- 12. A lock mechanism for preventing unwanted rotation of a jam nut that is mounted on an externally threaded end portion of a connecting rod and abuts against a rod end having an internally threaded bore in which the end portion of the connecting rod is threadedly received, the lock mechanism comprising a lock collar which is slidably mounted on and constrained against rotation relative to the rod end for movement between a retracted position out of contact with the jam nut and a locking position in which the collar peripherally engages the jam nut and prevents the jam nut from turning, and a retainer for keeping the lock collar in the locking position.
