Lubrication Oil
Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
Maintenance of Oil Quantity in Compressor
The oil used to lubricate the compressor circulates through the
system with the refrigerant. Whenever any component of the sys-
tem is replaced or a large amount of gas leakage occurs, add oil
to the compressor to maintain the specified amount.
If oil quantity is not maintained properly, the following malfunctions
may result:
ILack of oil: May lead to a seized compressor
I Excessive oil: Inadequate cooling (thermal exchange impeded)
Checking and Adjusting
Adjust the oil quantity according to the flowchart shown below.
START
Can oil return operation be performed?
IA/C system works properly.
I There is no evidence of a large amount
of oil leakage.
No
EYe s
Perform oil return operation, proceeding as follows:
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 1. Start engine, and set the following conditions:
I 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 oil return operating for about 10 minutes.
3. Stop engine.
CAUTION:
If excessive oil leakage is noted, do not perform the oil return operation.
Should the compressor be replaced?
No Yes
qA(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 oil leakage.)
No
EYe s After replacing any of the following major components of the system, be sure
to add the correct amount of oil to the system.
Amount of oil to be added
*1: If compressor is replaced, addition of oil is included in the flow chart.
*2: If refrigerant leak is small, no addition of oil is needed. ªRatioº in this table indicates the ratio of added oil to the overall amount of oil needed in the
system.
Carry out the A/C performance test.F

qA
1. Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure oil discharged into the recovery/recyclingequipment.
2. Drain the oil from the ªoldº (removed) compressor into a graduated container, and record the amount of oil drained.
3. Drain the oil from the ªnewº compressor into a separate, clean container.
4. Measure an amount of the new oil equivalent to that drained from the ªoldº compressor, and add this oil to the ªnewº com- pressor through the drain plug or suction port opening.
5. Measure an amount of the ªnewº oil equivalent to that recovered during discharging, and add this oil to the ªnewº compressor through the drain plug or suction port opening.
6. If the liquid tank also needs to be replaced, add an additional 5 m (0.2 Imp fl oz) of oil at this time.
Do not add this 5 m (0.2 Imp fl oz) of oil if only replacing the compressor.

Compressor Clutch
REMOVAL
IWhen removing center bolt, hold clutch disc with clutch disc
wrench.
I Remove the drive plate using Tool.
Insert holder's three pins into the drive plate. Rotate the holder
clockwise to hook it onto the plate. Then, tighten the center bolt
to remove the drive plate.
After removing the drive plate, remove the shims from either the
drive shaft or the drive plate.
I Remove the snap ring using external snap ring pliers.

IPulley 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.
I Remove the three field coil fixing screws and remove the field
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
IInstall the field coil.
Be sure to align the coil's pin with the hole in the compres-
sor's front head.
I Install the pulley assembly using the installer and a hand press,
and then install the snap ring using snap ring pliers.

IInstall the drive plate on the drive shaft, together with the origi-
nal shim(s). Press the drive plate down by hand.
I Using the holder to prevent drive plate rotation, tighten the bolt
to 12 to 14 N ×m (1.2 to 1.4 kg-m, 9 to 10 ft-lb) torque.
After tightening the bolt, check that the pulley rotates
smoothly.
I Check clearance around the entire periphery of clutch disc.
Disc-to-pulley clearance: 0.3 - 0.6 mm (0.012 - 0.024 in)
If the specified clearance is not obtained, replace adjusting
shim and readjust.
BREAK-IN OPERATION
When replacing compressor clutch assembly, always conduct the
break-in operation. This is done by engaging and disengaging the
clutch about thirty times. Break-in operation raises the level of
transmitted torque.
