Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure mayirritate eyes, nose and
throat. Remove HFC-134a (R-134a) from A/C system using certified serviceequipment meeting require-
ments of HFC-134a (R-134a) recycling equipment or HFC-134a (R-134a) recovery equipment. If acci-
dental system discharge occurs, ventilate work area before resuming service. Additional health and
safety information may be obtained from refrigerant and lubricant manufacturers.

Maintenance of Lubricant Quantity in
Compressor
NJHA0160The lubricant in the compressor circulates through the system with
the refrigerant. Add lubricant to compressor when replacing any
component or after a large gas leakage occurred. It is important to
maintain the specified amount.
If lubricant quantity is not maintained properly, the following mal-
functions may result:
Lack of lubricant: May lead to a seized compressor
Excessive lubricant: Inadequate cooling (thermal exchange
interference)
LUBRICANTNJHA0160S01Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
CHECKING AND ADJUSTINGNJHA0160S02Adjust the lubricant quantity according to the test group shown
below.
1 LUBRICANT RETURN OPERATION
Can lubricant return operation be performed?
A/C system works properly.
There is no evidence of a large amount of lubricant leakage.
YesorNo
Ye s G O T O 2 .
No GO TO 3.
2 PERFORM LUBRICANT RETURN OPERATION, PROCEEDING AS FOLLOWS
1. Start engine, and set the following conditions:
Test condition
Engine speed: Idling to 1,200 rpm
A/C switch: ON
Blower speed: Max. position
Temp. control: Optional [Set so that intake air temperature is 25 to 30°C (77 to 86°F).]
2. Perform lubricant return operation for about 10 minutes.
3. Stop engine.
CAUTION:
If excessive lubricant leakage is noted, do not perform the lubricant return operation.
GO TO 3.
3 CHECK COMPRESSOR
Should the compressor be replaced?
YesorNo
Yes GO TO HA-81.
No GO TO 4.

4 CHECK ANY PART
Is there any part to be replaced? (Evaporator, condenser, liquid tank or incase there is evidence of a large amount of
lubricant leakage.)
YesorNo
Yes GO TO HA-81.
No Carry out the A/C performance test.

— Small leak *2
*1: If compressor is replaced, addition of lubricant is included in the table.
*2: If refrigerant leak is small, no addition of lubricant is needed.
Lubricant Adjustment Procedure for Compressor
Replacement
NJHA0160S02021. Discharge refrigerant into the refrigerant recovery/recycling
equipment. Measure lubricant discharged into the recovery/
recycling equipment.
2. Drain the lubricant from the “old” (removed) compressor into a
graduated container and recover the amount of lubricant
drained.
3. Drain the lubricant from the “new” compressor into a separate,
clean container.
4. Measure an amount of new lubricant installed equal to amount
drained from “old” compressor. Add this lubricant to “new” com-
pressor through the suction port opening.
5. Measure an amount of new lubricant equal to the amount
recovered during discharging. Add this lubricant to “new” com-
pressor through the suction port opening.
6. If the liquid tank also needs to be replaced, add an additional
5m(0.2 Imp fl oz) of lubricant at this time.
Do not add this 5 m(0.2 Imp fl oz) of lubricant if only
replacing the compressor.

RHA124FA
Remove the clutch disc using the clutch disc puller.
Insert the holder’s three pins into the holes in the clutch disc.
Rotate the holder clockwise to hook it onto the plate. Then,
tighten the center bolt to remove the clutch disc.
After removing the clutch disc, remove the shims from either
the drive shaft or the clutch disc.
RHA138E
Remove the snap ring using external snap ring pliers.
RHA139E
Pulley removal
Position the center pulley puller on the end of the drive shaft,
and remove the pulley assembly using any commercially avail-
able pulley puller.
To prevent the pulley groove from being deformed, the
puller claws should be positioned onto the edge of the
pulley assembly.
