c. Install main bearings paying attention to the direction.
Main bearing with oil hole (B) and groove (C) goes on cylinder
block. The one without them goes on lower cylinder block.
Before installing main bearings, apply engine oil to the bear-
ing surface (inside). Do not apply engine oil to the back sur-
face, but thoroughly clean it.
When installing, align main bearing stopper protrusion to cut-
out of cylinder block and lower cylinder block.
Ensure the oil holes on cylinder block and those on the corresponding bearing are aligned.
5. Install crankshaft to cylinder block.
While turning crankshaft by hand, check that it turns smoothly.
6. Install lower cylinder block.
NOTE:
Lower cylinder block cannot be replaced as a single part, because it is machined together with cylinder
block.
Apply a continuous bead of liquid gasket with the tube presser [SST: WS39930000( — )] to lower
cylinder block as shown in the figure.
7. Inspect the outer diameter of lower cylinder block bolt. Refer to EM-133, "
LOWER CYLINDER BLOCK
BOLT OUTER DIAMETER" .
8. Install lower cylinder block bolts in numerical order as shown in the figure as follows:
a. Apply new engine oil to threads and seat surfaces of lower cylinder block bolts.
b. Tighten lower cylinder block bolt (No.17 to 26) in numerical order
as shown in the figure.
c. Repeat step b.
d. Tighten lower cylinder block bolts (No.1 to 16) in numerical order
as shown in the figure.
NOTE:
Use TORX socket (size E14) for bolts No.1 to 16.

If there is stamped mark on ring, mount it with marked side
up.
Mount second ring with cut out side down.
Position each ring with the gap as shown in the figure refer-
ring to the piston front mark.
Check the piston ring side clearance. Refer to EM-126, "PISTON RING SIDE CLEARANCE" .
11. 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 connecting rod bearing stopper protru-
sion with cutout of connecting rods and connecting rod bear-
ing caps to install.
Ensure the oil hole on connecting rod and that on the corre-
sponding bearing are aligned.
12. Install piston and connecting rod assembly to crankshaft.
Position 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 number 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)] (A)
or suitable tool, install piston with the front mark on the piston
head facing the front of engine.
CAUTION:
Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an interference of the connecting rod big
end.Stamped mark:

22. Install knock sensors.
Install knock sensor so that connector faces rear of engine.
After installing knock sensor, connect harness connector, and
lay it out to rear of engine.
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.

Undersize 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 – 1.7 mm (0.059 – 0.067 in)].

When replacing piston and piston pin assembly, refer to EM-119, "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 cylinder bore inner diameter is within the specifi-
cation. Refer to EM-129, "
Cylinder Bore Inner Diameter" .
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:
Top ring : 0.040 - 0.080 mm (0.0016 - 0.0031 in)
2nd ring : 0.030 - 0.070 mm (0.0012 - 0.0028 in)

Piston Pin Outer Diameter
Measure the outer diameter of piston pin with micrometer.
Connecting Rod Bushing Oil Clearance
(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) – (Piston pin outer diame-
ter)
If the measured value exceeds the limit, replace connecting rod assembly and/or piston and piston pin
assembly.
If replacing piston and piston pin assembly, refer to EM-119, "HOW TO SELECT PISTON" .
If replacing connecting rod assembly, refer to EM-131, "CONNECTING ROD BEARING OIL CLEAR-
ANCE" to select the connecting rod bearing.
Factory installed parts grading:
Service parts apply only to grade “0”.
