Abstract
An idler of an undercarriage assembly for a track-type machine is disclosed. The undercarriage assembly may have at least two links, which may be interconnected by a cartridge. The cartridge may have a bushing disposed about and rotatable relative to a pin. At least one of the links may have a link rail wear surface, which may be positioned an original wear surface height from the bushing. The idler may have a lower surface, which may be configured to wear against the link rail wear surface. The idler may also have an upper surface, which may be configured to wear against the bushing. The upper surface may be positioned radially outward of the lower surface by an original upper surface height. The original upper surface height may be between approximately 70% and approximately 90% of the original wear surface height.
