The Stig Posted June 15, 2008 Report Share Posted June 15, 2008 Get the "proper tool" and put it in a vice clamping the sprocket and with a big arse pole turn it with ease Quote Link to comment Share on other sites More sharing options...

txt2007 Posted June 15, 2008 Report Share Posted June 15, 2008 yeah i ahd the same problem i just made my own tool worked a treat but i think it would be worth investing in the proper tool if you dont want to spend a load of time and effort making one yourself cuz how much are they about a fiver, by the time id made one i might as well've bought it...

Ladd Posted June 15, 2008 Report Share Posted June 15, 2008 do you have a vice bolted to a bench ? if so do this.. Get your old cog put it in the vice clamp it in very very tight so its crushing the teeth then put a pole on your crank arm about 3ft scafold pole then turn it helps to put abit off WD40 on aswell .

Tango Posted June 15, 2008 Report Share Posted June 15, 2008 Get a blow torch and heat the bugger up then it'll come off easy as pie! Quote Link to comment Share on other sites More sharing options...
Pagie Posted June 15, 2008 Report Share Posted June 15, 2008 Funnily enough ive had this issue before... This is how i solved it... Tools Needed: Vice Hammer Blow Torch Heat your chainring up, smash two opposing sides off the chainring... Clamp in the vice, Apply abit more heat to expand the threads on the chainring and unwind your crank arm if it wont go by hand give it abit of pasty with the hammer!

monty221pr Posted June 15, 2008 Report Share Posted June 15, 2008 wrap the cog in an old bit of chain and itll clamp better in the vice Just need sum serious girth to muscle it off Sam. Quote Link to comment Share on other sites More sharing options...
The Duck Posted June 15, 2008 Report Share Posted June 15, 2008 Tried cutting two flat edges out of it with an angle grinder or a hacksaw, then whacking it in the vice? Can't believe you haven't got it off with a blowtorch and a vice... Quote Link to comment Share on other sites More sharing options...
Revolver Posted June 15, 2008 Report Share Posted June 15, 2008 Can't believe you haven't got it off with a blowtorch and a vice... I don't think he's tried that yet. to be honest if it wont come off by any conventional methods (cloth, vice and bar), you're not going to be able to save the chainring. What you could do is grind away at the chainring very close to the threads in two spots, making it very thin but not damaging the threads of the crank. Then if you hit it hard enough it will snap apart and come off. Quote Link to comment Share on other sites More sharing options...
Ashley-Wood Posted June 16, 2008 Author Report Share Posted June 16, 2008 Whayy got it off ;] but to flat edges put it in vice with a blow torch constantly on it and got my dad to turn it as hard as he could and still didnt come off with ease but came off !! cheers lads Quote Link to comment Share on other sites More sharing options...
