摘要： 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.

摘要： 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.

摘要： A retainer includes a drive portion defining a drive portion outer diameter, and a lug receiving portion with a skirt 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. The skirt also defines a skirt outer diameter that is greater than the drive portion outer diameter. Also, the drive portion has a hook tab that extends from the drive portion and that is spaced away from the skirt a minimum distance.

摘要： An adapter includes a first leg, a second leg, and a throat portion that define a slot defining a direction of assembly onto a work implement assembly, a lateral direction that is perpendicular to the direction of assembly, and a vertical direction that is perpendicular to the direction of assembly and the lateral direction. The throat portion further includes a first throat side surface disposed along the lateral direction and a second throat side surface disposed on the opposite side of the throat portion along the lateral direction. The first throat side surface defines a first adapter cover receiving recess.
