Abstract

An anchor for a wear assembly on an excavating bucket is disclosed. The excavator bucket lip has a base having a nose, and the wear assembly includes a wear member having a cavity in which the nose can be received, and an aperture extending between an outside surface of the wear member and the cavity, an internally toothed ring being located within the aperture; and a lock for releasably holding the wear member to the base. The lock includes an operable member and an externally toothed resilient ring, the resilient ring having a central aperture for engagement with the operable member. The operable member and resilient ring are jointly rotatable relative to the cavity and the internally toothed ring between a plurality of rotationally spaced locking positions where the lock secures the wear member to the base with varying tightness, and a release position rotationally spaced from the locking positions. The teeth of the internally toothed ring and the teeth of the resilient ring engage each other in each of the locking positions to reduce the loosening of the lock during use.
