How to Fix a Broken Bike Chain: A Step-by-Step Guide

Assessing the Damage


Assessing the Damage

If you are an avid cyclist, you know that a broken chain can put an abrupt halt to your ride. However, fixing a broken chain is not as difficult as it may seem, and you can easily perform this repair with a few simple tools. Before fixing the chain, though, you must determine the extent of the damage.

First, assess the damage to the chain. If the chain has snapped in half, you will need to remove the damaged section of the chain and reconnect the two remaining pieces together. In comparison, if the chain has a missing link, then you only need to find a replacement link to attach it.

The next thing to look for is the condition of the broken link or links. If the link is bent out of shape, you can manually straighten it out using a pair of pliers. However, if the link is visibly damaged or badly worn, it is best to replace the entire link or chain to ensure the bike’s safety the next time you ride it.

Once you have assessed the damage, take a look at the surrounding components of the chain, such as the derailleur, chainring, and cassette. These components can often get damaged when a chain breaks, so it’s best to check them over to ensure they are still functioning correctly.

You should also pay attention to the tension of the chain after you have reassembled it. An overly slack or tight chain can cause the bike to shift poorly and can even make the bike unsafe to ride. The chain should have a bit of slack in it, but not too much that it sags or too little that it is stretched tight. You can check the tension of the chain by pulling it away from the largest chainring and seeing how far it extends. If it is hanging too low, you can tighten it by adjusting the tension of the derailleur.

By assessing the damage to your bike’s chain, you can determine the best way to proceed with fixing it. Whether you need to replace a broken link or replace the entire chain, doing so will help you get back on the road safely.

Finding Replacement Links


Finding Replacement Links

If you have a broken chain, it is necessary to replace the damaged links to restore the chain to its original working state. Finding the right replacement links can be daunting, especially if you’re unaware of the chain’s type, size, and pitch. Fortunately, there are several ways to find the right replacement links for your broken chain.

The first and foremost thing to do is to identify the type, size, and pitch of the chain. You will find this information printed on the chain, typically on one of the links. The type of chain refers to the design of the links, and there are various types of chains such as O-Ring chain, Roller chain, and X-Ring chain, among others.

The size and pitch of the chain also vary depending on the type of chain. The size indicates the width of the chain, whereas the pitch refers to the distance between the pins. It is essential to have this information because it will help you determine the right replacement link to choose from.

The easiest way to find replacement links is to visit a local motorcycle shop. They will have a wide range of options available and can assist you in selecting the right one for your broken chain. It is always recommended to bring the old chain with you to get an exact match for size and pitch. This way, you can be sure that the new replacement links will fit and function correctly.

If you cannot find a local motorcycle shop, you can also try searching online for replacement links. Many online retailers specialize in motorcycle parts and accessories, making it easier to find the right replacement links. However, it is essential to ensure that the retailer you choose is reputable and sells high-quality replacement links.

Another option is to contact the chain manufacturer directly. Most manufacturers have a customer service line or email that you can use to inquire about replacement links. They will be able to provide you with the necessary information and assist you in finding the right replacement links for your broken chain.

It is vital to ensure that the replacement links you choose are of the same type, size, and pitch as the original chain. Using replacement links that do not match the original chain can cause compatibility issues and could compromise the safety of your motorcycle. Therefore, it is crucial to take the time to find the right replacement links.

When you have found the right replacement links, you will need to remove the damaged links from the chain and install the new ones. This process can be challenging and requires special tools such as a chain breaker and rivet tool. If you are not confident in your ability to perform this task, it is best to consult a professional mechanic.

To conclude, finding the right replacement links for a broken chain is crucial to ensure the safety and proper functioning of your motorcycle. Identifying the type, size, and pitch of the chain is the first step in finding the right replacement links. Visiting a local motorcycle shop, searching online, or contacting the chain manufacturer are all viable options to find replacement links. It is essential to ensure that the replacement links you choose match the original chain’s type, size, and pitch to avoid compatibility issues.

Breaking the Chain


Broken Bike Chain

A broken chain can be a huge inconvenience for a cyclist. It not only slows down the ride, but can also leave the rider stranded in the middle of nowhere. Fixing a chain is a skill that every cyclist should know, and it’s not as difficult as it may seem. In this article, we will guide you through the process of fixing a broken bike chain in three easy steps.

Tools you’ll need:


Bike Chain Tools

To fix a bike chain, you’ll need some specific tools. Here’s a list of the tools you’ll need:

  • Chain tool: This is a small device that you’ll use to break the chain apart.
  • Pliers: You’ll need pliers to remove the pin from the chain link.
  • A spare link: You’ll need a spare link to replace the broken one.

