If the mountain bike you possess has a broken chain, you should waste no time in getting another chain. Nevertheless, there are chances that you can fix the damaged chain with the help of a chain tool. This is precisely the reason why mountain bike riders keep a chain tool whenever they go out on their mountain bikes.
Bike's chain contains three main parts: side plates made of metal, rollers inside side plates, and pins that bind rollers and plates together. The main function of these pins is to let the rollers rotate when the chain traverse around the cogs.
In case the chain gets broken, all you need to do is to replace the link which is broken with an extra link. If you don't have an extra link, take out the damaged link and attach the open ends of chain and ride your bike on an undersized chain until you get a chance to repair it.
Use a chain tool to remove the broken link. You have to put it inside the chain tool and rotate the tool in counter clock direction until the pin in chain tool get in touch with the chain rivet. Keep rotating the tool until pin is pushed out from the roller.
Now you should rotate the tool in opposite direction, and take it out from the roller. Place the tool on the floor and take out side plates on the inside and the roller.
After this you need to readjust the chain. It is important to have a chain tool for retaining the chain or some external support to grip the chain, if you want to repair and readjust the chain.
Once the broken link is taken out and the chain has been readjusted, next step is to join the chain links that were earlier joined with the damaged link; otherwise, you may put a new link if you have one.
Doing it yourself for the first time will not be easy. Hence, it is better to ask someone to show the process and make you aware about how it's done. Later you can try yourself with the help of a chain tool and a chain. After you have seen someone doing it and you have practiced it yourself, you will feel at ease while repairing the chain of a mountain bike.
