Mercedes Benz Truck WABCO Compressed Air Filter & Pressure Relief Valve Assembly

Reassembly of a 1995 Mercedes Benz 1024 truck’s WABCO 432 series compressed air filter & pressure relief valve’s components.

A quick exploded parts view of a pressure relief valve’s innards and how they are reassembled.

Included is a view of what caused the pressure relief valve to vent all compressed air headed toward the truck’s pressure tanks to atmosphere, rendering the truck immobile until it was bypassed and subsequently repaired.

Will hopefully provide insight into dissecting and rebuilding faulty WABCO 432 series units similar to the one found on my truck.
