Abstract: A method of servicing a track chain assembly includes loosening a fastener to reduce a clamping force of a track link body on a track bushing. With the clamping force reduced, the method includes rotating the track bushing from a first position wherein a worn side of the track bushing faces a drive sprocket to a second position wherein an unworn side of the track bushing faces the drive sprocket. Once the track bushing in the second position, the method includes tightening the fastener to increase the clamping force on the track bushing. The method can be performed while leaving the track chain in place on a track machine.

Abstract: A track pad of an articulating track system for a machine is disclosed. The track pad includes a ground engaging portion and a body portion. The ground engaging portion includes a ground engaging surface that engages the ground during operation of the machine. The body portion extends from the ground engaging portion in a direction opposite the ground engaging surface. The body portion includes a roller engaging surface distal to the ground engaging surface. The roller engaging surface is a convex surface that matches the curvature of a roller surface for a roller of the machine.

Abstract: A track roller includes a body having an annular configuration defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation. The body also defines a thru-hole extending axially through the body that is centered on the axis of rotation. A blind void is disposed annularly about the axis of rotation, the blind void being spaced radially away from the thru-hole a predetermined minimum distance, forming a cantilever portion defining a flex point and a flex radial distance measured radially from the flex point to the thru-hole.
