Overview
Designed as a drop-in aftermarket replacement, this 14” bar and chain combo takes the guesswork out of ordering parts separately. The bar rail and chain pitch are matched at the factory, so everything lines up the first time you mount it. A practical upgrade for homeowners maintaining their own firewood saws.
Key specifications
- Bar length: 14”

Compatibility
This combo is built to work with Stihl MS 170 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
Loosen the bar-mount nuts and slide the old assembly off. Before fitting the new bar, clear packed sawdust from the oil passage and around the drive sprocket. Place the new bar onto the studs, route the chain around the bar groove and sprocket, then adjust tension to the point where you can pull the chain around by hand with light resistance. Snug the nuts in a cross pattern.
Common questions
Q: Will this 14-inch bar and chain combo fit my Stihl MS 170 without any modifications?
Yes, this combo is intended for the Stihl MS 170 and matches the 14-inch bar length with a 3/8 pitch setup. As long as your saw is using the standard MS 170 bar mount and sprocket, it should install normally with no modification needed.
Q: How do I properly tension the chain after installing this 14-inch bar and chain on my MS 170?
After mounting the bar and chain, adjust the tension so the chain sits snug against the bar but can still be pulled around by hand while wearing gloves. Recheck tension after the first several cuts, because a new chain on a Stihl MS 170 will usually stretch slightly as it seats in.
Q: Is a 3/8 pitch chain correct for a 14-inch guide bar on the Stihl MS 170, and what maintenance should I do to keep it cutting well?
Yes, this combo uses a 3/8 pitch chain, which is the correct pitch specification for this setup on the MS 170. Keep the chain sharpened, maintain proper bar oil flow, and clean the bar groove and oil holes regularly to help the bar and chain wear evenly.
