2. Install the clutch coil lead wire harness retaining clip on the compressor front housing and tighten the retaining screw.
3. Install the clutch field coil and snap ring with snap ring pliers (Special Tool C-4574). The bevel side of the snap ring must be facing outward.
Also, both eyelets of the snap ring must be to the right or left of the pin on the compressor. Press in on the snap ring to be certain that it is properly
seated in the groove.
CAUTION: If the snap ring is not fully seated in the groove it will vibrate out, resulting in a clutch failure and severe damage to the front housing
of the compressor.

4. Install the pulley assembly onto the compressor. If necessary place a block of wood on the friction surface and tap gently with a hammer.
CAUTION: Do not mar the pulley friction surface.
5. Install the pulley assembly retaining snap ring (bevel side outward) with snap ring pliers (Special Tool C-4574). Press in on the snap ring to be
certain that it is properly seated in the groove.
6. If the original clutch plate assembly and pulley assembly are to be reused, the old shim(s) can be used. If not, place a stack of shim(s) equal to the
old shim(s) on the shaft against the shoulder.
7. Install the clutch plate assembly onto the shaft.
8. With the clutch plate assembly tight against the shim(s), measure the air gap between the clutch plate and the pulley face with feeler gauges. The
air gap should be between 0.35 to 0.65 millimeter (0.014 to 0.026 inch). If the proper air gap is not obtained, add or subtract shims as needed
until the desired air gap is obtained.
9. Install the compressor shaft bolt. Tighten the bolt to 13 Nm (115 in. lbs.).
NOTE: The shims may compress after tightening the shaft bolt. Check the air gap in four or more places to verify the air gap is still correct. Spin
the pulley before performing a final check of the air gap.
