7400 920 020 Bushing, Air Brake Compressor Repair Kits

The heavy-duty grade bushing is an essential component within the air brake compressor repair kit system. Designed to provide structural stability and reduce friction during high-pressure cycles, this part ensures the long-term operational integrity of the compressor assembly. By utilizing high-strength components, it maintains precise tolerances required for heavy commercial vehicle air systems.

7400 920 020 is the OE-equivalent bushing used in Detroit Diesel DD13 and DD15 engines, as well as in various Mercedes-Benz and Freightliner Cascadia heavy commercial vehicle applications. This part is also compatible with systems from Knorr-Bremse and Bendix. Its precise engineering ensures seamless integration into existing pneumatic compressor architectures, supporting reliable air supply for braking systems.

For workshop technicians, this bushing is designed for straightforward assembly during routine maintenance or overhaul of the air compressor. It is critical to verify the specific engine model, such as the Detroit Diesel DD13 or DD15, to ensure perfect fitment. Regular inspection of compressor components helps prevent pressure drops and maintains optimal braking performance in fleet operations.
