The clevis includes a plurality of arcuate, lip-like, outwardly-radially-projecting first retention members and the structure includes a cap portion having a plurality of arcuate, lip-like, inwardly-radially-projecting second retention members. Each second retention member engages and "locks" to a separate first retention member. The cap portion, which interferes with free axial travel of the pin, is well secured so that the pin is retained in engagement with the clevis without welding the pin. Avoiding pin welding permits using a substantially-harder pin, resulting in significantly better wear characteristics. A new method for retaining a pin is also disclosed.
