7000 703 500 Cylinder Liner Set for Air Brake Compressors

What is a compressor cylinder liner set?

A Compressor Cylinder Liner Set is a service kit consisting of the liner and essential sealing components used to restore the cylinder bore where the piston travels inside an air brake compressor. By replacing the worn liner, the compression chamber is returned to its original dimensions, preventing air leakage and pressure loss without the need to replace the entire compressor housing.

Engine and vehicle compatibility

This component is essential for maintaining pneumatic system integrity in heavy commercial vehicles. It is compatible with various engines, including Detroit Diesel Series 60 and Caterpillar C15, C16, and 3176. These sets are frequently fitted to Freightliner, Kenworth, Peterbilt, International, Western Star, and Mack trucks to ensure reliable braking performance.

Installation and maintenance guidance

When installing this kit, technicians should ensure the cylinder housing is thoroughly cleaned of all old residue. It is critical to verify that the liner dimensions match the specific engine requirements to prevent loosening during operation. Following the manufacturer's torque specifications during assembly is vital for a long-lasting seal.

Troubleshooting and selection

Regular inspection of the cylinder walls can help identify early signs of wear before they lead to significant pressure drops in the braking system.
