    What tools are needed to remove freewheel cog?

    I think I need to replace my cog as it sounds like its lubricated with coarse sand but I'm uncertain as to what tools this would require as I've only removed cassettes in the past.

    A freewheel tool

    You need to bolt the tool on somewhat loosely. You'll probably need a longer bolt than you use to bolt the wheel into the dropouts. Then clamp it into a vice, or have a long cheater bar of some kind. My tool has a female end (heh-heh) for a 3/8" ratchet, and a 1" hex outside. If you try to use a 3/8" ratchet, you'll break it for sure; probably even a 3/8" breaker bar. I use a 1" socket on an old bulletproof craftsman 1/2" ratchet and a 6' piece of muffler pipe as a cheater bar. I hold the tire and the socket onto the FW tool and have one of my kids hang on the pipe and it comes loose very nicely. That's 600 ft-lbs of torque.

    It's not going to be easy to get off. Maybe buy the tool at the LBS and talk them into doing it for you the first time and watch how they do it.

    This should be in the FAQ, but I didn't see it.

    Thanks guys. I have a cheater bar that should work but I need to get the freewheel tool first. Just wanted to make sure there wasn't anthing else special that I needed.

    Use a vise

    Cheater bars are too difficult to keep aligned. Clamp the tool in a vise, push down very hard on the wheel while you turn it. Thre rim makes it easy to keep flat and gives you two points opposite each other to turn from. If you mash the tool or the freewheel by using a sloppy bar on a ratchet that doesnt fit properly, you will have to sacrifice the entire mess and clamp the remains in a vise anyway....
