A track work vehicle includes a track system including a drive wheel supported by an axle housing that drives a continuous ground-engaging track, a saddle assembly that guides the track about the drive wheel and an undercarriage frame that supports one or more idler wheels that guide the track along a ground surface. The track work vehicle further includes a fender assembly that includes at least one fender coupled to the axle housing to overlap a portion of the track.

A torque-resistant dual face seal includes a seal ring having an L-shaped cross-section including an axially-extending flange and a radially-extending flange, the seal ring including an annular seal face and an opposing annular loading surface. The seal ring includes a plurality of deformations formed in a spaced apart arrangement circumferentially around the axially-extending flange. An axial cross-section through the axially-extending flange and intersecting one of the plurality of deformations includes a stepped geometry. The plurality of deformations allows a load ring to squeeze into the plurality of deformations to increase a surface area contact between the seal ring and the load ring.

A clamping master track link includes a body that defines a first bore and a second bore, a first aperture disposed between the first bore and the second bore, a second aperture disposed between the first aperture and the second bore, a first strut with a first gap disposed between the first aperture and the second aperture, a second strut with a second gap disposed between the first aperture and the first bore, and a bridge disposed between the second aperture and the second bore. The first bore defines a cylindrical bore surface that is at least partially textured.

A method for manufacturing a seal is disclosed. The method includes depositing one or more layers of a first material on a metal base plate of a second material to form a main seal body of the seal. The second material is different from the first material. The method further includes separating the seal from the metal base plate such that the seal includes the main seal body and an outer seal layer retained on the main seal body to form a seal face surface of the seal. The outer seal layer is formed of a portion of the metal base plate.

A face seal member includes a cylindrical annular body defining a cylindrical axis, a radial direction, a first axial extremity, a second axial extremity, an outside radial extremity and an inside radial extremity, a face sealing surface including a clearance surface, a contact region disposed radially adjacent the clearance surface that defines a contact plane, and a tapered surface extending radially from the contact region that defines a taper angle with the contact plane that increases as the tapered surface progresses further radially from the contact region toward the inside radial extremity.

A mounting arrangement for a tensioning device with a tensioning unit in a side carrier of a crawler of a tracked undercarriage in a large machine is disclosed. The tensioning unit is arranged in a side carrier compartment in the side carrier of the crawler, wherein a mounting opening is arranged in the side carrier on the outside thereof in an installation area of the tensioning unit for allowing removal of the tensioning unit, when installed, from the side carrier compartment through the mounting opening transversely to a track running direction.
