Opuladuo 2PC 12 Inch Chainsaw Chain for Stihl 71PM3 64/71 PM3 64

If you need a replacement chain for a saw that uses the Stihl 71PM3-64 / 71PM3 64 spec, this Opuladuo 2PC 12 Inch Chainsaw Chain is designed around that fitment. It is a 12-inch replacement option and the package includes 2 pcs 12-inch chain, which is useful if you like to keep a spare ready for quick swaps.

Will this chain fit your saw?

The most important thing is matching the chain to your bar and saw setup, not just matching the bar length alone. A 12-inch bar is the starting point, but you should also confirm the chain’s pitch, gauge, and drive-link count against the markings on your current bar, current chain, or your saw’s manual.

This product is listed as replacing these Stihl chain part numbers:

• Stihl 71PM3-64
• Stihl 71PM3 64
• 3670-005-0064
• 3670 005 0064

To confirm fitment, check these points:

• Bar length: your saw should use a 12-inch bar
• Chain family / part number: your current chain or manual should reference 71PM3-64 / 71PM3 64 or 3670-005-0064 / 3670 005 0064
• Pitch, gauge, and drive-link count: these must match your current setup exactly

If your existing chain has one of the replacement part numbers above, this is the most reliable sign that the chain is a correct match. If your saw has a 12-inch bar but uses a different chain number, do not assume it will fit. Two 12-inch setups can still use different chain dimensions.

A quick visual check helps too: compare the old chain packaging, the stamp on the guide bar, or the parts information in the owner’s manual. If those references match the numbers above, you’re on the right product page.

Replacing the chain

Changing a chainsaw chain is straightforward, but safety comes first.

1. Turn the saw off completely and disconnect the power source or make sure the engine cannot start accidentally. Wear gloves before handling the chain.
2. Loosen and remove the side cover so the bar and old chain can be taken off. Release chain tension first if needed.
3. Lift the old chain off the sprocket and bar, then clean out sawdust and debris around the bar groove, sprocket area, and tensioner.
4. Install the new 12-inch chain onto the bar and around the drive sprocket, making sure the cutter direction is correct.
5. Refit the side cover and apply tension until the chain sits snugly in the bar groove but can still be pulled around by hand with a gloved hand.
6. Tighten the bar nuts securely, then recheck chain tension after a short test run since a new chain may settle in.

If you are replacing a heavily worn chain, it’s also a good time to inspect the guide bar for uneven wear and make sure the sprocket area turns smoothly.

Keeping it sharp

A sharp chain cuts faster, puts less strain on the saw, and is safer to use than a dull one.

• Keep the chain properly tensioned. A chain that is too loose can jump the bar, while one that is too tight creates excess heat and wear.
• Maintain good lubrication. Always make sure bar-and-chain oil is flowing correctly so the chain and bar stay protected during cutting.
• Touch up the cutters regularly instead of waiting until the chain is very dull. If the saw starts producing fine dust instead of chips, or you need to force the cut, it’s time for maintenance.

Also avoid cutting into dirt, rocks, or fence wire. Even brief contact can dull a chain very quickly.

FAQ

Does this include one chain or two?
This package includes 2 pcs 12-inch chain.

Is matching the 12-inch bar length enough to confirm fit?
No. Bar length is only one part of fitment. You should also match the chain part number and confirm pitch, gauge, and drive-link count with your current chain, guide bar, or owner’s manual. If your setup matches Stihl 71PM3-64 / 71PM3 64 or 3670-005-0064 / 3670 005 0064, this is the correct replacement style to check for.
