What You’ll Need
- Crank puller tool

- Thread the crank puller tool securely into the crank arm.
- Tighten the crank puller to slowly push the crank off the spindle using steady pressure.
- Once it pops off, remove the crank puller.
Step 2: Install the New Crank
- Apply a small amount of grease to the outside of the spindle. Avoid getting it inside.
- Align the new crank so it’s opposite the other arm and slide it onto the spindle.
- Insert and tighten the center bolt. Use a torque wrench for the most secure fit.
- Reposition the chain on the crank once installation is complete.
