5001831273 Piston & Ring for Renault Trucks MAGNUM

What does a compressor piston and ring do?

This compressor piston and ring set is designed to restore optimal compression within the air brake system of heavy commercial vehicles. The piston functions as the primary moving component within the cylinder, while the rings ensure a tight seal to prevent air leakage and manage lubrication, maintaining the necessary pressure for braking performance.

Compatible Renault Trucks MAGNUM models

This specific component is compatible with Renault Trucks MAGNUM models, including various engine configurations such as the AE 420ti.24T, AE 470.19, and AE 560.18T. It is specifically engineered to meet the requirements of these heavy-duty engines to ensure reliable operation under high-pressure conditions.

Installation and maintenance guidance

During installation, technicians should verify that the piston diameter matches the cylinder bore exactly and check that the ring grooves are free of debris. It is recommended to inspect the cylinder liner during overhaul to ensure proper seating for the new rings. For exact clearance specifications, always refer to the vehicle manufacturer's service manual.

Troubleshooting and replacement

Regular inspection of these components can prevent sudden loss of air pressure in the braking system. When replacing worn parts, it is best practice to replace the full set to maintain system integrity.
