COMPRESSOR(for 1WW, 2WW) INSTALLATION

PROCEDURE


  1. ADJUST AMOUNT OF COMPRESSOR OIL


    1. A004R8F

      When replacing the compressor assembly with a new one:

      Drain the following amount of compressor oil from the new compressor with pulley to be installed to adjust the amount of compressor oil.

      Standard
      (The amount of oil in a new compressor assembly with pulley: 90 to 105 cc (3.04 to 3.55 fl.oz.)) - (The amount of oil in the removed compressor assembly with pulley) = The amount of oil to be removed from the new compressor assembly with pulley.

      Note


      • Since compressor oil remains in the pipes of the vehicle, if a new compressor is installed without removing some oil from the compressor, the oil amount becomes excessive. Excessive oil prevents heat exchange in the refrigerant cycle and causes refrigeration system failure.

      • Be sure to use ND-OIL 8 or equivalent for compressor oil.


      1. Discharge the inert gas (helium) from the service valve.

      2. Remove the suction seal cap.

      3. Position the suction port downward and slightly shake the compressor to drain oil.*1

        Note

        Be careful not to allow compressor oil to adhere to the pulley.

    2. A004S62

      Position the pulley side downward and turn the pulley in the direction indicated by the arrow once every 2 seconds 10 times.*2

      Note

      Keep your face away from the compressor port because turning the pulley may cause gas or oil to spew out.

    3. A004U18

      Quickly position the pulley side upward and turn the pulley in the direction indicated by the arrow once.*3

    4. Repeat procedure *1.*4

    5. Repeat procedures *2 through *4 approximately 5 times to drain the standard amount of oil.

  2. INSTALL COMPRESSOR ASSEMBLY WITH PULLEY

      Tech Tips

      Tighten the bolts and nuts in the order shown in the illustration.

    4. Connect the connector and attach the harness clamp.

  3. CONNECT DISCHARGE HOSE SUB-ASSEMBLY


    1. Remove the attached vinyl tape from the hose and compressor.

    2. Apply sufficient compressor oil to a new O-ring and the fitting surface of the compressor assembly with pulley.

      Compressor oil
      ND-OIL 8 or equivalent

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

    4. Connect the discharge hose sub-assembly to the compressor assembly with pulley with the bolt.

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

  4. CONNECT SUCTION HOSE SUB-ASSEMBLY


    1. Remove the attached vinyl tape from the hose and compressor.

    2. Apply sufficient compressor oil to a new O-ring and the fitting surface of the compressor assembly with pulley.

      Compressor oil
      ND-OIL 8 or equivalent

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

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