5001831273 MAGNUM DXi Compressor Piston & Ring

What does a compressor piston and ring do?

This compressor piston and ring set plays a vital role in the air brake system by maintaining precise compression within the cylinder. Manufactured from high-strength components, these parts are designed to withstand extreme thermal and mechanical stress during continuous operation, ensuring consistent air pressure delivery for the vehicle's pneumatic systems.

Compatible Renault Trucks MAGNUM models

This specific kit is compatible with Renault Trucks MAGNUM models equipped with DXi engines, including variants such as the 480.24, AE 420ti.24T, and AE 560.18. It serves as a direct replacement for the original components to restore optimal volumetric efficiency in the compressor.

Installation and maintenance guidance

When performing an overhaul, it is essential to verify that the 78.00mm diameter matches the current cylinder bore exactly. Technicians should inspect the ring grooves for wear and ensure the end gap complies with manufacturer specifications to prevent air leakage or excessive oil consumption.

Troubleshooting air pressure issues

Regular inspection of these components can prevent sudden loss of air pressure in the braking system. Always consult your authorized distributor to ensure exact fitment for your specific engine configuration.
