Component Inspection
INSPECTION1. INSPECT MAGNETIC CLUTCH CLEARANCE
a. Set the dial indicator to the magnet clutch hub.
b. Connect the battery positive lead to terminal 3 of the magnet clutch connector and the negative lead to the earth wire. Turn the magnet clutch on and off and measure the clearance.
Standard clearance: 0.35 to 0.60 mm (0.014 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.
NOTE: Adjustment shall be performed with 3 or less magnet clutch washers.
c. Remove the compressor and magnetic clutch from the vise.
d. Install the bracket with the 2 bolts.
2. ADJUST COMPRESSOR OIL
a. When replacing the compressor and magnetic clutch with a 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.
Amount of oil:
(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 from the new compressor)
NOTE:
- 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-OIL 8 for compressor oil.
