How To Take A Link Out Of Chainsaw Chain Step-by-Step

Can you fix a chainsaw chain by removing a link? Yes, you can fix a chainsaw chain by removing a link, especially if a rivet is damaged or a section of the chain is bent. This process is a key part of chainsaw chain repair and can extend the life of your cutting tool. Knowing how to remove chainsaw link sections is a valuable skill for any chainsaw owner. This guide will walk you through the entire process of chainsaw chain disassembly safely and effectively, helping you with broken chainsaw chain fix needs.

Chainsaws are powerful tools, and their chains are the heart of their cutting ability. Over time, or due to an accident, a chainsaw chain can become damaged. Sometimes, a single damaged link is the culprit, making the chain unsafe or inefficient. Instead of immediately buying a new chain, you might be able to perform a chain saw link repair. This often involves removing the damaged link and rejoining the chain. This guide will detail how to take a link out of a chainsaw chain, a crucial step in chainsaw chain maintenance. We will cover everything from identifying the problem to rejoining the chain, making chainsaw chain disassembly and reassembly a manageable task. We will also touch upon when it might be better to replace chainsaw chain link altogether.

Identifying a Damaged Link

Before you can remove chainsaw link sections, you need to know which link is the problem. Look closely at your chainsaw chain. Are there any signs of wear or damage?

Common Signs of Damaged Links:

Bent or Twisted Links: If a link appears out of shape, it’s likely damaged. This can happen if the chain hits something hard, like a rock or metal.
Cracked Rivets: The rivets hold the links together. If you see a crack around a rivet, that section of the chain is compromised.
Stretched or Worn Plates: Over time, the metal plates can stretch, making the chain loose. While this usually requires tightening, a severely stretched section might need removal.
Missing Rivets: If a rivet is completely gone, the chain is no longer safely joined.
Burnt or Overheated Links: A chain that has been run without proper lubrication can overheat, leading to discolored or brittle metal.

A damaged link can cause the chain to snag, jump off the bar, or break completely. It’s essential to address these issues promptly for safety and to prevent further damage to your chainsaw.

Tools You’ll Need for Chainsaw Chain Repair

Performing this kind of chainsaw chain maintenance requires specific tools. Having the right equipment makes the job much easier and safer.

Essential Tools:

Chainsaw Chain Breaker Tool: This is the most crucial tool. It’s designed to push out the rivets that hold the links together. Manual and hydraulic versions are available.
Vise or Clamp: To hold the chain steady while you work. A sturdy vise is ideal.
Hammer: For gently tapping the chain breaker tool.
Pliers (Needle-nose and regular): For gripping small parts and manipulating the chain.
Safety Glasses: Always protect your eyes when working with tools and metal.
Gloves: To protect your hands from sharp edges and grease.
New Rivet (if rejoining): If you are removing a link and plan to rejoin the chain, you’ll need a new, compatible rivet. These are often sold in kits.
Chain File or Grinding Tool: To smooth any rough edges after rejoining.
Rivet Spinner or Bucking Bar (for certain chains): Some chains, especially those with drive links and tie straps, might require a special tool to re-buck the rivets.

Having these tools readily available will ensure a smooth and efficient chainsaw chain repair process.

Step-by-Step Guide to Removing a Chainsaw Link

This process requires precision and patience. Follow these steps carefully for successful chainsaw chain disassembly.

Step 1: Secure the Chain

First, you need to safely remove the chainsaw chain from the chainsaw bar. Always ensure the chainsaw is off and the spark plug wire is disconnected to prevent accidental starting.

Loosen the tensioning mechanism on your chainsaw.
Slide the chain off the bar and drive sprocket.
Once the chain is free, place it on a sturdy workbench. Secure a section of the chain containing the damaged link in a vise. Ensure the damaged link is easily accessible.

Step 2: Locate the Rivet to Remove

Examine the damaged link. Chainsaws have a specific rivet that holds each link in place. You need to identify the rivet that connects the damaged section to the rest of the chain.

Most chainsaw chains have a pattern of drive links, tie straps, and cutter links.
When you remove chainsaw link sections, you are typically separating a tie strap from a drive link or vice-versa.
The rivet you need to push out is usually on the side of the chain that connects two plates.

Step 3: Use the Chain Breaker Tool

This is where the specialized chain breaker tool comes into play.

Position the chain breaker tool so that its pushing pin aligns with the center of the rivet you want to remove.
Ensure the chain is held firmly in the vise, with the rivet accessible to the tool.
Gently turn the handle of the chain breaker tool. This will slowly push the rivet out of the chain link.
Important: Do not try to push the rivet all the way out if you plan to rejoin the chain later. You only need to push it out enough to separate the link. If you are discarding the entire section, push the rivet completely out.

Here’s a table illustrating the process:

Action	Tool Used	Key Consideration
Loosen chain tension on saw	Chainsaw wrench	Ensure saw is off, spark plug disconnected.
Secure chain in vise	Vise	Hold chain firmly, with damaged link accessible.
Align chain breaker pin with rivet	Chain breaker tool	Ensure pin is centered on the rivet head.
Push rivet out	Chain breaker tool	Turn handle slowly; stop if rejoining, push completely if discarding section.

