1999 NISSAN PRIMERA wheel

INSPECITON
Pedal stroke
Check clutch pedal stroke using a 1-meter rule to measure the total pedal stroke. Place end of rule onto the
middle of the clutch pedal pad. Place a book/clipboard on the driver's set to set a reference point, ensure
the book/clipboard does not move during pedal depression. Mark (A) the pedal fully up position on the rule.
Depress the clutch pedal and mark (B) the rule again next to the reference point on the book/clipboard.
Measure the distance between the marks (A and B), this is the actual pedal stroke (S). Check the specified
pedal stroke in the table, adjust actual pedal stroke if necessary (refer toªADJUSTMENTº).
Note:
lDo not use steering wheel as a reference point, angle gives incorrect reading.
lEnsure there is no interference between the floor carpet and clutch pedal when fully depressed.
Pedal free play
Check pedal free play. If out of specification, refer toªADJUSTMENTº.
lPush on the clutch pedal until resistance is felt, and check the distance the pedal moves.
ADJUSTMENT
Pedal stroke
1. Loosen the pedal stopper bolt completely (so there is no contact between pedal and stopper bolt).
2. Adjust pedal stroke to the specified value with the master cylinder push rod.
3. Adjust the pedal stopper bolt until it is just in contact with the pedal, then tighten the lock nut.
4. Once stroke is set to specification, adjust clutch pedal free play.
Pedal free play
1. Adjust pedal free play to the specified value with the master cylinder push rod.
2. Tighten lock nut of the master cylinder push rod.
lPush on the clutch pedal until resistance is felt, and check the distance the pedal moves.

REMOVAL AND INSTALLATION
1. Remove manual transaxle from vehicle. Refer to MT section
ªREMOVAL AND INSTALLATIONº.
2. Remove release bearing by pulling bearing retainers out-
ward.
3. Align retaining pin with cavity of clutch housing and tap out
retaining pin.
CAUTION:
lBe sure to apply grease to the clutch components.
Otherwise, abnormal noise, poor clutch disengagement,
or clutch damage may occur. Wipe the excess grease off
completely, because it may cause the clutch compo-
nents to slip and shudder.
lKeep the clutch disc facing, pressure plate, and flywheel
free of oil and grease.
INSPECTION
lReplace the release bearing if it is seized, damaged, faulty
in rotation direction, or has poor aligning function.
lReplace the withdrawal lever if its contact surface is worn
abnormally.
lReplace the clutch lever if its contact surface is worn abnor-
mally.
lReplace the dust seal if it is deformed or cracked.

Clutch Disc
INSPECTION
Check clutch disc for wear of facing.
Wear limit of facing surface to rivet head:
0.3 mm (0.012 in)
lCheck clutch disc for backlash of spline and runout of facing.
Maximum backlash of spline (at outer edge of disc):
Model 215/225 0.9 mm (0.035 in)
Runout limit:
1.0 mm (0.039 in)
Distance of runout check point (from hub center):
Model 215 102.5 mm (4.04 in)
Model 225 107.5 mm (4.23 in)
lCheck clutch disc for burns, discoloration or oil or grease
contamination. Replace if necessary.
INSTALLATION
lApply recommended grease to contact surface of spline por-
tion.
lToo much lubricant may damage clutch disc facing.

INSPECTION AND ADJUSTMENT
lCheck clutch cover installed on vehicle for unevenness of
diaphragm spring toe height.
Uneven limit:
Model 225 0.7 mm (0.028 in)
Model 215 0.8 mm (0.031 in)
FLYWHEEL INSPECTION
lCheck contact surface of flywheel for slight burns or discol-
oration. Repair flywheel with emery paper.
lCheck flywheel runout.
Maximum allowable runout:
Refer to EM section (ªInspectionº, ªCYLINDER
BLOCKº).
INSTALLATION
lInsert Tool into clutch disc hub when installing clutch cover
and disc.
lTighten bolts to specified torque.
Tightening procedure
a. Tighten all bolts, in numerical order, to 10 - 20 N´m (1.1 -
2.0 kg-m,8-14ft-lb).
b. Tighten all bolts, in numerical order, to 22 - 29 N´m (2.3 -
2.9 kg-m, 17 - 21 ft-lb).
lDo not allow grease to contaminate clutch facing.

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
NCEC0002
The Supplemental Restraint System ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº, used along with a seat
belt, help to reduce the risk or severity of injury to the driver and front passenger in a frontal collision. The
Supplemental Restraint System consists of air bag modules (located in the center of the steering wheel and
on the instrument panel on the passenger side), seat belt pre-tensioners, a diagnosis sensor unit, warning
lamp, wiring harness and spiral cable.
In addition to the supplemental air bag modules for a frontal collision, the supplemental side air bag used
along with the seat belt helps to reduce the risk or severity of injury to the driver and front passenger in a
side collision. The supplemental side air bag consists of air bag modules (located in the outer side of front
seats), satellite sensor, diagnosis sensor unit (one of components of supplemental air bags for a frontal
collision), wiring harness, warning lamp (one of components of supplemental air bags for a frontal collision).
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
lTo 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 dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses (except ªSEAT BELT PRE-TENSIONERº connector) can be
identified with yellow harness connector (and with yellow harness protector or yellow insulation
tape before the harness connectors).
Precautions for On Board Diagnostic (OBD)
System of Engine
NCEC0003
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver
of a malfunction causing emission deterioration.
CAUTION:
lBe sure to turn the ignition switch ªOFFº and disconnect the negative battery terminal before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves,
etc. will cause the MI to light up.
lBe sure to connect and lock the connectors securely after work. A loose (unlocked) connector
will cause the MI to light up due to the open circuit. (Be sure the connector is free from water,
grease, dirt, bent terminals, etc.)
lCertain 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 EL section, ªDescriptionº, ªHARNESS CONNEC-
TORº.
lBe sure to route and secure the harnesses properly after work. The interference of the harness
with a bracket, etc. may cause the MI to light up due to the short circuit.
lBe sure to connect rubber tubes properly after work. A misconnected or disconnected rubber
tube may cause the MI to light up due to the malfunction of the EGR system or fuel injection
system, etc.
lBe sure to erase the unnecessary malfunction information (repairs completed) from the ECM
before returning the vehicle to the customer.
