How to Fix a Broken Motorcycle Chain: A Step-by-Step Guide for Riders

Few roadside breakdowns are as daunting for a rider as a snapped motorcycle chain. It halts your journey instantly. However, with the right knowledge and tools, fixing a broken chain is a manageable task. This guide provides a clear, step-by-step process to get you safely back on the road.

Essential Tools and Safety First

Before starting, ensure your motorcycle is on a stable center stand or paddock stand. You will need a chain breaker tool, a new master link (or connecting link) specific to your chain’s size and type (e.g., 520, 525), a pair of master link pliers (circlip pliers), and a small hammer. Always wear gloves to protect your hands.

Step-by-Step Repair Process

1. Assess and Remove the Damaged Section: Locate the broken link. Use the chain breaker tool to push out the rivets on the damaged links, removing the broken section. Keep the old, good links aside in case you need them.

2. Prepare the New Master Link: Your new master link kit includes a side plate with two pins, a separate side plate, two O-rings, and a clip (for clip-style links). Slide the new link’s pins through the ends of the good chain on your bike.

3. Secure the Master Link: Place the O-rings over the pins (if applicable), then align and press the second side plate onto the pins. For a clip-style link, secure the spring clip into the grooves on the pins, ensuring the closed end faces the direction of chain rotation.

4. Check Alignment and Tension: Manually rotate the rear wheel to check the link moves freely through the sprockets. Finally, adjust your motorcycle chain tension to the manufacturer’s specified slack.

Common Questions Answered

Q: Is this a permanent fix?
A: A properly installed quality master link is a reliable repair. However, it’s wise to plan for a full chain and sprocket replacement soon, as a break often indicates general wear.

Q: Can I reuse the old master link?
A> Never reuse a master link. Always install a new, matching link for safety and reliability.

Prevention is Key

Regular maintenance prevents most breaks. Clean and lubricate your chain frequently, check for proper tension, and look for signs of wear like stiff links, rust, or stretching. For a comprehensive visual guide on this entire process, you can learn more about How To Fix A Broken Motorcycle Chain.
