Shimano 600 crank WONT COME OFF!!!!!!
This crank, man. I know it's self extracting. It says "One Key Release" on the ring and on that ring there are also two really small wholes. I don't know if I'm supposed to stick something in those holes. The bolt is 6mm wide and has a hex shape. So I use my 6mm allen wrench, turn it counter clockwise, and get it lose. I think I'm done but after half a turn it gets tight and I'm like wtf? But now I know self extracting cranks are supposed to that and I'm supposed to keep turning, but it's so freakin' tight. I put on gloves to give it more torque but that just screwed up the allen wrench (i.e. it ROUNDED) so know it doesn't even fit. I tried the other side of the allen wrench but the same thing happened.
Do I need a special tool to do this? Am I supposed to do something with those holes? Does it matter that I'm doing this on the driver side first? It just gets so ridiculously tight and all the shops tell me to just keep turning but all that does is turn the allen wrench into a cylinder.
What am I supposed to do? Oh, and here are pics.
