Abstract: A lock assembly for attaching a wear member to a base includes a retaining block with a spring attached to the retaining block that fits into an aperture of the base. A lock pin fits into the aperture of the wear member, and the aperture of the retaining block, retaining the wear member onto the base. The lock pin engages the spring that prevents unintentional rotation of the lock pin so that the lock pin is trapped in the aperture of the wear member, preventing its unintentional removal.

Abstract: A retainer includes a drive portion defining a drive portion outer diameter, and a lug receiving portion with a skirt defining a lug receiving slot that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall. The skirt also defines a skirt outer diameter that is greater than the drive portion outer diameter. Also, the drive portion has a hook tab that extends from the drive portion and that is spaced away from the skirt a minimum distance.

Abstract: A tip and adapter assembly includes a spring loaded retainer that includes a lug receiving portion defining a first maximum outside dimension, the lug receiving portion also defining a lug receiving slot that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall. A drive portion defines a second maximum outside dimension, and a first flat is disposed on the outside of the lug receiving portion proximate to the first sidewall or the second sidewall.
