How to Fix a Broken Motorcycle Chain: A Step-by-Step Guide for Riders
A snapped motorcycle chain is more than an inconvenience; it’s a road-side emergency that can leave you stranded. Knowing How To Fix A Broken Motorcycle Chain is an essential skill for every rider. This guide provides a clear, professional procedure to get you safely back on the road.
Essential Tools for Chain Repair
Before you start, gather these tools: a motorcycle chain breaker/riveting tool, a new master link (or connecting link) specific to your chain size (e.g., 520, 525), a replacement chain section (if needed), circlip pliers, and basic wrenches. Never use a mismatched master link, as it compromises safety.
Step-by-Step Repair Process
1. Secure the Bike and Assess Damage: Place the bike on a center stand. Examine the broken chain links. If only one link is damaged, you may only need to remove a short section.
2. Remove the Damaged Section: Use the chain breaker tool to push out the pins on the damaged links. Remove the broken pieces, leaving two good ends.
3. Install the New Master Link: Connect the chain ends with the new master link. Slide the link plate onto the two pins, followed by the rubber O-rings (if your chain has them), and then the second side plate.
4. Secure the Master Link: For a clip-style link, secure the circlip with circlip pliers, ensuring the closed end faces the direction of chain rotation. For a rivet-style link, use the riveting tool to carefully mushroom the pin ends, following the tool’s instructions precisely.
Post-Repair Safety Check and Adjustment
After repair, check chain tension according to your motorcycle’s manual. A chain that is too tight or too loose can cause rapid wear or another failure. Lubricate the chain thoroughly, especially at the new link.
Frequently Asked Questions (FAQ)
Q: Can I repair a chain without a breaker tool?
A: A proper repair requires a chain breaker/riveter for safety. Temporary fixes are highly dangerous and not recommended.
Q: How do I know my chain size?
A: Check your owner’s manual or look for markings (like 520) on the side plates of your old chain.
Q: Should I replace the entire chain after a break?
A> It is often recommended, as a break indicates significant wear. For a relatively new chain, a single-section repair with a quality tool is acceptable.
