There are two primary types of bushings on a D8R, often categorized by their sealing system, which corresponds to different generations of the undercarriage:
Standard Bushing (Used with "C" Series Seals): The earlier style.
Sealed and Lubricated Bushing (Used with "M" Series Seals): The more advanced, standard system for the D8R, which allows for internal lubrication of the pin/bushing joint.
This 258-0769 bushing is used for D8T D8R dozer.
