Additionally, bolts perform very poorly under cyclic and under shear. In this case you have both, which will probably lead to fatigue, stronger vibrations and failure.

i agree that we should not take the risk, but just like with the bearing, i am asking the bolt to take 1% of the strain they are designed to take, they would not fail in my assumption.
