WEAR ASSEMBLY FOR USE ON EARTH WORKING EQUIPMENT
A wear assembly for excavating equipment which includes a wear member and a base each with upper and lower stabilizing surfaces that are offset and at overlapping depths to reduce the overall depth of the assembly while maintaining high strength and a stable coupling. The nose and socket each includes a generally triangular-shaped front stabilizing end to provide a highly stable front connection between the nose and wear member for both vertical and side loading. The lock is movable between hold and release positions to accommodate replacing of the wear member when needed, and secured to the wear member for shipping and storage purposes.

42 . A wear assembly for excavating equipment comprising:
a wear member including an exterior surface, a front end facing generally in the direction of travel during excavating, a rear mounting end including a cavity having opposing upper and lower walls, sidewalls extending between the upper and lower walls along the length of the cavity, and a front wall extending between the upper and lower walls at a front end of the cavity, the cavity opening rearward to receive a base of the excavating equipment between the upper and lower walls and between the sidewalls for supporting the wear member on the excavating equipment, and a through-hole extending from the exterior surface to the cavity and opening in one of the sidewalls; and
a lock secured to the wear member in the through-hole, the lock being adjustable between a hold position and a release position where the lock in the hold position holds the wear member to the base and in the release position permits installation of the wear member onto the base, and the lock being secured to the wear member in both the hold position and the release position irrespective of the insertion of the base into the cavity or the orientation of the wear member to form a single integral component with less risk the lock will be separate from the wear member and lost.
43 . A wear assembly in accordance with claim 42 wherein the lock is includes a tool-receiving formation to receive a tool to adjust the lock between the hold position and the release position without the use of threads and without the use of a hammer.
44 . A wear assembly in accordance with claim 43 wherein the lock includes a latch to retain the lock in each of the hold and release positions with each said position being in a pre-established location.
45 . A wear assembly in accordance with claim 44 wherein the lock includes a body to interact with the base in the hold position to hold the wear member to the base when installed and to permit installation of the wear member on the base in the release position, and a resilient member to resist adjustment of the lock between the hold and release positions.
46 . A wear assembly in accordance with claim 42 wherein the lock includes a tool-receiving formation operable to receive a tool to adjust the lock between the hold position and the release position without a hammer.
47 . A wear assembly in accordance with claim 46 wherein the lock includes a latch to retain the lock in each of the hold and release positions with each said position being in a pre-established location.
48 . A wear assembly in accordance with claim 47 wherein the lock includes a body to interact with the base in the hold position to hold the wear member to the base when received in the cavity and to permit installation of the wear member on the base, and a resilient member to resist adjustment of the lock between the hold and release positions.
49 . A wear assembly in accordance with claim 48 wherein the body is movable about an axis between the hold and release positions.
50 . A wear assembly in accordance with claim 49 wherein the axis extends generally in the same direction the base is received into the cavity.
51 . A wear assembly in accordance with claim 42 wherein the lock includes a body to interact with the base in the hold position to hold the wear member to the base when installed and to permit installation of the wear member on the base in the release position, and a resilient member to resist adjustment of the lock between the hold and release positions.
52 . A wear assembly in accordance with claim 51 wherein the lock includes a latch to retain the lock in each of the hold and release positions with each said position being in a pre-established location.
53 . A wear assembly in accordance with claim 42 wherein the lock includes a latch to retain the lock in each of the hold and release positions with each said position being in a pre-established location.
54 . A wear assembly in accordance with claim 42 wherein the lock is integrally secured to the wear member for shipping and storage as a single integral component.
55 . A wear assembly in accordance with claim 42 wherein the lock is secured to the wear member such that they are maintained as a single integral component through shipping, storage, installation and use.
56 . A wear assembly in accordance with claim 42 wherein the wear member is a point with a front digging edge.
