Image 2: Bottom View of 5 Wheel Locking Jaws When The Jaw Fork Is Not Fully Engaged
Note that you ARE NOT able to engage the road lock in this view. The jaw fork is not fully
engaged in the back of the king pin jaws although the king pin jaws are "locked" around the king
pin.Notice that the rod on the jaw fork extends past the square bar on the road lock. In this case, it
is possible for the jaw fork to be forcibly pushed out of the locked position with excessive pull or
a side load on the king pin jaws. This is especially true if other components in the assembly are
weak, malfunctioning, broken, or missing. The pictures below are actual images of this condition.
Note that you could hear the "snap" of the jaw around the king pin (see below), but this unit was
not securely locked!
