22. Remove the crankshaft (A).
CAUTION:
• Do not damage or deform the signal plate (B) while
mounted on the crankshaft.
• When setting the crankshaft on a flat surface, use a block of wood to avoid interferen ce between the signal plate
and the surface.
• Do not remove signal plate unless it is necessary.
23. Pull the rear oil seal off of the rear end of the crankshaft. CAUTION:
Do not damage the crankshaft or cylinder block when removing the rear oil seal.
NOTE:
When replacing the rear oil seal without removing the cy linder block, use a suitable tool to pull it out from
between crankshaft and block.
24. Remove the main bearings and thrust bearings from the cylinder block and lower cylinder block. CAUTION:
Identify and number the bearings, if reusing th em, so that they are assembled in the same position
and direction.
25. Remove oil jets (A) if necessary.
ASSEMBLY
1. Using compressed air, clean out the coolant and oil passages in the cylinder block, the cylinder bore and
the crankcase to remove any foreign material.
WARNING:
Use approved safety glasses to protect your eyes.
2. Install the drain plugs on the cylinder block. • Apply Silicone RTV Sealant. Use Genuine Silicone RTV Seal ant, or equivalent. Refer to
GI-21, "Recommended Chemi cal Products and Sealants"
.

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.

3. While securely holding the hexagonal part in pulley center of
drive belt auto-tensioner, move in the direction of arrow (loosen-
ing direction of drive belt auto-tensioner) using suitable tool.
WARNING:
Avoid placing hand in a locat ion where pinching may occur
if the holding tool accidentally comes off.
CAUTION:
Do not loosen the drive belt auto-tensioner pulley bolt. (do
not turn it counterclockwise. ) If turned counterclockwise,
the complete drive belt auto-t ensioner must be replaced as
a unit, including pulley.
4. Insert a rod approximately 6 mm (0.24 in) in diameter through the rear of drive belt auto-tensioner into retain ing boss to lock drive belt auto-tensioner pulley.
NOTE:
Leave drive belt auto-tensioner pulley arm locked until belt is installed again.
5. Loosen drive belt and then remove it from the other pulleys.
INSTALLATION
1. Install the drive belt onto all of the pulleys.
CAUTION:
Confirm belts are completely set on the pulleys.
2. Release drive belt auto-tensioner, and apply tension to belt. WARNING:
Avoid placing hand in a location wh ere pinching may occur if the holding tool accidentally comes
off.
CAUTION:
Do not loosen the auto-te nsioner pulley bolt. (Don't turn it counterclockwise. If turned counter-
clockwise, the complete auto-tensioner mu st be replaced as a unit, including pulley.
3. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
4. Confirm tension of belt at indicator is within the possible use range. Refer to EM-19, "Checking Drive
Belts".
5. Install the fender protector side cover RH. Refer to EXT-26, "FENDER PROTECTOR : Removal and
