301.02.0086.03 Compatible Air Dryer Valve Repair Kit — Ford Trucks

What does an air dryer valve repair kit do?

This air dryer valve repair kit serves as a comprehensive rebuild set for the desiccant-equipped purge valve within a heavy commercial vehicle's air brake system. By replacing the worn gaskets, springs, and pins, this kit restores the valve's ability to discharge condensed water and oil from the tank bottom in a controlled manner. Utilizing high-strength components ensures long-term reliability under harsh operating conditions.

Vehicle and engine compatibility

This kit is specifically engineered for Ford Trucks models, including various Cargo series such as the 3532, 3227, 4136, 2538, 3936, 3236, 2536, 2526, 2535, 3232, 1835, 2520, 2517, 3235, 1826, 1838T, 1832, 2532, 3238, and 3536. It is also compatible with several other heavy commercial vehicles from brands like Scania, MAN, DAF, and Iveco.

Installation and maintenance guidance

To ensure proper function, technicians should check the thread surfaces and discharge channels during installation. If excess water is found in the tank or if there is an extended fill time during operation, replacing the pin and spring assembly within this kit is highly recommended. Always verify that all connections are tight to prevent micro-leaks in the pneumatic circuit.

Troubleshooting and system health

Regular maintenance of the purge valve helps prevent moisture buildup that can lead to brake system failures. By selecting a high-quality kit compatible with WABCO systems, you can extend the service life of the air dryer without needing a full unit replacement.
