Abstract: A component for a track-type machine comprises a body, a through-bore extending through the body forming an inner wall, and a bushing located in the through-bore. The bushing comprises a bearing surface, an outer surface engaging the inner wall, a flange extending from the outer surface and extending into the inner wall, and retention features located in the outer surface proximate the flange. The retention features comprise voids in the bushing filled-in by material of the body. Methods of manufacturing a component for a track-type system comprises casting-in-place a bushing with a flange and retention features into the component.
