How To Remove Bike Crank Without Puller?

 

What is a Bike Crank?

For you to fully understand this article, allow me first to describe to you what a bike crank is.  The bike crank is considered one of the vital parts of a bike.  This is the part that is responsible for converting your leg power into a circular motion, which allows the bike to move forward.  

The bike crank is also known as the crankset or chainset, and it is connected to the chain of the rear wheel of the bike.  It is located at the center of the bike and does most of the bike motions.  

To initiate the bike wheels to roll, you should start pedaling and keep the cranks turning.  When the crankset starts to move in a clockwise direction, the bike begins to pick up its momentum and begins rolling.  

Each type of bike comes in different crank lengths, just like saddles and handlebars.  And this only means one thing – that choosing an appropriate crank length is like finding a gem in a dessert.

Parts of a Bike Crank

Bike Crank Arm

Bike crank arm is simply referred to as the cranks.  They are installed on both sides with the axle serving as the connector, which is positioned within the bracket’s bottom.  

Cranks come in various types of materials, which includes carbon fiber, steel, and aluminum.  The most common type of cranks that is evident in standard and older types of bikes is made of steel.  

As for the aluminum cranks, they are commonly used on low to middle-ranged mountain bike and road bike cranksets.  And lastly, the carbon fiber cranks are generally installed on high-end cranksets of bikes that are meant for racing.   

Chainrings

Chainrings are basically the big sprockets or ring that you can find at the bottom of the bike frame.  They are responsible for facilitating the bike chain to mobilize the rear wheel, with the chain hugging, dragging, and spinning them.  

The material usually used in chainrings is aluminum that’s lightweight.  However, for middle-ranged cranksets, the middle and the small rings are made of cheaper steel.  

Chainrings are also created with teeth, which come in various sizes.  The number of teeth dictates the speed of a bike.  The more the teeth of a ring are, the more speed it has.  

All bikes have two rings. One is found side by side the rear wheel, while the other is just beneath the seat post.  The front ring is bigger than that at the back. 

When to Replace Your Bike Crank?

Every part of a bike is not spared from wear and tear and sooner or later, they will each have a time of reckoning.  Since this article is particularly centered on cranks, let me help you find out when it’s already time to replace your bike crank. 

The chainrings usually have a longer lifespan than the bike chain and the cassette.  Based on experience, I have only replaced my chainrings after the second time that I replaced my cassette and bike chain, wherein these two parts have to be changed all together.

Generally, a bike crankset is replaced just after a bike has covered more than 5,000 miles.  A bike chain checker is usually used to check the extent of wear and tear.  

However, the decision to replace your crankset depends on the bike mechanic.  Every mechanic typically has different criteria when it comes to bike crank replacement.  

Removing Bike Cranks Without Puller: Is it Possible?

So, if you are due to replace your bike crank, you can always let a bike mechanic do the job for you, or, if you are confident enough to know what you’ll be doing, you have all the freedom to do it on your own.  

One of the questions that I usually get is, “Is it possible to remove a bike crank without the help of a crank puller”?  Well, it is possible, but expect to be confronted with a very difficult task.  

Removing bike cranks without a special tool is not only exhausting, but it can also lead to damaged bicycle crank.   You’ll find several hacks or ideas over the internet that you can try, but they don’t always guarantee a successful outcome – this is actually very risky. 

Are crank pullers really needed in removing bike cranks? 

Again, it is alright to remove your bike cranks without a crank puller tool.  However, it is very challenging and there’s a big possibility that your bike will incur a number of damages.   

And yes, a crank puller tool is required in removing bike cranks.  If you’re aiming to remove your bike cranks effortlessly, then you should find it essential to buy a crank puller. Or, if you don’t want to shed a few dollars, then you can just borrow from a neighbor or a friend. 

Are crank pullers universal?  

When removing a bicycle crank, you have to make sure that the tip of the bike crank puller is compatible with the bottom bracket that is installed on your bicycle.  Keep in mind that the newer square taper crank models are universal, which means that any standard crank puller is suitable for the job.

Most threads of  bike cranks have a size of 22 x 1.  Long-standing cranksets make use of numerous sizes, but they are mostly found on vintage bicycles.

How to remove Crank with a Crank Puller steps

  1. Remove the crank bolt.  Twist the bolt following a counter-clockwise motion.  Doing so allows the bolt and crankset to loosen.  
  2. Remove the dust caps under the bolt.  Using an allen wrench, force the threads out or gently thread the bolt. This depends on the type of crank arms that you have on your bicycle.       
  3. By using a spanner tool or a bolt, start removing and loosening the washers.  
  4. Remove the crank bolt and the crank arm.  Make use of a CCP-22 or a CWP-7 if you have an M8 crank bolt.  But if what you have is an M12 or M14 bolts, use either a CCP-44 or also a CWP-7.  Use this in turning the threaded coupler of the crank puller.  Continue doing so until the bolt can already be buried out of it .  
  5. Insert the spindle driver into the slit and twist it following a counter-clockwise motion until the cranks become tight.  
  6. Once tightened, begin twisting the spindle driver in a clockwise motion, making sure that the bike crank arms are fully disengaged.  
  7. Now, unscrew the crank arms from the bike crank until it gets entirely removed.
