  Q: How to replace the A/C Clutch Assembly (LNF) on Chevrolet HHR?

  A: Before installing the new compressor clutch assembly (LNF) users must remove the compressor and eliminate the three adjustable dowels from the j 37872 before adding three 5/16 x 1 inch bolts as replacements. Use j 37872 to hold the compressor clutch plate before using it to remove the assembly. First extract the compressor pulley snap ring with j 6083 before removing both the compressor pulley and the compressor clutch coil snap ring with j 6083. Use the j 6083 to remove the compressor clutch coil snap ring then extract the compressor clutch coil from the assembly. Clear the threads of the clutch plate bolt using a m6x1.0 tap then sweep away debris with compressed air before installing the compressor clutch coil. Use the j 6083 to position the clutch coil snap ring before setting the compressor pulley into place using this same tool. Place a 0.4 mm (0.016 in) air gap shim inside the clutch drive plate after it receives a small amount of oil and install the compressor clutch plate while checking for pulley-drag during rotation. Measure the pulley-drive plate distance using shims to create a 0.3 to 0.6 millimeter (0.012 to 0.024 inch) air gap. Use the j 37872 to hang the compressor clutch plate while you install the clutch drive plate bolt with a minimum of 5 threads covered by colored adhesive. Tighten the bolt to 12 n.m (9 lb ft). Reinstall the compressor followed by leak testing all fittings with tool number j 39400-a.
