ABSTRACT:
A wear assembly for attaching wear members to a lip of an excavator includes a wear member, a boss and a lock. The lip includes an inner face, an outer face, a digging edge and a series of through-holes spaced rearward of the digging edge. The bosses are each fixed to a face of the lip at a position rearward of the through-holes. The wear members each include slots to receive the boss adjacent their rear ends, and openings for receiving the locks at a position forward of the bosses. The openings are aligned with the through-holes in the lip. The lock includes a wedge and spool arrangement.
