COMPRESSOR(for 2KD-FTV) INSTALLATION

PROCEDURE

1. ADJUST COMPRESSOR OIL

   
   

   1. When replacing the compressor assembly with magnet 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 assembly with magnet clutch before installation.

      Standard
      w/o Thermostat, for Type A
      (Oil capacity inside the new compressor assembly with magnet clutch: 100 to 115 cc (3.38 to 3.89 fl.oz)) - (Remaining oil amount in the removed compressor assembly with magnet clutch) = (Oil amount to be removed from the new compressor)
      w/o Thermostat, for Type B
      (Oil capacity inside the new compressor assembly with magnet clutch: 100 to 115 cc (3.38 to 3.89 fl.oz)) - (Remaining oil amount in the removed compressor assembly with magnet clutch) = (Oil amount to be removed from the new compressor)
      w/ Thermostat
      (Oil capacity inside the new compressor assembly with magnet clutch: 80 to 95 cc (2.71 to 3.21 fl.oz)) - (Remaining oil amount in the removed compressor assembly with magnet clutch) = (Oil amount to be removed from the new compressor)

      *C	w/ Thermostat	-	-

      Note

      
      

      • If a new compressor assembly with magnet clutch 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 assembly with magnet clutch is too small, check the air conditioning system for oil leaks.

      • Be sure to use ND-OIL 8 or equivalent compressor oil. If any compressor oil other than ND-OIL 8 is used, compressor assembly with magnet clutch insulation performance may decrease, resulting in a leak of electric power.

2. INSTALL COMPRESSOR ASSEMBLY WITH MAGNET CLUTCH

   
   

   1. Tighten the 4 bolts in the order shown in the illustration to install the compressor assembly with magnet clutch.

      Torque:

      24.5 N*m  { 250 kgf*cm, 18 ft.*lbf }

3. CONNECT SUCTION HOSE SUB-ASSEMBLY

   
   

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

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

      Compressor Oil
      ND-OIL 8 or equivalent

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

      Note

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

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

      Torque:

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

4. CONNECT NO. 1 COOLER REFRIGERANT DISCHARGE HOSE

   
   

   1. Remove the vinyl tape from the No. 1 cooler refrigerant discharge hose and compressor assembly with magnet clutch.

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

      Compressor Oil
      ND-OIL 8 or equivalent

   3. Install the O-ring to the No. 1 cooler refrigerant discharge hose.

      Note

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

   4. Connect the No. 1 cooler refrigerant discharge hose to the compressor assembly with magnet clutch with the bolt.

      Torque:

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