Removing links from a roller chain typically involves using a specialized tool called a chain breaker to press out a pin, allowing the link to be separated. This method is efficient and prevents damage to the chain components.
Using a Chain Breaker Tool
The most common and effective way to shorten a roller chain is by using a chain breaker tool. This tool is designed to precisely push the pin out of a link, effectively "breaking" the chain at that point.
Steps for Using a Chain Breaker
Here's a breakdown of the process:
- Position the Chain: Place the chain within the chain breaker tool, aligning the pin you want to remove with the tool's pusher pin. Ensure the anvil or support of the tool is correctly positioned under the link you intend to break.
- Align the Pusher: Make sure the tool's pusher pin is directly aligned with the center of the chain pin you wish to remove.
- Apply Pressure: According to the referenced video segment, you need to "push on the right [pin]" and "turn the crank" of the tool. This action pushes the tool's pin "onto the pin of the chain," forcing it out through the side plate. Turn the crank slowly and steadily.
- Break the Link: Continue turning the crank until the pin is pushed far enough through the side plate to free the link. You may need to push it completely out or just far enough to loosen the side plate.
- Separate the Chain: Once the pin is pushed out, the two ends of the chain at that link can be separated.
- Remove the Link: You have now successfully removed the link (or links) you intended to take out.
This method allows you to customize the length of the chain as needed for various applications, from bicycles to industrial machinery. Always ensure the tool is properly sized for your specific chain type and size.
Note: The referenced video highlights the core action: using the tool's crank to push the pin out. As stated, "it's very simple just turn the crank. And you're going to be pushing onto the pin of the chain."
