How to Remove and Install a Chainsaw Chain

Make your next chainsaw chain replacement fast and accurate with these professional chain replacement steps. 

Because it's a normal part of chainsaw use and ownership, knowing how to correctly change a chainsaw chain can save tool users time and money.

Even though the steps for a chain replacement are simple and can take less than five minutes, it's important to point out a few repair details that can make all the difference between a chain that's installed correctly and an incorrectly installed chain.

Of course, the first step toward a proper chainsaw chain replacement is getting a matching replacement chain for your chainsaw.

To learn how to match chainsaw chains for compatibility, please read our article: Chainsaw Chain Measurements, Sizes, and Types. Continue below for chainsaw chain replacement steps.

 

Steps to Replace a Chainsaw Chain

Other chainsaw designs may be a little different than that of the chainsaw we use here as an example, but chainsaw designs are similar enough for the steps in this article to help most chainsaw owners regardless of the model they own.

The only tool needed for this repair is the scwrench that most likely came with your chainsaw. Otherwise, a flat head screwdriver and a socket wrench will do just fine.

 

Remove the Old Chainsaw Chain

1. Remove the guide bar side panel.

The side plate on most chainsaws will most likely be held on by two nuts.

Side Panel Nuts 

Using a scwrench or wrench, unscrew the nuts and remove the plate to access the chain.

Side Plate Removed

A chainsaw's brake is sometimes attached to the guide bar side plate, like the chainsaw in our example.

If your chainsaw's brake is attached to its side plate, make sure to unlock the brake before removing sprocket the plate. Removing the side plate with the brake in the locked position can make it difficult or impossible to reinstall.

 

2. Release the chain tension.

The old chain is ready to be removed now that the sprocket plate is off of the saw. Pull the nose of the chainsaw's bar away from the chainsaw to release it from the tensioner.

3. Remove the old chainsaw chain.

The chain will easily remove from the guide bar with all that slack in it.

Steps to Install a New Chainsaw Chain

4. Loosen the tensioning screw. 

Locate the tensioning screw on the inside side of the guide bar and loosen it a little. This will make installing the new chain easier.

5. Thread the new chain onto the saw. 

Carefully thread your new or recently sharpened chainsaw chain around the chainsaw's clutch drum, making sure that the drive links engage in the sprocket.

Thread the rest of the drive links into the guide bar and around its nose.

 

6. Align the guide bar.

With the chain properly threaded along the clutch drum and guide bar, put some tension into it by pulling on the nose of the guide bar away from the chainsaw. 

Pull the Guide Bar

While pulling the guide bar, make sure to seat it onto the saw's adjustment pin.

7. Replace the side plate.

The side plate is ready to go back on as long as the guide bar is properly positioned beneath.

Replace the plate and the nuts that hold it into position, but do not tighten the nuts down all the way yet. The guide bar must be allowed to move a little while the chain is tightened to the correct tension.

 

8. Tighten the chain to the correct tension.

Use the tensioning screw to the side of the guide bar to adjust the tension on the chainsaw chain.

9. Finish tightening the side plate nuts.

The chainsaw chain replacement is now complete.
