And suddenly you decide to take your bike for a ride, and every time you pedal an annoying sound follows. If you get what I am saying, then it’s high time, get your hands dirty and get through with it.
Some other reasons that can force you to change your bike cranks could be as small as monthly maintenance, service the bottom bracket bearings of your bike to changing the sprockets itself.
Whatever the reason might be, we will help you get through it especially if you’re planning to save some bucks behind the puller.

Easy Steps To Remove Bike Crank Without Puller
Before you start with the process, it’s essential to identify what type of crankset it is.
Just in case it’s a self-extracting crankset, scroll down to the part – How to remove self-extracting crankset.
The process of removing the crank from your bike is a cakewalk if you have minimal mechanical skills. It does not require you to be a know-it-all.
With a minimal idea of how things work, it might take up to a few hours to get the job done.
However, it is advised to use this method only if it is an emergency where you cannot reach an expert or a professional to help you. It is recommended to reach out to them for such work as doing it yourself might take a lot of time if you do not own any experience. Now, without any further ado, let’s get started with the process.
The tools and materials required in this process are already mentioned above.
The steps to disconnect your bike’s crank without a puller are as follows:
1. Protect your hands
This should be your foremost priority when working with any mechanical parts. Use rubber gloves if possible, as they can provide utmost protection to your hands.
Leaving your hands bare can be prone to injuries, not just by the crank but other parts too. The professionals advise it. Ergo, before starting with any kind of work, make sure your hands are covered.
2. Start with removing the crank bolts.
For this process, you’ll need a universal wrench. Simply turn all the nuts/bolts counterclockwise to loosen them. Once you make sure the nuts are loose, remove the crankset and stick out to the crank of your bike.
Note: Do not hurry during any of these processes. As they say, “Haste makes waste.”
Once done now remove the washers carefully. If you’re a recruit and have no idea what a washer is, a washer is a straight metal disc that helps the nut and the bolt remain tight.
Carefully remove all the washers using a spanner tool and keep them aside.
They’re usually located under the nuts.
3. Identify And Remove Crank with Coupler
Nuts and Bolts are available in various sizes, and it’s essential to identify the size of the nut and bolt used in your bike and choose proper tools accordingly.
For smaller cranks like an M8 crank bolt, use a CCP-22 or a CPW-7 to get the job done.
For larger cranks like M12 or M14 Crank bolt, use a CCP-44 to get the work done.
Now to take out the Coupler with threading on both ends; it is advised to use a hex tool and a spanner or a screwdriver. Once you have got the right tool, with not much pressure, turn the coupler until you can quickly move the hex around. Try not to remove it wholly as it may damage the surface.
4. Disengage the arms of the bike’s crank
Mind you; this process will test your arm strength to certain limits. Take out the spindle using the spindle driver.
Once you’re finished with the previous task, it’s time to tighten the spindle with the arm of your bike. The process might look more complicated than it is. You simply slide the driver right into the spot and rotate it in the anti-clockwise direction until it’s tight.
To disengage them, you need to rotate the spindle in a clockwise direction. Do not apply too much pressure as you might end up hurting your hands in this process.
5. Remove the Crank arm puller tool.
Once you’ve disengaged the crank arm from the body, all that is left is to remove the crank arm of your bike. Again, avoid using a lot of force; you might end up injuring yourself.
Next Do it on the other end as well.
By now, you’ve successfully removed one side of the crank. Use the same method on the other side as well. Make sure to follow each step here with caution. Failing to do so might end you up in a bad situation.
In case you already are in a situation like this, do scroll down and check ‘Time to get help.’
How to remove a Self Extracting Bike Crank
A self-extracting crank in a bike moves even without the help of a puller; that’s the easiest way to understand whether your bike has a self-extracting crank or not.
In a self-extracting crank system, the retaining ring itself acts as a crank bolt and functions as a crank puller once the crank bolt is loosened.
That makes self-extracting cranks preferable as it takes only one tool to remove the crank- Alley Keys. But is that it? No, for sure, that not all you would need.
There are always specific miscellaneous tools and equipment that are required in such processes- A pin spanner or a hex wrench for the retaining cap and bolt, a mallet to push your crankset to the other side of your bike, and a wipe/rag to keep the area and your hands clean.
Note: Not every crankset is the same. Sometimes it is not necessary to remove the retaining ring. Ergo, it is advised to identify the type of crankset you’re working with.
- Remove the retaining cap using a pin spanner.
- Then remove the arm using a Hex wrench. Turn counter-clockwise until the arm falls off away from the spindle.
- Once that is done, you will be left with the other side of the arm. Pull it out slowly or use a mallet to do so.
- Here you go, you’ve successfully removed your elf extracting bike crank.
These four steps will help you extract your bike crank without any inconvenience.
Time to get help
Understand when you’ve gone too far with the process and, in such times, dive for help.
When you’re unable to do anything or get stuck in a circle, neither should you panic, nor should you continue applying force in any case.
Doing so might lead to a bigger problem might even lead to permanent damage to your bike. If we had to put this in a sentence- “Better safe than sorry.”
In such desperate times, seek help from professionals. Look for a nearby Bike repair or a Bike mechanic to help you with this problem.
The problem can range from merely fitting your threaded bolt in your crank to getting your crank stuck in your bike. If you find yourself under a similar circumstance like this, then seek experts’ advice, as it’s no use crying over spilt milk.
