and, using a brass bar and hammer, tap in the left
and right rear drive shafts.
NOTICE:
• Face the cutout section of the snap ring
downward.
• Do not damage the oil seal during the
insertion.
• Do not strike the tip of the outboard joint with
the hammer.
HINT:
Determine whether or not the rear drive shaft is
completely tapped in by checking for changes in
sound or the reaction force of the brass bar.

AIR CONDITIONING – COMPRESSOR AND PULLEY (for 2AZ-FE)AC–217
AC
INSTALLATION
1. ADJUST ADJUST COMPRESSOR OIL
(a) When replacing the compressor and magnetic
clutch with a new one, gradually discharge the
refrigerant gas from the service valve, and drain the
following amount of oil from the new compressor
and magnetic clutch before installation.
Standard:
(Oil capacity inside the new compressor and
magnetic clutch: 130 + 15 cc (4.6 + 0.51 fl.oz.) )
-(Remaining oil amount in the removed
compressor and magnetic clutch) = (Oil
amount to be removed from the new
compressor when replacing)
NOTICE:
• When checking the compressor oil level,
observe the precautions on the cooler
removal/installation.
• If a new compressor and magnetic clutch is
installed without removing some oil
remaining in the pipes of the vehicle, the oil
amount will be too large. This prevents heat
exchange in the refrigerant cycle and causes
refrigerant failure.
• If the volume of oil remaining in the removed
compressor and magnetic clutch is too small,
check for oil leakage.
• Be sure to use ND-OIL 8 or equivalent for
compressor oil.
2. INSTALL COOLER COMPRESSOR ASSEMBLY
(a) w/o Stud Bolt:
Install the cooler compressor with the 4 bolts.
Torque: 24.5 N*m (250 kgf*cm, 18 ft.*lbf)
NOTICE:
Tighten the bolts in the order shown in the
illustration to install the cooler compressor.
(b) w/ Stud Bolt:
Install the cooler compressor with the 3 bolts and
nut.
Torque: 24.5 N*m (250 kgf*cm, 18 ft.*lbf)
NOTICE:
Tighten the bolts in the order shown in the
illustration to install the cooler compressor.
(c) Connect the connector.
