Machine and track assembly for use therewith

A track chain assembly for a ground engaging track comprising:

• an outboard track link having a first bore formed therein;
• an inboard track link having a second bore formed therein, the second bore having a longitudinal bore axis and extending between an outboard side and an inboard side of the inboard track link;
• and
• a cartridge pin coupling the outboard track link to the inboard track link, and including an outboard collar and an outer track seal positioned within the first bore, and an inboard collar and an inner track seal positioned within the second bore;
• the inboard track link further having a seal region adjacent to the second bore, and an inboard face for protecting the inner track seal, positioned radially outward of the seal region and axially inboard of the second bore, the second bore being defined by unhardened material of the link body, and the inboard face including a hardened sacrificial wear material, and being configured to contact a projecting step on a rotatable track engaging element guiding or driving the ground engaging track, such that impingement of the rotatable track engaging element upon the seal region is inhibited.

A ground engaging track comprising:

• a first chain assembly including a plurality of outboard track links and a plurality of inboard track links;
• a second chain assembly including another plurality of outboard track links and another plurality of inboard track links;
• and
• a plurality of cartridge pins coupling together the first and second chain assemblies, each of the cartridge pins including a first and a second outboard collar each having an outer track seal positioned therein, and a first and a second inboard collar each having an inner track seal positioned therein;
• each of the inboard track links of the first and second chain assemblies having a bore formed therein extending between an outboard side and an inboard side of the corresponding inboard track link, and receiving an inboard collar and an inner track seal of one of the cartridge pins;
• and
• each of the inboard track links further having a seal region adjacent to the corresponding bore, and an inboard face for protecting the corresponding inner track seal, each of the bores being defined by unhardened material of the link body, and each of the inboard faces including a hardened sacrificial wear material and being positioned radially outward of the bore.
