AIR CONDITIONING

COMPRESSOR AND MAGNETIC CLUTCH (1GR-FE)

INSPECT MAGNET CLUTCH CLEARANCE

Set the dial indicator to the magnet clutch hub.

Connect the positive battery lead to terminal 1 of the mag-

net clutch connector and the negative lead to the earth

wire. Turn the magnet clutch on and off and measure the

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 wash-

Adjustment should be performed with 3 or less magnet

clutch washers.

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.

(Oil capacity inside the new compressor and magnet-

ic 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)

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 ex-

change in the refrigerant cycle and causing refriger-

ant 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
