    shimano freewheel removal

    I fitted a shimano 16t freewheel sprocket to to my hope hub a good few years ago, I just tightened it by hand from what I remember, but how do I get it off? I dont see any teeth or cut outs for a tool to fit it, any ideas?

    Hopefully you used anti-seize or at least grease on the threads...

    ...ummm...Hope non-cassette hub? Did they make any?

    more power! ungh!! ungh!!! an impact wrench mated to a freewheel removal tool will do the trick.
    I gotta roll, can't stand still, got a flame in my heart, can't get my fill.

    Will require something like this to remove it:

    Remember, a 100lb GF on the end of a 5' pipe can generate 500 ft lbs of torque. Leave a tire on it, inflated, bolt the tool onto the hub and use a long cheater pipe. Sometimes I can do it myself, but it helps to have a helper.

    If you've got something else, never mind.

    If it really is a non-cassette hub and a regular Shimano freewheel then try this.

    I use a freewheel removal tool, a wrench with a roundish handle, and a length of plumber's pipe from the hardware store. Holding the freewheel removal tool onto the freewheel is key. I had a Surly hub so I was able to use the threaded axle and "bolt" the removal tool on to keep it from sliding off and rounding off the teeth that the FW removal tool mates to.

    Once I got the tool secure to the freewheel, I just let the lever work its magic. Hardly any force is necessary with 4 feet of pipe working for you. Just be sure to back off the bolt holding (the one holding the removal tool to the FW) right away so the FW has somewhere to go. Oh, and be sure you turn everything the right direction.

    Not saying that this is the best way, but it works for me.

    Bang on, I knew there would be a tool to fetch it off, but I've had a look on a few sites and I cant seem to find one, thanks for thal link I'll get on it.

    Yeah hope made a non cassette single speed hub, I'll get some pics when the cogs off, doesnt feel very free anymore though, I wonder if the parts are still around to service it, its about 8-9 years old.

    Thanks for the help!

    you should be able to find a Park FR-6 on any of a dozen web retailers or your lbs. Especially if they sell BMX stuff.

    what I find truly amazing is that a shimano fw could last "a good few years"!!!

    You really threw me off when you wrote this:

    The "cut outs" are very obvious to me and the normal design for BMX FWs

    You're right, it is obvious when you know what the removal tool looks like, all I'd found was one with multiple teeth on similar to a BB removal tool, hence I couldnt see multiple slots for said teeth to fit, having no experience of BMX I didnt know there was a specific tool for this job.

    I managed to find one on ebay, only trouble is I tried it this morning and it doesnt fit over the hub! its slightly to small so I might try running a drill through it when I get chance. someone somewhere doesnt want me taking this bike apart

    I'm curious as to the thread direction. Is it standard or reverse?

    EDIT: I figured it out, it's standard thread. All I needed was a little penatrating spray to loosen the bond and the cheater pipe worked great. An 1 1/4 socket fits perfectly over the ACS fw tool, if that helps anyone...
