COMPRESSOR INSTALLATION

PROCEDURE


  1. INSPECT COMPRESSOR OIL


    1. A01KSM9

      When replacing the compressor with motor assembly with a new one, gradually discharge the refrigerant gas from the service valve, and drain the following amount of oil from the new compressor with motor assembly before installation.

      Standard
      (Oil capacity inside the new compressor with motor assembly: 130 to 145 cc (4.4 to 4.9 fl.oz.)) - (Remaining oil amount in the removed compressor with motor assembly) = (Oil amount to be removed from the new compressor)

      Note


      • If a new compressor with motor assembly is installed without removing some oil, there will be too much oil in the system due to the oil remaining in the pipes of the vehicle. Excessive oil in the system prevents heat exchange in the refrigeration cycle and causes ineffective cooling.

      • If the amount of oil remaining in the old compressor with motor assembly is too small, check the air conditioning system for oil leaks.

      • Be sure to use ND-OIL 11 or equivalent compressor oil. If any compressor oil other than ND-OIL 11 is used, compressor with motor assembly insulation performance may decrease, resulting in a leak of electric power.

  2. INSTALL COMPRESSOR WITH MOTOR ASSEMBLY


    1. A01KTRKC01

      Install the compressor with motor assembly with the 3 bolts.

      Torque:
      25 N*m  { 255 kgf*cm, 18 ft.*lbf }

      Tech Tips

      Tighten the bolts in the order shown in the illustration.

    2. A01KRYBC01
      *a Green-colored Lock
      A01KSJJ Slide

      Connect the connector <B>.

    3. Connect the connector <A> and slide the green-colored lock as shown in the illustration to lock it securely.

      CAUTION:

      Make sure to wear insulating gloves.

      Note

      Make sure that the connector is connected securely.

  3. CONNECT SUCTION HOSE SUB-ASSEMBLY


    1. Remove the vinyl tape from the suction hose sub-assembly.

    2. Sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor with motor assembly.

      Compressor Oil
      ND-OIL 11 or equivalent

    3. Install the O-ring onto the suction hose sub-assembly.

    4. Install the suction hose sub-assembly to the compressor with motor assembly with the bolt.

      Torque:
      9.8 N*m  { 100 kgf*cm, 87 in.*lbf }

  4. CONNECT DISCHARGE HOSE SUB-ASSEMBLY


    1. Remove the vinyl tape from the discharge hose sub-assembly.

    2. Sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor with motor assembly.

      Compressor Oil
      ND-OIL 11 or equivalent

    3. Install the O-ring onto the discharge hose sub-assembly.

    4. Install the discharge hose sub-assembly to the compressor with motor assembly with the bolt.

      Torque:
      9.8 N*m  { 100 kgf*cm, 87 in.*lbf }
