Abstract
Disclosed are various exemplary embodiments of a retainer bushing for use with a lock in a ground engaging tool. The retainer bushing may include a skirt extending around a retainer axis, where the skirt may include an outer surface configured to mate with a lock cavity of the ground engaging tool and an inner surface configured to rotatably receive an outer surface of the lock. The retainer bushing may also include a detent projection extending radially inward from the inner surface with respect to the retainer axis and configured to engage a detent recess of the lock to releasably hold the lock. The detent projection may include a convex surface with a substantially constant radius, and a center of the radius of the convex surface may be positioned at a first distance from the retainer axis that is greater than a second distance between the retainer axis and the outer surface of the skirt.
