Add a tiny drop of oil to the 0.4 mm (0.016 in) air gap shim then position the shim between the clutch drive plate components before assembling the compressor clutch plate. After verifying the drive plate doesn't touch the pulley during rotation, measure the distance between pulley and drive plate and adjust the shims to maintain a 0.3-0.6 mm (0.012-0.024 in) air gap. Use the universal spanner wrench (J 37872) to secure the compressor clutch plate motionless while installing the new clutch drive plate bolt with colored adhesive distributed across at least 5 threads.
