303.13.0001.03 Repair Kit for Height Adjustment Valves

What does a height adjustment valve repair kit do?

This repair kit for height adjustment valves is essential for maintaining the pneumatic leveling systems in heavy commercial vehicles. It provides a cost-effective solution to restore optimal air suspension performance by replacing worn internal components that maintain the correct ride height under varying loads.

Compatible vehicles and engines

The kit is compatible with Ford Trucks models such as the Cargo 2524, 1824, 3230, 2530, 3530, and 1830, as well as Volvo vehicles including the B10B, NL12, N12, F10, FL12, F7, B12, F12, B10M, and N10. It is also fitted to Mercedes-Benz, MAN, Scania, Renault Trucks, and DAF trucks. For exact fitment, ensure the kit matches the existing valve's arm length and port configuration.

Installation and maintenance guidance

When performing maintenance, always depressurize the air system before disassembly to prevent injury from flying components. It is critical to mark the existing arm angle before removal to ensure the valve is reset to the same reference position during installation. Clean all sealing surfaces thoroughly to prevent leaks caused by dust or oil residue.

System troubleshooting

Regularly inspecting the valve assembly can prevent uneven tire wear and instability. If a leak is detected at the valve body or ports, a full inspection of the bellows and air lines is recommended to ensure complete system integrity.
