ABSTRACT:
A wear assembly that includes a wear member and a boss to define an opening for receiving a lock forward of the front edge face of the lip which can mount the wear member in a stable and balanced manner without a through-hole in the lip. The wear member includes an aperture and a rib to define bearing faces on opposite sides of a central plane of the lip. The boss includes rails to hold the wear member in place, and a brace at the rear end, which supports the rails on the boss, abuts the rear of the wear member to reduce the loading on the lip, and deflects earthen material away from the wear member under reverse loading.
