How to Remove a Crankset from Your Mountain Bike
To remove the crankset from a mountain bike, first, remove the pedals from the crank arms. Then, use a crank puller tool to remove the crank arms from the spindle. Make sure to apply the appropriate amount of force and follow the tool’s instructions carefully. Once the crank arms are removed, take off the bottom bracket by unscrewing it with a bottom bracket tool. Lastly, clean and inspect all components before reassembling or replacing them.
