Abstract
A hammerless connector pin assembly is insertable in the aligned connector openings in telescoped excavation wear and support members and has associated locking structure for releasably locking the inserted assembly therein. The inserted assembly has opposite end portions that block removal of the wear member from the support member. One of such end portions has a laterally projecting cam member disposed thereon which is positioned within one of the wear member openings. As the interior surface of the wear member becomes worn from use and is able to shift further rearwardly along the support member, the cam member may be rotationally adjusted to maintain contact with the wear member to prevent forward movement thereof away from its rearward shifted position.
