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.

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 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.

A stabilizer structure includes an elongated main body portion having an upper portion with outward-facing side surfaces and a lower portion below the upper portion, the lower portion being greater in width than the upper portion. The stabilizer structure also includes a hole in a top surface of the upper portion. The stabilizer also includes a forward portion integrated with the main body portion as a single monolithic piece. The forward portion includes a bridge section, a first prong extending from the bridge section, and a second prong extending from the bridge section. The first prong, second prong, and bridge section share a single forward-facing curved surface and a single rear-facing curved surface, the forward-facing curved surface having a different curve than the rear-facing curved surface.

A ground engaging tip of a ground engaging tip assembly includes an adapter that attaches to the base edge and having a forwardly extending adapter nose, and a ground engaging tip. The tip has a rear edge and a top and bottom outer surfaces. The top and bottom outer surfaces extend forward from the rear edge of the ground engaging tip and converge at a front edge of the tip. The tip includes first and second side outer surfaces extending forward from the rear edge to the front edge. Tip includes a nose cavity for receiving the adapter nose therein. The nose cavity has first and second side inner surfaces opposite the first and second side outer surfaces, respectively. The nose cavity has an aperture and a retention channel on at least one of the first and second side inner surfaces. The retention channel extends from the rear edge to the aperture and guides a lug of the adapter into the aperture during installation of the ground engaging tip on the adapter. The retention channel has an untapered portion and a tapered portion, with the tapered portion extending from the rear edge to the untapered portion and the untapered portion extending from the tapered portion to the aperture.

An adapter board defines an upper adapter board attachment portion, and a lower tool bit attachment portion. The upper adapter board attachment portion includes a first peak surface and a second peak surface, the first peak surface and the second peak surface forming a first valley between the first peak surface and the second peak surface.

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.

An excavating system for use in ground-engaging applications. The excavating system may include a wear member having a top leg, a bottom leg, and a bearing face connecting the legs. The excavating system may also include a lip, which may include a top inset surface. The top inset surface may have an upper bearing surface shaped to bear against an inner surface of the top leg of the shroud. The top inset surface may also have a forward bearing surface extending between the upper bearing surface and a lower surface formed on the downwardly facing surface. The forward bearing surface may face upwardly and forwardly at a non-vertical angle.

A fastening assembly may comprise a collar and a pin. The collar may have an aperture, a collar lock, which projects from an outer surface, and a pin lock, which is disposed on a portion of the aperture. The collar lock may be compressible and configured to elastically deform while introducing the collar to a wear member. The pin may have a pin lock engagement hole shaped to engage with the pin lock as it is inserted through the aperture of the collar. The fastening system may be used in a wear member assembly. The wear member may have a side opening in communication with a cavity formed on one end of the wear member. The side opening may have a collar lock engagement hole. The collar may be inserted into the side opening so that the collar lock engages the collar lock engagement hole. Methods and assemblies thereof.

A monitoring device and system located in a hole in a base of a ground engaging product for monitoring a characteristic of the ground engaging product. The characteristic can pertain to presence, part ID, condition, usage and/or performance of ground-engaging product secured to the earth working equipment. The monitoring system may detect the presence and/or absence of one or more of the components of the ground engaging product.
