CAUTION:

Carefully handle knock sensor avoiding shocks.

4.

Remove crankshaft position sensor (POS) and cover.

CAUTION:

• Avoid impacts such as a dropping.
• Never disassemble.
• Keep it away from metal particles.
• Never place the sensor where it is exposed to magnetism.

5.

Remove piston and connecting rod assembly with the following procedure:
• Before removing piston and connecting rod assembly, check the connecting rod side clearance. Refer to

EM-108, "Inspection"

.

a.

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

b.

Remove connecting rod cap. 

c.

Using a hammer handle or similar tool, push piston and connect-
ing rod assembly out to the cylinder head side. 

CAUTION:

• Be careful not to damage matching surface with connect-

ing rod cap.

• Be careful not to damage the cylinder wall and crankshaft

pin, resulting from an interference of the connecting rod
big end.

6.

Remove connecting rod bearings. 

CAUTION:

Identify installation positions, and store them without mixing up.

7.

Remove piston rings form piston. 
• Before removing piston rings, check the piston ring side clearance. Refer to 

EM-108, "Inspection"

.

• Use a piston ring expander (commercial service tool) (A).

CAUTION:

• When removing piston rings, be careful not to damage

the piston.

• Be careful not to damage piston rings by expanding

them excessively.

8.

Remove piston from connecting rod.
• Use a piston pin press stand (SST) and a press to remove the

piston pin.

CAUTION:

Be careful not to damage the piston and connecting rod.
NOTE:
The joint between the connecting rod and the piston pin is a
press fit.

9.

Remove the main bearing cap in the following procedure.
• Measure crankshaft end play before loosening main bearing cap bolts. Refer to 

EM-108, "Inspection"

a.

Loosen and remove bolts in several steps in reverse of the
numerical order shown in the figure.

• TORX socket (size: E14) can be used.

b.

Remove the main bearing cap from the cylinder block while tapping lightly with a plastic hammer.

10. Remove crankshaft (2).

CAUTION:

• Be careful not damage or deform signal plate (1) mounted

on crankshaft.

• When setting crankshaft on a flat floor surface, use a

block of wood to avoid interference between signal plate
and the floor surface.

• Never remove signal plate unless it is necessary to do so.
NOTE:
When removing or installing signal plate, use TORX socket (size
T40).

11. Pull rear oil seal out from rear end of crankshaft.

12. Remove main bearing (upper and lower) and thrust bearings from cylinder block and main bearing cap.

CAUTION:

Identify installation positions, and store them without mixing up.

ASSEMBLY

1.

Fully air-blow engine coolant and engine oil passages in cylinder block, cylinder bore and crankcase to

2.

Install water drain plug (1) to cylinder block as shown in the fig-
ure. 

Use Genuine Liquid Gasket or equivalent. 

3.

Install main bearings and thrust bearings with the following procedure:

a.

Remove dust, dirt, and engine oil on the bearing mating surfaces of cylinder block.

b.

Install thrust bearings to the both sides of the No. 3 journal hous-
ing (B) on cylinder block.

• Install thrust bearings with the oil groove (A) facing crankshaft

arm (outside). 

c.

Install the main bearings (1) paying attention to the direction.
• Install the one with oil holes (A) onto cylinder block and the

one without oil holes onto main bearing cap.

• Before installing main bearings, apply new engine oil to the

bearing surface (inside). Do not apply engine oil to the back
surface, but thoroughly clean it.

• Ensure the oil holes on cylinder block and those on the corre-

sponding bearing are aligned.

• Install the main bearing in the position shown in the figure.
