1. Assemble the Clutch Coil, Pulley Rim and the Clutch Rotor and Bearing assembly as shown in Figure 27. Use new screws and apply sealer GM
12345382 (Loctite 242, or equivalent) to screw threads but do not lock the screws in place.
2. Place the assembly on the neck of the Front Head and seat into place using Rotor & Bearing Installer J 26271-A (Fig. 14).
Before fully seating the assembly on the Front Head, be sure the clutch coil terminals are in the proper location in relation to the compressor and
that the three protrusions on the rear of the clutch coil align with the locator holes in the Front Head.
3. Install the rotor and bearing assembly retaining ring and reassemble the Clutch Plate and Hub assembly. Check to see that the clutch plate to clutch
rotor air gap is 0.5-7.6mm (0.020-0.030").
Rotate the Pulley Rim and Rotor to be sure the Pulley Rim is rotating "in-line" and adjust or replace as required.
4. Tighten the pulley rim mounting screws to 11 N.m (100 in.lbs.) torque and lock the screw heads in place by bending screw head washer, similar to
original crimp and lock bends on washers.
