Remove the crank bolt or nut from the crank. When you do this, the crankset and bolt become free, allowing you to remove them with relative ease. This can be accomplished by twisting the bolt or nut in a counter-clockwise manner.
Insert an Allen key into the crank bolt and spin it counterclockwise until the crank is fully extended. To loosen the crank bolt, turn the Allen key handle in the opposite direction of the clock. Then use it to thoroughly loosen the crank bolt from the crankshaft nut. Go around to the other side of the bike and remove the second crank bolt if your crank has bolts on both sides of the bike.
How do you tighten the crank arm on a bike?
If these clamp bolts are not loose, you will need to release them before you can reattach the crank arm to the axle with a tensioning bolt. This tensioning bolt is most typically tightened with a specific tool that is not permanently attached to the bike. If you don’t have one on hand, you may make due by tapping the bolt around with a screwdriver or anything similar.
