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.

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

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

c. Hold the drive belt in place with pliers.

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.
