Clutch

You must remove the accessory Drive Belt from both the A/C Compressor and the lower air deflector before performing removal of the compressor clutch assembly. Important: for the j 37872 (Compressor Clutch Holding Tool) replace the three adjust d dowels with three 5/16x1 inch bolts. The j 37872 (Compressor Clutch Holding Tool) holds the compressor clutch plate stationary while the bolt is discarded before clutch plate removal. Use j 6083 (Snap Ring Pliers) to remove the compressor pulley snap ring then remove the compressor pulley from the compressor before performing the same sequence for the compressor clutch coil snap ring and coil. Before compressor clutch plate bolt installation you must tap its threads with an m6x1.0 tap before blowing out any debris with compressed air. The installation of the compressor clutch coil and its snap ring should be performed with the j 6083 (Snap Ring Pliers) while subsequent installation of the compressor pulley and its snap ring requires the same tool (J 6083 (Snap Ring Pliers)). Place a small amount of oil on the 0.4 mm (0.016 in) air gap shim before setting it inside the clutch drive plate while you install the compressor clutch plate. Important: make sure the drive plate avoids contact with the pulley when you rotate it. Adjust the shims to create a 0.3 to 0.6 mm (0.012 to 0.024 in) air gap by measuring the spacings between the pulley and drive plate. Important: new drive plate bolts must contain colored adhesive for five threads before final installation. Notice: fastener notice applies. Each compressor clutch drive plate bolt installation requires the use of the j 37872 (Compressor Clutch Holding Tool) to prevent clutch plate movement before securing the bolt at 12 n.m (106 lb in). To complete the procedure reinstall the lower air deflector followed by installing the accessory Drive Belt to the A/C Compressor then conduct a leak test on all fittings using the j 39400-a (Halogen Leak Detector).

In order to replace the compressor clutch assembly, start by removing the accessory Drive Belt from the a/ c compressor, as well as the lower air deflector. Remove the compressor clutch plate bolt and use the compressor clutch holding tool (J 37872) to hold the compressor clutch plate to prevent it from turning. Take off three adjustable dowels off from the compressor clutch holding tool (J 37872) and replace them with three 5/16x1 inch bolts. Then we remove the compressor clutch plate, and we then proceed to use the snap ring pliers (J 6083) to remove the compressor pulleys snap ring and the compressor pulley. Again remove the compressor clutch coil snap ring using the snap ring pliers (J 6083) and then remove the compressor clutch coil. Clean the clutch plate bolt threads using 6x1.0 m tap and blow out debris using compressed air. Install the compressor clutch coil and the compressor clutch coil snap ring with the snap ring pliers (J 6083). Mount the compressor pulley and its snap ring by using the snap ring pliers (J 6083). Use a drop or two of oil, and slide it behind the drive plate of the clutch before assembling it with the compressor clutch plate. Use a vernier caliper to measure the air gap between the pulley and the drive plate, and adjust the shims so that the air gap equals 0.3-0.6 mm (0.012-0.024 in), and make sure, when rotating the drive plate, it has to slide without dragging on the surface of pulley. Some nuts of bolt must also have colored adhesive on some of their threads, at least five, and its torque should be 12 n.m (106 lb in) using the compressor clutch holding tool (J 37872) holding the compressor clutch plate from turning. Lastly, replace the lower air deflector, refit the the accessory Drive Belt to the A/C Compressor, and carry out a leak test on the fittings using the halogen leak detector (J 39400-A).

Measure the air gap and adjust the shims to achieve a 0.3-0.6 mm (0.012-0.024 in) air gap, ensuring the drive plate does not drag against the pulley when rotated.

Ensure the drive plate does not drag against the pulley when rotated, measure the air gap between the pulley and the drive plate, and adjust the shims to achieve a 0.3-0.6 mm (0.012-0.024 in) air gap.

Use the Snap Ring Pliers (J 6083) to remove the compressor clutch coil snap ring before taking out the compressor clutch coil.

Use the Snap Ring Pliers (J 6083) to remove the compressor pulley snap ring, followed by the compressor pulley itself.
