Overview

Built for STIHL 71PM3-64 chainsaws, this replacement chain delivers consistent cuts and reliable durability at a fraction of OEM cost. Keeping a spare chain on hand means less downtime during jobs, and swapping a dull chain takes just minutes.

Key specifications

  • Bar length: 12”

Compatibility

This replacement chain works with STIHL 71PM3-64. Always confirm your saw’s model number and bar length before ordering to ensure proper fit.

Installation notes

Power down the saw and disconnect the battery or spark plug lead. Remove the side cover and release bar tension. Take the old chain off the bar and sprocket, then thread the new chain into the bar groove, confirming the cutting edges face forward on the top rail. Set the tension so the chain pulls freely without sagging away from the bar, and do a brief test run to verify everything tracks correctly.

Common questions

Q: Will this 12 inch chainsaw chain fit my saw if it currently uses a STIHL 71PM3-64 chain?

Yes. This chain is made to replace the STIHL 71PM3-64 spec, so it matches a 12 inch setup that uses that exact chain designation. The most important thing is that your saw and bar are set up for a 64 drive link chain in the 71PM3 series.

Q: I have a 12 inch bar, but how do I confirm this chain is the right one before installing it?

Check the markings on your current chain or bar and verify that it calls for STIHL 71PM3-64. Matching the chain family and drive link count is more reliable than bar length alone, because two 12 inch bars can use different chain sizes. If those markings match, this chain should install and tension normally.

Q: Any tips for installing and maintaining this 12 inch replacement chain on my saw?

Make sure the cutters face forward on the top side of the bar when you install it, then set the tension so the chain sits snugly but can still be pulled around by hand with gloves on. After the first few cuts, recheck tension since a new chain can stretch slightly. Keep the bar oil reservoir full and touch up the cutters regularly to help the chain cut straight and reduce wear.

Compatibility

This part is verified to fit the following equipment. Always confirm the model number stamped on your machine before ordering.

Not sure which chain you need? See our guide: How to count drive links or Chain pitch, gauge & drive links explained.

Before you buy — how to verify fitment

  1. Find the bar stamp. Look on the side of your current guide bar for the pitch, gauge, and drive-link count.
  2. Match all three numbers. Pitch (1/4), gauge (.043"), and drive links (64DL) must all match.
  3. Check bar length. Measure cutting length from the tip to where the bar enters the saw body — this should match 12".
  4. Confirm your saw model against the compatibility list above. If your model isn't listed, the chain may still fit if pitch/gauge/DL match.

Frequently asked questions

How do I know this chain fits my saw?

Match three numbers: pitch, gauge, and drive-link count. All three must match the stamp on your current bar. If even one is off, the chain won't fit safely.

How do I measure pitch and gauge?

Pitch is the distance between any three consecutive rivets, divided by two. Gauge is the thickness of the drive links — measure with a caliper or check the bar stamp. Our guide covers both in detail.

How long does a replacement chain last?

With proper tension and occasional sharpening, an aftermarket chain lasts 3–5 cords of firewood or about 5 hours of active cutting — roughly the same as OEM.

Can I sharpen this chain or is it single-use?

Absolutely sharpen it. A quality replacement chain can be sharpened 3–5 times before the cutters are too short. Keep a round file matched to the cutter diameter.
