303.11.0109 Compatible Gearbox Housing Valve

What does a gearbox housing valve do?

This gearbox housing valve acts as a critical pneumatic control component mounted directly on the transmission housing of heavy commercial vehicles. It is responsible for managing gear and range shifts by directing pressurized air to the working cylinders and maintaining pressure once a range change is completed. By regulating air flow, it ensures smooth transitions during operation.

Compatible vehicles and engines

This component is compatible with heavy commercial vehicle brands including Mercedes-Benz, MAN, DAF, Iveco, and Renault Trucks. It is engineered to meet the rigorous demands of trucks and tractor units used in demanding logistics environments. For precise fitment, ensure the port sizes match your specific requirements.

Installation and maintenance

The unit features one M12x1,5 port and two M14x1,5 ports to facilitate secure connection within the transmission system. Technicians should inspect these ports for debris and ensure all seals are seated correctly during installation to prevent air leaks. Regular checks of the pneumatic lines are recommended to maintain optimal shifting performance.

Selection guidance

When replacing this valve, verify that the current unit's port configuration matches the vehicle's specific gearbox requirements to avoid system pressure loss.
