3094156 Volvo F12 TD122 Compressor Ring

What does a compressor ring do?

This compressor ring plays a critical role in maintaining the compression efficiency of the air brake compressor within the engine system. Manufactured from high-strength components, these rings are designed to withstand the intense thermal and mechanical stresses encountered during continuous operation in heavy commercial vehicles.

Compatibility with Volvo engines

This specific component is designed for use in Volvo F12 trucks equipped with TD122 engines. It serves as a precise replacement to restore optimal sealing and pressure within the cylinder bore, ensuring the air brake system operates according to manufacturer standards.

Installation and maintenance

During installation, technicians must ensure that the ring thickness matches the piston groove height exactly to prevent rattling or binding. It is highly recommended to install a complete set of rings during an overhaul to maintain set integrity and consistent compression across all grooves.

Troubleshooting and selection

For optimal performance, always verify that the ring diameter matches the piston diameter and check the end-gap clearance against the current service manual. Consult your authorized distributor for further assistance.
