0103 325 Valve Bridge for Volvo and Renault Trucks

What does a valve bridge do?

This cylinder head valve bridge is a critical component within the engine's valve train system. It acts as a bridge between the rocker arm and the valve stems, allowing a single rocker arm to actuate two valves simultaneously. This design is essential for maintaining high-performance diesel engine cycles in heavy commercial vehicles.

Compatible vehicles and engines

The component is compatible with several heavy-duty engine series, including Volvo D10A, D11A, D12C, D13B, D16G, and various Renault Trucks DXi11, DXi12, and DXi13 engines. It is also suitable for Mack Granite and Pinnacle models equipped with MP7 and MP8 engines. This part ensures that the valve timing remains consistent across all cylinders.

Installation and maintenance

To ensure proper installation, technicians should inspect the guide pins and contact surfaces for any signs of uneven wear. Proper alignment is vital to prevent irregular valve lift or potential contact between valves and pistons. When replacing this part, it is recommended to check the condition of the rocker arms and pushrods to maintain system integrity.

Troubleshooting guidance

Consult your authorized distributor to ensure exact fitment for your specific engine model.
