303.02.0001.01 Ford Trucks Compatible Repair Kit

What does a protection valve repair kit do?

This multi-circuit protection valve repair kit is a complete replacement component set prepared for overhauling the multi-circuit protection valve that manages several air lines from a single housing in the pneumatic brake circuit of heavy commercial vehicles. By providing high-strength components to renew internal seals, this kit helps maintain critical pressure distribution across service, parking, and auxiliary circuits.

Compatible Ford Trucks models and engines

This kit is compatible with Ford Trucks Cargo series, including models like the Cargo 3238, 1838T, 2535, and 3532, especially those equipped with Ecotorq 7.3 and 9.0 Euro 5 engines. It is also fitted to other heavy vehicles such as Faun, Mercedes-Benz, VDL, DAF, Scania, Solaris, and Iveco trucks. The kit ensures that even if a leak develops in one specific circuit, the remaining pneumatic circuits remain operational to maintain vehicle control.

Installation and maintenance guidance

For workshop technicians performing maintenance, it is essential to verify the valve's circuit count and housing type before installation. This kit is suitable for restoring the internal sealing and pressure balance of valves used in Ford Trucks Cargo 4136, 1826, 2526, 2532, 3232, 1835, 3235, 3536, 2536, 3236, 2538, and 3936 models. Proper installation ensures the pneumatic system maintains its intended response speed.

Troubleshooting brake system pressure

When troubleshooting brake system pressure drops, inspect the diaphragm and O-rings within the protection valve. Using a high-quality repair kit allows for efficient component renewal without the need to replace the entire valve assembly. Consult your authorized distributor for more information.
