Adjust the spacer ASSY so that the gap between the pulley
and armature (armature gap) is within 0.5 to 0.8 mm (0.020
to 0.031 in).
(7)
Install the armature while aligning it with the groove.
Remove dirt and oil from the rotor contacting surface.
(8) Install the 8 mm nut and hub nut using CLUTCH
TIGHTENER (925770000), torque wrench and 13 mm
socket.
Tightening torque:
19 - 21 N·m (1.9 - 2.1 kg-m, 14 - 16 ft-Ib)

(1) Charge oil using measuring cylinder and plastic oiler.
L4-1558
Fig. 70
Measure 150 mQ (5.1 US fl oz, 5.3 Imp fl oz) of oil using a
measuring cylinder, and charge oil from the inlet port using a
plastic oiler. [If some oil is already charged in the cycle of the
cycle carrier, adjust the amount of new oil to be charged so
that the total amount will be 150 mQ (5.1 US fl oz, 5.3
Imp fl oz) in the cycle.]
(2) Run the compressor on the cycle carrier for checking
DV leakage, and also for checking compressor perform-
ance.
Before starting the operation, be sure to evacuate the refriger-
ant cycle to avoid air trapped inside.
(3) Charge refrigerant using INJECTOR NEEDLE
(926190000).
a. Charging pressure 98 to 147 kPa (1.0 to 1.6 kg/cm
l
,
14 to
21
psi).
b. Refer to "Charging Refrigerant" in manual.
TEST
NOISE TEST
Open the compressor outlet and inlet ports, and rotate the
armature. No abnormal noises nor irregular rotation must be
noted inside the compressor and magnet clutch.
COMPRESSION TEST
Close the compressor outlet or inlet port with a finger, and
rotate the armature, and check for normal compression or
suction.
