Abstract: An idler group is disclosed for a mobile machine having a tracked undercarriage with an endless track. The idler group may include a retainer disposed on an axle and within an opening in an idler. The retainer may be configured to achieve an interference fit with the idler sufficient to hold the retainer within the opening of the idler during operation of the mobile machine. In another embodiment, a retaining ring may be disposed within a channel formed in the idler and may contact the retainer. In yet another embodiment, a swaged connection may be formed between the idler and the axle.

Abstract: A track link is disclosed for use with an undercarriage of a machine. The track link may have a body with a first surface and a second surface opposite the first surface. The track link may also have a shoe face extending between the first and second surfaces at a side of the body, and a roller rail extending between the first and second surfaces at a side of the body opposite the shoe face, The body may have a substantially uniform hardness of about 45 to 55 Rkw C between the shoe face and the roller rail.
