7400 850 007 Renault Trucks Compressor Bushing

What does a compressor bushing do?

This compressor bushing is a vital component within the air brake compressor assembly, designed to maintain precise mechanical alignment during operation. By reducing friction and supporting rotating elements, it helps ensure stable air pressure output and prevents premature wear of the pneumatic system. These high-strength components are engineered to withstand the rigorous thermal and mechanical stresses found in heavy commercial vehicle applications.

Vehicle and engine compatibility

The part is specifically fitted to Renault Trucks PREMIUM series, including models such as the Route 320.19, Route 370.19, and Distribution 320.26, particularly those equipped with DCI 6 engines. It is also compatible with WABCO systems and other major pneumatic configurations used in heavy-duty transport.

Installation and maintenance

For workshop technicians, inspecting bushings during routine compressor maintenance is essential to prevent oil leaks or loss of compression. When replacing these components, ensuring proper lubrication and correct seating within the compressor housing is critical for long-term reliability. Consult your authorized distributor to ensure exact fitment.

Troubleshooting and selection

Regular monitoring of the air brake system can help identify bushing wear before it leads to significant pneumatic failure or increased engine load.
