Daniel C Posted April 23, 2008 Report Share Posted April 23, 2008 i was just wondering on my cranks my freewheel looks cross threaded and my freewheel is fooked so i need to get it off but i dont want to strip the threads off my crank so i was wondering what do you think the threads would come off first the freewheel or the cranks?and is there any way of getting it off without damaging anything?my cranks are echo forged and my freewheel is acs Quote Link to comment Share on other sites More sharing options...
forteh Posted April 23, 2008 Report Share Posted April 23, 2008 The crank threads will fail first, although if its crossthreaded the threads on the crank are already f**ked You could cut the freewheel off the cranks if its not budging. Take the lock ring and gubbins out of it, hold the crank arm in a vice, and grind a groove across the width of the freewheel inner - you dont want to go through the steel inner as that will really knacker the threads. When theres 2-3mm of steel left get a cold chisel and tap into the groove, with any luck the inner should crack and come free of the threads alittle I seem to remember something about deng cranks not being machined true and the freewheel wobbling about as the cranks turned, could it be that?

Bionic Balls Posted April 23, 2008 Report Share Posted April 23, 2008 have you been using it like it is? if you have...i doubt that the threads really are "frenched"..and..if it screwed on..it should screw off without doing any more damage than it already has..does the entire freewheel sit on the crank, or is there a large "overhang"?adam Quote Link to comment Share on other sites More sharing options...

Bionic Balls Posted April 23, 2008 Report Share Posted April 23, 2008 that's not usually anything to worry about then...so does mine if you need to take it off...just do it- you don't really have any choice! Quote Link to comment Share on other sites More sharing options...
