Disassembly and AssemblyNBS003IR
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.

PRECAUTIONS
Revision: 2006 December 2006 FX35/FX45
Precautions for Procedures without Cowl Top CoverNAS0005Z
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
General PrecautionsNAS00060

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.

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.

For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
1. Keep all tires inflated to correct pressures.
2. Place vehicle on level ground.
3. Set that there is no-load in vehicle other than the driver (or equivalent weight placed in driver's position). Coolant, engine oil filled up to correct level and full fuel tank.

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 adjusting screw.
1. Set the distance between the screen and the center of front 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 (3.94 in) below the height of
front fog lamp centers as shown at left.

When performing adjustment, if necessary, cover headlamps
and opposite front fog lamp.

Regulator Valve Clearance
(Clearance) = (Valve hole diameter) – (Regulator valve outer diame-
ter)

If the calculated value is out of the standard, replace oil pump
assembly.
CAUTION:

Coat regulator valve with engine oil.

Make sure that it falls smoothly into valve hole by its own
weight.
ASSEMBLY
Note the following, and assemble in the reverse order of disassembly.

OIL PUMP BODY INNER DIAMETER
–Measure the inner diameter of oil pump body with inside
micrometer. (Position 6)
OIL PUMP INNER DIAMETER TO OIL PUMP BODY CLEARANCE
–(Clearance) = (Oil pump body inner diameter) – (Oil pump inner rotor outer diameter)

If the measured/calculated values are out of the standard, replace oil pump assembly.
Regulator Valve Clearance
(Clearance) = D1 (Valve hole diameter) – D2 (Regulator valve outer
diameter of valve)

If the calculated value is out of the standard, replace oil pump
assembly.
CAUTION:

Coat regulator valve with engine oil.

Make sure that it falls smoothly into regulator valve hole by
its own weight.
ASSEMBLY
Note the following, and assemble in the reverse order of disassembly.

Install oil pump inner rotor and oil pump outer rotor with the
punched marks on the oil pump cover side.
