7.  Assemble in the reverse order of disassembly.

8.  Adjust the magnetic clutch clearance. (See MAGNETIC CLUTCH ADJUSTMENT [MZR 1.6].)

Bolt Removal/Installation Note

1.  When removing or installing the bolt, lock the A/C compressor pulley against rotation using the following procedure.

Caution

•  When connecting the positive battery cable to the magnetic clutch connector, use a cable with a female terminal of the correct size. Otherwise, load will be applied to the terminal, resulting in deformation or damage, and poor contact. In addition, the positive battery cable could disconnect from the connector resulting in a short circuit.

(1)  Apply battery positive voltage to the magnetic clutch terminal and connect the A/C compressor body to the ground.

(2)  Wrap the drive belt, which is no longer of use, tightly around the A/C compressor pulley.

(3)  Hold the drive belt in place with pliers.

(4)  Remove/installation the bolt.

Tightening torque

10—15 N·m {102 —152 kgf·cm, 89 — 132 in·lbf}

2.  When installing a new A/C compressor body, replace the recommended bolt.

Snap Ring Removal/Installation Note

1.  Remove/install the snap ring using a snap ring pliers.

A/C Compressor Pulley Removal Note

Note

•  It may be difficult to remove the A/C compressor pulley due to the differences in the inner diameter tolerance. If the A/C compressor pulley cannot be removed even after pulling it, remove the pulley using the following procedure.

1.  Remove the A/C compressor pulley using the SSTs (49 0839 425C, 49 U027 001).

Caution

•  Be careful that the SST (49 0839 425C) tabs do not hang over the stator.

Note

•  Place on the tape to prevent damage.

A/C Compressor Pulley Installation Note

1.  Install the inner wheel of the pulley using SST (49 D034 202) to the compressor.

Caution

•  If the SST is not properly positioned when the A/C compressor pulley is press-fit, the A/C compressor axle will interfere with the SST, possibly damaging component parts. Verify the SST and axle are properly positioned and perform the procedure very carefully.
