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.

• 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.

PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951676
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three mi nutes before performing any service.
Precaution for Draining CoolantINFOID:0000000009460515
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000009460516
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000009460517
• When instructed to use special service tools, use the spec ified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
• Exercise maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or the equiva lent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specif ied, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000009460518
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000009460519
• Use torque wrench to tighten bolts or nuts to specification.
