Abstract: An undercarriage system for a track-type machine includes an idler height adjustment system having piston assemblies supported in a frame, in opposition to one another, to contact upper and lower sides of an idler support element or block. A conduit connects the piston assemblies and has therein a fluid exchange valve adjustable to an open position where a flowable material such as grease is exchanged through the conduit between the piston assemblies, and a closed position where fluid connection between the piston assemblies is blocked and idler height is fixed.

Abstract: A ground-engaging track system includes a track having a first track chain and a second track chain, and an idler having pockets formed in an outer idler rim to receive inboard rail protrusions on track links in the first track chain and the second track chain. The inboard rail protrusions project from an inboard link side, and a central pad of an upper rail surface in the track link includes an anti-scalloping bump-out formed on the inboard rail protrusion.

Abstract: A track chain assembly comprises a plurality of interlocking track chain members wherein each track chain member defines a track chain traveling direction, a lateral direction perpendicular to the track chain traveling direction, and includes a shoe member defining a shoe width along the lateral direction; and a first track pad member defining a first track pad maximum width along the lateral direction, and a second track pad member defining a second maximum track pad width along the lateral direction, wherein a ratio of either track pad maximum widths to the shoe member width ranges from 1:4 to 3:4.

Abstract: A roller system for a tracked undercarriage is disclosed. The roller system includes an interconnected track shoe series. A first roller series is configured to engage a first plurality of non-adjacent track shoes of the interconnected track shoe series. A second roller series is configured to engage a second plurality of non-adjacent track shoes of the interconnected track shoe series. Rollers of the first roller series are independently mounted relative to rollers of the second roller series. Non-adjacent track shoes of the first plurality are between non-adjacent track shoes of the second plurality.
