Abstract: A ground engaging tip (14) of a ground engaging tip assembly (10) includes an adapter (12) configured for attachment to the base edge of the implement and having a forwardly extending adapter nose (20). The ground engaging tip has a rear edge (52), a top outer surface (54), and a bottom outer surface (56). The top and bottom outer surfaces extend forward from the rear edge and converge at a front edge (58) of the ground engaging tip. The tip has first and second side outer surfaces (57, 59) extending forward from the rear edge of the ground engaging tip to the front edge. The tip has a nose cavity (38) for receiving the adapter nose therein. The tip has a support rib (130) 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.

Abstract: A retainer sleeve (70) for use with a lock (60) in a ground engaging tool (10). The retainer sleeve may include an outer skirt (73) extending around a retainer axis (75), where the outer skirt may include an outer surface (76) formed to mate with a lock cavity (43) of the ground engaging tool. The retainer sleeve can further include an inner skirt (74) flexibly connected to the outer skirt via a lower bend (71). The inner skirt may be formed to rotatably receive an outer surface (66) of the lock. The retainer sleeve may also include a detent projection (77) extending radially inward from the inner skirt with respect to the retainer axis and formed to engage a detent recess (67) of the lock to releasably hold the lock.

Abstract: A ground engaging tip (14) of a ground engaging tip assembly (10) includes an adapter (12) that attaches to the base edge and having a forwardly extending adapter nose (20). The tip has a rear edge (52) and a top and bottom outer surfaces (54, 56). 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 (58). The tip includes first and second side outer surfaces (57, 59) extending forward from the rear edge to the front edge. Tip includes a nose cavity (38) for receiving the adapter nose therein. The nose cavity has first and second side inner surfaces (111) opposite the first and second side outer surfaces, respectively. The nose cavity has an aperture (36) and a retention channel (110) 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 (50) of the adapter into the aperture during installation of the ground engaging tip on the adapter. The retention channel has an untapered portion (112) and a tapered portion (114), 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 ground engaging tip (14) of a tip assembly (10) for a base edge (8) of a ground engaging implement (1) has an adapter (12) configured for attachment to the base edge of implement and having a forwardly extending adapter nose (20). The ground engaging tip has a rear edge (52), a top outer surface (54), and a bottom outer surface (56). 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 (58) of the ground engaging tip. The ground engaging tip also has a nose cavity (38), 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 (92) extending from an inner surface of the nose cavity (84, 94, 96), into the ground engaging tip, toward the bottom outer surface of the ground engaging tip.

Abstract: In some implementations, a retainer sleeve may include a body including an at least partially annular configuration defining a retainer axis. The body may include an inner surface configured to rotatably receive an outer surface of a lock. The body may include a plurality of plates circumferentially joined together with respect to the retainer axis, where a first plate of the plurality of plates includes a first leg joined to the first plate extending away from the retainer axis and configured to contact a lock cavity of the lock. The body may include an anti-rotation feature, disposed on the first plate, extending inward from the inner surface toward the retainer axis, the anti-rotation feature including a locking surface configured to contact a lock skirt of the lock, the locking surface disposed at a first angle with respect to a bottom end of the first plate.

Abstract: A ground-engaging tool system (110) includes an adapter (112) attachable to a work implement (100) and a ground-engaging tip (114) that is releasably connectable to the adapter (112). To releasably mate the adapter (112) and the tip (114), the adapter (112) may include a projecting lug post (162, 164) that locks and unlocks with a rotatable, latch-like retainer (180, 182) in the tip (114). The lug post (162, 164) may be a frustum or frustoconical structure having a truncated flat (204) and an exterior side surface (200) that intersect at a peripheral edge (206). The shape of the truncated flat (204), peripheral edge (206), and exterior side surface (200) may further be delineated by a first radius (222) and a second radius (232) of different dimensions, or by radii having first and second centers (224, 234) that are not coincident in location on the truncated flat (204).

Abstract: A filter media (62) includes flutes (72), forward plugs (78), and aft plugs. Each of the flutes (72) has a forward flute face, an aft flute face, and a flute body defining a flute conduit to convey the fluid. The forward plugs (78) are disposed in alternating ones of the flutes (72). Each forward plug (78) includes a plug base and an aerodynamic plug nose (90) (90). The aerodynamic plug nose (90) (90) has a center axis (100) and a nose surface (94) tapering outwardly from the center axis (100) towards the plug base. The plug nose (90) is configured to aerodynamically redirect a flow of the fluid away from the center axis (100). The flutes (72) that have forward plugs (78) include a flute outlet disposed at the aft flute face. The aft plugs are disposed in the flutes (72) adjacent to the flutes (72) that have corresponding forward plugs (78). The flutes (72) that have aft plugs include a flute inlet (76) disposed at the forward flute face.
