- Chain pitch: .325”
- Includes: guide bar and chain (matched set)
- Material: hardened alloy bar with chrome-plated chain
Compatibility
This combo is built to work with Stihl MS230 and equivalent models that share the same bar-mount geometry. Confirm your saw’s model and year against the compatibility chart to ensure a proper fit, particularly if your saw has been updated with a different oiler setup.
Installation notes
Remove the side cover, slide the old bar off the studs, and clean any sawdust from the bar-mount area and oil port. Seat the new bar on the studs, loop the chain around the sprocket and bar nose, then hand-tighten the cover nuts. Adjust chain tension until the chain pulls away from the bar bottom about 1/8 inch and snaps back, then torque the nuts securely.
Common questions
Q: Will this 18 inch bar and .325 pitch chain combo fit my Stihl MS230 without any modification?
Yes, this combo is made to be compatible with the Stihl MS230, so it should mount correctly as long as your saw is set up for an 18 inch bar and a .325 pitch chain. It’s still a good idea to confirm your current setup matches the 18 inch length and .325 pitch before installing, especially if your saw was previously running a different bar and chain size.
Q: Do I need to do anything special when installing this guide bar and chain on my MS230?
When installing it, make sure the chain is facing the correct cutting direction on the top of the bar and that the tension is snug but still allows the chain to move freely by hand. After a few minutes of cutting, recheck chain tension because a new chain will usually stretch slightly during initial use.
Q: How should I maintain this 18 inch chain and guide bar to make it last longer on my Stihl MS230?
Keep the chain properly sharpened, maintain correct tension, and always make sure bar oil is flowing before cutting. It also helps to clean the bar groove and oil holes regularly, and flip the guide bar periodically so wear stays even from one side to the other.
