COMPONENTS
REMOVAL
1. Remove drive shaft assembly. Refer to FA X - 8 , "FRONT DRIVE
SHAFT" .
2. Remove differential side oil seals using a flat-bladed screw-
driver.
CAUTION:
Be careful not to scratch transaxle case and converter
housing.

DIFFERENTIAL SIDE OIL SEAL

INSTALLATION
1. As shown below, use a drift to drive the differential side oil seal
into the case until it is flush. Refer to dimensions A.
Unit: mm (in)
NOTE:
The differential side oil seal pulling direction is used as the refer-
ence.
Drift to be used:
CAUTION:

When installing differential side oil seals, apply NISSAN CVT Fluid NS-2.

Do not reuse differential side oil seals.
2. Reinstall any part removed.
CAUTION:
If lubricant leak has occurred, after finishing work, check fluid level. Refer to CVT-13, "
Checking
CVT Fluid" .

TRANSAXLE ASSEMBLY

REMOVAL
CAUTION:
The transaxle assembly itself cannot be removed from the vehicle. Remove the transaxle assembly
and engine assembly together from the vehicle.
1. Disconnect the batter cable from the negative terminal.
2. Remove engine undercover.
3. Remove exhaust front tube with power tool. Refer to EX-2, "
Removal and Installation" .
4. Remove rear plate cover. Refer to EM-145, "
Removal and
Installation" .
5. Turn crankshaft, and remove the four tightening nuts for drive
plate and torque converter.
CAUTION:
The crankshaft should be rotated clockwise, viewed from
the front of the engine.
6. Remove the four bolts in the figure.
7. Remove transaxle assembly and engine assembly together
from the vehicle. Refer to EM-223, "
Removal and Installation" .
8. Remove drive shaft. Refer to FA X - 11 , "
Removal and Installation
(LH)" .
CAUTION:
Be sure to replace the differential side oil seal with new one
at the every removal of drive shaft. Refer to CVT-187,
"Removal and Installation" .
9. Remove rear gusset.
10. Remove CVT fluid level gauge.
11. Remove CVT fluid charging pipe.
12. Remove O-ring from CVT fluid charging pipe.
13. Disconnect harness connector and wire harness.

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-49, "
FUEL PRESSURE RELEASE" .
3. Disconnect fuel pump fuse to avoid fuel injection during mea-
surement.
4. Remove engine cover. Refer to EM-19, "
INTAKE MANIFOLD" .
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-31, "
IGNITION COIL" and EM-32,
"SPARK PLUG(PLATINUM-TIPPED TYPE)" .
6. Connect engine tachometer (not required in use of CONSULT-II).
7. Install compression tester with adapter onto spark plug hole.

Use compression gauge whose picking up end inserted to
spark plug hole is smaller than 20 mm (0.79 in) in diameter.
Otherwise, it may be caught by cylinder head during removal.
8. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge
pointer stabilizes, read the compression pressure and engine rpm. Perform these steps to check each cyl-
inder.
Compression pressure:
Unit: kPa (bar, kg/cm2 , psi) /rpm
CAUTION:
Always use a fully changed battery to obtain specified engine speed.
