Yamaha ATV Stripped Bolt

What's the best way to get a stripped hex bolt out of the gear box rear end on a 2013 Yamaha Grizzly?

John Talley: There are a couple of different techniques for this. And it’s a little bit barbaric, but what I’ve done in the past is either, if it’s a metric 6, then I would go to a standard 5/16th.

Garrett Sifford: Basically go up one size.

John Talley: Go up one size and just hammer it in there with a bit you don’t care about, because it’s going to damage it. Typically that, or going to a Torx type bit. A bigger Torx, driving it in there and basically creating a new surface for it to grab on. And then when you actually get it driven in there, use an impact screwdriver to pop it loose. Now hopefully the combination of those two will get it out of there for you.

Garrett Sifford: They also make some easy-outs too, that are kind of cylindrical and you can tap them into place. I’ve used those to get out bolts before. And if all that fails, another thing you can try, which is really barbaric, but break out your Dremel tool and grind a flat spot into the bolt and then get a really large flathead screw on that impact driver.

John Talley: One more. Cut a notch in it to the outside, and then use a chisel and try to turn it that way.
