Abstract: A retainer sleeve configured for use in a retainer system for a ground engaging tool includes a plurality of plate-like sections, each section being flexibly joined with an adjacent section along either a radially inner edge or a portion of a radially outer edge. The radially inner edges of the plurality of sections form part of a segmented inner surface configured for engagement with an outer surface of a locking member of the retainer system. The inner surface extends partially around a central axis of the retainer sleeve to form a substantially C-shaped retainer sleeve having opposite circumferential ends that are spaced from each other. The radially outer edges of the plurality of sections form part of a segmented, frustoconical outer surface configured for engagement in an internal lock cavity of a ground engaging tool tip.

Abstract: A wear indicator is provided for a wear member of a machine wherein the wear member is subject to wear during use of the machine. The wear indicator may include a plug member configured to be positioned in a region of the wear member subject to wear. The plug member may be oriented with a central axis extending in a direction substantially parallel to a direction of wear of the wear member. The wear indicator may include a plurality of perceptibly different and distinct axial cross sections taken perpendicular to the central axis of the plug member in axially spaced planes along the central axis.

Abstract: A mounting base for removably coupling a wear member to a tool may have a generally planar first base portion, which may have an inward surface configured to be attached to the tool. The mounting base may also have a generally planar second base portion extending from the first base portion in a direction generally perpendicular to the first base portion. The second base portion may have an inward surface configured to be attached to the tool. The first base portion may define an opening including a notch-shaped portion and a rectangle-shaped portion.

Abstract: A wear member for a tool may have a generally planar first wear member portion defining an opening. The first wear member portion may also have a first inward surface defining a projection adjacent the opening for removably coupling the wear member to a mounting base attached to the tool. The wear member may also have a generally planar second wear member portion extending from the first wear member portion in a direction generally perpendicular to the first wear member portion. The second wear member portion may also have a second inward surface contiguous with the first inward surface. The first and second inward surfaces may define a receiving pocket configured to receive the mounting base, and the projection may be positioned completely within the receiving pocket.

Abstract translation: 用于工具的磨损构件可以具有限定开口的大致平面的第一磨损构件部分。 第一磨损构件部分还可以具有限定邻近开口的突起的第一向内表面，用于将耐磨构件可移除地联接到附接到工具的安装基座。 磨损构件还可以具有大致平坦的第二磨损构件部分，其从大致垂直于第一磨损构件部分的方向从第一磨损构件部分延伸。 第二磨损构件部分还可以具有与第一向内表面邻接的第二内表面。 第一和第二内表面可以限定构造成接收安装基座的接收凹部，并且突出部可以完全定位在接收口袋内。
