7421136656 Piston & Ring for Renault Trucks Ø80,00mm

What does a compressor piston & ring do?

This compressor piston and ring set is a critical component for maintaining the air pressure within the pneumatic braking system. It functions by compressing air within the cylinder to ensure the pneumatic system operates with consistent pressure. These components are manufactured using high-strength materials to withstand the intense thermal and mechanical stresses found in heavy commercial vehicle engines.

Compatible Renault Trucks models

This specific assembly is designed for Renault Trucks models, including the Premium, Magnum, and Kerax series. It is compatible with DXi11, DXi12, and DXi13 engines. These parts ensure that the compressor maintains optimal compression ratios for vehicles operating under heavy-duty loads.

Installation and maintenance guidance

When performing maintenance, technicians should verify the cylinder liner condition before installation. This Ø80,00mm standard size is intended for liners that have not been previously machined. Ensure all ring grooves are cleaned and that end-gap clearances align with the manufacturer's service manual to prevent premature wear or binding.

Maintenance and troubleshooting

Regular inspection of the piston and rings can prevent significant pneumatic system failures. If scoring is observed on the piston skirt or if air leakage is detected within the compression chamber, a complete replacement of this component is recommended to restore system integrity.
