7421353473 S3 Crankshaft for Renault Trucks K DTI11

What does a compressor crankshaft do?

This compressor crankshaft is a critical component that rotates within the air brake compressor crankcase to facilitate the compression process. By converting the rotational energy from the engine into linear motion via the connecting rod, it ensures the consistent production of compressed air required for the vehicle's braking system. Built with high-strength components, it is designed to withstand the intense mechanical stress found in heavy commercial vehicle applications.

Vehicle and engine compatibility

This part is specifically fitted to Renault Trucks K series trucks featuring DTI11 engines. It serves as a direct replacement to restore optimal compression performance and system reliability in heavy-duty service environments.

Installation and maintenance

For professional installation, technicians should verify the crankshaft journal dimensions and ensure all seals and bearings are inspected during assembly. Proper alignment is essential to prevent premature wear of the compressor's internal components. Check the compatibility list to ensure correct fitment.

Troubleshooting and performance

If the compressor exhibits increased noise or vibration, inspecting the crankshaft and its associated bearings is a recommended diagnostic step to prevent complete system failure.
