A bucket lip for an excavator

A method of installing a wear member on a lip of an excavator wherein the lip has a through-hole and a boss on each side of the lip includes the steps of placing a wear member including a pair of rearwardly extending legs, each of the legs having a longitudinal slot and a transverse opening, on a lip such that the legs straddle the lip; moving the wear member rearward relative to the lip such that each boss moves axially into one of the slots until reaching a mounting position where the opening in the wear member is generally aligned with the through-hole in the lip; and placing a lock into the opening and the through-hole. Also disclosed is a boss to be fixed to a lip of an excavating bucket for supporting a wear member attached to the lip. The boss comprises a main body to be received in a slot of the wear member, the main body having an inner surface to set against a face of the lip and a pair of opposite sidewalls; and a stem extending generally outward from the inner surface to fit within a hole in the lip.
