7200 881 015 Volvo Compressor Crankshaft

What does a compressor crankshaft do?

The compressor crankshaft serves as a critical component within the air brake compressor assembly, responsible for converting the engine's rotational energy into the reciprocating motion required for air compression. Built with high-strength components, this part is essential for maintaining consistent pressure within the pneumatic braking system of heavy commercial vehicles.

Vehicle and engine compatibility

This specific crankshaft is designed for use in various Volvo truck models, including the F10, F12, N12, and N10 series. It is compatible with several engine types such as the TD101, TD122, TD120, and TD70. Additionally, it fits Volvo B12 and B10M models using TD120 and TD100 engines. This component is compatible with Knorr-Bremse systems.

Installation and maintenance

To ensure optimal performance and prevent system failures like excessive vibration or pressure loss, technicians should inspect the crankshaft during regular compressor overhauls. Proper installation is vital to maintain the integrity of the internal seals and bearings. Check the compatibility list to confirm fitment for your specific engine series.

System performance guidance

Regular maintenance of the compressor assembly helps prevent secondary damage to other pneumatic components. When replacing the crankshaft, it is recommended to inspect all connected moving parts to ensure the entire compression cycle remains efficient under heavy-duty operating conditions.
