NOTICE: Make sure that there is no foreign matter or oil on the compressor shaft, bolt, and clutch hub.

10. INSPECT MAGNETIC CLUTCH CLEARANCE

10. INSPECT MAGNETIC CLUTCH CLEARANCE

  1. Set the dial indicator to the magnet clutch hub.
  2. Connect the battery positive lead to the terminal 3 of magnet clutch connector and the negative lead to the earth wire. Turn on and off the magnet clutch and measure the clearance.

    Standard clearance:

    0.35 − 0.60 mm (0.014 − 0.024 in.)

If the measured value is out of the standard range, remove the magnet clutch hub and adjust it with magnet clutch washers.

NOTICE: Adjustment shall be performed with 3 or less magnet clutch washers.

12. INSPECT COMPRESSOR OIL

a. When replacing the compressor and magnetic clutch with new one, after gradually removing the refrigerant gas from the service valve, drain the following amount of oil from the new compressor and magnetic clutch before installation.

Standard: (Oil capacity inside new compressor and magnetic clutch: 120 + 15 cc (4.1 + 0.51 fl.oz.) ) − (Remaining oil amount in the removed compressor and magnetic clutch) = (Oil amount to be removed when replacing)

NOTICE:

  • When checking the compressor oil level, observe the precautions on the cooler removal/installation.

  • Because compressor oil remains in the pipes of the vehicle, if a new compressor and magnetic clutch is installed without removing some oil inside, the oil amount becomes too much, preventing heat exchange in the refrigerant cycle and causing refrigerant failure.

  • If the remaining oil in the removed compressor and magnetic clutch is too small in volume, check for oil leakage.

  • Be sure to use ND−OIL8 for compressor oil.
