7400 920 010 Air Brake Compressor Bushing Equivalent

What does a compressor bushing do?

This compressor bushing serves as a critical wear component within the pneumatic air brake compressor assembly. By providing stable support for internal moving parts, it helps maintain the precise alignment necessary for consistent air pressure generation. High-strength materials are used to ensure durability under the intense thermal and mechanical stresses typical of heavy commercial vehicle braking systems.

Vehicle and engine compatibility

This bushing is compatible with various heavy-duty engines, including Caterpillar 3176, C15, and C16 models, as well as Detroit Diesel 60 Series engines. It is widely used in vehicles such as Peterbilt (379, 387, 388, 389), Freightliner (Cascadia, Coronado, Columbia), Kenworth (T600, T800, W900), and International (9200, 9400) trucks. Additionally, it fits Western Star, Sterling, and Mack Titan units.

Maintenance and installation

For optimal performance, technicians should inspect bushings during routine air system maintenance. Replacing worn bushings can prevent premature failure of the compressor piston or crankshaft. Ensure that all mounting surfaces are clean and that the bushing is seated correctly to avoid vibration or air leaks in the pneumatic circuit.

Selection guidance

Proper selection of replacement components is essential for maintaining stable air pressure output. Using high-quality bushings helps extend the service life of the entire compressor unit without requiring a full replacement.
