DISASSEMBLY
NOTE:
Explained here is how to disassemble with engine stand supporting transmission surface. When using differ-
ent type of engine stand, note with difference in steps and etc.
1. Remove engine assembly from vehicle, and separate front suspension member, transmission and front
final drive from engine. Refer to EM-236, "
ENGINE ASSEMBLY" .
2. Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use widely use engine holding the surface, to which trans-
mission is installed.
a. Remove drive plate.

Holding ring gear with ring gear stopper (SST).

Loosen mounting bolts diagonally order.
CAUTION:

Do not disassemble drive plate.

Do not place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
b. Remove engine rear plate.
3. Lift engine with hoist to install it onto widely use engine stand.
CAUTION:
Use engine stand that has a load capacity [approximately 240kg (529 lb) or more] large enough for
supporting the engine weight.

If the load capacity of stand is not adequate, remove the following parts beforehand to reduce the
potential risk of overturning stand.
–Intake manifolds (upper and lower); Refer to EM-174, "INTAKE MANIFOLD" .
–Exhaust manifold; Refer to EM-178, "EXHAUST MANIFOLD AND THREE WAY CATALYST" .
–Fuel tube and fuel injector assembly; Refer to EM-188, "FUEL INJECTOR AND FUEL TUBE" .
–A/C compressor; Refer to ATC-139, "Components" .
–Ignition coil; Refer to EM-185, "IGNITION COIL" .
13. Piston pin 14. Connecting rod bearing 15. Connecting rod bearing cap
16. Block heater protector 17. Connector cap 18. Cylinder block heater
19. Gasket 20. Main bearing cap 21. Thrust bearing

10. Remove piston rings from piston.

Before removing the piston rings, check the piston ring side
clearance. Refer to EM-257, "
PISTON RING SIDE CLEAR-
ANCE" .

Use piston ring expander (commercial service tool).
CAUTION:

When removing piston rings, be careful not to damage
piston.

Be careful not to damage piston rings by expanding them
excessively.
11. Remove piston from connecting rod as follows:
a. Using snap ring pliers, remove the snap ring.
b. Heat piston to 60 to 70°C (140 to 158°F) with industrial use drier
or equivalent.
c. Push out piston pin with stick of outer diameter approximately 20
mm (0.8 in).
12. Remove rear oil seal retainer from cylinder block.

Insert flat-blade screwdriver or similar tool between rear end of crankshaft counter weight and rear oil
seal retainer, and separate liquid gasket to remove.
CAUTION:
Be careful not to damage the mating surface.
13. Using flat-blade screwdriver or similar tool, and lever off rear oil seal from rear oil seal retainer.
14. Remove main bearing cap as follows:

PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectAAS000OH
NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.

Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
General PrecautionsAAS000EY

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 inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
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.

HOW TO USE THIS MANUAL
Revision: 2004 November 2004 FX35/FX45
Detectable Lines and Non-Detectable Lines
In some wiring diagrams, two kinds of lines, representing wires, with different weight are used.

A line with regular weight (wider line) represents a “detectable
line for DTC (Diagnostic Trouble Code)”. A “detectable line for
DTC” is a circuit in which ECM can detect its malfunctions with
the on board diagnostic system.

A line with less weight (thinner line) represents a “non-detect-
able line for DTC”. A “non-detectable line for DTC” is a circuit in
which ECM cannot detect its malfunctions with the on board
diagnostic system.

Aiming AdjustmentAKS007CT
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.

Keep all tires inflated to correct pressure.

Place vehicle on level ground.

See that vehicle is unloaded (except for full levels of coolant, engine oil and fuel, and spare tire, jack, and
tools). Have the driver or equivalent weight placed in driver seat.
Adjust aiming in the vertical direction by turning the adjusting screw.
1. Set the distance between the screen and the center of the fog
lamp lens as shown at left.
2. Turn front fog lamps ON.
3. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is 100 mm (4 in) below the height of
the fog lamp centers as shown at left.

When performing adjustment, if necessary, cover the head-
lamps and opposite fog lamp.

INSPECTION AFTER DISASSEMBLY
Oil Pump Clearance

Measure clearance with feeler gauge.
Clearance between oil pump outer rotor and oil pump body
(position “1”)
Tip clearance between oil pump inner rotor and oil pump outer
rotor (position “2”)

Measure clearance with feeler gauge and straightedge.
Side clearance between oil pump inner rotor and oil pump body
(position “3”)
Side clearance between oil pump outer rotor and oil pump body
(position “4”)
Calculate the clearance between oil pump inner rotor and oil pump
body as follows.

Measure the inner diameter of oil pump body with inside
micrometer (Position “5”)

Measure the outer diameter of protruded portion of oil pump
inner rotor (Position “6”)

(Clearance) = (Inner diameter of oil pump body) – (Outer diame-
ter of oil pump inner rotor)
Regulator Valve Clearance
(Clearance) = (Regulator valve hole diameter) – (Outer diameter of
regulator valve)
CAUTION:

Coat regulator valve with new engine oil.

Make sure it falls smoothly into the regulator valve hole by
its own weight.Standard : 0.114 - 0.260 mm (0.0045 - 0.0102 in)
