COMPRESSOR(for 1WW) INSTALLATION

PROCEDURE

ADJUST AMOUNT OF COMPRESSOR OIL
1. 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 (Amount of oil to be drained)
  
  90 to 105 cc (3.0 to 3.6 fl. oz.)
  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.
  
  for HFC-134a(R134a):
  
  Be sure to use ND-OIL 8 for compressor oil.
  
  for HFO-1234yf(R1234yf):
  
  Be sure to use ND-OIL 12 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. 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. 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.
INSTALL COMPRESSOR ASSEMBLY WITH PULLEY
1. Text in Illustration
  
  *a Protrusion Height
  
  Using a plastic-faced hammer, tap in a new compressor pin.
  
  Standard protrusion height
  
  3.5 to 4.5 mm (0.138 to 0.177 in.)
2. Using an E8 "TORX" socket wrench, install the 2 stud bolts.
  
  Torque:
