Overview

This 2-pack of aftermarket 10-inch replacement chains is designed to fit select Bauer chainsaw models. Over time every chain stretches, dulls, and eventually needs replacing. This aftermarket option matches the OEM pitch, gauge, and drive-link count so you can install it directly without modifications. A fresh chain also reduces strain on the bar and sprocket.

Key specifications

  • Bar length: 10”
  • Pitch: 3/8
  • Gauge: .043”
  • Drive links: 40DL
  • Quantity: 2-pack
  • Type: Semi-chisel (aftermarket replacement)

Compatibility

This chain is manufactured as a direct-fit replacement for select Bauer chainsaws listed in the compatibility section above. Always cross-check the pitch, gauge, and drive-link count stamped on your current bar before ordering — even within the same brand, different models can require different chain specs.

Installation notes

Disconnect power before any chain work. Remove the bar cover to access the sprocket and bar. Take note of the cutter direction, then remove the old chain. Place the new chain in the bar groove with cutters oriented forward on the top rail. Loop it onto the drive sprocket, replace the cover, and turn the tension adjuster until the chain sits snug with minimal sag. Spin the chain by hand to confirm it moves freely.

Common questions

Q: Will this 2-pack chain fit my BAUER 64940 10” cordless chainsaw, or do I need a different size?

Yes, this chain is matched to the BAUER 64940 because it uses the correct 10” setup with 3/8” low-profile pitch, .043” gauge, and 40 drive links. As long as your saw still has the original 10” bar spec, this replacement should fit properly.

Q: How do I know if the tension is correct after installing this 3/8”LP .043 40DL chain?

After installation, the chain should sit snugly on the bar but still pull around by hand with gloves on. If you lift the chain at the middle of the bar, the drive links should start to come out of the groove slightly but not fully jump free, then recheck tension again after the first few cuts since a new chain can stretch a bit.

Q: Can I use this replacement chain on another 10” chainsaw if the bar is also 10 inches long?

Not always, because bar length alone is not enough to confirm fit. The other saw must also use a 3/8” low-profile pitch, .043” gauge, and exactly 40 drive links, so it’s best to verify all three specs on the bar or in the saw’s manual before installing it.

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 (3/8), gauge (.043"), and drive links (40DL) must all match.
  3. Check bar length. Measure cutting length from the tip to where the bar enters the saw body — this should match 10".
  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.
