Automatic Level Control: Servicing: Compressor: Lubrication
If compressor functions, but output pressure is low, the second stage cylinder surface and piston felt ring may need lubrication. To lubricate, remove compressor from vehicle. Remove six through-bolts and carefully separate the two halves of compressor. Apply lubricant to felt ring and cylinder wall. Reassemble compressor and re-test. If unit still fails to function, replace.
