*a Inside

(d) Connect the connector.

(e) Install the screw.

(f) Using a snap ring expander, install the magnet clutch rotor and a new snap ring with the chamfered side facing up. Text in Illustration *a Inside NOTICE: Do not damage the seal cover of the bearing when installing the snap ring.

(g) Install the compressor spacer and magnet clutch hub.

NOTICE:

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

(h) Using SST, hold the magnet clutch hub and install the bolt. SST: 09985-00260 Torque: 13.5 N·m {138 kgf·cm, 10 ft·lbf} NOTICE: Make sure that there is no foreign matter or oil on the compressor shaft, bolt, and clutch hub.

3. INSTALL PRESSURE RELIEF VALVE

(a) Apply sufficient compressor oil to a new O-ring and fitting surface of the pressure relief valve.

Compressor oil:

PSD1 or equivalent

(b) Install a new O-ring onto the pressure relief valve.

(c) Install the pressure relief valve.

Torque:

8.0 N·m {82 kgf·cm, 71 in·lbf}

4. INSPECT MAGNET CLUTCH CLEARANCE

(a) Secure the cooler compressor assembly in a vise between aluminum plates. Text in Illustration *a Component without harness connected (Magnet Clutch Assembly)

(b) Set the dial indicator to the magnet clutch hub.

(c) Connect the battery positive lead to terminal 1 (MG+) of the magnet clutch connector and the negative lead to the ground wire. Turn the magnet clutch on and off and measure the clearance.

Standard clearance:

0.30 to 0.60 mm (0.012 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:

0.2 mm (0.008 in.)

0.3 mm (0.012 in.)

0.5 mm (0.020 in.)

NOTICE:

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

(d) Remove the compressor and magnetic clutch from the vise.
