Overview
This 18” bar and chain combo provides everything needed to restore a chainsaw’s cutting system in one purchase. Running a new chain on a worn bar (or vice versa) accelerates wear on both components. Replacing them together ensures matched tolerances, smooth tracking, and consistent oil distribution from the start.
Key specifications
- 18” guide bar and chain combo
- Matched bar and chain for optimal tracking
- Low-kickback design for safer operation
Compatibility
This combo set is designed for EGO chainsaws as listed above. Verify bar length, pitch, gauge, and drive link count match your saw’s requirements before purchasing.
Installation notes
Remove the side cover and old bar assembly. Clean the mounting area and oil port thoroughly. Mount the new bar, loop the chain around the drive sprocket with the cutters facing the correct direction, and set initial tension. Run the saw for 30 seconds, then re-tension the chain once it warms up.
Common questions
Q: Will this 18 inch replacement bar fit my EGO CS1804, or is it only for the CS1800?
Yes, this bar is made to fit the EGO AK1800, CS1800, CS1803, and CS1804 18” chain saw models. It is also listed for RYOBI RY3818 and CRAFTSMAN CMXGZAM700127 / CMXGZAM700120, so it’s important to match your exact saw model before installing.
Q: Can I use my original chain from my RYOBI RY3818 with this replacement bar?
If your original chain is the correct 18” chain specified for the RY3818 bar setup, it should work with this replacement bar. Before reuse, check that the chain fits the bar groove properly and that the drive links seat correctly on the sprocket and along the bar.
Q: What should I check when installing this bar on a CRAFTSMAN CMXGZAM700120 chain saw?
Make sure the bar slot, chain tensioner hole, and chain direction are all aligned correctly during installation. After mounting, set proper chain tension so the chain lifts slightly from the bar but still snaps back into place, then keep the bar groove and oiling hole clean to help reduce wear.
