How to Fix a Loose Bike Crank
Riding a bike is a great way to get exercise, explore the outdoors, and even commute to work. But when your bike crank becomes loose, it can be a real hassle. You can hear the crank creaking, and it can make it difficult to pedal. Fortunately, fixing a loose bike crank is easy and only requires a few items. Here’s how to do it.
Tools You’ll Need
Before you start the process of fixing a loose bike crank, make sure you have the right tools on hand. You’ll need:
- A bike crank puller
- A wrench
- A set of Allen keys
- Bicycle grease
- A clean rag
Step 1: Remove the Crank
The first step is to remove the bike crank from the bike frame. To do this, use the bike crank puller tool. Insert the tool into the crank arm and turn it until it pops off the frame.
Step 2: Clean the Crank
Once the crank is off the frame, you’ll need to clean it. Use a clean rag and some bicycle grease to remove any dirt or debris that could be causing the crank to become loose.
Step 3: Tighten the Crank
Now that the crank is clean, you’ll need to tighten it. Use a wrench or a set of Allen keys to tighten the crank arm. Make sure it’s tight, but don’t over-tighten it.
Step 4: Reattach the Crank
Once the crank arm is tightened, you’ll need to reattach it to the frame. Use the bike crank puller to pop it back into place. Make sure it’s firmly attached to the frame.
Step 5: Test the Crank
The last step is to test the crank. Take the bike for a test ride to make sure the crank is firmly attached and isn’t making any noise. If everything is working correctly, you’re good to go.
