Tools and Materials Needed

To remove a bike crank without a crank puller, you will need the following tools and materials:

• A 15mm wrench
• A 14mm wrench
• A hammer
• A punch
• A block of wood
• Grease

Step-by-Step Instructions

1. Remove the pedals. To do this, loosen the pedals with a 15mm wrench. Once the pedals are loose, you can remove them by turning them counterclockwise.
2. Locate the crank bolt. The crank bolt is located on the non-drive side of the bike. It is a large bolt that holds the crank arm to the bottom bracket.
3. Loosen the crank bolt. Use a 14mm wrench to loosen the crank bolt. Be careful not to over-tighten the wrench, as you could damage the bolt.
4. Insert the punch into the crank arm. Insert the punch into the hole in the crank arm, directly opposite the crank bolt.
5. Strike the punch with the hammer. Strike the punch with the hammer several times. This will loosen the crank arm from the bottom bracket.
6. Remove the crank arm. Once the crank arm is loose, you can remove it by pulling it straight up.
7. Grease the threads of the new crank arm. Apply a small amount of grease to the threads of the new crank arm. This will help to prevent the crank arm from seizing to the bottom bracket.
8. Install the new crank arm. Align the new crank arm with the bottom bracket and install it by turning it clockwise.
9. Tighten the crank bolt. Use a 14mm wrench to tighten the crank bolt. Be careful not to over-tighten the bolt, as you could damage the bolt or the crank arm.
10. Reinstall the pedals. Reinstall the pedals by turning them clockwise.

By following these steps, you can remove a bike crank without a crank puller. This is a relatively simple process, but it is important to be careful not to damage the bike. If you are not comfortable doing this yourself, you can take your bike to a bike shop and have them remove the crank for you.

How do I remove a bike crank without a puller?

There are a few ways to remove a bike crank without a puller. Here are two methods:

• Method 1: Using a hammer and screwdriver

1. Flip the bike upside down so that the cranks are facing the sky.
2. Locate the crank bolt on the non-driveside crank.
3. Insert the tip of a screwdriver into the slot in the crank bolt.
4. Using a hammer, tap the screwdriver handle to loosen the crank bolt.
5. Once the crank bolt is loose, you can use your fingers to unscrew it the rest of the way.

• Method 2: Using a wrench and a metal rod

1. Flip the bike upside down so that the cranks are facing the sky.
2. Locate the crank bolt on the non-driveside crank.
3. Insert the end of a wrench into the hex nut on the crank bolt.
4. Thread a metal rod through the hole in the crank arm and into the wrench.
5. Using the wrench and metal rod, turn the crank bolt counterclockwise until it is loose.
6. Once the crank bolt is loose, you can use your fingers to unscrew it the rest of the way.

What if the crank bolt is stuck?

If the crank bolt is stuck, you can try using a penetrating oil to loosen it. Penetrating oil is a type of lubricant that can help to dissolve rust and other deposits that may be preventing the bolt from turning. To use penetrating oil, spray it onto the threads of the crank bolt and let it sit for several minutes. Once the oil has had time to work, try to loosen the bolt again using one of the methods above.

If the crank bolt is still stuck, you may need to use a more aggressive method to remove it. One option is to use a heat gun or torch to heat the crank arm. This will help to expand the metal and make it easier to turn the bolt. Another option is to use a penetrating oil and a breaker bar. A breaker bar is a long, heavy bar that is used to provide more leverage when turning a bolt.
