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 retainer sleeve (70) for use with a lock (60) in a ground engaging tool (10). The retainer sleeve can include a skirt (72) extending part way around a retainer axis (75) to form a portion of an annulus. The retainer sleeve can further include a plurality of legs (71a, 71b, 71c, 71d, 71e) joined to the skirt and formed to mate with a lock cavity (40) of the ground engaging tool. The plurality of legs can form an inner surface (79) shaped to rotatably receive an outer surface (66) of the lock.

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.
