    Anyone seen a nut like this before?

    In the middle of doing a 530 conversion on my '82 1000 kat and got stuck at trying to undo the nut on the front sprocket. I've tried my impact wrench and applying a 4ft wrecking bar to the 32mm socket at which point I started to lift the machine from it's stand and it still didn't let go.

    Looking at the nut before I started, it looked like there may be some kind of retention clip visible between the internal face of the nut and output shaft. If you look closely you'll see kind of a slot either side of the shaft in what looks to me like a spring clip kind of deal. I've never seen a nut like this before, has anyone else?

    Not sure whether to keep working at it or whether there's some "trick" to this kind of nut.

    Any body seen anything like this before?

    It's smoke that make electronic components work.
    Every time I've let the smoke out by mistake, they never work again.

      No retention clip...just the bendable locking washer, which it looks like you unbended...

      The impact should do it, always worked for me..

        With the picture, I can tell you that it is in fact a form of lock-nut.
        I would use it and the folding washer to retain the sprocket.

            Agree with Eric, looks like the stock locknut.

              HA! I win...

              It's off

              Took a ton of hammering with my impact gun but it let go in the end.

              Thanks for the confirmation the nut was nothing special. Had visions of going too hard and nadging up the output shaft or something else equally undesirable.

              Onward with the conversion..... hooray! Unlikely to be finished today now like I was hoping though

                Looks just like one I was describing out in the garage.

                I suspect you could use a bigger impact gun.

                    Keep a 3/4" gun around the house. They take EVERYTHING off!
