9. Remove the ignition coils. Refer to
EM-40, "Removal and Installation".
10. Remove the rocker cover. Refer to EM-45, "Removal and Installation"
.
11. Remove the front cover, timing chain, and balancer unit. Refer to EM-62, "Removal and Installation"
.
12. Remove the cylinder head. Refer to EM-74, "Removal and Installation"
.
13. Remove oil cooler. Refer to LU-16, "Exploded View"
.
14. Remove the knock sensor. CAUTION:
Carefully handle the sensor and do not drop the sensor.
15. Remove crankshaft position sensor (POS) (2) and O-ring (1).
CAUTION:
• Avoid impacts such as a dropping.
• Do not disassemble.
• Keep it away from metal particles.
• Do not place sensor close to magnetic materials.
• Do not reuse O-ring.
16. Remove the piston and connecting rod assemblies.
a. Position the crankshaft and corresponding connecting rod, to be removed, to the bottom dead center stroke.
b. Remove the connecting rod cap. Number the cap so it can be assembled in the same position.
c. Using a hammer handle or similar tool, push the piston and con- necting rod assembly out of the top of the cylinder block. Num-
ber the piston and rod so it can be assembled in the same
position.
• Before removing the piston and connecting rod assembly,
check the connecting rod side clearance. Refer to EM-96,
"Inspection After Disassembly".
17. Remove the connecting rod bearings. If reusing, num ber them so they can be assembled in the same
position and direction.
CAUTION:
• When removing them, note the installation position. Keep them in the correct order.
18. Remove the piston rings from the piston. • Use a piston ring expander.
• Before removing the piston rings, check the piston ring side
clearance. Refer to EM-96, "Inspection After Disassembly"
.
CAUTION:
• When removing the piston rings, be careful not to damage
the piston.
• Be careful not to damage piston rings by expanding them excessively, if reusing them.

CYLINDER BLOCK
• Check the connecting rod side clearance. Refer to
EM-96, "Inspection After Disassembly".
• After tightening the bolts, make sure that the crankshaft rotates smoothly.
16. Install drive plate (2). • Install drive plate (2), reinforcement plate (3) and pilot con-verter (4) as shown.
• Using a drift with 33 mm (1.30 in) diameter, push pilot con-
verter (4) into the end of the crankshaft (1).
17. Install the knock sensor (1). • Make sure that there is no foreign material on the cylinderblock mating surface or the back surface of the knock sensor.
• Install the knock sensor with the connector (2) facing as shown (A).
• Be sure the knock sensor connector is within 15 ° of centerline
(A).
• Do not tighten the bolts while holding the connector.
• Make sure that the knock sensor does not interfere with other
parts.
CAUTION:
If the knock sensor is droppe d, replace it with new one.
18. Install the crankshaft position sensor (POS).
19. Installation of remaining components is in the reverse order of removal.

CRANKSHAFT SIDE CLEARANCE
• Using a dial gauge (A), measure the clearance between the thrust bearings and the crankshaft arm when the crankshaft is moved
fully forward or backward.
• If the measured value exceeds the limit, replace the thrust bear- ings, and measure again. If it still exceeds the limit, replace the
crankshaft.
