INSPECT MAGNETIC CLUTCH CLEARANCE
(a)
Set the dial indicator to the magnet clutch hub.
(b)
Connect the battery positive lead to terminal 1 of the mag-
net clutch connector and the negative lead to the earth
wire. Turn on and off the magnet clutch and measure the
clearance.
Standard clearance:
0.20 to 0.45 mm (0.008 to 0.018 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.
10. ADJUST COMPRESSOR OIL
(a)
When replacing the compressor and magnetic clutch with a new one, after gradually removing the re-
frigerant 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: 60
10 cc (2.0
0.3 fl. oz.) ) -- (Re-
maining oil amount in the removed compressor and magnetic clutch) = (Oil amount to be re-
moved when replacing)
NOTICE:
S
When checking the compressor oil level, observe the precautions on the cooler removal/instal-
lation.
S
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, pre-
venting heat exchange in the refrigerant cycle and causing refrigerant failure.
S
If the remaining oil in the removed compressor and magnetic clutch is too small in volume,
check for oil leakage.
S
Be sure to use ND--OIL8 or equivalent for compressor oil.
