An abutment assembly for reacting forces applied to a wear component attached to a lip of a material handling implement can include a base configured to be rigidly secured to the lip, and an abutment displaceable relative to the base and configured to contact a surface of the wear component. A method of securing a wear component on a material handling implement can include rigidly attaching a base of an abutment assembly to the lip, positioning the wear component on the lip, and then displacing an abutment of the abutment assembly relative to the base. The displacing step can include the abutment contacting a surface of the wear component.

A system for use in securing bits against rotation in a motor grader may include a bit, with the bit having a shank. The shank may include a locking portion. The system may include an adapter board including a hole configured to receive the shank of the bit. The system may also include an anti-rotation plate configured to engage the locking portion of the shank of the bit such that the anti-rotation plate constrains the bit against rotation with respect to the adapter board.

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.

Wear caps protect the wearable surfaces of an adapter for an earth working equipment. These wear caps are subjected to erosion and wear by contact with abrasive material, such as experienced in an excavating operation. The wear caps can be attached to upper and lower legs of the adapter and protect them from wear. Each wear cap is secured to a retention feature on an independent mounting structure. The independent mounting structures are aligned and staggered such that installation of a wear cap onto the rearward independent mounting structure is conducted first. The independent mounting structures on an upper leg may be situated one above the other.

A locking pin assembly for securing a wear member to a support structure may include a body portion and may include a shaft member partially disposed within and extending from the body portion and rotatable between a first position that mechanically inhibits removal of a ground engaging member from a support structure and a second position that permits removal of the ground engaging member from the support structure. A wear member for receiving a locking pin assembly may include a bore extending laterally through the bore member with a proximal opening and a distal opening, an installation ramp and a removal ramp may be disposed at the proximal opening for engaging a tang of a shaft member of the locking pin assembly.

A construction machinery bucket part includes a body including a low alloy cast iron, and a wear resistant tip cast bonded to an end portion of the body and including a white cast iron. The construction machinery bucket part includes dissimilar materials, and has improved economic feasibility and wear resistance.

A bucket tooth adapter for a bucket includes a mounting portion and a nose portion extending from the mounting portion. The mounting portion includes a first body portion and a wide portion. The wide portion is wider than the first body portion and is provided between the first body portion and the nose portion.

An adapter cover includes a front face portion that defines a thru-hole configured to allow a nose portion of an adapter to pass horizontally through the thru-hole past the interior surface and then past the exterior surface, and a top single leg extends horizontally from the front face portion. The thru-hole defines a perimeter with a right side edge, a left side edge, a top edge, an upper right corner and an upper left corner, and further defines a bottom open end.

A retaining spring clip includes an elongated body defining a longitudinal direction, a lateral direction that is perpendicular to the longitudinal direction, and a transverse direction that is perpendicular to the lateral direction and the longitudinal direction. A handle is disposed proximate to a first longitudinal end, an intermediate spring is disposed along the longitudinal direction, and a stepped groove is disposed proximate to a second longitudinal end. A triangular shaped void forms a backside of the intermediate spring, and a void filler is disposed in the triangular shaped void.

A tapered bushing includes a conical inner surface defining a conical axis, and a radial direction. The tapered bushing further includes an outer surface of revolution, and defines a minimum radial wall thickness that ranges from 3.0 mm to 15.0 mm measured from the conical inner surface to the outer surface of revolution. Also, the conical inner surface defines a draft angle that ranges from 2.0 degrees to 30.0 degrees.
