When replacing piston and piston pin assembly, refer to EM-92, "HOW TO SELECT PISTON" .
NOTE:
Piston is available together with piston pin as an assembly.
The piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service
parts, no grades can be selected. (Only grade “0” is available.)
PISTON RING SIDE CLEARANCE
Measure the side clearance of piston ring and piston ring groove
with feeler gauge.
If the measured valve exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
replace piston also.
PISTON RING END GAP
Make sure that cylinder bore inner diameter is within specifica-
tion. Refer to EM-103, "
Cylinder Bore Inner Diameter" .
Lubricate with new engine oil to piston and piston ring, and then
insert piston ring until middle of cylinder with piston, and mea-
sure piston ring end gap with feeler gauge.
If the measured valve exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
re-bore cylinder inner wall and use oversized piston and piston rings.Standard:
Top ring : 0.045 - 0.080 mm (0.0018 - 0.0031 in)
2nd ring : 0.030 - 0.070 mm (0.0012 - 0.0028 in)

Measure the distortion on the cylinder block upper face at some
different points in six directions with straight edge and feeler
gauge.
If it exceeds the limit, replace cylinder block and lower cylinder
block assembly.
NOTE:
Cylinder block cannot be replaced as a single, because it is
machined together with lower cylinder block.
MAIN BEARING HOUSING INNER DIAMETER
Install lower cylinder block without main bearings installed, and
tighten lower cylinder mounting bolts to the specified torque.
Refer to EM-86, "
ASSEMBLY" for the tightening procedure.
Measure the inner diameter of main bearing housing with bore
gauge.
If out of the standard, replace cylinder block and lower cylinder
block assembly.
NOTE:
Cylinder block cannot be replaced as a single, because it is
machined together with lower cylinder block.
PISTON TO CYLINDER BORE CLEARANCE
Cylinder Bore Inner Diameter
Using bore gauge, measure the cylinder bore for wear, out-of-
round and taper at six different points on each cylinder. (“X” and
“Y” directions at “A”, “B” and “C”) (“Y” is in longitudinal direction
of engine)
NOTE:
When determining cylinder bore grade, measure the cylinder
bore at “B” position.
If the measured value exceeds the limit, or if there are scratches and/or seizure on the cylinder inner wall,
hone or re-bore the cylinder inner wall.
Oversize piston is provided. When using oversize piston, re-bore the cylinder so that the clearance of the
piston to cylinder bore satisfies the standard.
CAUTION:
When using an oversize piston, use oversize pistons for all cylinders with oversize piston rings.Limit: 0.1 mm (0.004 in)

Precautions Necessary for Steering Wheel Rotation After Battery DisconnectBBS007TP
NOTE:
This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT
SYSTEM).
Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.
Always use CONSULT-II 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 power 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.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
Precautions for Drain Engine CoolantBBS007TQ
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingBBS007TR
Before starting work, make sure no fire or spark producing items are in the work area.
Release fuel pressure before disconnecting and disassembly.
After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and DisassemblyBBS007TS
When instructed to use special service tools, use specified 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 equivalent, if necessary, to seal out foreign materials.
Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.
When loosening bolts and nuts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified.
Precautions for Inspection, Repair and ReplacementBBS007TT
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationBBS007TU
Use torque wrench to tighten nuts and bolts to specification.

Handling procedure of O-ring is the same as that of fuel damper.
Insert fuel damper straight into fuel tube.
Tighten mounting bolts evenly in turn.
After tightening mounting bolts, make sure that there is no gap between flange and fuel tube.
9. Connect quick connector between fuel feed hose (with damper) and centralized under-floor piping con-
nection as follows:
a. Make sure no foreign substances are deposited in and around centralized under-floor piping and quick
connector, and no damage on them.
b. Thinly apply new engine oil around centralized under-floor piping from tip end to spool end.
c. Align center to insert quick connector straightly into centralized under-floor piping.
Insert quick connector to centralized under-floor piping until
top spool is completely inside quick connector, and 2nd level
spool exposes right below quick connector.
CAUTION:
Hold “A” position as shown in the figure when inserting
centralized under-floor piping into quick connector.
Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.
Insert until you hear a “click” sound and actually feel the
engagement.
To avoid misidentification of engagement with a similar
sound, be sure to perform the next step.
d. Pull quick connector by hand holding “A” position. Make sure it is completely engaged (connected) so that
it does not come out from centralized under-floor piping.
e. Install quick connector cap to quick connector.
Install quick connector cap with arrow on surface facing in
direction of quick connector [fuel feed hose (with damper)
side].
CAUTION:
If quick connector cap cannot be installed smoothly, quick
connector may have not been installed correctly. Check
connection again.
10. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Check Fuel Leakage
1. Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
NOTE:
Use mirrors for checking at points out of clear sight.
2. Start engine. With engine speed increased, check again for fuel leakage at connection points.
CAUTION:
Do not touch engine immediately after stopped, as engine becomes extremely hot.

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluid leak, lubricates leak and exhaust gases leak.
Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
Warm up engine thoroughly to make sure there is no leakage of exhaust gases, or any oil/fluids including
engine oil and engine coolant.
Bleed air from lines and hoses of applicable lines, such as in cooling system.
After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
