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 bulldozer includes a folding blade that includes a base blade having opposed ends. A first blade portion is rotatably movable about an axis near one end of the base blade. A second blade portion is rotatably movable about an axis near an end of the base blade opposite the first blade portion. The first blade portion and the second blade portion are rotatably movable relative to the base blade between extended and retracted positions. Each blade portion includes a selectably removable first pin and a selectably removable second pin. When installed, the first pin secures each of the first blade portion and the second blade portion in the extended position and the retracted position relative to the base blade, and when installed, the second pin secures each of the first blade portion and the second blade portion in the extended position relative to the base blade.

Abstract: A three point hitch for a work machine includes a first and a second draft link each having a mounting end portion and a free end portion opposite the mounting end portion. Mounting end portion being mounted to a first side of a work machine to allow upward and downward pivotal movement of the free end portion beside an upwardly and downwardly extending fixed structural element of the work machine. Mounting end portion of the second draft link being mounted to a second side of the work machine opposite the first side to allow upward and downward pivotal movement of the free end portion of the second draft link. A sway restrictor mounts on the free end portion of the first draft link and restricts sideward swaying thereof toward and away from the structural element. A counterweight for use with the three point hitch is interchangeable with a fluid motor.

Abstract: The sway restrictor includes a bracket attachable between the draft link or arm and an adjacent upwardly and downwardly extending structural element of a work machine, and is operable for substantially restricting or preventing relative sideward movement therebetween, particularly swaying of the hitch, while allowing relative upward and downward movements thereof, including tilting movements.

Abstract: The disclosure involves the combination of a vehicle chassis such as that used on a construction machine, e.g., a loader/backhoe. The chassis has a channel and a holding tank, e.g., a hydraulic oil tank, supported on the channel by first and second tank mounting ears. In the improvement, the channel includes a panel having outer and inner surfaces and first and second mounting plates are against the inner surface. First and second mounting fasteners extend through the first and second tank mounting ears, respectively, through the chassis panel and into the first and second mounting plates, respectively. A new method for mounting a holding tank to a vehicle chassis is also disclosed.

Abstract: The present invention provides a wireway assembly for mounting to the housing wall of an electrical distribution device to enclose and protect electrical wiring therein. Generally rectangular, u-shaped channels have at least one aperture positioned in the channel wall to overlap the aperture of an adjacent channel to define a wireway through which the electrical wiring extends from the bight portion of one channel to the bight portion of the adjacent channel. An interlocking means manually attaches and detaches each channel with an adjacent channel and with the housing wall.The present invention also includes a method of safely protecting electrical wiring extending across a housing wall of an electrical distribution device. The method includes the step of interlocking a plurality of u-shaped channels in an abutting position to each other and the housing wall.

Abstract: A racking mechanism for a fused circuit breaker includes a drive assembly that is removable as a unit from the breaker and fuse truck. A modular assembly includes a drive unit having a drive shaft and a travelling nut and yoke for rotating a pair of levering arms for moving the breaker among a plurality of positions in a cubicle. All interlocks are included on the modular drive assembly. An indicator is cam operated by the travelling nut and includes a face having indicia that identifies the direction of rotation of the drive shaft.
