Installation (All Models Except Grand Cherokee)

Align pin in back of field coil with hole in compressor end housing, and position field coil into place. Make sure that lead wires are properly routed, and fasten the diode and coil wire bracket with retaining screw.
Install field coil retaining snap ring with snap ring pliers. Press snap ring to make sure it is properly seated in the groove.

CAUTION: If snap ring is not fully seated it will vibrate out, resulting in a clutch failure and severe damage to the front face of the compressor. DO NOT mar the pulley frictional surface.

NOTE: The bevel side of the snap ring must be outward. Also both eyelets must be to the right or left of the pin on the compressor.

Install pulley assembly to compressor. If necessary, tap gently with a block of wood on the friction surface. See Fig 5.
Install pulley assembly retaining snap ring (bevel side outward) with snap ring pliers. Press the snap ring to make sure it is properly seated in the groove.

NOTE: The bevel side of the snap ring must be facing outward.

If the original front plate assembly and pulley assembly are to be reused, the old shim(s) can be used. If not, place a trial stack of shims, 0.10" (2.54 mm) thick, on the shaft against the shoulder.
Install front plate assembly onto shaft.
If installing a NEW front plate and/or pulley assembly, the gap between front plate and pulley face must be checked. Use the following procedure:
- Attach a dial indicator to front plate so that movement of the plate can be measured.
- With the dial indicator zeroed on the front plate, energize the clutch and record the amount of movement.
- The readings should be 0.014-0.026" (0.35-0.65 mm). If proper reading is not obtained, add or subtract shims until desired reading is obtained.
Install compressor shaft bolt. Tighten to 135-175 INCH Lbs. (15.5-19.5 N.m).

NOTE: Shims may compress after tightening shaft nut.

Check air gap in 4 or more places to verify if air gap is still correct. Spin pulley for final check. Install the accessory drive belts.
