How do I take the pedal crank off my bike?
Use a 15mm wrench to loosen the left pedal from the bike. Then, hold the left pedal and rotate the crank arm to completely detach it from the bike. Both pedals should now be completely removed. If you’re standing on the right, or drive side, of the bike, rotate the crank arm clockwise.
What can I use instead of a crank puller?
You can also pry the threads out or remove them by slowly threading the bolt, depending on the crank arm type of your bicycle. Use a bolt or a spanner tool to remove and loosen the washers.
When should I replace my bike crank?
- The threads for the pedal get stripped/damaged to the point the pedal gets undone easily.
- The mating hole for the bottom bracket fretts and is no longer a good fit.
- Cracked crank arm – if the mating hole wears, and is retightened enough times, the crank arm slides too far onto the bottom bracket.
How do you remove a Shimano crank without a tool?
Simply place the crank extractor inside the crank bolt hole, rotating it clockwise until tight, before turning it counterclockwise so that the crank comes off. Remove the crank from the other side of the bike in the same manner and, voila, you’ll have officially removed your crankset just like that.
