303.11.0056.02 Exhaust Brake Valve Repair Kit for Heavy Duty Engines

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-duty commercial vehicle engines. This kit typically contains gaskets, O-rings, a diaphragm, a flap seal, and the necessary springs or pins required for a complete service. By replacing only the sealing and moving components exposed to compressed air and exhaust gas, the valve housing can be retained, offering a cost-effective alternative to full valve replacement.

Vehicle and engine compatibility

This repair kit is compatible with various heavy-duty applications, including Renault Trucks models such as the C series, KERAX, PREMIUM 2, T series, K series, MAGNUM, and Volvo models including FH, FM, FMX, and VNL. It is suitable for diverse engine configurations including DXi, DTI13, D11K, D13K, and others found in these heavy commercial vehicles.

Maintenance and installation guidance

For workshop technicians performing maintenance, this kit ensures that the exhaust gas flow restriction system operates according to OE tolerances. When inspecting the exhaust brake system, check for leaks or loss of compression resistance during long descents. Ensuring all seals are seated correctly during installation helps maintain the integrity of the pneumatic actuator and the butterfly valve flap.

System performance and selection

Selecting a high-strength component ensures reliable performance under intense thermal and pneumatic stress. Check the compatibility list to ensure this kit matches your specific engine model.
