Abstract: A retention mechanism may have a pin inserted into a retainer pin opening in the adapter. The retention mechanism may also have a spring clip inserted into the tip through a first end of a transverse hole in the tip, and a retainer inserted through a second end of the transverse hole. The retainer may have a retainer body extending from a first axial end to a second axial end. The retainer may have at least one tab extending radially from the retainer body at the first axial end. The at least one tab may engage with a female thread in the transverse hole. The retainer may have at least one detent cutout disposed on an outer surface of the retainer body for receiving a portion of the spring clip. The retainer may also have an axial cavity at the second axial end for receiving one end of the pin.

Abstract: A retention mechanism for connecting a tip to an adapter may have a main retainer, a center pin, and a center pin clip attachable to the center pin. The main retainer may have a retainer body, a non-circular thru hole extending along a central axis, and a male thread around an outer surface of the main retainer. The male thread may engage a female thread in a transverse thru hole in the tip. The center pin may have a profile matching that of the non-circular thru hole of the main retainer. The non-circular thru hole of the main retainer may align with a non-circular blind hole in the adapter when in its fully engaged position. The center pin may be inserted into the non-circular thru hole of the main retainer with a distal end of the center pin positioned in the non-circular blind hole in the adapter.

Abstract: A retention mechanism for connecting a ground engaging tip and an adapter has a spring, a retainer block configured for insertion into a cutout in the adapter, and a retainer. The retainer block has a cavity having an internal thread. The retainer block also has an outer surface defining a contact surface, a back surface opposite the contact surface, and a plurality of angled surfaces between the contact surface and the back surface. Further, the retainer block has a slot passing through the back surface and configured to receive the spring. The retainer is configured for insertion in in the cavity of the retainer block. The retainer has a threaded outer surface configured to engage with the internal thread of the retainer block, a detent cutout configured to receive a portion of the spring, and a chamfered bottom surface configured to engage with and deflect the portion of the spring.

Abstract: A ground engaging tip assembly includes a ground engaging tip, an adapter, and a retention mechanism. The ground engaging tip includes an inner surface extending inward from a rear edge defining a nose cavity within the ground engaging tip. The nose cavity includes a front inner surface, top inner surface, bottom inner surface, and oppositely disposed side inner surfaces. The top inner surface includes a front portion proximate the front inner surface comprising a front central surface connecting two opposing front side-sloping surfaces and a rear portion proximate the rear edge comprising a rear central surface connecting two opposing rear side-sloping surfaces. The bottom includes a tapered bottom channel. The adapter includes a nose portion configured to be inserted into the nose cavity of the ground engaging tip. The retention mechanism is configured to secure the ground engaging tip to the adapter.

Abstract: The top cover defines a first fastener receiving void that is disposed along the direction of material flow between the forward ramp portion and the rear edge. The top male angled surface of the top cover defines a first material flow groove that extends along the direction of material flow, and includes a first flow ramp. The first material flow groove is disposed adjacent along the lateral direction and the direction of material flow to the first fastener receiving void.

Abstract: A cutting edge tip includes an attachment portion defining an adapter receiving void. A working portion extends forwardly from the attachment portion. A first lateral end portion is disposed along the lateral direction, the first lateral end portion defining a first lateral end surface that jogs laterally. Also, a second lateral end portion is disposed along the lateral direction opposite of the first lateral end portion. The second lateral end portion also defines a second lateral end surface that jogs laterally.

Abstract: A wear member includes a forward working portion that is disposed along its longitudinal axis including a closed end, and a rear attachment portion that is disposed along the longitudinal axis including an open end with an exterior surface, and an interior surface. The interior surface defines an interior counterbore with a major diameter, and a minor diameter. A ratio of the major diameter to the minor diameter ranges from 1.8 to 2.2.

Abstract: A spring loaded retainer includes a lug receiving portion defining a first maximum outside dimension, the lug receiving portion also defining a lug receiving slot that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall. A drive portion defines a second maximum outside dimension, and a first flat is disposed on the outside of the lug receiving portion proximate to the first sidewall or the second sidewall.

Abstract: A lock assembly for attaching a wear member to a base includes a threaded retaining block with a C-spring attached to the retaining block that fits into an aperture of the base. A threaded lock pin fits into the aperture of the wear member, and the threaded aperture of the retaining block, retaining the wear member onto the base. The threaded lock pin engages the C-spring that prevents unintentional rotation of the threaded lock pin so that the threaded lock pin is trapped in the aperture of the wear member, preventing its unintentional removal.
