NISSAN PATROL 2006 Service Manual

3. Move probe along component approximately 25 to 50 mm (1 to
2 in)/sec.
CHECKING PROCEDURE
To prevent inaccurate or false readings, make sure there is no
refrigerant vapor or tobacco smoke in the vicinity of the
vehicle. Perform the leak test in calm area (low air/wind move-
ment) so that the leaking refrigerant is not dispersed.
1. Turn engine off.
2. Connect a suitable A/C manifold gauge set to the A/C service
ports.
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.452
bar, 3.52 kg/cm
2, 50 psi) above 16ÉC (61ÉF). If less than
speci®cation, evacuate and recharge the system with the speci-
®ed amount of refrigerant.
NOTE: At temperatures below 16ÉC (61ÉF), leaks may not be
detected since the system may not reach 345 kPa
(3.452 bar, 3.52 kg/cm
2, 50 psi).
4. Conduct the leak test from the high side to the low side at points
in alphabetical order (j
a,jb......). Refer to HA-117.
Perform a leak check for the following areas carefully. Clean the
component to be checked and move the leak detector probe
completely around the connection/component.
+Compressor
Check the ®tting of high and low pressure hoses, relief valve
and shaft seal.
+Liquid tank
Check the pressure switch, tube ®tting, weld seams and the
fusible plug mounts.
+Service valves
Check all around the service valves. Ensure service valve caps
are secured on the service valves (to prevent leaks).
NOTE: After removing A/C manifold gauge set from service
valves, wipe any residue from valves to prevent any
false readings by leak detector.
+Cooling unit (Evaporator)
Turn blower fan on ``High'' for at least 15 seconds to dissipate
any refrigerant trace in the cooling unit. Insert the leak detector
probe into the drain hose immediately after stopping the
engine. (Keep the probe inserted for at least ten seconds.)
5. If a leak detector detects a leak, verify at least once by blowing
compressed air into area of suspected leak, then repeat check.
6. Do not stop when one leak is found. Continue to check for
additional leaks at all system components.
7. Start engine.
8. Set the heater A/C control as follows:
a. A/C switch ON
b. Face mode
c. Recirculation switch ON
d. Max cold temperature
e. Fan speed high

9. Run engine at 1,500 rpm for at least 2 minutes.
10. Turn engine off and perform leak check again following steps 4
through 6 above.
Refrigerant leaks should be checked immediately after stop-
ping the engine. Begin with the leak detector on the high pres-
sure line. The pressure in the high pressure line will gradually
drop after refrigerant circulation stops and pressure in the low
pressure line will gradually rise, as shown in the graph. Leaks
are more easily detected when pressure is high.
11. Discharge A/C system using approved refrigerant recovery
equipment. Repair the leaking ®tting or component as neces-
sary.
12. Evacuate and recharge A/C system and perform the leak test
to con®rm no refrigerant leaks.
13. Conduct A/C performance test to ensure system works prop-
erly.

REMOVAL
+When removing center bolt, hold clutch disc with clutch disc
wrench.
+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.
+Remove the snap ring using external snap ring pliers.

+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.

+Install the drive plate on the drive shaft, together with the origi-
nal shim(s). Press the drive plate down by hand.
+Using the holder to prevent drive plate rotation, tighten the bolt
to 12 to 14 Nzm (1.2 to 1.4 kg-m, 9 to 10 ft-lb) torque.
After tightening the bolt, check that the pulley rotates
smoothly.
+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 speci®ed 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.
