Maintenance of Lubricant Quantity in
Compressor
The lubricant used to lubricate 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 speci®ed 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)
LUBRICANT
Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
CHECKING AND ADJUSTING
Adjust the lubricant quantity according to the ¯owchart shown
below.
START
Can lubricant return operation be per-
formed?
+A/C system works properly.
+There is no evidence of a large amount of
lubricant leakage.
No
cYe s
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.
Should the compressor be replaced?
No Yes
b
jA(Go to next page.)
Is there any part to be replaced?
(Evaporator, condenser, liquid tank or in
case there is evidence of a large amount of
lubricant leakage.)
No
cYe s
After replacing any of the following major components, add the correct
amount of lubricant to the system.
Amount of lubricant to be added
*1: If compressor is replaced, addition of lubricant is included in the ¯ow
chart.
*2: If refrigerant leak is small, no addition of lubricant is needed.
Carry out the A/C performance test.b

SERVICE PROCEDURESMANUAL AND AUTO

+Pulley removal
Use any commercially available pulley puller and tool. Position
the center of it on the end of the tool, and remove the pulley
assembly.
For pressed pulleys
To prevent deformation of the pulley groove, the puller
claws should be hooked under the pulley (not into the
groove). For machine latched pulleys
Align the pulley puller groove with the pulley groove, and
then remove the pulley assembly.
+Remove the three ®eld coil ®xing screws and remove the ®eld
coil.
INSPECTION
Clutch disc:If the contact surface shows signs of damage due to
excessive heat, replace clutch disc and pulley.
Pulley:Check the appearance of the pulley assembly. Check the
contact surface of the pulley for any sign of excessive grooving due
to slippage. If any sign is found, replace both the pulley and clutch
disc. The contact surfaces of the pulley assembly should be
cleaned with a suitable solvent before reinstallation.
Coil:Check coil for loose connection or cracked insulation.
INSTALLATION
+Install the ®eld coil.
Be sure to align the coil's pin with the hole in the compres-
sor's front head.
+Install the pulley assembly using the installer and a hand press,
and then install the snap ring using snap ring pliers.
