303.11.0056.01 Renault Trucks Exhaust Brake Valve Repair Kit

What is an exhaust brake valve repair kit?

An exhaust brake valve repair kit is an overhaul set used to renew the worn internal components of the valve that provides engine braking on heavy commercial vehicle engines. This kit typically contains essential sealing elements such as gaskets, O-rings, a diaphragm, and flap seals, as well as the necessary springs or pins required for a complete overhaul. By replacing these specific components, the valve housing can be returned to service, providing a cost-effective alternative to full valve replacement.

Compatible vehicles and engines

This component is essential for maintaining the engine brake system in various heavy-duty vehicles. It is compatible with Renault Trucks models including K series, Kerax, Magnum, C series, Premium 2, T series, and various Volvo models such as FH, FM, FMX, and VNL. These kits are specifically engineered to support engines like the DXi, DTI11, DTI13, and D13 series used in these heavy-duty applications.

Installation and maintenance

To ensure proper function, technicians should inspect the valve during scheduled maintenance intervals. When replacing the kit, verify that all seals are seated correctly to prevent air or exhaust leaks. Proper installation helps maintain the necessary in-cylinder pressure required for supplemental braking effect during long descents or loaded highway driving.

Selection guidance
