Tundra 2WD V6-4.0L (1GR-FE) (2005)
2. INSPECT MAGNET CLUTCH CLEARANCE
a. Set the dial indicator to the magnet clutch hub.
b. Connect the positive battery lead to terminal 1 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 (0.013 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.
NOTE: Adjustment should be performed with 3 or less magnet clutch washers.
3. INSPECT COMPRESSOR OIL
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.
Standard:
(Oil capacity inside the new compressor and magnetic clutch: 120 + 15 cc (4.0 + 0.5 fl. oz.) ) - (Remaining oil amount in the removed compressor
and magnetic clutch) = (Oil amount to be removed when replacing)
NOTE:
-
When checking the compressor oil level, observe the precautions in 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 excessive, 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 an oil leakage.
-
Be sure to use ND-OIL 8 or equivalent for compressor oil.
