COMPRESSOR AND MAGNETIC CLUTCH

DISASSEMBLY




1. REMOVE MAGNET CLUTCH ASSEMBLY
a. Clamp the cooler compressor in a vise.
b. Using SST, hold the magnet clutch hub.

SST 09960-10010 (09962-01000, 09963-00500)

c. Remove the bolt, magnet clutch hub and magnet clutch washer.

HINT: There is no set number of magnet clutch washers since they are used for adjusting.




d. Using a snap ring expander, remove the snap ring and the magnet clutch rotor.

NOTE: Do not damage the seal cover of the bearing when removing the snap ring.

e. Disconnect the connector.
f. Using a snap ring expander, remove the snap ring and magnet clutch stator.




2. REMOVE COOLER BRACKET
a. Remove the screw and the cooler bracket.

REASSEMBLY




1. INSTALL COOLER BRACKET
a. Install the cooler bracket with the screw.




2. INSTALL MAGNET CLUTCH ASSEMBLY

SST 09960-10010 (09962-01000, 09963-00500)

a. Install the magnet clutch stator with the parts shown in the illustration matched.




b. Using a snap ring expander, install a new snap ring with the chamfered side facing up.
c. Connect the connector.




d. Using SST, install the magnet clutch rotor and a new snap ring with the chamfered side facing up.

NOTE: Do not damage the seal cover of the bearing when installing the snap ring.

e. Install the compressor spacer and magnet clutch hub.

NOTE: Do not change the combination of the compressor spacer used before disassembly.




f. Using SST, hold the magnet clutch hub and install the bolt.

SST 09960-10010 (09962-01000, 09963-00500)
Torque: 18 N.m (184 kgf.cm, 13 ft.lbf)

NOTE: Make sure that there is no foreign matter or oil on the compressor shaft, bolt, and clutch hub.




3. INSPECT MAGNET CLUTCH CLEARANCE
a. Clamp the cooler compressor in a vise.
b. Set the dial indicator to the magnet clutch hub.
c. Connect the battery positive lead to terminal 3 (MG+) 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 (0.014 to 0.024 in.)

If the measured value is not within the standard clearance, remove the magnet clutch hub and adjust the clearance using compressor spacer to obtain the standard clearance.

Compressor spacer thickness:
0.1 mm (0.004 in.)
0.3 mm (0.012 in.)
0.5 mm (0.020 in.)

NOTE: Adjustment should be performed with 3 or less magnet clutch washers.
