Abstract:
1. A wear assembly for an excavating bucket comprising: a base located on a lip of the excavator bucket, the base having a nose; 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 including 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 being 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, wherein 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, and wherein the teeth of the resilient member flex to permit rotation of the operable member when the operable member is turned by an operator.
