This blog post will teach you how to remove a bike crank without a puller. We’ll also explain the indicators that your bike cranks need to be replaced. Stay tuned!
What Are the Signs That Your Bike Crank Needs to Be Replaced?
Bike cranks can last for years without showing any signs of wear or needing to be replaced. However, eventually, they will reach the end of their lifespan and need to be swapped out for a new one. Here are some signs that your bike crank may need to be replaced:
Making Creaking or Grinding Noises
If you hear any unusual noises coming from your bike crank, it might mean that it needs to be replaced. For example, creaking or grinding noises usually mean that the bearings or other parts of the crank are starting to wear down.
Wobbling or Seems Loose
A wobbling or loose bike crankshaft is another indication that it needs to be replaced. This generally signals that the bearings are wearing out and that the crank must be changed.
Damaged or Bent
The bike crank must be replaced if it is damaged or bent. This usually happens because of an accident or crash, but it can also occur if the bike is ridden over rough terrain.
Old and Worn Out
Even if the bike crank is not showing any signs of wear or damage, it may still need to be replaced if it is old and worn out. Over time, the materials in the crank can start to break down and degrade, affecting the bike’s performance.
If you think your bike crank may need to be replaced, it’s best to take it to a bike shop or mechanic to have it checked out. They will be able to tell you for sure if the crank needs to be replaced and can help you find a suitable replacement for your bike.
How to Remove Bike Crank Without Puller? Step-by-Step Guide
This can be done by using a vise and some brute force. You will also need a socket wrench and an adjustable wrench. Follow these steps to remove your bike crank without any trouble!
Step 1: Release the Pedals
First, loosen the pedals from the crank arms. You can do this by unscrewing the left pedal and pulling it out, then doing the same with the right pedal.
Step 2: Remove the Crank Arms
Next, support the bottom bracket with one hand so it doesn’t fall out when you remove the crank arms.
Step 3: Take out the Bolts
Use a socket wrench to remove the bolts that hold the crank arms in place. There are usually two bolts per arm – one on the inside and one on the outside.
Step 4: Pops Off
Once the bolts are separated, gently tap on the end of each crank arm until it pops off the spindle. If it’s being stubborn, you can use an adjustable wrench to help pry it off.
Step 5: Finishing
With the crank arms removed, the bottom bracket will be the only thing left attached to the bike frame. Use an adjustable wrench to loosen the bolts holding it in place, then take it out from the frame.
How Do You Choose the Right Bike Crank for Your Bike?
There are a few things to consider when choosing the right bike crank for your bike. Here are a few things to keep in mind:
Type of Bike You Have
There are different types of cranks for different kinds of bikes. For example, a road bike will need another kind of crank than a mountain bike.
Size of the Bike
The size of the bike will also dictate the type of crank you need. A smaller bike will need a smaller crank, while a larger one will need a larger one.
Your riding style will also dictate the type of crank you need. For example, if you are a casual rider, you will need a different kind of crank than a competitive rider.
Your budget will also dictate the type of crank you need. There are different types of cranks available at various price points.
Once you have considered all of these factors, you should be able to narrow down your choices and find the right bike crank for your bike.
What Are the Different Types of Bike Cranks?
There are many different bike cranks, each with advantages and disadvantages. Here are some of the most common types:
The most popular type of crank is the conventional one. They are easy to use and last a long time. They work well with most bottom bracket standards, although they aren’t as light or powerful as other cranks.
On road bikes, compact cranks are becoming increasingly popular. They’re lighter and more durable than standard cranks, allowing for a smaller chainring. However, they do not fit all bottom bracket threads.
Steel or aluminum BMX cranks are designed for strength and durability and are frequently seen on BMX racing bikes. They’re usually constructed of steel or aluminum and come in several sizes.
Mountain Bike Cranks
A mountain bike crankset has three chainrings, most commonly having double chains and a triple (three rings) configuration. They are generally constructed of aluminum or steel and frequently include reinforcements in the spider arms to accommodate the additional loads of mountain biking.
Single Speed Cranks
There are many different single-speed cranks available. They come in various lengths and materials, like steel or aluminum. Some have reinforced spider arms.
Kids’ Bike Cranks
These are available in a variety of lengths and materials. Steel or aluminum is used to make them and may include reinforced spider arms.
Frequently Asked Questions
1. What if my bike doesn’t have a shimano crankset?
If your bike doesn’t have a Shimano crankset, you’ll need to use a crank puller to remove the crank arm. Most bike shops sell crank pullers, and they’re relatively inexpensive.
2. What if my crank arm is stuck on the spindle?
If your crank arm is stuck on the spindle, you can try tapping it gently with a mallet. You can also try heating the spindle with a hair dryer or heat gun.
3. Does bike crank length matter?
It depends on several factors, such as your bike, riding style, and personal preferences.
For example, some riders believe that a shorter crank length can provide a more efficient pedaling stroke, while others find that a longer crank length offers more power and stability. Ultimately, it is up to you to experiment with different crank lengths to see what works best for you.
