Box News, The crank arm is pressured on and the only way you can get it out is with the crank puller. You definitely have to put a little strength into it but it will come loose.

Thanks very much.

What do I do if the crank remover tool isn’t work and the arm is stuck.

so it appears that you removed the crank arm by removing a nut and using device to remove it ...my problem is that the shaft that is left at 2:23 actually broke off from riding the bike and now the tip is embedded on the crank arm which i can remove , what is the name of the part i need to replace like i mention at 2:23 the part i need replaced is exposed on the bike ...is it the axle ? thank you in advance....i have an echelon bike if that helps

QUESTION: I am looking to replace the left crank on a bike and got one that is a different weight than the original. The original crank is pretty heavy in comparison to my new one. Will this weight make a difference when riding the bike? Thank you for your video and look forward to your response!
