Volvo Trucks offers a new fifth wheel option, which is installed directly into a truck’s frame. The smaller, lighter design preserves ride and drive quality and weighs 165 pounds, 100 pounds less than current standard-duty fifth wheel systems. It can handle a vertical load of 50,000 pounds and a drawbar pull of 150,000 pounds.
Affected tractors are equipped with an automated Eaton UltraShift Plus or Eaton Advantage Transmission with right hand stalk shifter. In the affected trucks, the display on the instrument panel can indicate “N” when the shifter is set into “D” or “R,” causing the truck not to move.
