the bolt.
Torque: 18 NVm (184 kgfVcm, 13 ftVlbf)
11. INSPECT MAGNETIC CLUTCH CLEARANCE
(a) Set the dial indicator to the magnet clutch hub.
(b) Connect the battery positive lead to the terminal 3 of 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:
0.35 - 0.60 mm (0.014 - 0.024 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.
(c) Remove the compressor and magnetic clutch from the
vise.
(d) Install the bolt and bracket.

13. INSPECT COMPRESSOR OIL
(a) When replacing the compressor and magnetic clutch with new one, after gradually removing the refrig-
erant gas from the service valve, drain the following amount of oil from the new compressor and mag-
netic clutch before installation.
Standard:
(Oil capacity inside new compressor and magnetic clutch: 120 + 15 cc (4.1 + 0.51 fl.oz.) ) - (Re-
maining oil amount in the removed compressor and magnetic clutch) = (Oil amount to be re-
moved when replacing)
NOTICE:
When checking the compressor oil level, observe the precautions on the cooler removal/instal-
lation.
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.
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-OIL8 for compressor oil.
14. TEMPORARY TIGHTEN COMPRESSOR AND
MAGNETIC CLUTCH
(a) Temporarily the compressor and magnetic clutch with the
3 bolts.
15. FULLY TIGHTEN COMPRESSOR AND MAGNETIC
CLUTCH

Torque: 25 NVm (250 kgfVcm, 18 ftVlbf)
(b) Install the cooler compressor bracket with the 2 bolts and
nut.
Torque:
25 NVm (250 kgfVcm, 18 ftVlbf) (Bolt (C))
25 NVm (250 kgfVcm, 18 ftVlbf) (Nut (D))
