Mountain biking is a beloved pastime for many outdoor enthusiasts, providing an adrenaline rush and a chance to explore rugged terrain. However, as with any activity, wear and tear can lead to the need for repairs and maintenance. One common issue is having to remove the pedal arms, which can become stuck or stripped over time.
Removing pedal arms may seem like a daunting task, but with the right tools and knowledge, it can be a relatively simple process. In this step-by-step guide, we will walk you through the necessary steps to remove the pedal arms from your mountain bike, allowing for smoother rides and more enjoyable trips on the trails.
Identifying the Type of Pedal Arm
Before you begin to remove the pedal arms from your mountain bike, you need to identify the type of pedal arm that is on your bike. There are two types of pedal arms, square taper, and splined. Identifying which of these two types your bike has is important because the removal process for each type of pedal arm is different.
The square taper pedal arm is one of the most common types of pedal arms found on mountain bikes. It has a square end that fits into the crank arm. On the other hand, the splined pedal arm is a newer type of pedal arm that uses a series of interlocking teeth on both the crank arm and the pedal arm to attach them together. It is generally considered to be a stronger and more secure attachment than the square taper. Knowing the type of pedal arm on your bike will help you make informed decisions on how to remove it without damaging your bike.

Required Tools for Pedal Arm Removal
Removing the pedal arms from your mountain bike can be a daunting task, especially if you’re new to bike repairs. However, with the right tools and a little patience, anyone can remove the pedals from their bike. The first step is to gather all the necessary tools required for pedal arm removal.
The required tools for pedal arm removal include a pedal wrench or a 6mm Allen key, a socket wrench, and a chain whip tool. A pedal wrench or 6mm Allen key is necessary to remove the pedals from the bike. A socket wrench is essential for removing the cranks from the bike while the chain whip tool is necessary for holding the cassette in place and preventing it from rotating while removing the crank. By having these tools ready, you can make the process much easier and faster.
Removing the Pedal Arm from the Crank
Once you have successfully removed the pedal from the crank, the next step is to remove the pedal arm from the crank. This can be a bit more challenging as the pedal arm is usually tightly secured to the crank and requires a little more effort to remove.
To remove the pedal arm from the crank, you will need to use a crank puller tool. The tool attaches to the pedal arm and uses a threaded spindle to push against the bottom bracket spindle. This pushes the pedal arm off the crank.
Before using the crank puller, you will need to first remove any washers or spacers between the pedal arm and crank. Once these are removed, attach the crank puller to the pedal arm and turn the tool’s handle clockwise until the pedal arm pops off the crank. This may require some force, so make sure to use your full strength. Once the pedal arm is removed, you can then proceed to replace or maintain the component.

Tips for Dealing with Stubborn Pedal Arms
When it comes to removing pedal arms from a mountain bike, you may encounter some stubborn ones. It can be due to rust, debris, or improper installation. Here are some tips to help you deal with stubborn pedal arms.
Firstly, apply some lubricant, such as penetrating oil, to the area where the pedal arm is attached. This will help loosen the pedal arm from the crank, making it easier to remove. If the pedal arm is still stubborn, you can put a wooden block in between the pedal arm and the bike frame and gently tap it with a mallet. This will help loosen the pedal arm without damaging the bike. Alternatively, you can use a pedal wrench or a hex wrench to turn the pedal arm in the opposite direction of your bike’s rotation. Remember, patience is key when dealing with stubborn pedal arms.
Cleaning and Lubricating the Crank and Pedal Threads
After separating the pedal arms from your mountain bike, it’s crucial to perform a deep cleaning of the crank and pedal threads to ensure smooth operation. Dirt, grime, and rust can accumulate on the threads, causing damage and making it difficult to remove or attach the pedal arms.
Start by using a stiff brush to remove any debris or dirt from the threads. Then, apply a penetrating oil or rust remover to dissolve any rust or corrosion on the threads. Use a cloth to wipe away excess oil and any remaining dirt. Finally, apply a lubricant designed for bike components to the threads to ensure easy attachment and removal of the pedal arms in the future. Proper cleaning and maintenance of your mountain bike’s crank and pedal threads will prolong the life of the bike and improve its overall performance.
Reassembling the Pedal Arms
After successfully removing the pedal arms from your mountain bike, it is time to reassemble them back. First, make sure that the threads of the crank arms and pedals are clean and free of debris. Use a clean rag or a brush to clean them if needed. Apply a small amount of grease onto the threads of the pedals and crank arms to reduce friction and make the rotation smoother.
Line up the pedal arms with their corresponding crank arm and screw them in clockwise until they are tight. Use a pedal wrench or an adjustable wrench to tighten the pedals securely onto the crank arms, but be careful not to over-tighten them, as this can damage the threads. Finally, give the pedals a spin to make sure they are rotating smoothly and securely. With these simple steps, reassembling the pedal arms will be a breeze, allowing you to get back on your mountain bike in no time.

Testing the Pedal Arm Functionality
After successfully removing the pedal arms from your mountain bike, it is important to test their functionality before reassembling the bike. This step ensures the pedals are not only properly installed but also in good condition.
To test the pedal arm functionality, first, inspect the threads on the pedal arm for any damages. If there are any damages, replace them immediately. Next, thread the pedals back onto the crank arms, ensuring they are tight and snug. Finally, spin the pedals to check if they rotate smoothly without wobbling or making any unusual noises. If there are any issues, investigate further or seek professional help before riding the bike again. Overall, testing the pedal arm functionality is an essential step to make sure your mountain bike is safe to ride and functions correctly.
The Conclusion
In conclusion, removing pedal arms from a mountain bike may seem daunting, but it can be easily done with the right tools and techniques. By following the steps outlined above, you can successfully remove the arms and replace them with ease.
It is important to remember to always take your time and be patient when working on your bike. Rushing or using improper tools can lead to damage or injury. By properly maintaining your bike and regularly checking and replacing components as needed, you can ensure a safe and enjoyable ride every time.
