A ground engaging tool locking system includes a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis. The pin includes a groove located between the first, proximal head region and the second, distal end region. A biasing element is disposed at least partially within the groove.

A bolt retainer, to position a bolt within a bolt receiving element of a component, is disclosed. The bolt retainer may include a tube structure. The bolt retainer may further include bolt engaging elements that extend from an inner surface of the tube structure to engage with the bolt. The bolt retainer may additionally include component engaging elements that extend from an outer surface of the tube structure to engage with the component.

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 that faces at least partially in the circumferential direction and along a direction that is parallel to the axis of rotation, forming an oblique angle with the direction that is parallel to the axis of rotation.

A lug member is provided for a wear member retention system for an implement. The lug member includes an elongated body having a length dimension. A wear member engagement portion extends toward a distal end of the elongated body. A compression bolt assembly engaging portion is adjacent a proximal end of the elongated body. The compression bolt assembly engaging portion defines at least one bore configured to receive a compression bolt.

An attachment assembly (25) and a ground engaging assembly for releasable attachment with earthmoving equipment is disclosed. In at least one embodiment, the attachment assembly (25) comprises a first body (30) configured for being placed in affirmative engagement with a portion (32) of or in fixed relation with respect to an edge of or associated with the earthmoving equipment. The attachment assembly (25) comprises a second body (35) configured for being placed in affirmative engagement with a portion of the ground engaging tool (GET, 15.sub.C or 15). An operable element (40) is arranged so as to operably associate the first (30) and second (35) bodies so as to be responsive to operation of the operable element (40) in a first mode (mode I), in which one of the bodies (30, 35) is moved or driven away from the alternate body on the GET being received with respect to said edge, the separation of the bodies operating to apply a force to said portion of the GET for holding the GET (15.sub.C) with respect to said edge, and, a second mode of operation (mode II), in which one of the bodies is driven/moved toward the alternate body for removal of the GET (15.sub.C). Embodiments of a ground engaging assembly are also disclosed.

A work tool or a wear member includes a working portion or a wear portion, a hollow portion that further defines a lock receiving aperture defining an axis of rotation, a radial direction, and a circumferential direction. The axis of rotation is transverse to the direction of assembly of work tool or wear member as the member is slid over a nose portion of a tool adaptor or the like. The axis of rotation is spaced away from the direction the pin receiving thru-hole extends a predetermined distance measured along the direction of assembly.

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.

A ground engaging tip of a ground engaging tip assembly includes an adapter configured for attachment to the base edge of the implement and having a forwardly extending adapter nose. The ground engaging tip has a rear edge, a top outer surface, and a bottom outer surface. The top and bottom outer surfaces extend forward from the rear edge and converge at a front edge of the ground engaging tip. The tip has first and second side outer surfaces extending forward from the rear edge of the ground engaging tip to the front edge. The tip has a nose cavity for receiving the adapter nose therein. The tip has a support rib 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.

A tool bit comprises a shank portion defining a longitudinal axis; and a working portion. The working portion includes at least a first arcuate surface disposed longitudinally adjacent the shank portion.

Provided is an arrangement that attaches a ground-engaging tool (GET) to an adapter on support structure of ground/earth engaging/conditioning apparatus. A retainer is in a recess of the adapter. A fastener is received through the GET aperture and into the adapter aperture. The head of the fastener can be within a recess of the GET. The recess can be multi lobed/shaped to receive the retainer and prevent rotation or other torsional/lateral deformation of the retainer when tightening/inserting the fastener. A fastener has a first threaded portion adjacent the head of the fastener and a second threaded portion along a shaft portion of the fastener extending distal from the head. The first threaded portion can be wider and/or of a more coarse thread pitch than the second threaded portion.
