    Abstract: A retainer sleeve for use with a lock in a ground engaging tool. The retainer sleeve can include a skirt extending part way around a retainer axis to form a portion of an annulus. The retainer sleeve can further include a plurality of legs joined to the skirt and formed to mate with a lock cavity of the ground engaging tool. The plurality of legs can form an inner surface shaped to rotatably receive an outer surface of the lock.

    IPC: E02F9/28

    Abstract: A ground engaging tip of a ground engaging tip assembly includes an adapter that attaches to the base edge and having a forwardly extending adapter nose, and a ground engaging tip. The tip has a rear edge and a top and bottom outer surfaces. The top and bottom outer surfaces extend forward from the rear edge of the ground engaging tip and converge at a front edge of the tip. The tip includes first and second side outer surfaces extending forward from the rear edge to the front edge. Tip includes a nose cavity for receiving the adapter nose therein. The nose cavity has first and second side inner surfaces opposite the first and second side outer surfaces, respectively. The nose cavity has an aperture and a retention channel on at least one of the first and second side inner surfaces. The retention channel extends from the rear edge to the aperture and guides a lug of the adapter into the aperture during installation of the ground engaging tip on the adapter. The retention channel has an untapered portion and a tapered portion, with the tapered portion extending from the rear edge to the untapered portion and the untapered portion extending from the tapered portion to the aperture.

    IPC: E02F9/28

    Abstract: A ground engaging tip of a ground engaging tip assembly includes an adapter configured for attachment to the base edge of the implement and having a forwardly extending adapter nose. The ground engaging tip has a rear edge, a top outer surface, and a bottom outer surface. The top and bottom outer surfaces extend forward from the rear edge and converge at a front edge of the ground engaging tip. The tip has first and second side outer surfaces extending forward from the rear edge of the ground engaging tip to the front edge. The tip has a nose cavity for receiving the adapter nose therein. The tip has a support rib on at least one of the first or second side outer surfaces, the support rib being positioned at the rear edge and extending lengthwise from the bottom outer surface toward the top outer surface.

    IPC: E02F9/28

    Abstract: A ground engaging tip of a tip assembly for a base edge of a ground engaging implement has an adapter configured for attachment to the base edge of implement and having a forwardly extending adapter nose. The ground engaging tip has a rear edge, a top outer surface, and a bottom outer surface. The top outer surface and the bottom outer surface extend forward from the rear edge of the ground engaging tip and converge at a front edge of the ground engaging tip. The ground engaging tip also has a nose cavity, within the ground engaging tip and defined between the converging top and bottom outer surfaces of the ground engaging tip, for receiving the adapter nose therein. The nose cavity includes a wear indicator extending from an inner surface of the nose cavity, into the ground engaging tip, toward the bottom outer surface of the ground engaging tip.

    Abstract: A filter media includes flutes, forward plugs, and aft plugs. Each of the flutes has a forward flute face, an aft flute face, and a flute body defining a flute conduit to convey the fluid. The forward plugs are disposed in alternating ones of the flutes. Each forward plug includes a plug base and an aerodynamic plug nose. The aerodynamic plug nose has a center axis and a nose surface tapering outwardly from the center axis towards the plug base. The plug nose is configured to aerodynamically redirect a flow of the fluid away from the center axis. The flutes that have forward plugs include a flute outlet disposed at the aft flute face. The aft plugs are disposed in the flutes adjacent to the flutes that have corresponding forward plugs. The flutes that have aft plugs include a flute inlet disposed at the forward flute face.
