CVT-208
TRANSAXLE ASSEMBLY
Revision: June 20062007 Versa
4. Remove the four drive plate to torque converter nuts.
NOTE:
Rotate the crankshaft clockwise as viewed from front of engine
for access to drive plate to torque converter nuts.
5. Put matching marks on the drive plate and torque converter alignment stud.
CAUTION:
For matching marks, use paint. Never damage the drive plate or torque converter.
6. Remove the transaxle to engine and engine to transaxle bolts.
7. Separate the transaxle from the engine.
8. If necessary, remove the following from the transaxle:

CVT fluid charging pipe

Engine mounting bracket (LH)

Fluid cooler tubes

Air breather hose

Any necessary brackets
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:

When replacing an engine or transmission you must make sure any dowels are installed correctly
during re-assembly.

Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.

Do not reuse O-rings and copper washers.

When turning crankshaft, turn it clockwise as viewed from the front of the engine.

When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be
sure to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-37, "
TIMING
CHAIN" .

After converter is installed to drive plate, rotate crankshaft several turns to check that transaxle
rotates freely without binding.

When installing the torque converter to the transaxle measure
distance A.

BASIC SERVICE PROCEDURE
2007 Versa

Do not twist or kink fuel hose because it is plastic hose.
4. Connect fuel hose for fuel pressure check (1) to fuel tube
(engine side) with clamp (2) as shown in the figure.

No.2 spool (5)

Wipe off oil or dirt from hose insertion part using cloth moist-
ened with gasoline.

Apply proper amount of gasoline between top of the fuel tube
(3) and No.1 spool (4).

Insert fuel hose for fuel pressure check until it touches the
No.1 spool on fuel tube.

Use NISSAN genuine hose clamp (part number: 16439
N4710 or 16439 40U00).

When reconnecting fuel line, always use new clamps.

Use a torque driver to tighten clamps.

Install hose clamp to the position within 1 - 2 mm (0.04 - 0.08 in).

Make sure that clamp screw does not contact adjacent parts.
5. Connect fuel tube adapter to quick connector.

A: Fuel pressure gauge

B: Fuel hose for fuel pressure check
6. After connecting fuel hose for fuel pressure check, pull the hose
with a force of approximately 98 N (10 kg, 22 lb) to confirm fuel
tube does not come off.
7. Turn ignition switch ON and check for fuel leakage.
8. Start engine and check for fuel leakage.
9. Read the indication of fuel pressure gauge.

Do not perform fuel pressure check with system operating.
Fuel pressure gauge may indicate false readings.

During fuel pressure check, confirm for fuel leakage from fuel connection every 3 minutes.
10. If result is unsatisfactory, go to next step.
11. Check the following.

Fuel hoses and fuel tubes for clogging

Fuel filter for clogging

Fuel pump

Fuel pressure regulator for clogging
If OK, replace fuel pressure regulator.
If NG, repair or replace.
12. Check the following.

Fuel hoses and fuel tubes for clogging

Fuel filter for clogging

Fuel pump

Fuel pressure regulator for clogging
If OK, replace fuel pressure regulator.
If NG, repair or replace.
13. Before disconnecting Fuel Pressure Gauge and Fuel Pressure Adapter J-44321-6, release fuel pressure
to zero. Refer to EC-81, "
FUEL PRESSURE RELEASE" . Tightening torque: 1 - 1.5 N·m (0.1 - 0.15 kg-m, 9 - 13 in-lb)
At idling: Approximately 350 kPa (3.5 bar, 3.57 kg/cm
2 , 51 psi)
