A4031300117 Mercedes-Benz Compatible Cylinder Liner Set

What does a cylinder liner set do?

This compressor cylinder liner set is a specialized service kit used to restore the internal cylinder bore where the piston travels within an air brake compressor. By replacing the worn liner and sealing components, technicians can rebuild the compression chamber to original dimensions, effectively preventing air leakage, pressure loss, and excessive oil consumption without needing to replace the entire compressor housing.

Compatible vehicles and applications

This component is specifically designed for use in Mercedes-Benz heavy commercial vehicle applications. It is suitable for various compressor configurations, including single and twin-cylinder units used in trucks and buses. This kit ensures the compression chamber maintains the necessary structural integrity under heavy-duty operating conditions.

Installation and maintenance

For professional installation, ensure the cylinder bore is thoroughly cleaned and free of debris before assembly. Following proper torque specifications during installation is critical to maintaining a proper seal and preventing premature wear. This liner set provides a cost-effective solution for overhauling air brake compressors during routine maintenance or after detecting symptoms of pressure loss.

Troubleshooting and selection

Monitoring compression performance and checking for oil consumption can help determine when a liner replacement is required to maintain system reliability.
