William trials Posted January 19, 2012 Report Share Posted January 19, 2012 i've recently broke my freewheel completly, when i took off the cranks my the sprocket on the freewheel fell off. so now when im gonna remove the old one with the right tools, it's stuck! but i have only tried with a 1,5 feet wrench to screv the crank arm off the freewheel. but i can't even get it to move a tiny bit. so i guess it's stuck, what do i do?

pogo Posted January 19, 2012 Report Share Posted January 19, 2012 Blow torch to expand it? Or just cut it off. Quote Link to comment Share on other sites More sharing options...

bella Posted January 22, 2012 Report Share Posted January 22, 2012 you cant heat up the cranks at all mate youll strip the treads with the next freewheel. i always use a impact air gun never heat up any alloy especially cast Quote Link to comment Share on other sites More sharing options...
