3 Easy Steps To Break A Bike Chain

How To Break A Bike Chain

Find the broken link: Find out which part of the chain needs to be broken in order for the mission to be finished. I strongly suggest you pick a connection that is already broken or shows clear indications of wear and tear.

Position the chain tool: Place the chain on the chain tool, and then check that the pin on the tool is aligned with the rivet that you want to remove on the chain. Be sure that the chain is correctly engaged with the driving mechanism of the tool.

Break the chain: It needs a gentle push in the right direction right now. If you turn the chain tool’s handle clockwise, you’ll apply some force, which will push the pin out of the chain link. Keep turning the nut until the pin is completely pushed out of the chain’s hole. When that happens, the chain will break into two separate pieces. Yay, you did it!

Rejoining The Chain

If you need to reconnect the chain later, you can use a quick link or master link, if your chain has one. These are links that make putting the chain back together easy without a chain tool.

But if your chain doesn’t have a quick link, you’ll have to rejoin it with a chain pin or a special replacement pin that often comes with chain tools.

Problems You May Face While Breaking Chain

When a bike chain breaks, a lot of bad things could happen. Here are some usual problems and what to do about them.

Difficulty In Aligning The Chain Tool

Aligning the chain tool with the chain link can be a little tricky at times. Try the following if you’re having trouble:

  • Make sure the pin on the chain tool lines up with the point on the chain link you want to take off.
  • Make sure that the part of the chain tool that drives the chain is firmly connected to the chain.
  • Put light pressure on the handle and slowly turn it to keep it from getting out of place or moving.

Pin Not Fully Coming Out

Sometimes, the pin won’t come out of the chain link all the way, leaving a small piece still in place. To take care of this problem:

  • Examine the pin to check if it is stuck or if it moves readily. If it’s stuck, try putting a little lube on it to help it move.
  • Make sure the pin is fully pushed out by applying steady, even pressure as you turn the chain tool’s handle.
  • If the pin still won’t come out all the way, you can carefully tap it out from the other side with pliers or a small hammer.

Accidental Removal Of Wrong Chain Link

It’s important to know which link in the chain to break. But mistakes can happen, and you might remove the wrong link by accident. If this takes place:

  • Using the chain tool, reattach the pin to the chain link that you accidentally took out of the chain when you were working on it.
  • Put light pressure on the handle and turn it until the pin is all the way in.
  • Check again and find the right link to break, then do the process again.

Final Words

It might sound scary to break a bike chain, but with the right tools and a little practice, you’ll be able to do it like a pro. Use a chain tool that is the right size for your chain and take your time to line it up with the link you want to remove.

Keep in mind that regular repair is the best way to keep your bike chain and bike as a whole in good shape. Clean and lube your chain often, check it for wear, and if it’s worn out, replace it. If you ever don’t know what to do or need help, don’t be afraid to ask a trusted rider for advice.

So, my friend, stay positive, take it step by step, and enjoy the feeling of success when you’ve successfully taken your bike chain apart and put it back together. Have fun riding, and keep that chain in good shape.
