Removal and Installation INFOID:0000000004305174
COMPONENTS
CAUTION:
• Never reuse CSC (Concentric Slave Cylinder). B ecause CSC slides back to the original position
every time when removing transaxle assembly. At th is timing, dust on the sliding parts may damage
a seal of CSC and may cause clut ch fliud leakage. Refer to CL-12, " Removal and Installation " .
• Never bring any grease to the clutch disc faci ng, pressure plate surface and flywheel surface.
• When installing, be careful that grease applied to input shaft does not adhere to clutch disc.
• Never clean clutch disc using solvent.
REMOVAL 1. Remove transaxle assembly from the vehicle. Refer to MT-16, " Removal and Installation " (RS5F91R
models), MT-58, " Removal and Installation " (RS6F94R models).
2. Loosen clutch cover bolts evenly. Then remove clutch cover and clutch disc.
INSPECTION AND ADJUSTMENT AFTER REMOVAL
Clutch Disc • Measure clutch disc runout and spline backlash. If either measure- ment exceeds the specificat ion, replace clutch disc.
• Check clutch disc for burns, discoloration or oil or grease leakage. Replace if necessary.

CAUTION:
Measure flywheel outer face (not on knock pin and clutch cover
mounting hole).
INSTALLATION
1. Clean clutch disc and input shaft splines to remove grease and dust caused by abrasion.
2. Apply recommended grease to clutch disc and input shaft splines. CAUTION:
Be sure to apply grease to the points specified. Ot herwise, noise, poor disengagement, or damage
to the clutch may result. Excessive grease may cause sl ip or shudder. If it adheres to CSC seal, it
will cause clutch fluid l eakage. Wipe off excess grease.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004784387
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 SRS and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipm ent 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.
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
Precaution Necessary for Steering Wh eel Rotation After Battery Disconnect
INFOID:0000000004784348
NOTE:
• This Procedure is applied only to models with Inte lligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecti ng both battery cables with the ignition knob in the
″ LOCK ″ position.
• Always use CONSULT-III 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 pow er 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 al l control units using CONSULT-III.

Recommended Chemical Prod-
uct and Sealant " .
4. Apply liquid gasket without breaks to the specif ied location with the specified dimensions.
• If there is a groove for the liquid gasket application, apply liquid gasket to the groove.
• As for the bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.
• Within five minutes of liquid gasket application, install the mat-
ing component.
• If liquid gasket protrudes, wipe it off immediately.
• Do not retighten nuts or bolts after the installation.
• After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.
