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 retainer sleeve configured for use in a retainer system for a ground engaging tool includes a plurality of plate-like sections, each section being flexibly joined with an adjacent section along either a radially inner edge or a portion of a radially outer edge. The radially inner edges of the plurality of sections form part of a segmented inner surface configured for engagement with an outer surface of a locking member of the retainer system. The inner surface extends partially around a central axis of the retainer sleeve to form a substantially C-shaped retainer sleeve having opposite circumferential ends that are spaced from each other. The radially outer edges of the plurality of sections form part of a segmented, frustoconical outer surface configured for engagement in an internal lock cavity of a ground engaging tool tip.

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 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.
