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.

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. 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 skirt can form an inner surface shaped to rotatably receive an outer surface of the lock.

Abstract: A ground-engaging tool system includes an adapter attachable to a work implement and a ground-engaging tip that is releasably connectable to the adapter. To releasably mate the adapter and the tip, the adapter may include a projecting lug post that locks and unlocks with a rotatable, latch-like retainer in the tip. The lug post may be a frustum or frustoconical structure having a truncated flat and an exterior side surface that intersect at a peripheral edge. The shape of the truncated flat, peripheral edge, and exterior side surface may further be delineated by a first radius and a second radius of different dimensions, or by radii having first and second centers that are not coincident in location on the truncated flat.

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.
