Step by Step Guideline on How to Remove Cranks
There are some steps for removing Cranks which are given below:
1. Removing the Pedals:
At first, you have to separate the pedal from the crank arm by a wrench. The crank arm is the thing that which retains the pedals with the cranks. Set the wrench with the rod that connects the crank arm and pedal.
Next, rotate the wrench counterclockwise until it is being loosed from the crank arm. Then, Hold the pedal and turn the crank arm clockwise until the pedal is being separated from the crank arm.
When the right one is done, repeat the procedure on the other pedal. Both pedals have to be separated from the cranks for the next process and keep the pedals in a safe place so that you can re-install them after anytime you need.
2. Removing the Cap:
You have to open the cap from the middle of the crank if it has one. Generally, there are two types of caps (plastic or metal) that have on the cranks. For removing the lid, use a screwdriver. Set it in an edge of the cap and open it. Then the crank bolt will come out.
3. Loosening the pinch bolts:
If the crank has pinch bolts, you have to loosen it with a Hex key, which will allow you to remove the crank arm from the rest of the crankset. If your crank has these, insert a Hex key which will fit in the holes and turn the hex key counterclockwise. Untie the pinch bolts as you need.
4. Completely unscrewing the crank bolt:
After loosening the pinch bolts, you have to insert a Hex key in the crank bolt. And then you have to rotate it counterclockwise. Rotate Hex key’s handle counterclockwise until it’s completely separated from the crank.
You may have crank bolts on both sides. Go to the other side and unscrew the other one from the other crank. See the user manual of your bicycle or bike for knowing which key will be needed for this task. You can also purchase it from your nearby hardware shop, cycle shop, or from online.
5. Detach the Cranks without crank extractor:
If your bike’s cranks are self-extracting types, then it’s the last step for you to remove the cranks. You will easily be understood that what kinds of cranks are yours. You can recognize it by having only one crank bolt in your cranks.
If your cranks have only one crank bolt with a ring around it, then it’s self-extracting. Once you recognized it, just push the cranks away off the spindle and pull the crank away from the bicycle. Then go the other side of your bike and do the same thing. You have successfully removed your cranks.
6. Detach the Cranks with crank extractor:
It is the last step of removing the cranks from your cycle, whatever the cranks types are. This step is needed if your cycle has non-self-extracting cranks. You can easily recognize it. In this kind of cranks, there have crank bolts on each of the sides.
Firstly, you need a crank extractor. Buy a crank extractor from a bicycle store, hardware shop, or from online, which one you need. Put the extractor in the hole of the crank-bolt and rotate it clockwise until it’s tight.
Next, rotate the crank extractor counterclockwise until it’s removed. Then go another side of your bicycle and do whatever you did on the other side. That’s how you can easily remove your bicycle cranks.
