Piston Selection Table
Unit: mm (in)
NOTE:

Piston is available together with piston pin as assembly.

Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts, no
piston pin grades can be selected. (Only “0” grade is available.)

No second grade mark is available on piston.
HOW TO SELECT CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft Are Used:
Check pin diameter grade (“0”, “1” or “2”) on front of crankshaft, and
select connecting rod bearing of the same grade.
NOTE:
There is no grading for connecting rod big end diameter.
When Crankshaft and Connecting Rod Are Reused:
1. Measure the connecting rod big end diameter. Refer to EM-258, "CONNECTING ROD BIG END DIAME-
TER" .
2. Make sure that the connecting rod big end diameter is within the standard value.
3. Measure the crankshaft pin journal diameter. Refer to EM-262, "
CRANKSHAFT PIN JOURNAL DIAME-
TER" .
4. Determine the grade of crankshaft pin diameter grade by corresponding to the measured dimension in
“Crankshaft pin journal diameter” column of “Connecting Rod Bearing Selection Table”.
5. Select connecting rod bearing of the same grade.

Under Size Bearings Usage Guide

When the specified connecting rod bearing oil clearance is not obtained with standard size connecting rod
bearings, use undersize (US) bearings.

When using undersize bearing, measure the connecting rod bearing inner diameter with bearing installed,
and grind crankshaft pin so that the connecting rod bearing oil clearance satisfies the standard.

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 rear upper side between cylinder block banks.
2. “Main Bearing Selection Table” columns correspond to main
journal diameter grade on front side of crankshaft.
3. Select main bearing grade at the point where selected row and column meat in “Main Bearing Selection
Table”.
CAUTION:

Initial clearance for No. 1, 5 journal and No. 2, 3, 4 journal is different. Use two different selection
table for each part.

No. 1, 5 journal and No. 2, 3, 4 journal have the same signs but different measures. Do not con-
fuse.
4. Apply sign at crossing in above step 3 to “Main Bearing Grade Table”.
NOTE:

“Main Bearing Grade Table” applies to all journals.

Service parts is available as a set of both upper and lower.

PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectAAS000OH
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.
General PrecautionsAAS000EY

Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
Do not smoke while working on the vehicle.

Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.

When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.

How to Read Wiring DiagramsAAS000E2
CONNECTOR SYMBOLS
Most of connector symbols in wiring diagrams are shown from the terminal side.

Connector symbols shown from the terminal side are enclosed
by a single line and followed by the direction mark.

Connector symbols shown from the harness side are enclosed
by a double line and followed by the direction mark.

Certain systems and components, especially those related to
OBD, may use a new style slide-locking type harness connector.
For description and how to disconnect, refer to PG section,
“Description”, “HARNESS CONNECTOR”.

Male and female terminals
Connector guides for male terminals are shown in black and
female terminals in white in wiring diagrams.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to GW-9, "
Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.

The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).

If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.

After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.

Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard sur-
faces=higher pitch noise/softer surfaces=lower pitch noises/edge to surface=chirping

Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.

Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.

Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.

Tick—(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.

Thump—(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.

Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.

Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.

Weather conditions, especially humidity and temperature, may have a great effect on noise level.
