Greg,
I can't imagine why you would be having this problem. There is not
supposed to be much weight or tension on that part and certainly not
enough to cause the bolt to shear.
I would start by looking to see if something is pressing on the air
cleaner. Perhaps the bonnet is not clearing and exerting pressure on
it.
Good Luck,
Joe Curry
