INSTALLATION
Installation of the remaining components is in the reverse order of removal, while paying attention to the fol-
lowing:

When installing transmission to the engine, attach the bolts as shown.
NOTE:
*: No.2 bolt also secures air breather vent.
CAUTION:

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

Improper alignment caused by missing dowels may
cause vibration, oil leaks or breakage of drivetrain com-
ponents.

Align the positions of bolts for drive plate with those of the torque
converter, and temporarily tighten the bolts. Then tighten the
bolts with the specified torque.
CAUTION:

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

After converter is installed to drive plate, rotate crankshaft
several turns and check to be sure that transmission
rotates freely without binding.

Install crankshaft position sensor (POS).

After completing installation, check fluid leakage, fluid level, and
the positions of A/T. Refer to AT- 1 2 , "
Checking Automatic Transmission Fluid (ATF)" , AT- 2 2 7 , "Checking
of A/T Position" and AT- 2 2 7 , "Adjustment of A/T Position" .

Removal and InstallationEBS00RFH
WARNING:

Situate vehicle on a flat and solid surface.

Place chocks at front and back of rear wheels.

For engines not equipped with engine slingers, attach proper slingers and bolts described in
PARTS CATALOG.
CAUTION:

Always be careful to work safely, avoid forceful or uninstructed operations.

Do not start working until exhaust system and engine coolant are cooled sufficiently.

If items or work required are not covered by the engine section, refer to the applicable sections.

Always use the support point specified for lifting.

Use either 2-point lift type or separate type lift. If board-on type is used for unavoidable reasons,
support at the rear axle jacking point with transmission jack or similar tool before starting work, in
preparation for the backward shift of center of gravity.

For supporting points for lifting and jacking point at rear axle, refer to GI-41, "Garage Jack and
Safety Stand" .
REMOVAL
Preparation
1. Drain the engine coolant. Refer to CO-11, "DRAINING ENGINE COOLANT" .
2. Partially drain the A/T fluid. Refer to AT- 1 2 , "
Changing Automatic Transmission Fluid (ATF)" .
3. Release the fuel pressure. Refer to EC-80, "
FUEL PRESSURE RELEASE"

PRECAUTIONS
Revision: November 20092006 QX56
General PrecautionsEAS001F7

Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any flammable
materials. Special care should be taken when handling any flam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or other enclosed area, be sure to
properly ventilate the area before working with hazardous mate-
rials.
Do not smoke while working on the vehicle.

Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.

When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.

Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.

If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.

Battery posts, terminals and related accessories contain lead
and lead compounds. Wash hands after handling.

To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.

Dispose of or recycle drained oil or the solvent used for cleaning
parts in an appropriate manner.

Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.

Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.

Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.

Replace inner and outer races of tapered roller bearings and needle bearings as a set.

Arrange the disassembled parts in accordance with their assembled locations and sequence.

Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.

After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

Use only the fluids and lubricants specified in this manual.

PERIODIC MAINTENANCE
Revision: November 20092006 QX56
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace drive belts if da maged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, go to the FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “ *” are recommended by NISSAN for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are
required.
