Abstract: A portable disassembly tool is provided to disassemble a track link assembly from a machine by removing opposed track links from the track link assembly. The portable disassembly tool includes first and second members that are tightly secured to the track link to be removed by a plurality of fasteners. The second member has clearance holes therein to freely receive the ends of the associated track pin assemblies. A third member having spacer members extending therefrom is disposed adjacent to the second member with the spacer members extending into the respective clearance holes into contact with the ends of the track pin assemblies and secured to the second member by a second plurality of fasteners. By alternately tightening the plurality of fasteners, the track link is pulled from the associated track pin assemblies. During the removal of the track link, binding in any direction is overcome.

Abstract: A vibratory mechanism is provided for a compacting work machine. The vibratory mechanism includes at least one eccentric weight rotatably positioned within a housing. Pressurized fluid is introduced into the vibratory mechanism at an inlet passage. A means for moving fluid through the vibratory mechanism and lubricating a pair of bearings is provided that operates during rotation of the eccentric weight.

Abstract: Endless track laying work machines are provided with a pair of track laying assemblies positioned on opposite sides of the work machine. Each track laying assembly includes an endless rubber belt entrained around a drive wheel, an idler wheel, and a plurality of mid-rollers. The present mid-roller includes a rotatable member that is positioned between individual roller segments and the guide blocks that are positioned on the inner surface of the endless rubber belt. With the rotatable member in this position, the differential angular velocity between points of contact between the rubber belt and the mid-rollers is compensated for by rotating the rotatable member independent of the individual roller segments. Thus, increasing the life of the individual drive components.

Abstract: A drive arrangement (62) for transferring rotational motion from a pin (44) of a draft arm (14,16) of a hitch assembly (10) to a position sensor (64). The drive arrangement (62) includes a driver (68) that acts as a wear compensation mechanism (66).

Abstract: Existing track laying work machines fail to provide adequate suspension for reducing shock loads transmitted to machine components and the operator. The present suspension system provides suspension members interposed the main frame of the work machine and an elongated beam supported by first and second track roller frames. Cushioning members separate the roller frame from the elongated beam and drive wheel hub, to provide further isolation from shock and torsional movement of the roller frame.

Abstract: A tension management system is provided for an endless track laying work machine. A fluid cylinder maintaining tension within the endless track. A first accumulator provides recoil for normal operating conditions. If tension on the endless track increases beyond a normal recoil situation, fluid is bled off through a pressure relief arrangement to a second accumulator. The system requires an initial fluid charge from a fluid power unit, and is then disconnected and operates as a stand alone system.

Abstract: The cooling system for a skid steer loader provides a unitary assembly that is pivotally mounted to the body portion of the loader above the engine. The unitary assembly includes a frame, first and second heat exchangers, a shroud, a guard, a drive mechanism, and a fan. During times of maintenance on the work machine the entire cooling system can be moved to a second position providing unencumbered access to the engine compartment.

Abstract: An elastomeric belt laying vehicle is disclosed for transmitting greater tractive effort to the earth as compared to comparably powered wheel vehicles and being operable at high speed on improved road surfaces without inflicting damage thereto. A pair of the wheels are arranged on each lateral side of the vehicle's chassis for support thereof. An inextensible, endless belt is highly tensioned throughout its length, is entrained about each pair of wheels, and is frictionally, drivingly coupled to at least one wheel of each pair. The structure of the belt, structure of the wheels and cooperating components thereof ensure engagement therebetween, provides long service with minimum maintenance thereof, and supplies the necessary frictional couple to effectively transmit driving torque from the wheels to the belt.
