  3. 78V030000Received . 400 units.

    Service Brakes, Air / Supply / Hoses, Lines/Piping, and Fittings

    Defect, in the NHTSA record
    A design deficiency exists in the air dryer piping in the area of the pressure relief valve and compressor governor control link. Moisture is passed and builds up in this relief valve and control line. In freezing ambient temperatures, this moisture may freeze, allowing the chassis air system pressure to exceed 150 PSI. Excessive air system pressure can cause separation of air piping connections and air system valve failure.
    Remedy, in the NHTSA record
    The dealer will relocate the air system compressor governor line and pressure relief valve to eliminate moisture accumulation.
