Overview
This aftermarket 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
- Type: Semi-chisel (aftermarket replacement)
Compatibility
This chain is designed as a direct replacement for select Craftsman chainsaws. Double-check the pitch, gauge, and drive-link count on your existing bar stamp before purchasing. These three measurements must all match for safe operation.
Installation notes
Start by removing the battery or disconnecting the power cord. Take off the bar-cover plate and release bar tension. Pull the old chain out of the groove and off the sprocket. Seat the replacement chain into the bar groove — cutters must face forward on the top of the bar. Engage the chain on the drive sprocket, reinstall the cover, and adjust tension so the chain lifts about a dime’s width off the bar and springs back. Hand-rotate the chain to check for binding before powering on.
Common questions
Q: Will this 18-in chainsaw chain fit my CRAFTSMAN S1800 model CMXGSAMCX4218, or is it only for the S180?
Yes, this chain is made for the CRAFTSMAN S180, S1800, and S185 42-cc 2-cycle 18-in gas chainsaws, including model CMXGSAMCX4218. It is also listed to fit model #CMXGSAMY42N8 and CMXGSAMY421S, so if your saw matches one of those model numbers, this is the correct replacement chain.
Q: Do I need any special tools to install this replacement chain on my CRAFTSMAN S185 18-in saw?
You typically just need the scrench or bar-nut tool that came with your saw to loosen the side cover, remove the old chain, and tension the new one. Make sure the cutting teeth face forward on the top of the bar, then adjust the chain so it sits snugly against the bar but still pulls around by hand with gloves on.
Q: How often should I sharpen and tension this chain on my CRAFTSMAN 42-cc 18-in chainsaw?
Check chain tension every time you refuel, especially during the first few cuts with a new chain, because new chains can stretch slightly as they break in. Sharpen it whenever you notice fine sawdust instead of wood chips or if the saw starts pulling to one side, and always keep the bar oil reservoir filled to reduce wear on the chain and bar.
