Overview
This aftermarket 20-inch replacement chain is designed to fit select Craftsman chainsaw models. When the factory chain wears out, loses its edge after multiple sharpenings, or stretches past the tensioner’s range, this chain gets you back to cutting without waiting for a dealer order. It’s built to OEM dimensions for a direct fit.
Key specifications
- Bar length: 20”
- Type: Semi-chisel (aftermarket replacement)
Compatibility
This chain is manufactured as a direct-fit replacement for select Craftsman 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
Before swapping the chain, set the saw on a stable surface and let the engine cool if gas-powered — or remove the battery on cordless models. Loosen the bar nuts, slide the bar forward to slacken the old chain, and lift it off the sprocket and bar nose. When seating the new 20-inch chain, make sure the cutters point forward along the top edge of the bar. Snug the bar nuts, then adjust the tensioning screw until the chain pulls away from the bar about 1/8 inch and snaps back cleanly.
Common questions
Q: Will this 20” replacement saw chain fit my CRAFTSMAN CMXGSAMY462S S205 46cc chainsaw with the factory 20-inch bar?
Yes, this chain is intended for the CRAFTSMAN CMXGSAMY462S S205 using the stock 20-inch bar. If your saw still has the original bar setup, this is the correct replacement length; if the bar has been changed to a different size, match the new bar length and chain specs before installing.
Q: Do I need any special steps to install this chain on the CRAFTSMAN S205, or is it a standard chain swap?
It installs like a standard chain replacement: loosen the side cover, back off the chain tensioner, fit the chain around the clutch drum and bar, then reinstall and tension it correctly. Make sure the cutter edges on the top of the bar face forward, and recheck chain tension after the first few minutes of cutting since a new chain will usually stretch slightly.
Q: How should I maintain this 20-inch chain on my CMXGSAMY462S so it cuts properly and lasts longer?
Keep the chain properly tensioned, use clean bar-and-chain oil, and make sure the bar oiling hole and groove stay free of sawdust buildup. Touch up the cutters regularly instead of waiting until the chain is very dull, and inspect the drive links and depth gauges for wear each time you clean the saw.
