These radiator cores are only available through the parts system at this time.
--------------- END SUPPLEMENT ---------------
Description of Change: New radiator cores have improved resistance against blasting. The rear row of tubes are now made of Cu-Ni replacing the brass tubes on the fan side (the tube row opposite the direction the vent tubes face). Use of the alloy and thicker tubes results in ten times more resistance to blasting than brass tubes.
Adaptable To: The new radiator cores are adaptable to all D8R (9EM1-Up, 7XM1-Up) and D9R (8BL1-Up, 7TL1-Up) Track-Type Tractors.
