Abstract
A wear assembly for use on various kinds of earth working equipment that includes a base with a supporting portion, a wear member with a cavity into which the supporting portion is received, and a lock to releasably secure the wear member to the base. The supporting portion is formed with top and bottom recesses that receive complementary projections of the wear member. These recesses and projections include aligned holes so as to receive and position the lock centrally within the wear assembly and remote from the wear surface. The hole in the wear member is defined by a wall that includes a retaining structure provided with an upper bearing surface and a lower bearing surface for contacting and retaining the lock against upward and downward movement in the hole. The lock includes a mounting component that defines a threaded opening for receiving a threaded pin that is used to releasably hold the wear member to the base. The separate mounting component can be easily manufactured and secured within the wear member for less expense and higher quality than forming the threads directly in the wear member.
