Install new rear oil seal so that each seal lip is oriented as
shown in the figure.

Install rear oil seal to rear oil seal retainer with rear oil seal
drift (commercial service tool).

Tap until flattened with front edge of rear oil seal retainer. Do
not damage or scratch outer circumference of oil seal.

Make sure the garter spring is in position and seal lips not
inverted.
9. Install rear oil seal retainer.

Apply new engine oil to both oil seal lip and dust seal lip.

Apply a continuous bead of liquid gasket with tube presser
[SST: WS39930000 ( — )] to rear oil seal retainer as
shown in the figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS".
10. Install piston to connecting rod.
a. Using snap ring pliers, install new snap ring to the groove of the piston rear side.

Insert it fully into groove to install.
b. Install piston to connecting rod.

Using industrial use drier or similar tool, heat piston until piston pin can be pushed in by hand without
excess force [approx. 60 to 70 °C (140 to 158 °F)]. From the front to the rear, insert piston pin into piston
and connecting rod.

Assemble so that the front mark on the piston head and the oil
holes and the cylinder No. on connecting rod are positioned
as shown in the figure.
c. Using snap ring pliers, install new snap rings to the groove of the piston front side.

Insert it fully into groove to install.

After installing, make sure that connecting rod moves
smoothly.

11. Using piston ring expander (commercial service tool), install pis-
ton rings.
CAUTION:

When installing piston rings, be careful not to damage
piston.

Be careful not to damage piston rings by expending them
excessively.

Position each ring with the gap as shown in the figure, refer-
ring to the piston front mark.

Install top ring and second ring with the stamped surface fac-
ing upward.
12. Install connecting rod bearings to connecting rod and connecting rod bearing cap.

Before installing connecting rod bearings, apply engine oil to the bearing surface (inside). Do not apply
engine oil to the back surface, but thoroughly clean it.

When installing, align the connecting rod bearing stopper pro-
trusion with the cutout of connecting rod and connecting rod
bearing cap to install.

Ensure the oil holes on connecting rod and that on the corre-
sponding bearing are aligned.
13. Install piston and connecting rod assembly to crankshaft.

Position the crankshaft pin corresponding to connecting rod to be installed onto the bottom dead center.

Apply engine oil sufficiently to the cylinder bore, piston and crankshaft pin journal.

Match the cylinder position with the cylinder No. on connecting rod to install.

Be sure that front mark on piston head is facing front of engine.

Using piston ring compressor [SST: EM03470000 (J8037)],
install piston with the front mark on the piston head facing the
front of engine.
CAUTION:
Be careful not to damage cylinder wall and crankshaft pin,
resulting from an interference of the connecting rod big
end.

14. Install connecting rod bearing cap.

Match the stamped cylinder number marks on connecting rod
with those on cap to install.
15. Tighten connecting rod nuts as follows:
a. Apply new engine oil to the threads and seats of connecting rod bolts and nuts.
b. Tighten connecting rod nuts.
c. Then tighten all connecting rod nuts 60 degrees clockwise. (Angle tightening)
CAUTION:
Use angle wrench (SST) to check tightening angle. Do not
make judgment by visual inspection.

After tightening connecting rod nuts, make sure that crank-
shaft rotates smoothly.

Check the connecting rod side clearance. Refer to EM-262,
"CONNECTING ROD SIDE CLEARANCE" .
16. Install knock sensor.

Install it with its connector facing the rear of engine.

Install the sub-harness with its shorter branch line to the right
bank.
CAUTION:

Do not tighten mounting bolts while holding connector.

If any impact by dropping is applied to knock sensor,
replace it with new one.
NOTE:

Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of knock sensor.

Make sure that knock sensor does not interfere with other parts.
17. Note the following, and assemble in the reverse order of disassembly after this step. Drive plate

When installing drive plate to crankshaft, be sure to correctly
align crankshaft side guide pin and drive plate side guide pin
hole.
–If these are not aligned correctly, engine runs roughly and
“MIL” turns on.

Under Size Bearings Usage Guide

When the specified connecting rod bearing oil clearance is not obtained with standard size connecting rod
bearings, use undersize (US) bearings.

When using undersize (US) bearing, measure the connecting rod bearing inner diameter with bearing
installed, and grind crankshaft pin so that the connecting rod bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft pin to use undersize bearings, keep
the fillet R [1.5 mm (0.059 in)].

When New Cylinder Block and Crankshaft are Used:
1. “Main Bearing Selection Table” rows correspond to main bearing housing grade on rear upper side between cylinder block banks.
2. “Main Bearing Selection Table” columns correspond to main journal diameter grade on front side of crankshaft.

If the measured value exceeds the limit, replace thrust bearings,
and measure again. If it still exceeds the limit, replace crank-
shaft also.
CONNECTING ROD SIDE CLEARANCE

Measure the side clearance between connecting rod and crank-
shaft arm with feeler gauge.

If the measured value exceeds the limit, replace connecting rod,
and measure again. If it still exceeds the limit, replace crank-
shaft also.

When replacing piston and piston pin assembly, refer to EM-255, "HOW TO SELECT PISTON" .
NOTE:

Piston is available together with piston pin as assembly.

Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts,
no piston pin grades can be selected. (Only “0” grade is available.)
PISTON RING SIDE CLEARANCE

Measure the side clearance of piston ring and piston ring groove
with feeler gauge.

If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
replace piston also.
PISTON RING END GAP

Make sure that the cylinder bore inner diameter is within the
specification. Refer to EM-266, "

Lubricate with new engine oil to piston and piston ring, and then
insert piston ring until middle of cylinder with piston, and mea-
sure the piston ring end gap with feeler gauge.

If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
re-bore cylinder and use oversize piston and piston rings. Standard:
