Abstract: A recoil system for a track roller frame of a track assembly is provided including a spring, a track adjust cylinder and an end plate. A rear support member is connected to the end plate and a pivot shaft connecting member of the track roller frame. A track adjust piston is received in the track adjust cylinder. The spring is arranged with a first end abutting against the track adjust cylinder and a second end abutting against the end plate. The track adjust cylinder and the track adjust piston are movable in first and second directions in response to movement of an idler with movement of the track adjust cylinder in the second direction compressing the spring against the end plate. A front support assembly is configured to support the track adjust piston relative to the track roller frame while permitting movement of the track adjust piston in the first and second directions.

Abstract: A recoil system for a track assembly having a track roller frame and an idler movable is provided. The recoil system includes a spring, a track adjust cylinder, an end plate and a track adjust piston received in the track adjust cylinder. The track adjust cylinder and the track adjust piston are movable in first and second directions in response to movement of the idler with movement of the track adjust cylinder in a second direction compressing the spring against the end plate. The track adjust cylinder is adapted to rotate with the first end of the spring relative to the track adjust piston as the spring compresses and extends in response to movement of the track adjust cylinder in the first and second directions and wherein the second end of the spring is fixed against rotation relative to the end plate.

Abstract: An idler yoke assembly for a track system of a track-type machine is disclosed. The assembly includes a yoke configured to support an idler wheel of the track system and is operatively coupled with a tensioning member of the track system. The yoke further includes a first arm having a first keyway and a wear strip secured to the first keyway. The wear strip is configured for sliding engagement with a key of the track system as the yoke moves relative to a track roller frame of the track system.

Abstract: An equalizer bar end joint may include a pin defining a longitudinal axis; and a bearing configured to support the pin. The bearing may include an inner race including a bore configured to cooperate with the pin and a semispherical outer surface. The bearing may also include an outer race including a semispherical inner surface, wherein the semispherical inner surface of the outer race is configured to cooperate with the semispherical outer surface of the inner race. A solid lubricant may be disposed about a surface of the bore, and a first seal may be positioned within a first groove disposed about the bore at a first end and a second seal may be positioned within a second groove disposed about the bore at a second end.

Abstract: The disclosure describes, in one aspect, a bearing assembly including an outer portion and an inner portion adapted to receive an end of a bar. The inner portion includes a fluidic groove extending from a first end of the bearing assembly to a second end of the bearing assembly permitting fluid to flow through the first end and the second end.
