Shear bolts ,snowthrower

Had the occasion today to winterize/summarize my snow thrower. On checking the bolts
I found one was bent,and very difficult to remove.

I'm wondering if i tightened the pin too tightly? I really snugged the pin bolt

They normally only need to be snugged. You want it tight enough that the nut doesn't come loose but other than that it's not holding anything so it doesn't need to be tightened really hard. Still, over tightening will not bend a bolt. You probably hit something which was enough to bend the bolt but not shear it in half.

Are you sure it was a bonified shear bolt? It should not take much to shear those. It's meant to do that. Could it be that someone or you may have installed a regular bolt by mistake or as a quick fix?

The shear bolts were the originals on the machine. I guess the answer might be closer to pilot

Dan's theory.

Thanks for your inputs
