Description of Change: An improved radiator core is available for the machines listed above. The new radiator core has a plate-type reinforcement at the ends of the core instead of the strip-type reinforcement used in the former radiator core. The plate-type reinforcement stabilizes and distributes the vertical loads across the four outer end rows instead of two outer end rows.
Adaptable As: The improved radiator cores are direct replacements for the former radiator cores shown in Chart A. Machine applications for the new radiator cores are shown in Chart B.
