Step-by-Step Guide: How to Remove Pedal Crank from Your Mountain Bike
To remove a pedal crank from a mountain bike, first identify the type of crank and the size of the crank bolts needed to remove it. Use a crank puller tool to loosen the crank arm from the bottom bracket spindle and remove the bolt. Gently tap the crank arm with a rubber mallet until it comes loose from the spindle. Slide the crank arm off the spindle and repeat the process on the other side to remove the entire crankset.
