7400 920 020 Compressor Bushing for Detroit Diesel Engines

What does a compressor bushing do?

The compressor bushing serves as a critical component within the air brake compressor assembly, facilitating smooth internal movement and maintaining structural alignment. By providing a durable bearing surface, it helps prevent excessive vibration and ensures the pneumatic system maintains consistent air pressure delivery for the braking system.

Vehicle and engine compatibility

This part is designed for use in heavy commercial vehicles, including Freightliner, Kenworth, and Western Star models. It is specifically compatible with Detroit Diesel engines such as the DD13, DD15, and DD16 series, as well as the 60 Series. It is also fitted to Mercedes-Benz trucks.

Installation and maintenance

For optimal performance, technicians should inspect bushings during routine air system maintenance. Replacing worn bushings can prevent secondary damage to the crankshaft or connecting rods. Proper installation ensures the compressor maintains its sealing function and pressure output under heavy-duty operating conditions.

System reliability

Maintaining the integrity of the compressor internals is vital for the overall reliability of the vehicle's pneumatic brake system.
