A4271300008 Cylinder Liner Set for Mercedes-Benz

What does a cylinder liner set do?

This compressor cylinder liner set serves as a critical service kit designed to restore the internal cylinder surface where the piston travels. By providing a precise bore diameter, this component helps maintain the integrity of the compression chamber within heavy-duty air brake compressors. Using high-strength components ensures long-term durability under intense pneumatic pressure.

Compatible vehicle applications

This specific liner set is compatible with Mercedes-Benz applications. It is used in various compressor configurations, including single or twin-cylinder units, to ensure consistent air pressure delivery for heavy commercial vehicles. For optimal performance, technicians should verify the cooling type and cylinder count during selection.

Installation and maintenance guidance

When installing this liner set, it is vital to ensure the cylinder bore is free of contaminants and that all sealing components are seated correctly. Maintaining cleanliness during assembly prevents premature wear of the piston rings and ensures the restored compression chamber meets operational standards.

Troubleshooting pressure loss

If you observe increased oil consumption or air leakage from the compressor housing, a liner replacement is often the most effective way to restore pressure-generating capacity without replacing the entire unit.
