cog removal ideas pls

  • Any ideas how to get this off ? Got this in a poor state, already ruined my chain whip. Have tryed hammer and screw driver and destroyed two teeth only one left. (There was only 3 on there when I got it.

  • Will a chain hold on the teeth?

    Try the old chain around the bottom bracket trick.

  • Rotafix the shit out of it

  • re attach wheel to bike and try skidding a few times with a sticky tyre
    thats how most peoples cogs come loose albeit unintentionally

  • cheers rice lost bit of skin on some fingers but yes it worked cheers.

  • plenty of life left in that cog.

  • If you can grip the cog in a large well secured vice it may well undo, some heat on the cog will help but let the cog get cold before you try to undo it. Aluminium expands more than steel so at first the cog will be on tighter hence let it cool. Try turning the wheel a bit to tighten the cog first as well. Put some lubricant on the threads, if you can get it some diesel fuel will do. Other than that it may well be a very careful job with a Dremel or similar to cut away the cog enough to break it across the threaded part.

  • Sorry just seen this!

    Glad it worked.