Step 1: Remove the broken link


Removing Bike Chain Link

The first step is to remove the broken link from the chain. To do this, place the chain tool on the chain pin with the arrow facing towards the broken link. Apply pressure to the tool’s handle to push the pin out of the link. Remove the chain tool and push the broken link out of the chain.

Step 2: Replace the broken link

Now that the broken link has been removed, it’s time to replace it with the spare link. Take the spare link and insert the chain pin into one of the links that’s still intact. Use the pliers to push the pin into the link until it’s flush with the other side of the link.

Step 3: Reconnect the chain


Reconnecting Bike Chain

The final step is to reconnect the chain. Place the chain tool on the chain pin that you just installed and apply pressure to push the pin into the link. Remove the chain tool and your chain is fixed!

It’s important to ensure that the chain pin is pushed all the way into the link to prevent the chain from breaking again. If you’re still having trouble with your chain after attempting to fix it, it might be time to take your bike to a professional mechanic to have it checked.

Now that you know how to fix a broken bike chain, you’ll be able to get back on the road in no time. Keep in mind that prevention is always better than cure, so make sure to take good care of your bike chain by keeping it clean and well lubricated to minimize the risk of it breaking in the first place.

Installing the New Link


Installing the New Link

Now that you have removed the broken link, it’s time to install the new link. Here’s how you can do it:

Step 1: Match the new link to the old one. You need to make sure that the new link is the same as the old one, otherwise, it won’t fit properly into the chain. It’s essential that you use a chain link that matches the width and style of your existing chain.

Step 2: Insert the new link into the chain. First, you need to attach one of the open ends of the new link to the adjacent link in the chain. Do this by inserting the link pins through the holes on both sides of the link. Then, use the chain tool to push the link pins into place, ensuring that they are flush with the outer edge of the link.

Step 3: Insert the second pin. After attaching one open end of the new link to the adjacent link in the chain, you can then insert the second pin into the other open end of the new link. Make sure to line up the holes on both sides of the link correctly. Then, press the pin into place using the chain tool. Once again, make sure that the pin is flush with the outer edge of the link.

Step 4: Check the link. After installing the new link, it’s important to check that it’s seated correctly. You can do this by flexing the chain at the new link to ensure that it moves freely and doesn’t bind. Also, check that the link pins are correctly positioned and don’t protrude on either side of the link.

Step 5: Test ride. The final step is to test your newly repaired chain by taking a short test ride. Check if the chain runs smoothly and that the new link doesn’t cause any issues. If everything seems fine, you can then proceed to clean your bicycle and get back to riding it normally.

Remember that fixing your chain is a temporary solution and you might want to consider getting a new chain if this happens often. It’s advisable to conduct regular maintenance checks on your bicycle to prevent future problems and ensure its longevity.

Testing the Chain


Testing the Chain

Before attempting to fix a broken chain, it is important to determine if the chain is indeed broken. This can be done by a simple visual inspection or by physically testing the chain. In this section, we will discuss the various methods that can be used to test the chain.

The first method of testing the chain is by performing a visual inspection. Look for obvious signs of damage or wear on the chain, such as bent or broken links, rust or corrosion, or excessive stretching. If any of these signs are present, it is likely that the chain is broken and needs to be repaired or replaced.

The second method is to pull on the chain to check for any deformities. If the chain is not straight, it could be broken or have a damaged link. Be careful not to put too much force on the chain, as this could cause further damage.

The third method is to flex the chain sideways to check for any binding or kinking. If the chain binds or kinks, it could be a sign of a broken or damaged link. This method is especially useful for detecting smaller cracks or breaks in the chain.

The fourth method is to check the tension of the chain. If the chain is loose or sagging, it may have stretched or have a broken link. Adjust the tension of the chain and check it again after a few minutes. If the tension has loosened again, it is likely that the chain needs to be replaced.

The fifth and final method is to use a chain checker tool. A chain checker is a device that measures the amount of stretch in the chain. If the chain has stretched beyond the recommended level, it is likely that it needs to be replaced. This method is particularly useful for detecting wear on the chain that may not be visible to the naked eye.

In conclusion, testing the chain is an essential step in fixing a broken chain. By using a combination of visual inspection and physical testing methods, you can determine if the chain is indeed broken and needs to be repaired or replaced. Remember to always exercise caution when testing the chain, and seek professional help if you are unsure about the condition of the chain.
