Abstract: A cartridge assembly for a track chain is disclosed. The cartridge assembly includes a pin that has a lubricant channel therein. The pin is accommodated in an inner bushing that also has a channel extending therethrough for accommodating the pin. The pin extends beyond either end of the inner bushing. The pin and inner bushing are partially disposed in an outer bushing that also has a channel for accommodating the pin in inner bushing. The ends of the inner bushing and pin extend beyond the ends of the outer bushing. First and second inserts are disposed at either end of the inner bushing. The first and second inserts are disposed between the outer bushing and a pair of opposing collars which are disposed on the ends of the pin beyond the inserts and beyond the ends of the inner bushing. The inserts and collars each include seals. The seals of the collars are supported by one or more thrust rings as opposed to the inserts or partially by the inserts.

Abstract: A cartridge for a track chain used to propel a track machine is disclosed. The cartridge includes a pin that passes axially through a bushing. The bushing may include two opposing ends and a cylindrical outer surface extending between the opposing ends of the bushing. Each end of the bushing includes an annular seal pocket for accommodating a seal and an annular step groove for coupling each end of the bushing to an inner track link. The bushing may be axially disposed between two inserts and the seals are track seals that engage one of the inserts. The inserts may be axially disposed between two collars and the collars are coupled to the pin. The collars may also include annular seal pockets that accommodate track seals.

Abstract: The present disclosure provides a track-type work machine including a vertical idler adjuster, a track-type work machine including a roller frame and an idler mounted proximate an end of the roller frame. The idler includes an idler shaft, and at least one support block supports the idler shaft. One or both of the idler shaft and the at least one support block includes a plurality of assembly orientations corresponding to different idler heights relative to the roller frame.

Abstract: An apparatus and method for reducing vibrational effects of track chain assembly catenary hang is disclosed. A work machine includes a pair of track roller assemblies one positioned on each side of the work machine. The vibration reducing apparatus and method includes repositioning undercarriage components to vary the catenary hang from one side of the work machine to the other.
