Overview

Sold as a 2-pack, this chain is a direct replacement for RYOBI RY40HPCW03K models. Running a dull chain forces the motor to work harder and shortens the life of your bar, making periodic replacement essential.

Key specifications

  • Bar length: 20”
  • Pitch: 3/8”
  • Gauge: .050”
  • Drive links: 70 drive links
  • Quantity: 2 chains per pack

Compatibility

This replacement chain works with RYOBI RY40HPCW03K. Double-check your model number against the listing to ensure a correct match before installation.

Installation notes

Disconnect the spark plug wire or remove the battery before changing a chainsaw chain. Remove the bar cover, release bar tension, and take off the old chain. Place the new chain into the bar groove with the cutting teeth facing forward on top. Reinstall the cover, adjust chain tension until snug, and test by pulling the chain around the bar by hand. Re-check tension after a few minutes of use.

Common questions

Q: Will this 2-pack 20-inch chain fit my RYOBI RY40HPCW03K, and does the 3/8 pitch match the original setup?

Yes, this chain is made for the RYOBI RY40HPCW03K and matches the 20-inch bar length with a 3/8 pitch. As long as your saw is still using the stock 20-inch bar, it should fit properly and run as intended.

Q: Do I need to do anything special when installing one of these chains on my RY40HPCW03K?

When installing, make sure the cutting teeth on the top of the bar are facing forward and then set the chain tension so it sits snugly against the bar but still pulls around by hand. After a short test run, recheck the tension because a new chain can stretch slightly during initial use.

Q: How should I maintain these 20-inch saw chains to keep them cutting well on my RYOBI?

Keep the chain properly tensioned, make sure the bar oil system is working, and clean sawdust out of the bar groove and drive area regularly. If cutting starts to feel slow or the saw throws fine dust instead of chips, it is usually time to sharpen the chain or inspect it for 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 (3/8), gauge (.050"), and drive links (70DL) must all match.
  3. Check bar length. Measure cutting length from the tip to where the bar enters the saw body — this should match 20".
  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.
