REGULATOR VALVE INSPECTIONNJLC00081. Visually inspect components for wear and damage.
2. Check oil pressure regulator valve sliding surface and valve
spring.
3. Coat regulator valve with engine oil.
Check that it falls smoothly into the valve hole by its own
weight.
If damaged, replace regulator valve set or front cover assem-
bly.

4. Check regulator valve to front cover clearance.
Clearance 6:
For Sedan
0.040 - 0.097 mm (0.0016 - 0.0038 in)
For Hatchback
0.052 - 0.088 mm (0.0020 - 0.0035 in)

Changing Engine OilNJLC0035WARNING:
+Be careful not to burn yourself, as the engine oil is hot.
+Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Stop engine and wait more than 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.
Oil specification and viscosity:

Drain plug:
: 29 - 39 N´m (3.0 - 4.0 kg-m, 22 - 29 ft-lb)

General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform the
checks and inspections themselves or they can have their NISSAN dealers do them for a nominal charge.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
Item Reference page
TiresCheck the pressure with a gauge periodically when at a service station,
including the spare, and adjust to the specified pressure if necessary. Check
carefully for damage, cuts or excessive wear.Ð
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. Ð
Doors and engine
hoodCheck that all doors, the engine hood, the trunk lid and back door operate
properly. Also ensure that all latches lock securely. Lubricate if necessary.
Make sure that the secondary latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other corrosive materials, check for
lubrication frequently.BT-7
BT-16
Tire rotationTires should be rotated every 10,000 km (6,000 miles). SU-7
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.
Item Reference page
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps,
and other lamps are all operating properly and installed securely. Also check
headlamp aim.Ð
Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating prop-
erly.Ð
Steering wheelCheck that it has the specified play.
Check for changes in the steering conditions, such as excessive free play,
hard steering or strange noises.
Free play: Less than 35 mm (1.38 in)Ð
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters
and retractors) operate properly and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying, wear or damage.RS-4
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the engine oil or refuel.
Item Reference page
Windshield washer
fluidCheck that there is adequate fluid in the tank. Ð
Engine coolant levelCheck the coolant level when the engine is cold. LC-19, LC-45
Engine oil levelCheck the level after parking the vehicle (on level ground) and turning off
the engine.LC-8, LC-31
Brake and clutch
fluid levelsMake sure that the brake and clutch fluid levels are between the ªMAXº and
ªMINº lines on the reservoir.BR-8
BatteryCheck the fluid level in each cell. It should be between the ªMAXº and ªMINº
lines.Ð

b. Install outer race onto differential side bearing on final gear
side. Holding lightly the outer race horizontally by hand, rotate
final gear five times or more (for smooth movement of bearing
roller).
c. Using dial gauge and scale as shown in the figure, measure
dimension ªN2º between differential side bearing outer race
and transaxle case end face.
SMT738DB
4. Install selected shim and bearing outer race.

5. Measure turning torque of final drive assembly.
Turning torque of final drive assembly
(New bearing):
2.9 - 6.9 N´m (30 - 70 kg-cm, 26 - 61 in-lb)
+When old bearing is used again, turning torque will be
slightly less than the above.
+Make sure torque is close to the specified range.
+Changes in turning torque of final drive assembly per
revolution should be within 1.0 N´m (10 kg-cm, 8.7 in-lb)
without binding.
SMT743D
6. Calculate dimension ªOº (thickness of adjusting shim) using
the following procedure to satisfy specification of end play for
input shaft rear bearing.
End play: 0 - 0.06 mm (0 - 0.0024 in)
Dimension ªOº = (O1 ± O2) + End play
O: Thickness of adjusting shim
O1: Distance between transaxle case end face and
mounting face of adjusting shim
O2: Distance between clutch housing case end
face and end face of input shaft rear bearing
Input shaft rear bearing adjusting shims:
