Firstly, you’ll need to gather the right tools, including a chain breaker tool, pliers, and a quick link. Having everything before you start is essential so you won’t have to stop midway.

The process might take a few minutes, so be patient and apply steady pressure until the pin comes out.

Match the new chain to the old chain length.

Counting the links in a chain may seem simple, but it’s an important step when replacing an old chain with a new one. Ensuring that the new chain has the same number of links as the old one is crucial for maintaining the functionality and safety of your equipment. In this blog post, we will discuss why counting the links in the old chain and breaking the new chain down to the same number of links is necessary.

Key Factors to Consider:


1. Chain length affects the functioning of your equipment


Having the right chain length is critical for ensuring the proper functioning of your equipment. If the chain is too long or too short, it can result in the ineffective operation of your machinery.

2. Compatibility with your equipment

Before purchasing a new chain, ensuring it is compatible with your equipment is important. Check the manufacturer’s specifications for chain compatibility.

3. The importance of correct installation
Installing a chain with the correct number of links is just as important as choosing the right chain. If the chain is not installed correctly, it can cause damage to your equipment or even pose a safety hazard to those operating it.
