  3. 85V113000Received . 5,020 units.

    Service Brakes, Air

    The dual double check valve may not release the proper air volume to the brake system, causing a slight timing delay between the tractor and the trailer brake system. Consequences of defect: if the brakes are suddenly applied, the trailer could jackknife without warning to the operator, which could result in a vehicle crash.
    Remedy, in the NHTSA record
    Install two new sleeves in the dual double check valve which will increase air flow.

    Trailer Hitches / Fifth Wheel Assembly

    Defect, in the NHTSA record
    Due to improper and inadequate welding practices, the fifth wheel on the involved vehicles is defective. Frame mounted supports may have incomplete or poor quality welds. The welds could subsequently fail allowing separation of the tractor from the trailer.
    Remedy, in the NHTSA record
    The dealer will inspect and remove the fifth wheel and reweld the mounting angles at no charge to the owner.

  6. 84V035000Received . 850 units.

    Service Brakes, Air / Supply / Check Valve

    Defect, in the NHTSA record
    A manufacturing error resulted in the installation of carbon steel springs in some dual-compartment air reservoir check valves. Carbon steel springs are inadequate for this application because they are subject to severe corrosion and subsequent failure of the check valve.
    Remedy, in the NHTSA record
    The carbon steel spring will be replaced with a stainless steel one.
