1. If your crank arm is oval and keeps falling off. When replacing the bolt, keep the crank arm connected for a while, but eventually it will fall off. If this happens, you will need a new crank arm. When the square cone becomes oval due to wear, it will withdraw from the bolt.
2. If your crank arm bolt is stripped, this is usually due to the bottom bracket shaft thread, not the crank, in which case you will need a new bottom bracket shaft.
