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 R for DKV-11G compres-
sor
Part number: KLH00-PAGR0
Name: Nissan A/C System Oil Type S for CSV613 compressor
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©GO TO 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 or AUTO switch: ON
Blower speed: Max. position
Temp. control: Optional [Set so that intake air temperature is 25 to 30ÉC (77 to 86ÉF).]
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.

3 CHECK COMPRESSOR
Should the compressor be replaced?
YesorNo
Ye s©GO TO HA-82.
No©GO TO 4.

INSPECTIONNJHA0213Clutch DiscNJHA0213S01If the contact surface shows signs of damage due to excessive
heat, replace clutch disc and pulley.
PulleyNJHA0213S02Check the appearance of the pulley assembly. If the contact sur-
face of pulley shows signs of excessive grooving, replace clutch
disc and pulley. The contact surfaces of the pulley assembly should
be cleaned with a suitable solvent before reinstallation.
CoilNJHA0213S03Check coil for loose connection or cracked insulation.
RHA142E
INSTALLATIONNJHA0214+Install the field coil.
Be sure to align the coil's pin with the hole in the com-
pressor's front head.
+Install the field coil harness clip using a screwdriver.
