Claim 16:
17. A track pin for a track joint assembly in a ground-engaging track system comprising:
a solid, one-piece pin body defining a longitudinal axis extending between a first pin end having a first terminal end surface, a second pin end having a second terminal end surface, and a center section extending between the first pin end and the second pin end;
the center section includes a first lead-in chamfer and a second lead-in chamfer formed adjacent to the first pin end and the second pin end for interference-fitting, respectively, a first portion and a second portion of the center section with inboard link straps in the first track chain and the second track chain;
the solid, one-piece pin body has a full axial length;
the first pin end and the second pin end each have a pin end axial length;
the center section has an enlarged diameter, relative to the first pin end and the second pin end, and a center section axial length;
the enlarged diameter is greater than the pin end axial length; and
the center section axial length is from 60% to 63% of the full axial length, and from 314% to 318% of the pin end axial length.
