COMPRESSOR INSTALLATION

PROCEDURE


  1. ADJUST COMPRESSOR OIL


    1. A005O2Y

      When replacing the compressor with motor assembly with a new one, gradually discharge the inert 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: 110 to 125 cc (3.8 to 4.2 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 leakage of electric power.

  2. INSTALL COMPRESSOR WITH MOTOR ASSEMBLY


    1. A005NN4N01

      Temporarily install the compressor with motor assembly with the 3 bolts.

    2. Tighten the 3 bolts and install the cooler compressor with motor assembly in the order shown in the illustration.

      Torque:
      25 N*m  { 255 kgf*cm, 18 ft.*lbf }
    3. A005MS2N01

      Connect the connector B.

    4. Remove the protective tape wrapped around connector A, and as shown in the illustration, connect connector A and lower the green lock to lock it securely.

      CAUTION:

      Make sure to wear insulating gloves.

      Note

      Make sure that the connector is connected securely.

  3. INSTALL SUCTION HOSE SUB-ASSEMBLY


    1. Remove the vinyl tape from the suction hose sub-assembly and compressor with motor assembly.

    2. Apply sufficient compressor oil to a new O-ring and fitting surface of the suction hose sub-assembly.

      Compressor Oil
      ND-OIL 11 or equivalent

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

      Note

      Keep the O-rings and O-ring fitting surfaces free of foreign matter.

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

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

  4. INSTALL DISCHARGE HOSE SUB-ASSEMBLY


    1. Remove the vinyl tape from the discharge hose sub-assembly and compressor with motor assembly.

    2. Apply sufficient compressor oil to a new O-ring and fitting surface of the discharge hose sub-assembly.

      Compressor Oil
      ND-OIL 11 or equivalent

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

      Note

      Keep the O-rings and O-ring fitting surfaces free of foreign matter.

    4. Connect 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 }
