Removing a bicycle crank is an essential skill for any cyclist who wants to maintain their bike. The process of removing the crank can be daunting, especially if you don't have a crank puller. However, with some simple tools and the right technique, you can remove your bicycle crank without a crank puller. In this article, we'll take a step-by-step approach to guide you through the process of removing your bike's crank without a puller.

Firstly, it is important to understand how a crank is attached to a bike. The crank is attached to the bottom bracket, which is the part of the bike that holds the bearings of the pedals. To remove the crank, you need to detach it from the bottom bracket. There are two main types of cranks - the square taper cranks and the splined cranks. The method for removing each of these types differs, but we will cover both in this article.

If you have a square taper crank, the first step is to remove the dust cap that covers the center of the crank. This can be done using a flathead screwdriver or a small pry bar. Once the dust cap is removed, you will see a bolt in the center of the crank. Use a wrench to loosen this bolt by turning it counterclockwise. It may take some force to loosen the bolt, so make sure you have a good grip on the wrench.

After loosening the bolt, you will need to remove the crank arm from the bottom bracket. To do this, you can use a rubber mallet or a block of wood to gently tap the crank arm until it comes loose. If the crank arm is still stuck, you can use a pry bar or a large flathead screwdriver to carefully pry it off. Be careful not to damage the crank arm or the bottom bracket.

For splined cranks, the process is slightly different. The first step is to remove the bolt that holds the crank arm in place. This bolt is typically located on the non-drive side of the bike. Use a wrench to loosen the bolt by turning it counterclockwise. Once the bolt is removed, you should be able to pull the crank arm off by hand.

If the crank arm is still stuck, you can use a rubber mallet or a block of wood to gently tap it until it comes loose. If it still won't budge, you can use a pry bar or a large flathead screwdriver to carefully pry it off. Again, be careful not to damage the crank arm or the bottom bracket.

Once you have removed the crank arm, you will need to remove the chainring from the crank. To do this, you can use a chainring tool or a large screwdriver to carefully pry the chainring off. Be sure to keep track of any washers or spacers that may be between the chainring and the crank arm.

With the chainring removed, you can now remove the other crank arm using the same method as before. Once both crank arms are removed, you can then remove the bottom bracket using a bottom bracket tool. This tool is specifically designed to fit the grooves on the bottom bracket and allow you to remove it.

In conclusion, removing a bicycle crank without a crank puller is entirely possible with the right technique and tools. Whether you have a square taper or splined crank, the process is relatively straightforward. Just be sure to take your time and be careful not to damage any parts of your bike. With a little practice, you'll be able to remove your bike's crank like a pro.


Introduction

A bicycle crank is a very crucial component of your bike as it transfers power from your legs to the rear wheel. It is responsible for rotating the chainring and propelling you forward. However, there may come a time when you need to remove the crank for maintenance or replacement. Many people believe that a crank puller is necessary to remove a crank, but this is not entirely true. In this article, we will discuss how to remove a bicycle crank without a crank puller.

Gather the Necessary Tools

Before you begin removing the crank, you will need to gather the necessary tools. You will need a wrench set, a rubber mallet, and a flathead screwdriver. It is important to make sure that the wrench set you have includes a 14mm socket wrench as it is essential in the removal process.

Remove the Crank Bolts

The first step in removing the crank without a puller is to remove the crank bolts. These bolts hold the crank arms onto the bottom bracket spindle. Use the 14mm socket wrench to loosen the bolts. Ensure you turn them in an anti-clockwise direction.

Removing the Dust Cap

Once you have removed the bolts, the next step is to remove the dust cap from the crank. The dust cap is located on the non-drive side of the crank. Use the flathead screwdriver to remove the cap by gently prying it off.

Removing the Retaining Nut

Underneath the dust cap, you will find a retaining nut. Use the 14mm socket wrench to remove the nut by turning it in an anti-clockwise direction. Be careful not to lose any washers or spacers that may be located under the nut.

Removing the Crank Arm

Once you have removed the retaining nut, it is time to remove the crank arm. Gently tap the end of the crank arm with a rubber mallet to loosen it from the spindle. Once it is loose, you can use your hands to pull it off the spindle.

Removing the other Crank Arm

Repeat the same process for the other crank arm by removing the bolts, dust cap, retaining nut, and then using the rubber mallet to gently tap it off the spindle.

Removing the Bottom Bracket

If you need to remove the bottom bracket, you can do so by using a wrench set that includes a bottom bracket tool. Insert the tool into the bottom bracket and turn it in an anti-clockwise direction to loosen it. Once it is loose, use your hands to remove it from the frame.

Cleaning and Maintenance

Now that you have removed the crank and bottom bracket, you can clean and perform any necessary maintenance. Use a degreaser to clean the crank arms and bottom bracket spindle. Check for any signs of wear or damage and replace any parts as needed.

Reinstallation

After performing any necessary maintenance, it is time to reinstall the crank arms and bottom bracket. Follow the reverse order of the removal process to reinstall the components.

Conclusion

Removing a bicycle crank without a puller may seem like a daunting task, but it is possible with the right tools and techniques. By following the steps outlined in this article, you can remove and reinstall your crank and bottom bracket for maintenance or replacement. Remember always to be careful, take your time, and ensure you follow the correct procedures to avoid causing any damage to your bike.
