303.04.0131.03 Repair Kit for ECAS Solenoid Valves

What does an ECAS solenoid valve repair kit do?

An ECAS solenoid valve repair kit is a service set designed to renew the worn elements inside the solenoid valve blocks of an electronically controlled air suspension system. This kit typically includes essential sealing elements such as O-rings, gaskets, diaphragms, the plunger, and the spring to restore optimal performance.

Compatible vehicles and engines

The valve block maintains constant chassis height by filling and venting the air bellows according to control unit commands. This kit is compatible with Knorr-Bremse systems and is suitable for use in various heavy commercial vehicles, including Volvo FM, FH, and VNL series, Renault Trucks Premium and Magnum, Ford Trucks Cargo and F-MAX models, as well as Mack Granite and Pinnacle trucks.

Installation and maintenance

For workshop technicians, using a repair kit allows for the refurbishment of the valve block without the need for a complete replacement, significantly reducing vehicle downtime. When performing installation, ensure all ports are clean and inspect the plunger movement to prevent future leaks or delayed level responses.

Troubleshooting and maintenance

Regular inspection of these sealing elements can prevent sagging while parked or improper pneumatic response. Check the integrity of the diaphragms and O-rings during routine suspension maintenance to ensure the stability of the electronic control system.
