Pete.M Posted October 12, 2012 Report Share Posted October 12, 2012 The sprocket on my CK hub appears to have dug into the freehub body and is totally stuck on. I've tried prising it and gentle knocking, but I can't knock it hard because I've no way of keeping the freehub locked in place! There's obviously not much space to get behind it, so can't hammer it from there either. Is my only option to get a 'gear puller'? Cheers.

Pete.M Posted October 12, 2012 Author Report Share Posted October 12, 2012 (edited) That could be a difficult job for me to do. It's not dug in that far by the looks of things. Seems weird that a CK sprocket with a wide base can get stuck on a CK hub... Edited October 12, 2012 by Pete.M Quote Link to comment Share on other sites More sharing options...
trials hoe Posted October 12, 2012 Report Share Posted October 12, 2012 clamp the freehub into the vice and use a chain whip? Quote Link to comment Share on other sites More sharing options...
Pete.M Posted October 12, 2012 Author Report Share Posted October 12, 2012 I'd be worried that clamping the freehub would damage it, but it might be an option. Quote Link to comment Share on other sites More sharing options...
trials hoe Posted October 12, 2012 Report Share Posted October 12, 2012 no soft jaws? or just use some pine or a soft wood or something to stop it marking the freehub body 1 Quote Link to comment Share on other sites More sharing options...
N.Wood Posted October 13, 2012 Report Share Posted October 13, 2012 Get another smaller sprocket to slide over the end of the hub and either clamp that or use a bit of chain in a vice to clamp it. Them hit the offending cog backwards. 1 Quote Link to comment Share on other sites More sharing options...

Pete.M Posted October 13, 2012 Author Report Share Posted October 13, 2012 Haha, that's the plan then. Hopefully I actually have another sprocket lying around.... Quote Link to comment Share on other sites More sharing options...

Them hit the offending cog backwards. Nearly, yes get a smaller sprocket and put that on but use two chain whips, one on the smaller sprocket so you can hold the freehub body steady and then the other on the stuck sprocket but the opposite way. Its a bit of a fag to get them both on at the same time but it works a treat if you dont want to damage any sprockets. Quote Link to comment Share on other sites More sharing options...
cultiv8ed_mike Posted October 15, 2012 Report Share Posted October 15, 2012 Assuming that you have an normal mtb style CK and have taken the cassette lockring off: Remove the driveshell (and take the axle out) then put it into a vice so that the shell is loose but the vice supports the ring. Stick some wood on top of the shell to protect the lockring threads then hammer the driveshell downwards. Quote Link to comment Share on other sites More sharing options...
