Securing the Front Sprocket

I was cleaning my chain this evening when I happened to play with the bolt holding the front sprocket in place. Itís loose! The only thing that has been saving my life since who knows how long, is the washer youíre meant to fold over the bolt. Ultimately, I guess I did a good enough job folding it over, but it certainly doesnít look the way the factory had it.

I used a flathead and hammer to bend the washer. Any better ideas/tools out there? Iím going to tighten this bolt of course, but Iíll need a new washer first.Click image for larger version

Drill the nut and safety wire. Nothing like some added protection.

Sounds like a great idea to me!

Never had a problem on my bikes. I just tap the washer down with a screw driver or a punch so its flat.

My guess is that it was never tight to start with. That washer being folded over must have been saving my life for the past couple of months now.
