<p>A two-part locking pin for a mining bucket tooth retaining attachment includes a rotating part (300) having a hexagonal nut (306) and a threaded shaft (304) adapted to connect to an insertion part (200) having a keyway (202) and a seat groove (204). The locking pin is inserted in a through hole which is adjacent to a communicating engagement member hole, the engagement member having teeth (404, 406) which project into the locking member hole, so the locking member can only be inserted when the keyway is aligned with the projecting teeth. Slots on the locking member permit the locking member to be rotated so the teeth align with the seat. The teeth are located near a neutral load axis.</p> |
