Abstract: 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.

Abstract: 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.

Abstract: A shroud for a work tool is disclosed. The shroud may have a tip portion. The tip portion may have a tip extending from a shroud proximal end to a tip end disposed between the shroud proximal end and a shroud distal end. The tip portion may further have an upper leg extending from the tip end to an upper leg distal end. The tip portion may also have a lower leg extending from the tip end to a lower leg distal end. The lower leg may be spaced apart from the upper leg to form an opening between the upper leg and the lower leg. The shroud may have an attachment portion attached to the upper leg. The attachment portion may extend from adjacent the tip end to the shroud distal end.
