Yesterday, another bolt loosened on my spare tire power hammer. The bolt serves as a retaining pin and it’s threads have fretted away. There are two set of pins so it has never gone far enough to develop into a real safety problem, but it is a nuisance.
A few months ago this happened on one bolt in the front pair so I removed them and welded on small square nuts, replaced them with the usual coating of black silicone caulk and passed a wire through the nut holes and loosely tightened it. The bolts have stayed in place since then.
It was one of the back pair that jumped out yesterday so I did the same thing, welded the nuts and passed the wire. I haven't had time to take another image with Thanksgiving preparations and the image I took of the first fix is a poor one. Still, I think, this is enough to get the idea across.
