PeanuckleJive Posted May 4, 2010 Report Share Posted May 4, 2010 yup, I know the technique for removing a sprocket from a full wheel, but thought I'd post this up for people's considerations. Been hooked up by alexrogers (sp?) with a cheap rear hub and sprocket as I need a sprocket for my new back wheel. He said the hub's knackered so if it's not at all salvagable I guess I can mod it to help me get the sprocket off. Anybody done this before, suggestions on how to do it? I'm torn between clamping the sprocket using a chain like usual and then gripping the hub body with a big pipe gripper and give it a swing OR if the hub really is knackered, Drill a hole straight through the body and out the other side and stick a bar through to use for leverage. Would the hub be able to take that force acting right in the middle of the body? I'm a caveman at heart, so I've probably missed a really logical method...

AlexxRogers Posted May 5, 2010 Report Share Posted May 5, 2010 (edited) Grind the hub shell to pieces! Its only the hub shell, so you may as well. Alex. EDIT: You should receive it today. Edited May 5, 2010 by AlexxRogers Quote Link to comment Share on other sites More sharing options...
Jamie_Trials Posted May 5, 2010 Report Share Posted May 5, 2010 If it is truely knackerd couldnt you grind off part of a flange at each side, surely that would work. Quote Link to comment Share on other sites More sharing options...

EDIT: You should receive it today. aye if it's totally screwed then that probably makes it easier Cheers man, Postman hasn't come yet so will let you know when it arrives Jamietrials, what you mean? Grind off part of the flange and get a big spanner on it or something? Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted May 5, 2010 Report Share Posted May 5, 2010 Wouldn't it be easier to just buy a new sprocket? They're not that expensive, and saves a lot of messing about! Quote Link to comment Share on other sites More sharing options...

Aye, but I'm skint until payday so £14 plus postage is actually quite a lot to me at the moment Alex gave me a hub and sprocket and I just had to pay postage, so if I can get it off the hub (which I'm sure is totally possible) it's a far cheaper option Quote Link to comment Share on other sites More sharing options...
ogre Posted May 5, 2010 Report Share Posted May 5, 2010 adjustable spanner + vice and some beefy chain... wrap the chain round the sprocket so that you miss a link and the chain "jumps" and 2 links stick out. get that in a vice, the links that stick out should stop the sprocket jumping free and spinning, then grind the flanges flat as suggested and get your adjustable on it...

Ben John-Hynes Posted May 5, 2010 Report Share Posted May 5, 2010 Could you fashion something to bolt onto the disk mount maybe? Get a piece of metal tube with some holes drilled in it for the disk tabs and bolt it on. Quote Link to comment Share on other sites More sharing options...

Get a piece of metal tube with some holes drilled in it for the disk tabs and bolt it on. I thought that, but alas it is non disk I'm gonna go at it in the morning, probably with varying degrees of intelligience I'm thinking a pipe wrench first, try to grip the hub body without any modification, if that doesn't work then grind two flats and get a big adjustable spanner on it Quote Link to comment Share on other sites More sharing options...
