Abstract
A wear runner assembly includes a base which is representatively secured to an excavating bucket wall surface, and a wear runner which is releasably connectable to the base by moving the wear runner in a locking direction parallel to the surface to engage tongues on the base with grooves on the wear runner and thereby prevent removal of the wear runner from the base in a removal direction transverse to the surface and the locking direction. By moving the wear runner relative to the base in an unlocking direction opposite to the locking direction the connected wear runner may then be moved in the removal direction to separate the wear runner from the base. To prevent movement of the wear runner in this unlocking direction and corresponding uncoupling of the wear runner from the base, a generally cylindrical locking pin member is inserted in aligned openings in the wear runner and the base and rotated about an axis parallel to the removal direction to cause thread-like external projections on the locking pin to enter corresponding grooves in the base to prevent shifting of the wear runner relative to the base in the unlocking direction. As the locking pin is rotated into place it causes a resilient detent pin structure on the base to snap into a corresponding depression on the pin to releasably prevent the pin from being rotationally backed out of the aligned base and wear member openings.
