Make certain that the front of the A/C compressor is directly under the A/C clutch field coil, with the positioning tabs and wire harness correct. Fit the positioning tabs on the field coil into the grooves on the front of the compressor and use a two jaw puller, compressor field coil installer and spacer to tighten the coil beneath the front cover. Attach the clutch field coil wire lead and bracket to the A/C compressor using a 4 Nm (35 in. lbs.) tightened screw. Adjust the pulley and bearing assembly in the front of the A/C compressor while tapping, since a clear sound change signals the assembly is properly set. Use the included special tool and a hammer to fix the pulley and bearing assembly against the outside of the compressor until the snap ring is fully in the groove, to make sure the clutch won't fail. Place the snap ring (2) with the help of pliers such as Special Tool 9764 or its equivalent, to attach the pulley and bearing to the compressor. See that there is sufficient space between the compressor housing and the pulley and bearing assembly for the clutch field coil wire. To replace a clutch assembly, start with the original shims-if it is the first time and no clutch was before, use the 1.0, 0.50 and 0.13 millimeter shims from the kit instead. Put the clutch shims onto the compressor shaft and, using a strap wrench, fasten the bolt that attaches the clutch plate to the compressor to 15 Nm (133 in. lbs.). Lay a 90° wire gauge between the clutch plate and the pulley and bearing assembly; if the gap is too small, add shims and if the gap is too large, remove shims until the gap is 0.35 to 0.65 millimeter (0.014 to 0.025 inch). Place the A/C compressor onto the bracket and bolt it in place. Attach the engine wire harness to the compressor clutch field coil, position the accessory drive belt and again link the negative battery cable to the battery. After that, complete the Clutch Break-in Procedure.
