Overview
This 2-pack of aftermarket 16-inch replacement chains is designed to fit select Ryobi chainsaw models. It serves as a drop-in replacement when the original chain becomes dull past the point of resharpening, develops a damaged cutter, or has stretched beyond the tensioner’s adjustment range. Having a spare on the shelf eliminates trips to the dealer mid-project.
Key specifications
- Bar length: 16”
- Quantity: 2-pack
- Type: Semi-chisel (aftermarket replacement)
Compatibility
Engineered to match the specifications of select Ryobi chainsaw models, this chain drops in without modification. Before ordering, verify the three critical numbers — pitch, gauge, and drive-link count — against the stamp on your guide bar. A mismatch in any one dimension means the chain won’t fit safely.
Installation notes
Power down the saw and remove the battery or disconnect it from power before servicing. Remove the side cover or bar-cover plate to expose the bar and sprocket. Slide the worn chain off the bar groove and sprocket, noting the direction of the cutters. Install the new chain with cutting teeth facing forward on top of the bar. Reattach the cover and adjust chain tension — the chain should pull slightly away from the bar rail and snap back without sagging.
Common questions
Q: Will this 2-pack S56 replacement chain fit my Ryobi RY40550 16” chainsaw, or is it only for gas models like the RY3716?
Yes, this chain is made to replace an S56-style 16” chain and is listed as compatible with the Ryobi RY40550, RY3716, ZRRY3716, and RY40HPCW02. As long as your saw uses a 16” bar designed for an S56 chain, it should fit properly.
Q: Do I need to do anything special when installing this chain on my Ryobi ZRRY3716?
Make sure the cutters are facing forward on the top side of the bar before tightening the side cover. After installation, adjust the chain tension so the chain lifts slightly from the bar but the drive links still stay engaged, then recheck tension again after the first few minutes of cutting.
Q: How often should I sharpen and oil these 16” chains on a Ryobi RY40HPCW02?
Keep the chain oil reservoir filled every time you use the saw, because a dry chain will wear quickly and cut poorly. Sharpen the chain whenever you notice fine sawdust instead of chips, slower cutting, or if the saw starts pulling to one side.
