CYLINDER BLOCK
Measure the outer diameter of piston pin with a micrometer.
Connecting Rod Small End Clearance
(Connecting rod small end clearance) = (Connecting rod sm
all end inner diameter) – (Piston pin outer diame-
ter)
• If the measured value is out of the standard, repl ace connecting rod assembly and/or piston and piston pin
assembly.
• If replacing connecting rod assembly, use "CONNECTING ROD BEARING OIL CLEARANCE" to select con-
necting rod bearing.
CYLINDER BLOCK TOP SURFACE DISTORTION
• Using a scraper, remove gasket on the cylinder block su rface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to en ter engine oil or engine coolant passages.
• Measure the distortion on the cylinder block upper face at some different points in six directions with a straight edge and a feeler
gauge.
• If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER
• Install main bearing cap without main bearings install ed, and tighten main bearing cap bolts to the specified
torque. Refer to EM-90, "
Disassembly and Assembly".
• Measure the position shown [5 mm (0.196 in) rearward from main bearing housing front side end surface) in the 2 directions as
shown. The smaller one is the measured value.
• If out of the standard, replace cylinder block and main bearing caps as an assembly.
NOTE:
These components cannot be replaced as a single unit, because they were processed together.

• The identification grade stamped on each part is the
grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
• For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the measurement with the values of each selection table.
• For details of the measurement method of each part, the reuse standar ds and the selection method of the
selective fitting parts, follow the procedures.
Connecting Rod BearingINFOID:0000000005398085
WHEN NEW CONNECTING ROD AND CRANKSHAFT ARE USED
1. Apply connecting rod big end diameter grade stamped (C) on connecting rod side face to the row in the “Connecting Rod
Bearing Selection Table”.
2. Apply crankshaft pin journal diameter grade stamped (B) on
crankshaft front side to the column in the “Connecting Rod Bear-
ing Selection Table”.
3. Read the symbol at the cross point of selected row and column in the “Connecting Rod Bearing Selection Table”.
4. Apply the symbol obtained to the “Connecting Rod Bearing Grade Table” to select connecting rod bearing.
WHEN CONNECTING ROD AND CRANKSHAFT ARE REUSED
1. Measure the dimensions of the connecting rod big end diameter and crankshaft pin journal diameter indi-
vidually. Refer to EM-97, "
Inspection".

HOW TO SELECT MAIN BEARING
When New Cylinder Block and Crankshaft Are Used
1. “Main Bearing Selection Table” rows correspond to main bearing housing grade on left side of cylinder block.
• If there is a corrected stamp mark (B) on cylinder block, use itas a correct reference.
2. Apply main journal diameter grade stamped on crankshaft front side to column in the “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected ro w and column in the “Main Bearing Selection Table”.
4. Apply the symbol obtained to the “Main Bearing Grade Table” to select main bearing. NOTE:
Service part is available as a set of both upper and lower.
When Cylinder Block and Crankshaft Are Reused
1. Measure the dimensions of the cylinder block ma in bearing housing inner diameter and crankshaft main
journal diameter individually. Refer to EM-97, "
Inspection".
2. Apply the measured dimension to the “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected ro w and column in the “Main Bearing Selection Table”.

SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005398096
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 severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 incorrect removal and installation of the SRS can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified 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 Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c 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 3 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000005398097
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK ″ position.
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
4. Perform the necessary repair operation.
