< SERVICE INFORMATION >[VQ35DE]
CYLINDER BLOCK
Measure the outer diameter of
piston skirt with a micrometer.
Piston-to-Cylinder Bore Clearance
Calculate by piston skirt diameter and cylinder bor e inner diameter (direction “Y”, position “B”).
(Clearance) = (Cylinder bore inner diameter) – (Piston skirt diameter).
 If the calculated value exceeds the limit, replace piston and piston pin assembly. Refer to EM-134, "
How to
Select Piston and Bearing".
Re-boring Cylinder Bore
1. Cylinder bore size is determined by adding piston to cylinder bore clearance to piston skirt diameter.
2. Install main bearing caps and main bearing beam, and tighten to the specified torque. Otherwise, cylinder bores may be distorted in final assembly.
3. Cut cylinder bores. NOTE:
 When any cylinder needs boring, all other cylinders must also be bored.
 Do not cut too much out of cylinder bore at a time. Cut only 0.05 mm (0.0020 in) or so in diameter at a
time.
4. Hone cylinders to obtain the specified piston to cylinder bore clearance.
5. Measure finished cylinder bore for the out-of-round and taper. NOTE:
Measurement should be done after cylinder bore cools down.
CRANKSHAFT MAIN JOURNAL DIAMETER
 Measure the outer diameter of cranks haft main journals with a micrometer.
 If out of the standard, measure t he main bearing oil clearance. Then use undersize bearing. Refer to "MAIN
BEARING OIL CLEARANCE".

CRANKSHAFT MAIN JOURNAL DIAMETER
 Measure the outer diameter of crankshaft main journals with micrometer.
 If out of the standard, measure t he main bearing oil clearance. Then use undersize bearing. Refer to "MAIN
BEARING OIL CLEARANCE".
CRANKSHAFT PIN JOURNAL DIAMETER
 Measure the outer diameter of crankshaft pin journal with micrometer.
 If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing. Refer to "CONNECTING
ROD BEARING OIL CLEARANCE".
CRANKSHAFT OUT-OF-ROUND AND TAPER
 Measure the dimensions at four different points as shown in thefigure on each main journal and pin journal with micrometer.
 Out-of-round is indicated by the difference in the dimensions between “X” and “Y” at “A” and “B”.
 Taper is indicated by the difference in the dimensions between “A”
and “B” at “X” and “Y”.
 If the measured value exceeds the lim it, correct or replace crankshaft.
Re-bored size calculation: D = A + B – C
where,
D: Bored diameter
A: Piston skirt diameter as measured
B: Piston to cylinder bore clearance (standard value)
C: Honing allowance 0.02 mm (0.0008 in)
Standard : 63.940 - 63.964 mm (2.5173 - 2.5183 in) dia.
Standard : 51.956 - 51.974 mm (2.0455 - 2.0462 in) dia.
PBIC0127E
Limit: Out-of-round (Difference between “X” and “Y”) : 0.015 mm (0.0006 in)
Taper (Difference between “A” and “B”) : 0.010 mm (0.0004 in)

PRECAUTIONS
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612906
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. 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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
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 NISS AN/INFINITI dealer.
 Improper maintenance, including in correct 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 “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipmen t 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.
Service NoticeINFOID:0000000001328091
 When removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.
 Handle trim, molding, instruments, grille, etc. carefull y during removing or installing. Be careful not to oil or
damage them.
 Apply sealing compound where necessary when installing parts.
 When applying sealing compound, be careful that the sealing compound does not protrude from parts.
 When replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust preven-
tion measures.
