Abstract: A system for lubricating a pivot interface defined between adjacent components of a work vehicle may include a shaft and a shaft housing configured to receive an axial portion of the shaft such that the shaft housing is configured to rotate relative to the shaft. The system may also include an end cap installed relative to an end of the shaft housing and a sealing device configured to seal a radial gap defined between the shaft housing and the shaft at a seal location when a fluid pressure within the housing is below the seal's cracking pressure. Additionally, when the fluid pressure within the housing exceeds the cracking pressure, the sealing device may be configured to transition to an unsealed state to allow lubricant contained within the housing to flow axially between the sealing device and the shaft and be subsequently purged from the housing.

Abstract: A system for protecting at least one tube extending between articulating joints of a work machine including a first guard configured to be at least partially inserted inside a first opening formed in a second portion that is pivotably connected to a first portion. A second guard is configured to be at least partially inserted inside a second opening formed in the third portion that is pivotably connected to the second portion and near the first portion. The first guard and the second guard form a protective passageway for a tube extending from the first portion to the third portion, the passageway substantially preventing contact between the at least one tube and surfaces of the second portion and the third portion in close proximity with the corresponding pivotable connections.
