Roller chains are an essential part of a wide variety of mechanical equipment for the efficient transmission of power and motion. However, in some cases, you may need to shorten the roller chain to suit a specific application. While this may seem like a complicated task, shortening roller chains can be a simple process with the right tools and knowledge. In this blog we will give you a step by step guide on how to properly shorten your roller chain.
Step 1: Gather Necessary Tools and Materials
To successfully shorten your roller chain, you will need the following tools and materials:
1. Chain tool or chain breaker
2. Chain rivet puller
3. Bench vise
4. Hammer
5. New connectors or rivets (if required)
6. Goggles and gloves
Having these tools at the ready will ensure the process runs smoothly and everything you need is within easy reach.
Step 2: Measure the desired chain length
Before shortening your roller chain, you need to determine the length you need for your particular application. Use a measuring tape to measure and mark the desired length on the chain to make sure the measurement is accurate. Make sure to account for any tension adjustments that may be needed.
Step 3: Secure the Chain in a Bench Vise
For convenience and stability, secure the roller chain in a vise. Place the marked link between the vise jaws, making sure to apply equal pressure on both sides.
Step Four: Remove Unnecessary Links
Using a chain tool or chain breaker, align the tool’s pin with the roller on the connecting link of the chain you want to remove. Apply firm pressure or tap lightly with a hammer to push the pin out. Remember, you don’t need to completely remove the adjacent pin; just remove it. Only the ones you tagged.
Step 5: Assemble the Chain
If you have shortened the chain with an uneven number of links, you will need to attach the links or rivets to complete the assembly. Use a chain rivet extractor to remove the pin from the connecting link, creating a hole. Insert new connecting links or rivets into the holes and secure them with a chain tool or chain breaker.
STEP 6: INSPECT AND LUBRICATE THE CHAIN
After shortening your roller chain, take a moment to inspect it thoroughly. Make sure all pins, rollers and plates are in good condition with no signs of damage or wear. Lubricate your chain with a suitable lubricant to minimize friction and prolong its life.
Shortening roller chains may seem daunting at first, but by following this step-by-step guide and using the proper tools, you can easily and successfully complete the task. Remember to be cautious throughout, wear protective gear and make safety a priority. Properly shortened roller chains not only guarantee the smooth operation of machinery, but also improve performance and efficiency.
