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

9. INSPECT MAGNETIC CLUTCH CLEARANCE

INSPECT MAGNETIC CLUTCH CLEARANCE


(a) Set the dial gage to the magnet clutch hub.

(b) Connect the positive battery lead to terminal 3 of the 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 to 0.60 mm (0.013 to 0.023 in.)

If the measured value is not within 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.

(c) Remove the compressor and magnetic clutch from the vise.

INSPECT MAGNETIC CLUTCH CLEARANCE


(d) Install bracket with the bolt.

10. 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 cooler compressor assy: 120 + 15 cc (4.06 + 0.5 fl.oz.)) - (Remaining oil amount in the removed cooler compressor assy) = (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 cooler compressor assy 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 cooler compressor assy is too small in volume, check for oil leakage.
  • Be sure to use ND-OIL8 for compressor oil.

11. TEMPORARILY TIGHTEN COMPRESSOR AND MAGNETIC CLUTCH

TEMPORARILY TIGHTEN COMPRESSOR AND MAGNETIC CLUTCH


(a) Install the compressor and magnetic clutch with the stud bolt, 3 bolts and nut.
