Jason222 Posted July 23, 2007 Report Share Posted July 23, 2007 Alright guys, I put a single speed cog on my chris king universal hub. It's a 16 tooth cog, and I want to switch it for a 15 tooth. But my problem is that the cog is dug in to the aluminum freehub body really badly and I can't seem to get it out. Do you guys have any ideas on how to get it off?

Janson Posted July 23, 2007 Report Share Posted July 23, 2007 First try putting another cog on the frehub. Then wrap chain whips around both cogs and try to twist them off. If that doesn't work, try with more force.If that doesn't work either, you might have to get the file out. It's what I did with my DT Hügi hub a few years ago, I filed the freehub body next to the cog. I filed the little ridges off that had formed due to the cog digging in. A bit of violence and filing got the cog off every time. It's not very good for the freehub, but beggars can't be choosers... Quote Link to comment Share on other sites More sharing options...
willy wonka Posted July 23, 2007 Report Share Posted July 23, 2007 I once spent about an hour trying to get one off before.I just couldn't get it off.But I accidently dropped and the cog fell off, so try dropping your hub.... Quote Link to comment Share on other sites More sharing options...
Tomm Posted July 23, 2007 Report Share Posted July 23, 2007 I use the adjustable hammer. Once you loosen it a bit, it sometimes comes off. That might depend on how much it's dug in though. Quote Link to comment Share on other sites More sharing options...
robb_o Posted July 23, 2007 Report Share Posted July 23, 2007 I'm still running a rear DT Hugi hub! and I have the same problem (but with an 8 speed cassette).i use some bit molegrips on the freehub body and twist the cassette off with a chain whip tool.

Si-man Posted July 23, 2007 Report Share Posted July 23, 2007 Rubber mallet, twat it in the non freewheeling direction.Had to do it to a cassette last night after it burrowed its way into my Pro II freehub. Quote Link to comment Share on other sites More sharing options...
Jason222 Posted July 23, 2007 Author Report Share Posted July 23, 2007 Now I'm having problems with my crown race, I removed it from my old fork quite easily, but I'm having trouble getting it all the way down on my new echo urban fork. There seems to be about 6-8 mm of extra room below the crown race when I put it on. Is this normal? Is there a way to fix it easily? Quote Link to comment Share on other sites More sharing options...

Fixed Pants™ Posted July 23, 2007 Report Share Posted July 23, 2007 For the crown race; a good bodge is to use your stem as a slide hammer, just put the stem on the steerer tube, and twat it a good un a couple of times until it's there, never done me any harm, also gets it on nice and evenly.

Greetings Posted July 23, 2007 Report Share Posted July 23, 2007 I used a screwdriver and a hammer, pushed the screwdriver through the spokes, rested it on the cog and hammered it out. If it's in too deep, you might want to use a file as Janson suggested. Quote Link to comment Share on other sites More sharing options...
Jason222 Posted July 23, 2007 Author Report Share Posted July 23, 2007 Thanks, that stem+crown race thing worked like a charm. Havent tried getting the cog off yet, I've been rather busy, but thanks for all the suggestions!!! Thanks everyone! Quote Link to comment Share on other sites More sharing options...
Yurich Posted July 23, 2007 Report Share Posted July 23, 2007 Thanks, that stem+crown race thing worked like a charm. Havent tried getting the cog off yet, I've been rather busy, but thanks for all the suggestions!!! Thanks everyone!What you need to do is put another cog on there, take two chain whips (borrow one at a shop), and un-twist it until it's centered in the spline. Then, force it Quote Link to comment Share on other sites More sharing options...
Jason222 Posted July 24, 2007 Author Report Share Posted July 24, 2007 I might try that at the bike shop tomorrow. I have to go there to get some bearings for my front hub, buy new bb7 brake pads, a rear tube, and a rear derailleur cable. lol Quote Link to comment Share on other sites More sharing options...
br3n Posted July 24, 2007 Report Share Posted July 24, 2007 2 chain whips and a vice. Quote Link to comment Share on other sites More sharing options...
Onza Kieron Posted July 24, 2007 Report Share Posted July 24, 2007 Just a word of advice for fitting the race, I use an old pig unsealed bottom cup, flip it upside down and slide it down the forks, this provides a large area to hit with hammer and doesn't damage anything, including the stem..
