SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
The following Service procedure outlines replacement of the A/C Compressor clutch assembly. It
is not currently provided in the Service Manual. It is STRONGLY recommended to review this
procedure thoroughly before proceeding further.
IMPORTANT PRECAUTIONS:
• Both snap rings are 1-time use items.
• CAUTION: ALWAYS wear eye protection whenever working with snap rings.
• When installing the stator and rotor snap rings, they must be installed in the proper direction.
• When removing the hub, pay close attention to the shims which may be stuck to the hub and
/ or to the end of the compressor shaft splines. The number of shims can range from zero
(0) to three (3). These shims are used to set the air gap between the hub and rotor during
reassembly.
DISASSEMBLY:
Step 1) Remove the drive belt cover, drive belt and drive belt cover bracket following the procedure
in the applicable Service Manual.
Step 2) Using the Special tools 18355AA000 (Pulley Wrench) and 18334AA020 Pulley Wrench
Pin Set, CAREFULLY hold the hub in place and loosen / remove the bolt from the center as shown
below.

Step 3) After removing the bolt, CAREFULLY remove the hub from the compressor shaft splines.
Pay close attention to the shims (small, thin washers) which may either stick to the bottom of the hub
splined portion or to the end of the compressor shaft as shown in the photos below.
IMPORTANT: Note the number of shims used (0-3) as this will be the starting point to use at
reassembly when setting the hub to rotor (pulley) air gap / clearance.
Shim is stuck in the
base of the hub bore.
Shim is stuck to the end
of the compressor shaft.
Step 4) Disconnect the clutch wire harness connector and remove the Philips screw securing the
harness clamp to the compressor. Spread the clamp (only as much as needed) to remove it from
the harness and transfer it to the new stator assembly harness in the same position using the image
below as a guide. Do not reconnect the harness at this point.
Remove this harness
clamp screw.

Step 5) Using snap ring pliers, remove (and discard) the “wavy” snap ring securing the rotor (drive
pulley). Slide it forward to remove it and expose the stator (magnet).
Step 6) Using snap ring pliers, remove (and discard) the flat “outside” snap ring securing the stator
(magnet). Remove it to expose the positioning groove on the front face of the compressor housing.
Stator (Magnet) Positioning Groove
REASSEMBLY:
Step 7) Fit the new stator assembly to the compressor. VERY IMPORTANT: The protrusion
(locating pin) on the back of the stator face MUST fit into the positioning groove on the compressor
as shown above.

Step 8) Inspect both new snap rings and identify the “beveled” side of each as shown.
Inner (Stator)
Snap Ring
Beveled Edge
Outer (Rotor)
Snap Ring
Beveled Edge
Step 9) Install the stator and it’s snap ring first then install the rotor (pulley) and it’s outer “wavy”
snap ring. IMPORTANT: The beveled edge of both snap rings must always face front (forward) at
reassembly. Always confirm each snap ring is fully seated in its receiving groove before proceeding.
Step 10) Insert the retaining bolt through the hub and install the same number of shims used on
the original clutch onto the bolt. Install the hub onto the compressor shaft being careful to not
lose any of the shims. Just snug (do not fully tighten or torque) the retaining bolt at this point.
REMINDER: Due to manufacturing tolerances, the shim requirement may range from 0 to 3 to
achieve the proper air gap (clearance).
Step 11) Using a feeler gauge, measure the air gap between the back face of the hub and front face of
the rotor (pulley) as shown. The air gap specifications are:
• .35mm, +.15 / -.1mm (“OK” range is from .5mm to .25mm) or
• .014”, +.006” / -.004” (“OK” range is from .020” to .010”).
If the measurement is outside the specification, remove the hub as described in Step 3. Add (to
INCREASE the air gap) or remove shim(s) (to DECREASE the air gap) as needed to achieve the
necessary air gap. When the proper air gap is achieved, torque the retaining bolt to 9.75 ft. lbs. or 117
inch-lbs.

Step 12) Reinstall the drive belt and any other removed components in reverse order. Always
confirm proper system operation to complete the procedure.
