On-Vehicle Inspection and ServiceEGS000AF
OIL PUMP PULLEY HYDRAULIC PRESSURE INSPECTION
Before starting following procedure, check tension of belt.
1. Raise vehicle. Connect oil pressure gauge between oil pump
discharge connector and high pressure hose. Then bleed the
hydraulic circuit.
2. Start engine. Run engine until oil temperature reaches 50°C -
80°C (122 - 176°F)
CAUTION:
●Leave valve of hydraulic pressure gauge fully open while
starting and running engine. If engine is started with
valve closed, hydraulic pressure in oil pump goes up.
This will relief pressure along with abnormal increase of
oil temperature.
●Care must be taken to keep hose clear of belt and other parts when engine is started.
3. Fully close hydraulic pressure gauge valve with engine at idle. Measure relief pressure.
4. After measurement, open valve slowly.
CAUTION:
Never keep valve closed for 15 seconds or longer.
●If relief pressure is outside specification, disassemble and service oil pump. Refer to PS-25, "Disas-
sembly and Assembly(QR20DE and QR25DE engine models)" .
5. After inspection, remove oil pressure gauge from hydraulic circuit. Add fluid. Be sure to bleed the system
completely. Refer to PS-5, "
Bleeding Hydraulic System"
Removal and Installation (QR20DE and QR25DE engine models)EGS000AG
REMOVAL

REMOVAL
1. Remove rear axle. Refer to RAX-6, "REMOVAL" .
NOTE:
In order to remove the rear drive shaft assembly, the rear axle is removed. At this time it is recommended
that front and rear parallel links on axle side be loosened (not removed). This will facilitate wheel align-
ment inspection and adjustment which are carried out later.
2. As shown in the figure, use a wheel wrench or similar tool to
remove drive shaft from final drive.
INSPECTION AFTER REMOVAL
●Move the joint in the up/down, left/right, and axial directions. Check for any rough movement or significant
looseness.
●Check boot for cracks or other damage, and also for grease leakage.
INSTALLATION
1. In order to prevent damage to final drive side oil seal, first fit a
protector onto oil seal before inserting drive shaft. Slide drive
shaft into slide joint and tap with a hammer to install securely.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EHS000MW
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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 harness connec-
tors.
Precaution for Seat Belt ServiceEHS000BE
CAUTION:
●Before removing the seat belt pre-tensioner assembly, turn the ignition switch off, disconnect
both battery cables and wait at least 3 minutes.
●Do not use electrical test equipment for seat belt pre-tensioner connector.
●After replacing or reinstalling seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-
sioner connector, check the system function. Refer to SRS-16, "
SRS Operation Check" .
●Do not use disassemble buckle or seat belt assembly.
●Replace anchor bolts if they are deformed or worn out.
●Never oil tongue and buckle.
●If any component of seat belt assembly is questionable, do not repair. Replace the whole seat belt
assembly.
●If webbing is cut, frayed, or damaged, replace seat belt assembly.
●When replacing seat belt assembly, use a genuine seat belt assembly.
AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies including retractors and attaching hardware after any collision.
NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the col-
lision was minor and the belts show no damage and continue to operate properly. Failure to do so
could result in serious personal injury in an accident. Seat belt assemblies not in use during a colli-
sion should also be replaced if either damage or improper operation is noted. Seat belt pre-tensioner
should be replaced even if the seat belts are not in use during a frontal collision in which the air bags
are deployed.
Replace any seat belt assembly (including anchor bolts) if:
●The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and
buckles show no damage and continue to operate properly).
●The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide, etc.)
●The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage
or distortion and repair as necessary before installing a new seat belt assembly.
●Anchor bolts are deformed or worn out.
●The seat belt pre-tensioner should be replaced even if the seat belts are not in use during the collision in
which the air bags are deployed.
