2. Clean the surfaces of the clutch plate (1) and clutch rotor (2) before installing the clutch plate and hub assembly.
3. Align the shaft key with the shalt keyway and place the clutch plate and the hub assembly onto the compressor shaft.

4. Remove the remover-installer center screw and reverse the body direction on the center screw as shown in (Figure 5).
5. Install the clutch plate and hub installer J 33013-B with bearing as shown in Figure 5.
^ Back the body of the hub and drive plate installer tool off enough to allow the center screw to be threaded onto the end of the compressor shaft.

8. Place a feeler gage between the clutch plate and the clutch rotor.
9. Tighten the hex portion of the hub and drive plate installer until the air gap between the clutch plate and clutch rotor is 0.40 mm (0.015 inch).
^ Make sure that the air gap is even all around the clutch plate and hub assembly.
10. Remove the J 33013-B.
11. Hold the clutch plate and hub assembly (2) with the J 33027-A.
