I maybe should have added a little more to my reply. Yes, I have had those bolts work loose and the extension drop down. More common even is the rear extension under the beater to fail the hardware. Combines, 7700,7720 and 8820, running high yielding corn, a more common failure. But, grade 8 bolts with lock nuts cured the problem. The wires will easily move around if not retained.
