Completly taking apart my mongoose front and rear suspension mountain bike I came accross no real problems except getting the chain wheel crank off on my two-peiece crank set.
I got the opposing side's lock-nut and everything else out fine but upon screwing the crank-pulling tool into the inside of the crank and then turning the bolt inwards resulting in griping onto the thread and de-attatching it from the axle it gripped onto the thread -and pulled it out.
Lots of metal shavings later I can't even screw the tool into the crank now, there's that little thread.
Now without having to buy specialised tools or whatever else what's the best way to get the crank off? Any help greatly appreciated.
