Overview
A replacement chain engineered to match the original specifications of CRAFTSMAN S1800 / S185 chainsaws. Comes in a convenient 2-pack, giving you a ready spare. Running a dull chain forces the motor to work harder and shortens the life of your bar, making periodic replacement essential.
Key specifications
- Bar length: 18”
- Quantity: 2 chains per pack
Compatibility
This chain is designed to fit CRAFTSMAN S1800 / S185. Double-check your model number against the listing to ensure a correct match before installation.
Installation notes
Power down the saw and disconnect the battery or spark plug lead. Remove the side cover and release bar tension. Take the old chain off the bar and sprocket, then thread the new chain into the bar groove, confirming the cutting edges face forward on the top rail. Set the tension so the chain pulls freely without sagging away from the bar, and do a brief test run to verify everything tracks correctly.
Common questions
Q: Will this 2-pack 18-inch chain fit my CRAFTSMAN S1800, or is it only for the S185?
Yes, this chain set is made to fit both the CRAFTSMAN S1800 and S185 when they are using the 18-inch bar. If your saw still has the original 18-inch setup, these replacement chains should match correctly.
Q: Do I need to do anything special when installing one of these chains on my CRAFTSMAN S185?
Make sure the saw is unplugged before installation, then confirm the cutting teeth are facing forward on the top side of the bar. After mounting, set the chain tension so it sits snugly against the bar but can still be pulled around by hand, and recheck tension after the first few minutes of use.
Q: How often should I sharpen or replace these 18-inch chains on my CRAFTSMAN S1800?
That depends on what you cut, but if the saw starts making fine dust instead of chips, pulls to one side, or needs extra pressure, the chain likely needs sharpening. Replace the chain if the cutters are heavily worn, damaged, or if repeated sharpening no longer restores good cutting performance.
