- 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.
