CL

Measure the depth to clutch disc facing rivet heads using cali-
pers. If it exceeds the allowable wear limit, replace clutch disc
and clutch cover as a set. 

Clutch Cover

Check diaphragm spring lever claws for unevenness with the lever
still on vehicle. If they exceed the tolerance, adjust lever height using
the diaphragm adjusting wrench.

Check clutch cover thrust ring for wear or breakage. If wear or
breakage is found, replace clutch disc and clutch cover as a set.

NOTE:

Worn thrust ring will generate a beating noise when tapped at
the rivet with a hammer.

Broken thrust ring will make a clinking sound when cover is shaken up and down.

If a trace of burn or discoloration is found on clutch cover pressure plate to clutch disc contact surface,
repair the surface with sandpaper. If surface is damaged or distorted, replace clutch disc and clutch cover
as a set.

INSTALLATION

1.

Apply recommended grease to clutch disc and main drive shaft spline.

CAUTION:

Be sure to apply grease to the points specified. Otherwise, noise, poor disengagement, or damage
to the clutch may result. Excessive grease may cause slip or quiver. Wipe off any grease oozing
from the parts.

2.

Install clutch disc and clutch cover. Pre-tighten mounting bolts
and install clutch aligning bar.

3.

Tighten clutch cover mounting bolts evenly in two steps in the
order shown in the figure. Refer to 

CL-16, "Removal and Instal-

lation"

 .

4.

Install manual transmission. Refer to 

MT-20, "INSTALLATION"

 .

PRECAUTIONS

PRECAUTIONS

PFP:00001

Precautions for Battery Service

NBS000LD

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT 
BELT PRE-TENSIONER”

NBS000LE

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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal 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
harness connectors.

Precautions for Liquid Gasket

NBS000LF

REMOVAL OF LIQUID GASKET SEALING

After removing mounting bolts and nuts, separate the mating
surface using seal cutter (SST) and remove old liquid gasket
sealing.     

CAUTION:

Be careful not to damage the mating surfaces.

In areas where seal cutter (SST) is difficult to use, use plastic
hammer to lightly tap (1) seal cutter where liquid gasket is
applied. Use plastic hammer to slide seal cutter (2) by tapping
on the side.

CAUTION:

If for some unavoidable reason tool such as flat-bladed
screwdriver is used, be careful not to damage the mating
surfaces.

LIQUID GASKET APPLICATION PROCEDURE

1.

Using scraper, remove old liquid gasket adhering to the liquid
gasket application surface and the mating surface.

Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.

2.

Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
