7200 922 016 Volvo and Renault Compressor Crankshaft

What does a compressor crankshaft do?

The compressor crankshaft serves as a critical component within the air brake compressor assembly. It is responsible for transferring rotary motion from the engine to the piston, directly influencing the compression performance of the entire pneumatic system. This component is manufactured using high-strength components to withstand the rigorous demands of heavy commercial vehicle operations.

Vehicle and engine compatibility

This crankshaft is compatible with various heavy commercial vehicle models, including Volvo FH (FH4/FH5), FM, FMX, VNL, B11R, B13R, and Mack Anthem. It is also fitted to Renault Trucks T and C models with DTI13 or DTI11 engines. The part is designed to work seamlessly within Knorr-Bremse systems.

Maintenance and installation guidance

When performing maintenance or an overhaul of the air brake compressor, inspecting the crankshaft is essential to prevent noise or vibration issues. Technicians should ensure all mounting points are clean and verify that the crankshaft rotates freely before final installation to maintain system integrity.

System performance importance

Selecting a high-quality replacement helps maintain consistent air pressure delivery throughout the braking circuit. For optimal performance, always verify compatibility with the specific engine type of the vehicle.
