REAR FINAL DRIVE ASSEMBLY

13. Apply a continuos bead of sealant around the carrier case mat-
ing surface on the rear cover as shown in the figure. Overlap
both ends of the bead for at least 3 mm (0.12 in).
CAUTION:
Remove old sealant on the mounting surface, then remove
any moisture, oil, and foreign material on the application
and mounting surfaces.
14. Fit the suitable drifts to the right and left side bearing adjusting
shims individually. Compress differential case assembly and
side bearing to install the rear cover.
CAUTION:

The drift shall be placed on the center of the adjusting
shims.

The pressure shall be as low as possible to install the
rear cover. The maximum pressure shall be 10 kN (1 ton,
1.1 US ton, 1.0 Imp ton)

If the rear cover is forced in by tapping, the rear cover
may be damaged by the adjusting shims. Avoid tapping.
15. Tighten rear cover mounting bolts to the specified torque. Refer to RFD-16, "
Components" .
16. Using both drift, drive the oil seal until it becomes flush with the
case end.
CAUTION:

Do not reuse oil seals.

Apply multi-purpose grease onto the oil seal lips, and dif-
ferential oil onto the circumference of the oil seal.
17. Check overall preload torque. Refer to RFD-17, "
TOTAL PRE-
LOAD" .
Installation of Electric Controlled Coupling Assembly
1. Using the drift below, install the coupling front bearing to the
electric controlled coupling.
CAUTION:
At disassembly, be sure to install shim between electric
controlled coupling and bearing. Chamfering side of shim
should be coupled to install.
2. Assemble the electric controlled coupling assembly to the drive pinion gear.

General Refrigerant PrecautionsEJS000T2
WARNING:

Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.

Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.

Do not store or heat refrigerant containers above 52°C (125°F).

Do not heat a refrigerant container with an open flame; if container warming is required, place the
bottom of the container in a warm pail of water.

Do not intentionally drop, puncture, or incinerate refrigerant containers.

Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.

Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.

Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condi-
tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause
injury or property damage. Additional health and safety information may be obtained from refriger-
ant manufacturers.
Lubricant PrecautionsEJS0027Y

Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components.
If lubricant other than that specified is used, compressor malfunction is likely to occur.

The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The following
handling precautions must be observed:

When removing refrigerant components from a vehicle, immediately cap (seal) the component to minimize
the entry of moisture from the atmosphere.

When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just before con-
necting the components. Connect all refrigerant loop components as quickly as possible to minimize the
entry of moisture into system.

Only use the specified lubricant from a sealed container. Immediately reseal containers of lubricant. With-
out proper sealing, lubricant will become moisture saturated and should not be used.

Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If acciden-
tal system discharge occurs, ventilate work area before resuming service. Additional health and safety
information may be obtained from refrigerant and lubricant manufacturers.

Do not allow lubricant (Nissan A/C System Oil Type S or R) to come in contact with styrofoam parts. Dam-
age may result.
Precautions for Refrigerant ConnectionEJS000T4
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.

Expansion valve to cooling unit

Refrigerant pressure sensor to liquid tank

CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.

When the compressor is removed, store it in the same position as it is when mounted on the car.
Malfunction to do so will cause lubricant to enter the low-pressure chamber.

When connecting tubes, always use a torque wrench and a back-up wrench.

After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.

When installing an air conditioner in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for
connection.

Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.

Thoroughly remove moisture from the refrigeration system before charging the refrigerant.

Always replace used O-rings.

When connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.

O-ring must be closely attached to dented portion of tube.

When replacing the O-ring, be careful not to damage O-ring and tube.

Connect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.

After connecting line, conduct leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then
tighten connections of seal seat to the specified torque.With gasoline engine

REFRIGERATION SYSTEM

REFRIGERATION SYSTEMPFP:KA990
Refrigerant CycleEJS000TD
REFRIGERANT FLOW
The refrigerant flows in the standard pattern, that is, through the compressor, the condenser with liquid tank,
through the evaporator, and back to the compressor. The refrigerant evaporation through the evaporator coil is
controlled by an externally equalized expansion valve, located inside the evaporator case.
FREEZE PROTECTION (WITH GASOLINE ENGINE: CWV-615M COMPRESSOR)
Under usual operating conditions, when the A/C is switched on, the compressor runs continuously, and the
evaporator pressure, and therefore, temperature is controlled by the V-6 variable displacement compressor to
prevent freeze up.
Refrigerant System ProtectionEJS000TE
REFRIGERANT PRESSURE SENSOR (WITH GASOLINE ENGINE: CWV-615M COMPRESSOR)
The refrigerant system is protected against excessively high- or low-pressures by the refrigerant pressure sen-
sor, located on the liquid tank. If the system pressure rises above, or falls below the specifications, the refriger-
ant pressure sensor detects the pressure inside the refrigerant line and sends the voltage signal to the ECM.
ECM makes the A/C relay go OFF and stops the compressor when pressure on the high-pressure side
detected by refrigerant pressure sensor is over about 2,746 kPa (27.46 bar, 28 kg/cm
2 , 398 psi), or below
about 134 kPa (1.34 bar, 1.4 kg/cm
2 , 20 psi).
DUAL-PRESSURE SWITCH (WITH DIESEL ENGINE: DKV-11G COMPRESSOR)
The refrigerant system is protected against excessively high- or low-pressures by the dual-pressure switch,
located on the liquid tank. If the system pressure rises above or falls below the specifications, the dual-pres-
sure switch opens to interrupt the compressor operation.
PRESSURE RELIEF VALVE (WITH GASOLINE ENGINE: CWV-615M COMPRESSOR)
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.
When the pressure of refrigerant in the system increases to an unusual level [more than 3,727 kPa (37.27 bar,
38 kg/cm
2 , 540 psi)], the release port on the pressure relief valve automatically opens and releases refriger-
ant into the atmosphere.
