    Abstract: A retainer includes a drive portion defining a drive portion outer diameter, and a lug receiving portion with a skirt defining a lug receiving slot that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall. The skirt also defines a skirt outer diameter that is greater than the drive portion outer diameter. Also, the drive portion has a hook tab that extends from the drive portion and that is spaced away from the skirt a minimum distance.

    Abstract: An adapter includes a first leg, a second leg, and a throat portion at least partially define a slot that defines a projection at the closed end of the slot that includes a flat middle portion straddled laterally by a first arcuate portion and a second arcuate portion, defining a lateral middle portion width. A projection protruding distance is measured along the direction of assembly from the closed end of the slot to the flat middle portion. The projection protruding distance ranges from 0.8 to 1.2 multiplied by the lateral middle portion width.

    Abstract: A retainer sleeve includes an at least partially annular body defining an axis of rotation, a radial direction, and a circumferential direction. The body may also have a radially inner annular surface defining a radially inner aperture, and a first anti-rotation feature extending radially inwardly from the radially inner annular surface including a sloping ledge having a locking surface, and an outer peripheral surface defining a notch that is at least partially aligned with the first anti-rotation feature or an array of a plurality of external ribs extending outwardly radially from the outer peripheral surface.

    Abstract: An adapter includes a first leg, a second leg, and a throat portion that define a slot defining a direction of assembly onto a work implement assembly, a lateral direction that is perpendicular to the direction of assembly, and a vertical direction that is perpendicular to the direction of assembly and the lateral direction. The throat portion further includes a first throat side surface disposed along the lateral direction and a second throat side surface disposed on the opposite side of the throat portion along the lateral direction. The first throat side surface defines a first adapter cover receiving recess.

    Abstract: A tip assembly includes a tip including a body having a narrow tip portion, a broad attachment portion that defines a concave surface, an interior disposed between the broad attachment portion and the narrow tip portion, and a cavity that leads from the concave surface toward the interior. A retention bolt that is heated includes a tapered region, and a shaft extending from the tapered region, terminating at an externally threaded end. The cavity of the tip is at least partially complimentarily shaped to the tapered region of the retention bolt.
