CRANKSHAFT PIN JOURNAL DIAMETER

Measure the outer diameter of crankshaft pin journal with a
micrometer.

If out of the standard, measure the connecting rod bearing oil
clearance. Then use undersize bearing. Refer to EM-147,
"CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT OUT-OF-ROUND AND TAPER

Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with a 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 limit, correct or replace crankshaft.

If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then
select the main bearing and/or connecting rod bearing. Refer to EM-148, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-147, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT

Place V-block on precise flat table, and support the journals on
the both end of crankshaft.

Place a dial indicator straight up on the No. 3 journal.

While rotating crankshaft, read the movement of the pointer on a
dial indicator. (Total indicator reading)

If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation

Install connecting rod bearings to connecting rod and connect-
ing rod cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-129, "
ASSEMBLY" for the tightening proce-
dure.

Measure the inner diameter of connecting rod bearing with an
inside micrometer.
(Oil clearance) = (Connecting rod bearing inner diameter) – (Crank-
shaft pin journal diameter) Standard : 51.956 - 51.974 mm (2.0455 - 2.0462 in) dia.
PBIC0127E
Limit:
Out-of-round (Difference between “X” and “Y”) : 0.002 mm (0.0001 in)
Taper (Difference between “A” and “B”) : 0.002 mm (0.0001 in)

If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer
to EM-137, "
HOW TO SELECT CONNECTING ROD BEARING" .
Method of Using Plastigage

Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.

Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding
oil holes.

Install connecting rod bearings to connecting rod and connecting rod bearing cap, and tighten connecting
rod bolts to the specified torque. Refer to EM-129, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.

Remove connecting rod bearing cap and bearings, and using
the scale on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation

Install main bearings to cylinder block and main bearing caps,
and tighten main bearing cap bolts with main bearing beam to
the specified torque. Refer to EM-129, "
ASSEMBLY" for the
tightening procedure.

Measure the inner diameter of main bearing with a bore gauge.
(Oil clearance) = (Main bearing inner diameter) – (Crankshaft main
journal diameter)

If the calculated value exceeds the limit, select proper main bearing according to main bearing inner diam-
eter and crankshaft main journal diameter to obtain the specified bearing oil clearance. Refer to EM-138,
"HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage

Remove engine oil and dust on crankshaft journal and the surfaces of each bearing completely.

Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding
oil holes.

Install main bearing to cylinder block and main bearing cap, and tighten main bearing bolts with main
bearing beam to the specified torque. Refer to EM-129, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Never rotate crankshaft. Standard : 0.034 - 0.059 mm (0.0013 - 0.0023 in)
(actual clearance)
Limit : 0.070 mm (0.0028 in)
PBIC1149E

CONNECTING ROD BOLT OUTER DIAMETER

Measure the outer diameter “d” at position shown in the figure.

If the reduction appears in a position other than “d”, regard it as
“d”.

When “d” exceeds the limit (when it becomes thinner), replace
connecting rod bolt with new one.
DRIVE PLATE

Check drive plate and signal plate for deformation or damage.
CAUTION:

Do not disassemble drive plate.

Do not place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.

If anything is found, replace drive plate.
OIL JET

Check nozzle for deformation and damage.

Blow compressed air from nozzle, and check for clogs.

If it is not satisfied, clean or replace oil jet.
OIL JET RELIEF VALVE

Using a clean plastic stick, press check valve in oil jet relief
valve. Make sure that valve moves smoothly with proper reac-
tion force.

If it is not satisfied, replace oil jet relief valve. Standard : 7.90 - 8.00 mm (0.3110 - 0.3150 in)
Limit : 7.75 mm (0.3051 in)

PRECAUTIONS
Revision: 2006 July 2007 FX35/FX45
[VK45DE]PRECAUTIONSPFP:00001
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectNBS006ST
NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

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 NVIS/IVIS, an electrically controlled steering lock
mechanism 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 Coolant and Engine OilNBS003HB
Drain engine coolant and engine oil when engine is cooled.
Precautions for Disconnecting Fuel PipingNBS003HC

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 DisassemblyNBS003HD

When instructed to use SST, use specified tools. Always be careful to work safely, avoid forceful or unin-
structed operations.

Exercise maximum care to avoid damage to mating or sliding surfaces.

Cover openings of engine system with tape or the equivalent, 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 specified, do exactly as specified. Power tools may be
used where noted in the step.
Precautions for Inspection, Repair and ReplacementNBS003HE
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationNBS003HF

Use torque wrench to tighten bolts or nuts to specification.
