704 250 Cylinder Liner compatible with Caterpillar

What does a cylinder liner do?

This compressor cylinder liner is a critical component used to restore the internal cylinder bore where the piston travels within an air brake compressor. By providing a smooth, durable surface, it ensures the compression chamber maintains necessary pressure levels. This part is essential for maintaining the efficiency of pneumatic braking systems in heavy commercial vehicles.

Compatible vehicles and engines

The component is designed for use in various heavy-duty applications, including Freightliner, Kenworth, Western Star, International, Mack, and Peterbilt trucks. It is specifically compatible with Caterpillar C15, C16, and 3176 engines. This liner ensures proper fitment for models such as the Kenworth T800, Peterbilt 389, and Freightliner Cascadia.

Installation and maintenance

When performing a compressor overhaul, technicians should inspect the cylinder walls for scoring or uneven wear. Replacing the liner helps prevent air leakage and excessive oil consumption without requiring a full compressor housing replacement. Ensure all sealing surfaces are clean during installation to maintain system integrity.

Troubleshooting and selection

For optimal performance in high-pressure environments, selecting a liner that meets exact specifications is vital to prevent loose fitment or premature wear.
