The Ultimate Guide to Bike Crankshaft Removal: A Step-by-Step Approach

When it comes to bicycle maintenance, one of the essential tasks is bike crankshaft removal. This process involves detaching the crankset from the bottom bracket of your bike, which allows you to clean, repair, or replace various components. In this guide, we’ll walk you through the process of bike crankshaft removal in a step-by-step manner, ensuring a smooth and hassle-free experience.

Step 1: Gather the Necessary Tools

Before you begin the bike crankshaft removal process, make sure you have the following tools on hand:

  • Crank puller
  • Allen wrenches (typically 5mm or 8mm)
  • Adjustable wrench

Step 2: Remove the Crank Bolt or Nut

Start by removing the crank bolt or nut that secures the crank arm to the bottom bracket spindle. To do this, use the appropriate size Allen wrench or adjustable wrench.

Step 3: Insert the Crank Puller

Next, thread the crank puller into the crank arm hole where the bolt or nut was removed. Ensure the puller is fully engaged and securely in place to prevent damage to the crank arm threads.



Step 4: Detach the Crank Arm

Now, use the adjustable wrench to turn the crank puller’s handle clockwise. This action will force the crank arm away from the bottom bracket spindle. Once the crank arm is detached, unthread the crank puller.

Step 5: Repeat for the Other Side

Perform the same process on the opposite crank arm to complete the bike crankshaft removal.
