Scheme 20

Scheme 21

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 male 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. Apply battery positive voltage to the magnetic clutch terminal and connect the A/C compressor body to the ground. Wrap the drive belt, which is no longer of use, tightly around the A/C compressor pulley. Hold the drive belt in place with pliers. Remove or install the bolt. Tightening torque 11.8-14.7 N.m {1.21-1.49 kgf.m, 8.7-10.8 ft.lbf}

Scheme 22

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

Scheme 23

Scheme 24

1. Remove the A/C compressor pulley using the SST (49 0839 425C) . CAUTION: Be careful that the SST (49 0839 425C) tabs do not hang over the stator.

Scheme 25

1. Align the positioning pin with the hole of A/C compressor body and insert.

Scheme 26

1. Install the inner wheel of the pulley using a plastic hammer and SST (49 B018 003) 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 that the SST and axle are properly positioned and perform the procedure very carefully.

Scheme 27

1. First, insert the 1 mm (0.039 in) thick shim into the shaft.

Scheme 28

1. Measure the clearance around the entire circumference between the pressure plate and A/C compressor pulley using a thickness gauge.
2. Inspect the clearance. If not within the specification, adjust the clearance by changing the shim or the number of shims. Magnetic clutch clearance 0.3-0.6 mm {0.012-0.023 in}

Scheme 29

Scheme 30
