1697706 Volvo TD120 Compressor Piston Replacement

What does a compressor piston do?

This compressor piston plays a critical role in the pneumatic compression cycle, converting reciprocating motion into high-pressure air for the braking system. Manufactured with heavy-duty grade materials, it is designed to withstand the high-pressure and thermal stresses found in heavy commercial vehicle air brake compressors.

Vehicle compatibility and engine fitment

This specific component is engineered for Volvo N12 trucks equipped with the TD120 engine. It maintains precise tolerances to ensure optimal compression and long-term durability within the cylinder assembly.

Installation and maintenance guidance

For correct installation, technicians should verify the piston diameter and ring groove configuration against the existing unit. It is recommended to inspect the cylinder liner for wear and ensure all seals are replaced during assembly to maintain system integrity.

Selection and verification

Always confirm fitment by checking the compressor housing markings to ensure this piston matches your specific engine configuration.
