303.11.0065.02 Exhaust Brake Valve Kit for Scania

What does an exhaust brake valve repair kit do?

An exhaust brake valve repair kit is an overhaul set used to renew the internal components of a valve that provides engine braking on heavy 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 using this kit, the existing valve housing is retained while the components exposed to exhaust gas and compressed air are renewed to restore supplemental braking effect.

Compatible Scania vehicles and engines

This repair kit is compatible with Scania trucks and buses across several series, including Scania R, P, G, S, T, and K models. It fits various engine configurations such as DC 13, DC 12, DC 09, DT 12, and DT 16. Whether servicing a Scania P series or an R series chassis, these kits ensure the engine compression resistance is maintained for safe operation.

Installation and maintenance guidance

For workshop technicians, performing a targeted repair with this kit is often more efficient than a full valve replacement. During installation, it is critical to inspect the valve housing for any signs of excessive wear or debris before installing the new sealing elements. Proper maintenance helps prevent loss of engine braking power in heavy-duty applications.

Troubleshooting and service tips

Regular inspection of the exhaust brake system can prevent unexpected downtime. If the engine braking effect feels diminished or if there are leaks around the valve housing, consult your authorized distributor.
