A centerfill assembly for a lubricant reservoir includes a hollow tube for receiving lubricant from the top of the reservoir and loading the lubricant into the reservoir near the bottom of the reservoir. Loading the lubricant near the bottom of the reservoir introduces lubricant near where the stirring paddles mix the lubricant and near where the lubricant is loaded to the lubricant pump. Adding the lubricant near where the pumps load and near the stirring paddles helps to eliminate air pockets in the lubricant. In addition, having the centerfill rod minimizes exterior plumbing and allows for the mounting of valves on the fill line.

An oil storage and filtration system for an engine unit includes an on/off valve that defines an operating phase when receiving supply air and in an on position and a standby phase when in an off position or not receiving the supply air. The system also includes a fill/drain valve that defines a drain state and a fill state which respectively correspond to emptying and filling oil from/into the engine unit. The system also includes a control valve, a pressure/vacuum valve, and a storage tank. The storage tank stores oil in a pressurized condition during the fill state, a vacuum condition during the drain state, and an atmospheric condition during the standby phase. The also includes a vacuum generator in fluid communication with the storage tank during the drain state and fluidly isolated from the storage tank during the fill state.

In one embodiment, there is provided a dock for a replaceable fluid container for an engine, the fluid container having: a fluid reservoir; and at least one fluid port having a coupling adapted to couple with a fluid circulation system associated with the engine; the dock having: a fastening mechanism configured to cooperate with the container such that, as the container is inserted into the dock, the fastening mechanism acts first to seat the fluid container in the dock but in an undocked condition and then, as the container is inserted further into the dock, acts to bring the fluid container into an engaged condition in which the fluid container is docked with a docking interface of the dock.

A power unit replaceable fluid container, the power unit being in fluid connection with a fluid distribution system, is disclosed. The container comprises a generally cuboid housing adapted to contain a fluid, the housing having a continuous outer wall, a base portion closing one end of the outer wall and a lid portion situated opposite the base portion and closing a second end of the outer wall to form a container. An indent is provided in the base portion and a fluid inlet and a fluid outlet situated within the indent. The indent in the base portion is sized to receive and accommodate a removable manifold.

A grease tool and method for greasing a dual angular contact bearing where the grease tool is fabricated from a single unitary piece of material. The grease tool comprises a cylindrical hub, a flange supported adjacent only one end of the cylindrical hub, and a grease fitting attached to the grease tool to facilitate a supply of grease thereto. During use, a pair of spaced apart O-rings, accommodated by an exterior surface of the cylindrical hub, form a pair of grease seals with an inwardly facing surface of an inner race of the dual angular contact bearing. A supply passage conveys the supplied grease from the grease fitting to a grease outlet(s) located in an exterior cylindrical surface of the grease tool, between the pair of O-rings, for conveyance of the supplied grease radially to the inner race of the dual angular contact bearing and facilitate repacking thereof.

An apparatus comprising: an identity determiner configured to determine an identity of a removable fluid container; a characteristic determiner configured to obtain a first characteristic based on testing the fluid of the fluid container; a data obtainer configured to obtain a second characteristic based on the identity; and a processor configured to control a fluid provider to provide fluid from the removable fluid container based on the comparison of the first characteristic and the second characteristic.
