RYOBI P2570 / P2507BTL 12 Replacement Chain, 64 drive links

Fitment overview

This replacement chain is made for select 12-inch RYOBI chainsaws, specifically the RYOBI P2570 and P2507BTL as listed for this product page. It is a 12-inch chain with 1/4″ pitch, .043″ gauge, and 64 drive links, so matching those specs exactly is the key to proper fit.

You will receive 2 pieces in the package, which is helpful if you want a spare chain ready to go when the first one needs sharpening or replacement.

Will this chain fit your saw?

This chain is intended for a 12-inch bar and uses these exact chain parameters:

• 12-inch bar
• 1/4″ pitch
• .043″ gauge
• 64 drive links

Compatible saw models listed for this product:

• RYOBI P2570
• RYOBI P2507BTL

There is one important fitment note from the original listing: this chain is only suitable for RYOBI P2570 model chainsaws, and other models are not compatible. Because the title also references P2507BTL, the safest approach is to verify your exact saw model and confirm the chain specs on your current bar or chain before ordering.

To check fitment, look at four things:

• Saw model number: Confirm your tool is marked RYOBI P2570 or P2507BTL.
• Bar length: Your saw should be using a 12-inch bar.
• Pitch: This chain is 1/4″ pitch.
• Gauge: This chain is .043″ gauge.
• Drive-link count: Your replacement must have 64 drive links.

If even one of those measurements is different, the chain may not fit correctly or operate safely. A chain that is too long, too short, too thick, or too thin for the guide bar can cause poor cutting performance, tensioning issues, or premature wear.

If your current chain is still available, one of the easiest ways to confirm fit is to compare the markings and count the drive links on the old chain. You can also check the guide bar stamp if your bar lists pitch and gauge.

Replacing the chain

Always remove the battery or make sure the saw cannot start before doing any chain service.

1. Power down the saw fully. Remove the battery and set the chainsaw on a stable surface.
2. Open the side cover. Loosen the bar/cover hardware according to your saw’s design and remove the side cover.
3. Remove the old chain. Lift the chain off the drive sprocket and guide bar, then remove the bar if needed to clear debris from the bar groove and sprocket area.
4. Install the new chain. Place the chain around the drive sprocket and along the bar groove, making sure the cutting edges face the correct direction on the top of the bar.
5. Set chain tension. Reinstall the side cover and adjust tension so the chain sits snugly in the bar groove but can still be pulled around by hand with gloves.
6. Recheck before cutting. Tighten everything securely, then check tension again after a short test run, since a new chain can settle in quickly.

If you are unsure about chain direction, stop and double-check before running the saw. Installing a chain backward is a common mistake and will prevent proper cutting.

Keeping it sharp

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

• Avoid dirt and ground contact. Even a brief touch in soil can dull a chain quickly.
• Check chain tension often. A loose chain can wear faster and cut poorly; a chain that is too tight can overheat and stress the bar and drive system.
• Touch up the cutters early. Light, regular sharpening is usually easier and better for chain life than waiting until the chain becomes very dull.

Also keep the bar groove and oiling path clean so the chain runs smoothly.

FAQ

Does this fit any 12-inch RYOBI chainsaw?

No. A 12-inch bar alone is not enough to confirm fit. Your saw should match the listed model and chain specs: 1/4″ pitch, .043″ gauge, and 64 drive links.

How many chains are included?

The package includes 2 pieces of 12-inch replacement chain.

What should I do if my old chain has different specs?

Do not use this chain unless your original setup matches the listed specifications exactly. Confirm the saw model, bar length, pitch, gauge, and drive-link count before installing a replacement.
