I have never run into a "lock washer" that looks like this...
How do you use this thing? It has some tabs that fit into a spline, that I understand. But the dished part? Not so much....
And what is the hole for?
To me a lock washer locks a nut or bolt down to keep it from backing off by bending tabs onto the flats.
Am I suppose to just beat the tar out of this thing to get it around the flats? Am I suppose to notch tabs into it? Is the hole for safety wire?????
Should I just toss it out and use a real lock washer...whats the deal with this thing?
Oh, and a picture of the bike.
