New Cylinder Liner Available {1216}
Usage:
D336 Industrial And Marine Engines, 621 ( 23H ) Tractors And 980 ( 42H ) Loaders
Description of Change: A new cylinder liner is available for the above engines and machines. The former cylinder liner had a machined groove on its upper surface. Movement between this groove and the head gasket could cause excessive wear on the head gasket. The new cylinder liner does not have the groove on the top surface. This should result in improved head gasket life.
Adaptable As: The new 7C9522 Cylinder Liner is a direct replacement for the former 7S8715 Cylinder Liner in the above engines and machines. The former 7S8715 Cylinder Liner is canceled.
