DISASSEMBLY

NOTE:

The following procedures explain how to disassemble the engine with the engine stand fastened to the bell

housing. Some steps may be different if using a different type of engine stand.
1. Remove cylinder head. Refer to 

EM-76, "Exploded View"

.

2. Remove knock sensor.

CAUTION:

Carefully handle knock sensor avoiding shocks.

3. Remove the crankshaft position sensor cover (3), and then

crankshaft position sensor (POS) (2).

CAUTION:

• Avoid impacts such as a dropping.

• Do not disassemble.

• Keep sensor away from metal particles.

• Do not place the sensor in a location where it is exposed

to magnetism.

• Do not reuse O-ring.

4. Remove oil pan (upper and lower). Refer to 

EM-34

.

5. Remove piston and connecting rod assembly:

• Before removing piston and connecting rod assembly, check the connecting rod side clearance. Refer to

EM-101, "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 through the cylinder head side. 

CAUTION:

• Do not damage mating surface with connecting rod cap.

• Do not damage the cylinder wall or crankshaft pin. 

6. Remove connecting rod bearings. 

CAUTION:

Identify original positions for installation, and store the bearings without mixing them up.

7. Remove piston rings from piston. 

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

EM-101, "Inspection"

.

• Use a suitable tool (A) as shown.

CAUTION:

• When removing piston rings, be careful not to damage

the piston.

• Do not damage piston rings by expanding them exces-

sively.

8. Remove piston from connecting rod using the following procedure: 
a. Remove snap rings using snap ring pliers (A).

b. Heat piston to 60 to 70

°C (140 to 158°F) with a heat gun (A).

c.

Push out piston pin using a punch of outer diameter approxi-

mately 18 mm (0.71 in).

9. Remove the main bearing cap.

• Measure crankshaft end play before loosening main bearing cap bolts. Refer to 

EM-101, "Inspection"

.

a. Loosen and remove bolts in several steps in reverse of the

numerical order as shown.

NOTE:

When removing or installing signal plate, use socket (size T40).

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

10. Remove crankshaft (2).

CAUTION:

• Do 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.

• Do not remove signal plate unless it is necessary to do

so.

NOTE:

When removing or installing signal plate, use socket (size T40).

11. Pull rear oil seal out from rear end of crankshaft.
12. Remove main bearing (upper/lower) and thrust bearings from cylinder block and main bearing caps.

CAUTION:

Identify original installation positions, and store the bearings without mixing them up.

13. Remove oil jets.

CAUTION:

Insert the dowel pin of oil jet into the cylinder block dowel pin hole to loosen the bolt.

ASSEMBLY

CAUTION:

Do not reuse O-rings.
1. Fully air-blow engine coolant and engine oil passages in cylinder block, cylinder bore and crankcase to
