Abstract: In at least one embodiment, a wear assembly (1) includes a wear member (10, 100, 110) to be mounted to an implement or apparatus to be protected, a base member (30, 300, 330) to be attached to the implement or apparatus, a lock member (20, 21) to lock the wear member (10, 100, 110) to the base member (30, 300, 330), the wear member (10, 100, 110) including or receiving the lock member (20, 21) and the base (30, 300, 330) including at least one aperture (33) in which is located a releasable retaining means (40) to releasably hold a portion (22) of the lock member (20, 21). The wear member can be: shroud; a tile shroud; a tooth; a replaceable tip. The base member can be: a base for a shroud, a base for a tile shroud; an adaptor for a tooth; an adaptor for a replaceable tip. The implement or apparatus can be: an excavation bucket; a grader blade; a chute; an excavation bucket edge; an excavation bucket surface; dump or haul truck load carrier; an earth, ore or mineral handling apparatus.

Abstract: In at least one embodiment, a pair of components includes a tooth and adaptor for an earth-moving apparatus. The adaptor is for mounting the tooth on an earth-moving bucket, this mounting being releasable to allow replacement of the tooth when worn. The components define aligned passages through which a locking pin extends to retain the components together. The locking pin has formations for engaging formations on the first component when the pin is rotated from a free position into a locked position. The pin has an insertion recess which is aligned with the formations allowing the pin, in the free position, to be inserted into, or removed from, the aligned passages. The formations are resiliently movable to stably engage the pin when in the locked position.
