Remove Old Chain: Use a chain tool or improvised method to push out the chain pins and separate the old chain
To remove an old bike chain without a chain tool, you'll need to improvise with items you likely have around the house. One effective method is to use a combination of a hammer and a punch. First, place the chain on a solid surface, such as a workbench or a piece of wood. Identify the chain pin you wish to remove and position the punch directly over it. Using the hammer, gently tap the punch to drive the pin out of the chain. Be careful not to use too much force, as this can damage the chain or the surface beneath it.
Another improvised method involves using a bike pump. If your bike pump has a Schrader valve, you can use the valve's spring mechanism to push out the chain pins. Simply insert the pin into the valve's hole and use the pump's handle to compress the spring, which will force the pin out. This method requires a bit of finesse to avoid damaging the chain, but it can be quite effective.
For those who prefer a more mechanical approach, you can use a pair of pliers and a small flathead screwdriver. Position the pliers around the chain pin and use the screwdriver to pry the pin out. This method can be a bit more labor-intensive but offers better control over the removal process.
Regardless of the method you choose, it's important to work slowly and carefully to avoid damaging the chain or injuring yourself. Once you've removed the old chain, you can proceed with splicing in the new one using similar improvised techniques.
Remember, while these methods can be effective in a pinch, investing in a proper chain tool can make the process much easier and safer in the long run.

Clean and Inspect: Thoroughly clean the bike's chainring and sprockets, checking for wear or damage
Before splicing a bike chain without a chain tool, it's crucial to ensure the chainring and sprockets are in good condition. Begin by thoroughly cleaning these components to remove any dirt, grime, or debris that could interfere with the splicing process or the chain's performance. Use a degreaser and a brush to scrub the chainring and sprockets, paying close attention to the teeth and the areas where the chain makes contact. After cleaning, rinse the components with water and dry them completely to prevent rust or corrosion.
Once the chainring and sprockets are clean, inspect them for signs of wear or damage. Look for any bent or broken teeth, as these can cause the chain to skip or derail. Check the chainring for any cracks or stress marks, and ensure that the sprockets are not excessively worn. If you notice any damage, it's best to replace the affected component before proceeding with the chain splicing.
When inspecting the chainring and sprockets, also take note of the chain's alignment. Ensure that the chain is properly seated on the teeth of both components, and that it runs smoothly without any kinks or twists. If the chain is misaligned, you may need to adjust the derailleur or the chain tension before splicing.
In addition to cleaning and inspecting the chainring and sprockets, it's important to lubricate the chain to ensure smooth operation. Apply a small amount of chain lube to each roller of the chain, and allow it to penetrate for a few minutes before wiping off any excess. This will help to reduce friction and wear, and will improve the overall performance of the bike.
By thoroughly cleaning and inspecting the chainring and sprockets, and by ensuring that the chain is properly aligned and lubricated, you can help to ensure a successful chain splicing process. This will not only improve the performance of your bike, but will also extend the life of the chain and other components.

Install New Chain: Thread the new chain through the derailleur and around the chainring and sprockets
Begin by ensuring your bike is securely positioned, either by using a bike stand or flipping it upside down so the wheels are in the air. This will provide stability and make it easier to access the chain and derailleur. Next, locate the derailleur, which is the mechanism that shifts the chain across the different gears on the rear wheel. It's typically found on the right side of the bike, attached to the frame near the rear wheel.
Once you've located the derailleur, carefully thread the new chain through it. Make sure the chain is properly aligned with the jockey wheels, which are the small wheels on the derailleur that guide the chain. You may need to use your fingers or a small tool to help guide the chain through the derailleur.
After threading the chain through the derailleur, pull it around the chainring and sprockets. The chainring is the large gear attached to the pedals, and the sprockets are the smaller gears on the rear wheel. Make sure the chain is properly seated on the teeth of the chainring and sprockets, and that it's not twisted or kinked.
As you're installing the new chain, it's important to keep it taut. This will help ensure that it's properly aligned and seated on the gears. You may need to adjust the tension of the derailleur cable to achieve the right amount of slack in the chain.
Once the chain is properly installed, test it by pedaling the bike and shifting through the gears. Make sure the chain shifts smoothly and doesn't slip or make any unusual noises. If you encounter any issues, double-check that the chain is properly seated on the gears and that the derailleur is functioning correctly.
Remember, when splicing a bike chain without a chain tool, it's crucial to be patient and take your time. Properly installing a new chain requires attention to detail and a bit of finesse, but with the right approach, you can have your bike up and running smoothly in no time.
