2500 030 100 Compressor Repair Kit for Heavy Trucks

What is a compressor repair kit?

An air brake compressor repair kit is a complete component set used to overhaul pneumatic brake compressors on heavy commercial vehicles without requiring a full unit replacement. These kits typically include essential parts such as pistons, piston rings, connecting rods, and gasket sets to restore compression and sealing functions.

Vehicle and engine compatibility

This kit is compatible with Cummins engines found in various heavy-duty applications, including Volvo VNL 300 and VNX 400 models, Kenworth T800 and T880 series, Peterbilt 379 and 579 trucks, and Freightliner Century Class vehicles. It also serves various bus and tractor unit models such as Orion VII, Volvo WG, and Peterbilt 367, ensuring consistent air pressure delivery across diverse fleets.

Installation and maintenance

To ensure proper installation, technicians should inspect the cylinder liner and valve assembly during the overhaul process. Maintaining these components helps prevent low air pressure or brake lag. Using high-strength components during maintenance ensures the longevity of the pneumatic system.

Troubleshooting guidance

Regular inspection of the compressor components is vital for fleet safety. If you notice a drop in air pressure or unusual noise from the compressor, check the seals and piston rings for wear. Check the compatibility list to ensure correct fitment for your specific engine model.
