    Freewheel Help Needed

    I have a complicated freewheel situation.

    I have a 18t Shimano freewheel that is removed from the hub with a two prong freewheel removal tool. This freewheel requires the track / bmx style chain (1/8 I believe) as opposed to the freewheels that require the four prong freewheel removal tool and use a 3/32 chain. I have this freewheel installed on a Paul Word disc hub.

    Now to the problem. I was attempting to remove the Shimano freewheel from the hub and the "lip" on the freewheel that the two pronged removal tool sits in actually broke off. I had the removal tool in a bench vise and as I rotated the wheel there was a loud pop and when I inspected the wheel I saw that the lip had been destoyed.

    I can see no way to get the freewheel off the hub now that this has happened. I have attempted to lock the wheel in the vise and hammer the freewheel off by placing a chisel in what is left of the "lip" on the freewheel and striking it. This did not work at all, and just made me nervous in general.

    The shops in my area have given me two ideas, both of which they will not attempt.

    1 - have the freewheel welded together, and then attempt to remove it via a standard chainwhip

    2 - completely disassemble the the freewheel and attempt to dremel it off. In other words, disassemble the freewheel and then cut it down to just before the threads of the hub and then attempt to "pop" the freewheel in half.

    I figured this had to have happened to someone on this board at some time. I have a new ENO freewheel sitting here just waiting to be put on, but now I am not sure if I will ever get the Shimano f/w off the hub.

    Any advice GREATLY appreciated.

    Here is the problem with the "lip" on the freewheel if you can tell:

    I had that same problem before. When I first got into singlespeeding, I didn't realize there was a difference in some freewheels in that they needed two-prong tools to be removed. I had a really hard time finding one, so out came the Dremel.

    I used the bigger ones that are reinforced with fiberglass (#456). First I cut off the teeth section. I'd make one cut on one side, then go to the other side and cut there. That way the ring would split in half and removal would be easier. Then when I finally got to the inner ring - the one that threads onto the hub - I worked slower to make sure that I didn't touch the hub. I think I even made extra notches in the ring so that I could rest a big flat screwdriver to pry the ring open. A little finessed muscle and I took it off without damaging the hub.

    If you're careful, it's not that big a deal. Just remember to make two cuts on the ring so that it will split open.

    Sounds to me like welding the freewheel and using a chainwhip would be faster, easier and safer.

    Dismantle it in place by removing the cover then you can

    * attempt to grip what's left in a vice and unscrew it
    * if that doesn't work grind flats on to it and try again
    * if that doesn't work Dremel it off

    You don't need to cut through the toothed part - it comes off when you unscrew the cover and take the bearings out.

    a bit of penetrating lube/fluid doesn't go amiss either. We have Plus Gas in the UK - it's very good.

    also a bit of heat is handy too. But it can/will cook the bearings in your hub.

    Thanks for the advice,

    I got the freewheel off today. I could not get the inner lock ring off, so I dremeled the ring of teeth down to the lockring, then I notched the lockring with the dremel and pounded it off with a hammer and a flathead. After the lockring was off, I removed what was left of the ring of teeth, took out all the paws and ball bearings, and then put what was left in the vise and twisted it right off.

    It was pretty cool to see the inside of the freewheel, there is more junk in there than I thought there would be. I will be sure to use more anti-sieze with the ENO!

    Thanks Again Guys
