HippY Posted October 30, 2014 Report Share Posted October 30, 2014 Hey guys I am just wondering if there is any way to Remove a screw on sprocket from a hub with a chain whip and no vice Remove the crown race from the fork (I am not sure if i want to do it, you will see) Installing the freewheel on a crank The reason why I ask because if I will not be able to make them I must take them to my local bike shop, and to be honest, last time he tried to take off my freewheel with a hammer and a screwdriver.... Removing the crownrace should be fine with hum I guess, as it is nothing special, he already installed freewheel for me so that is good, but I am not sure about the screw on sprocket.

A bike shop w/o a vice? Quote Link to comment Share on other sites More sharing options...

niconj Posted October 30, 2014 Report Share Posted October 30, 2014 they *should* have but I do not I you don't need the sprocket anymore, you could Dremel it off. I don't think you'll get enough force to screw it off with a chain whip. About the crown race. Just take a thin knife and a hammer. Put the blade in between the fork and the crown race and go all around the fork slightly hammering on the back of the blade. I do this with carbon forks to not damage the seat of the crown race.

It started nicely then stopped... I will go to the local bike shop do I need a special tool to tighten the sporcket and freewheel or it will tighten itself? (after hand and chainwhip tight Quote Link to comment Share on other sites More sharing options...
N.Wood Posted October 30, 2014 Report Share Posted October 30, 2014 It'll tighten its self. Quote Link to comment Share on other sites More sharing options...
niconj Posted October 30, 2014 Report Share Posted October 30, 2014 It started nicely then stopped... I will go to the local bike shop Take a bigger knife and move it in there. Then you can use the knife as a lever going around the crown race. Just don't use the tip of the knife but the blade. You can lever it up (is this how it's called?) a bit and then go a bit further round. Quote Link to comment Share on other sites More sharing options...

dezmtber Posted October 31, 2014 Report Share Posted October 31, 2014 I have an updated chainwhip at work for screw on sprockets. It uses some of that bmx chain as big as moped chain and a very very long handle extended to just over 1 meter long, and a spring loaded bit on the end of the chain to hold it onto the cog so there's no slipage. Works every time. Quote Link to comment Share on other sites More sharing options...
