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.

A work tool or a wear member includes a working portion or a wear portion, and a shank extending from the working portion or the wear portion, defining a longitudinal axis, and a first lock receiving groove that defines an axis of rotation that is perpendicular to the longitudinal axis of the shank.

A retainer for attaching a work member or a wear member to an implement of a machine includes a wavy annular body defining a central axis, and at least one detent. A tab extends axially away from the wavy annular body.

A retaining system includes a lock including a drive portion that defines an axis of rotation, a radial direction, and a circumferential direction, and further includes a locking portion including an outer peripheral surface. A wing extends radially outwardly from the outer peripheral surface, while the locking portion is connected to the drive portion by a wall. A rib extends axially from the wall toward the drive portion forming an annular cavity, defining at least one detent receiving aperture that is disposed in the annular cavity.

A system and tool for monitoring ground-engaging products for earth working equipment that can monitor characteristics such as part identification, presence, condition, usage, and/or performance of the products on earth working equipment used, for example, in mining, construction, and dredging environments. The monitoring tool includes or is supported by a mobile device that is separate from the earth working equipment. Supporting the monitoring tool on a mobile device can, e.g., provide unique vantage points to monitor the earth working equipment products, monitor the products without inhibiting the operation of the earth working equipment or endangering personnel, closely approach areas of interest for secure and reliable gathering of information, monitor multiple earth working equipment, and/or be protected from the vibrations and impact shocks that can be associated with earth working equipment.

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 work tool or a wear member includes a working portion or a wear portion, and a shank extending from the working portion or the wear portion, defining a longitudinal axis, and a first lock receiving groove that defines an axis of rotation that is perpendicular to the longitudinal axis of the shank.

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 spring clip defines an axis of movement, and includes a handle portion disposed at a first end along the axis of movement, and a tool bit engaging portion disposed at a second end along the axis of movement. Also, an adapter board engaging portion is disposed at least partially between the handle portion, and the tool bit engaging portion along the axis of movement.

An adapter board has an upper moldboard interfacing portion including a rear flat surface, a front surface, and a plurality of retaining spring clip receiving apertures extending from the front surface to the rear flat surface. A lower tool bit attachment portion of the adapter board terminates in a lower adapter board free end defining a bottom surface that defines a plurality of shank receiving bores. Each one of the plurality of shank receiving bores is in communication with one of the plurality of retaining spring clip receiving apertures.
