crankshaft journal.
(6) Tap the piston down in cylinder bore, using a
hammer handle. At the same time, guide connecting rod into position on crankshaft journal.
(7) The notch or groove on top of piston must be
pointing toward front of engine. The larger chamfer
of the connecting rod bore must be installed toward
crankshaft journal fillet.
(8) Install rod caps. Be sure connecting rod, con­
necting rod cap and cylinder bore number are the same. Install nuts on cleaned and oiled rod bolts and
tighten nuts to 61 N®m (45 ft. lbs.) torque.
(9) Install the oil pan.
(10) Install the cylinder head.
(11) Install the engine into the vehicle.

CRANKSHAFT
A crankshaft which has undersize journals will be
stamped with 1/4 inch letters on the milled flat on
the No.8 crankshaft counterweight (Fig. 15).
FOR
EXAMPLE: R2 stamped on the No.8 crank­
shaft counterweight indicates that the No.2 rod jour­
nal is 0.025 mm (0.001 in) undersize. M4 indicates
that the No.4 main journal is 0.025 mm (0.001 in) undersize. R3 M2 indicates that the No.3 rod journal and the No.2 main journal are 0.025 mm (0.Q01 in)
undersize. When a crankshaft is replaced, all main and con­
necting rod bearings should be replaced with new
bearings. Therefore, selective fitting of the bearings is not required when a crankshaft and bearings are
replaced.
REMOVAL (1) Remove the oil pan.
(2) Remove the oil pump from the rear main bear­
ing cap. (3) Identify bearing caps before removal. Remove
bearing caps and bearings one at a time. (4) Lift the crankshaft out of the block.

INSPECTION OF JOURNALS The crankshaft connecting rod and main journals
should be checked for excessive wear, taper and scor­
ing. The maximum taper or out-of-round on any crankshaft journal is 0.025 mm (0.001 inch). Journal grinding should not exceed 0.305 mm
(0.012 inch) under the standard journal diameter. DO
NOT grind thrust faces of No.3 main bearing. DO
NOT nick crank pin or bearing fillets. After grind­ ing, remove rough edges from crankshaft oil holes
and clean out all oil passages.

CAUTION:
After any journal
grind,
it is important

that
the
final
paper or cloth
polish
be in the
same
direction as the engine rotates.
INSTALLATION (1) Lightly oil the new upper seal lips with engine

oil.
(2) Install the new upper rear bearing oil seal with
the yellow paint facing towards the rear of the en­
gine.
(3) Position the crankshaft into the cylinder block.
(4) Lightly oil the new lower seal lips with engine

oil.

(5) Install the new lower rear bearing oil seal into
the bearing cap with the yellow paint facing towards
the rear of the engine.

(6)
Apply 5 mm (0.20 in) drop of Loctite 515, or
equivalent, on each side of the rear main bearing cap (Fig. 16). Do not over apply sealant or allow the seal­
ant to contact the rubber seal. Assemble bearing cap
to cylinder block immediately after sealant applica­ tion.

INSTALLATION

Only one main bearing should be selectively fitted
while all other main bearing caps are properly tight­ ened. All bearing capbolts removed during service
procedures are to be cleaned and oiled before instal­ lation. When installing a new upper bearing shell, slightly
chamfer the sharp edges from the plain side.
(1) Start bearing in place, and insert Crankshaft
Main Bearing Remover/Installer Tool C-3059 into oil
hole of crankshaft (Fig. 19).
(2) Slowly rotate crankshaft counterclockwise slid­
ing the bearing into position. Remove Tool C-3059.
(3) Install the bearing cap. Clean and oil the bolts.
Tighten the capbolts to 115 N»m (85 ft. lbs.) torque.
(4) Install the oil pump.
(5) Install the oil pan.

ant to contact the rubber seal. Assemble bearing cap
to cylinder block immediately after sealant applica­
tion.
(8) To align the bearing cap, use cap slot, align­
ment dowel and cap bolts. Do not remove excess ma­
terial after assembly. Do not strike rear cap more
than 2 times for proper engagement.
(9) Clean and oil all cap bolts. Install all main
bearing caps. Install all cap bolts and alternately tighten to 115 N*m (85 ft. lbs.) torque. (10) Install oil pump.