Step 4: Separate the Damaged Link

Once the rivet is loosened or removed, you can carefully separate the damaged link from the chain.

If the rivet is partially out, you may be able to use pliers to gently pull the link plates apart.
If the rivet is fully removed, the link should come apart easily. Be careful of sharp edges.

You have now successfully performed chainsaw chain disassembly for a specific link.

Rejoining the Chain (If Necessary)

If you’ve removed a damaged link and the chain is now too short, or if you are performing a broken chainsaw chain fix, you might need to rejoin it. This usually involves adding a new connecting link or re-bucking an existing rivet. For simplicity, we’ll focus on using a connecting link.

Step 5: Prepare for Rejoining

You will need a connecting link, which typically consists of two outer plates and a rivet pin. These are often sold as part of a chainsaw chain repair kit.
Ensure the two ends of the chain you are joining are clean and free of burrs.

Step 6: Position the New Link

Align the open ends of the chainsaw chain with the new connecting link.
The new link will have a rivet pin. You need to position this pin through the holes in the chain links.

Step 7: Re-buck the Rivet

This is a critical step and requires precision. Re-bucking involves creating a new head on the rivet pin to securely hold the links together.

Using a Chain Breaker Tool with a Bucking Feature: Some advanced chain breaker tools have a bucking feature designed for this purpose. Follow the tool’s specific instructions.
Using a Rivet Spinner or Bucking Bar: Place the chain on a flat surface. Position the rivet spinner or bucking bar over the protruding rivet pin.
Carefully tap the spinner or bar with a hammer. The goal is to mushroom the end of the rivet pin, forming a secure head that locks the link. Do this gradually and evenly on both sides if applicable.
Crucial: Do not over-buck the rivet, as this can make the link stiff or break it. Conversely, under-bucking will result in a loose connection.

This is a delicate part of chainsaw chain disassembly and reassembly.

Step 8: Test the New Connection

After re-bucking, check the joint. The new link should move freely, just like the other links in the chain.
If the link is stiff, you may need to gently tap it with a hammer or use a chain file to smooth any rough areas around the rivet.
If the rivet is loose, you may need to carefully re-buck it.

Reassembly and Testing

Once you have performed the chain saw link repair and rejoined the chain, it’s time to put it back on the chainsaw and test it.

Step 9: Reinstall the Chain

Place the repaired chain back onto the chainsaw bar and drive sprocket.
Tension the chain correctly according to your chainsaw’s manual. The chain should be snug enough not to sag off the bar but loose enough to be pulled by hand (with gloves on).

Step 10: Test the Chainsaw

With the chain properly tensioned, carefully start the chainsaw.
Listen for any unusual noises or vibrations.
Test the chain on a piece of scrap wood. Observe how it cuts and if the repaired link functions smoothly.
If the chain feels rough or binds, shut off the chainsaw, disconnect the spark plug, and re-examine the repaired link. You may need to adjust the rivet or smooth the link.

If the repaired link causes problems, it might be better to replace chainsaw chain link sections or the entire chain.

When to Consider Replacing the Entire Chain

While removing a link for chainsaw chain repair can be effective, there are times when it’s better to replace the entire chain.

Reasons to Replace the Chain:

Multiple Damaged Links: If you find several damaged links, it’s often more cost-effective and safer to replace the whole chain.
Excessive Wear: If the chain is generally worn out, with stretched cutters and tie straps, a single repair won’t restore its full capability. Look for signs of chain stretch by trying to pull the chain up from the bar; if you can pull it up more than a quarter-inch in most places, it’s likely worn out.
Damage to Cutter Teeth: If the cutting teeth themselves are chipped, dull beyond sharpening, or broken, the chain needs replacement.
Repeated Breakage: If you’ve had to repair the chain multiple times, it indicates underlying weakness, and a new chain is a safer bet.
Improper Rejoining: If you are unable to properly rejoin the chain, or if the repaired link is consistently problematic, it’s time for a new chain.

Knowing when to remove chainsaw link sections versus when to replace chainsaw chain link is part of good chainsaw chain maintenance.

Pro Tips for Chainsaw Chain Maintenance

Regular maintenance can prevent damage and reduce the need for repairs.

Keep it Sharp: A sharp chain cuts efficiently and puts less stress on the components. Sharpen your chain regularly.
Proper Lubrication: Ensure the chain oiler is working correctly and the chain is adequately lubricated. This reduces friction and heat buildup, which can damage links.
Correct Tension: Always maintain the correct chain tension. A loose chain can derail and cause damage, while an overly tight chain causes excessive wear.
Cleanliness: Keep the chain, bar, and sprockets clean. Sawdust and debris can interfere with the chain’s movement and cause premature wear.
Inspect Regularly: Before and after each use, inspect your chain for any signs of damage or wear.

By following these tips, you can minimize the need for chainsaw chain disassembly and prolong the life of your cutting equipment.
