7400 700 005 Compressor Bushing for Heavy Vehicles

What does a compressor bushing do?

This compressor bushing serves as a vital component within the pneumatic air brake compressor assembly, ensuring stable movement and structural integrity of the internal reciprocating parts. By utilizing high-strength components, this bushing helps maintain the necessary tolerances required for consistent air pressure delivery in heavy-duty braking systems.

Vehicle and engine compatibility

This component is fitted to various heavy commercial vehicles, including Kenworth W900 and T800 models, Peterbilt 379 and 389 series, and Freightliner Cascadia or Columbia models. It is specifically designed for use with Caterpillar C15, C16, and 3176 engines, providing a reliable fitment for heavy-duty applications in Mack TITAN and International 9400I trucks.

Installation and maintenance

During installation, technicians should ensure the compressor housing is thoroughly cleaned of old residue to prevent contamination. Proper alignment of the bushing within the compressor block is essential to prevent premature wear of the piston or connecting rod assembly. Regular inspection of these bushings during routine air system maintenance can prevent sudden pressure loss.

System reliability

Maintaining stable air pressure depends on the precision of these small but critical components. When servicing Caterpillar-powered engines in Western Star or International fleets, selecting a high-grade bushing ensures long-term reliability for the entire pneumatic system.
