Measure the outer diameter of piston pin with a micrometer (A).
Connecting Rod Bushing Oil Clearance
(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) – (Piston pin outer diame-
ter)
• If the measured value is out of the standard, replace connecting rod assembly and/or piston and piston pin
assembly.
• If replacing piston and piston pin assembly, follow the "PISTON TO PISTON PIN OIL CLEARANCE" proce-
dure.
• If replacing connecting rod assembly, follow the "Connecting Rod Bushing Oil Clearance" procedure to
select connecting rod bearing.
CYLINDER BLOCK TOP SURFACE DISTORTION
• Using a scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter 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 (A) and feeler
gauge (B).
• If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER
• Install main bearing cap without main bearings installed, and tighten main bearing cap bolts to the specified
torque. Refer to EM-77, "
Disassembly and Assembly" for the tightening procedure.
• Measure the inner diameter of main bearing housing with a bore gauge.
• Measure the position shown [5 mm (0.20 in)] backward from main
bearing housing front side 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 assembly.

SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001703715
The Supplemental Restraint System such as “AIR 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 whether 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 inoperative, 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 unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001703716
When performing the procedure after removing cowl top cover, cover
the lower end of windshield.
CautionsINFOID:0000000001703717
• When installing rubber bushings, the final tightening must be carried out under unladen conditions with tires
on ground. Oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
- Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
• After servicing suspension parts, be sure to check wheel alignment.
• Self-lock nuts are not reusable. Always use new ones when installing.

Aiming AdjustmentINFOID:0000000001704377
PREPARATION BEFORE ADJUSTING
Before performing aiming adjustment, check the following.
1. Keep all tires inflated to correct pressures.
2. Place vehicle on level surface.
3. See that there is no-load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant, engine oil filled up to correct level and full fuel tank, spare tire, jack and tools are properly
stowed.
LOW BEAM AND HIGH BEAM
1. Turn headlamp low beam ON.
2. Use adjusting screw to perform aiming adjustment.
3. Insert the tool through the adjusting screw access hole to avoid damage to the adjusting screw.
