A lube skid apparatus configured to be moveable and transportable. The lube skid having one or more tanks carried by a scaffold of the lube skid. One or both tanks having sloped bottom walls to optimize flow of fluids in the tanks to minimize residual fluid left in the tank. One or both tanks having sloped top walls configured to contain and direct the flow of fluid spills on the skid to an adjacent sump. The skid also carries a plurality of service devices such as a motor, an air compressor, a tank to hold compressed air, pumps to move fluid with associated filters and hoses, and one or more service storage drawers.

A system. The system includes a valve assembly. The valve assembly includes a first port, a second port fluidically couplable with the first port upon application of negative pressure at the first port, a third port fluidically couplable with the first port upon application of positive pressure at the first port, and a first check valve positioned between the first port and the second port. The system also includes a second check valve fluidically couplable with the third port upon the application of the positive pressure at the first port. The second check valve is positioned external to the valve assembly.

A fluid system of a machine. The fluid system includes a fluid reservoir, a pump coupled to the fluid reservoir, a filter coupled to the pump and a valve assembly. The valve assembly includes a first port, a second port coupled to the first port and to the fluid reservoir, a third port coupled to the first port, and a first check valve positioned between the first port and the second port. The fluid system further includes a second check valve positioned between the filter and the third port.

The present invention relates to an electric grease barrel pump that has a single pumping structure and has an automatic shift function performed by a manual operation of a valve for switching a grease supply line. The electric grease barrel pump comprises: a pumping means; a driving means; a supply pipe through which the grease is discharged from the pumping means; a distribution valve installed at an end of the supply pipe in a direction in which the grease is discharged; a magnetic switch, installed at a movable portion of the distribution valve, for outputting a signal for supplying the grease to a selected grease supply target of the plurality of grease supply targets according to an operating position of the movable portion; and a control unit for controlling the driving means to adjust grease discharge capability of the pumping means according to the signal of the magnetic switch.

A grease tool and method for greasing a wheel bearing where the grease tool includes a handle and manifold. The handle and manifold define a central passage that extends through the grease tool. A supply channel is formed radially between the central passage and an exterior surface of the grease tool and extends axially through the handle to an annular supply recess formed in the manifold. A grease fitting attached to the grease tool to facilitate a supply of grease through the supply channel and the supply recess to an inwardly facing surface of the wheel bearing. The central passage in the grease tool facilitating sliding the grease tool over an axle that extends through the wheel bearing and positioning of the grease tool within the wheel bearing evenly repacking of the bearing in a position over the axle.
