Clutch & Pulley

The replacement process starts by performing engine lift procedures before removing the right front fender liner then the retainers and deflector of the right radiator air. You should start by taking off the engine Drive Belt; a/c system discharge is not necessary during this procedure. Begin by taking out the compressor through an engine opening after you detach the compressor mounting bolts while maintaining attachment of the compressor line. Ensure to switch out the engine support fixture (J 37872) adjustable dowels with three 5/16 x 1 inch bolts. Disassemble the compressor clutch plate bolt before fastening the universal spanner wrench (J 37872) onto the turning compressor clutch plate. First you need snap ring pliers (J 6083) to extract the compressor pulley snap ring followed by compressor pulley removal. Proceed to remove the clutch coil snap ring through the same procedure. Begin by cleaning clutch plate bolt threads using an m6x1.0 tap followed by compressed air to force out all debris. Follow the compressor clutch coil installation with its snap ring by using snap ring pliers (J 6083) followed by the compressor pulley with its snap ring. Place a 0.4 mm (0.016 in) air gap shim inside the clutch drive plate after applying a small amount of oil to its surface before installing the compressor clutch plate. While rotating the pulley check for drive plate contact around its edges before you measure the gap and add shims to maintain an air gap between 0.3-0.6 mm (0.012-0.024 in). Position the new clutch drive plate bolt with five threaded segments showing colored adhesive before tightening it to 12 n.m (106 lb in) using the universal spanner wrench (J 37872) for holding the compressor clutch plate. First mount the compressor back onto the engine and fasten its mounting bolts to 50 n.m (37 lb ft). After that, set the engine Drive Belt into place. Follow radiator air deflector installation with the right radiator air deflector then its retainers before installing the right front fender liner and performing vehicle drop.

One needs to obtain several tools before replacing the compressor clutch assembly: a compressor clutch holding tool (J 37872) together with snap ring pliers (J 6083). J 37872 compressor clutch holding tool and j 6083 snap ring pliers are required. Start by taking out the compressor and three adjustable dowels from the compressor clutch holding tool (J 37872), then install three 5/16 x 1 inch bolts. Discard the compressor clutch plate bolt and position the j 37872 compressor clutch holding tool to secure the compressor clutch plate during removal procedures. The compressor pulley snap ring can be removed using snap ring pliers (J 6083) before removing the pulley itself. The technician should use snap ring pliers (J 6083) to remove both the compressor clutch coil snap ring and coil itself. Through the installation process first use an m6x1.0 tap to clean clutch plate bolt threads before applying compressed air to clear remaining debris. Use snap ring pliers (J 6083) to install the compressor clutch coil followed by installation of the compressor clutch coil snap ring using the same tool. To begin installation use the snap ring pliers (J 6083) for attaching the compressor pulley and its snap ring. Place a 0.4 mm (0.016 in) air gap shim inside the clutch drive plate using small amounts of oil before putting on the compressor clutch plate. Normal compressor pulley rotation should not trigger drive plate contacts with the pulley. Utilize the measurement tools to check pulley-drive plate air gap distances and readjust the shims to yield between 0.3 to 0.6 mm (0.012 to 0.024 in) air gap distance. Tighten the new drive plate bolt to 12 n.m (106 lb in) after first making sure the bolt shows colored adhesive on at least 5 threads. Perform this operation while using the compressor clutch holding tool (J 37872) to stop the clutch plate from rotation. After compressor reinstallation complete a leak test on all fittings by using the leak test tool (J 39400-A).

Clean the clutch plate bolt threads with an M6x1.0 tap and blow out debris with compressed air.

Remove the compressor and the three adjustable dowels from the Compressor Clutch Holding Tool (J 37872), replacing them with three 5/16 x 1 inch bolts.

Remove the lower air deflector and take out the three adjustable dowels from the J 37872 Universal Spanner Wrench, then install three 5/16x1 inch bolts in their place.

Install the new drive plate bolt, ensuring it has colored adhesive on at least 5 threads, and tighten it to 12 Nm (106 lb in) while using the Compressor Clutch Holding Tool (J 37872) to hold the compressor clutch plate.

Install the compressor clutch coil and its snap ring using (J 6083), then install the compressor pulley and its snap ring.

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