My unicycle cotterless crank is loose
http://i304.photobucket.com/albums/n...P1070367-1.jpg
--- There's a picture of my left crank which adjusts side to side when it's not supposed to. Whenever I try to tighten the black wheel thing inside of the left crank it still moves slightly side to side. I also noticed that when I compared the right and left crank there was a hole in the middle of the left crank (the one that needs fixing) and no hole on the right crank. Is it supposed to be like that and if not what piece am I missing? |

Is it supposed to be like that and if not what piece am I missing? I recommend taking it to a bicycle shop. They deal with cotter-less cranks every day. That is the same on both wheeled vehicles. It should be relatively cheap fix. If not they will be able to advise you on your realistic options. If I were working on it, I would try driving the crank arm on to the shaft with a hammer. Place a wood block over the crank arm with the other arm lying on a board (axle vertical - not close to vertical, vertical), blast it with a hammer, tighten the nut, repeat.
