Stihl MS 170 Chain Questions
What size chain does a Stihl MS 170 take?
3/8" LP (Picco) pitch, .043" (1.1mm) gauge, on every MS 170. Drive link count depends on your bar: 44 DL for the 12", 50 DL for the 14", 55 DL for the 16".
How many drive links is an MS 170 chain?
Count depends on bar length — see the table above. If you're unsure which bar you have, the DL count is usually stamped on the bar itself, or count the drive links on your old chain.
What file do I use on an MS 170 chain?
A 4.0mm round file suits this 3/8" LP chain.
Will this chain fit other Stihl saws?
Possibly, but please use our Search by Chainsaw tool to find your specific saw chain with no doubt.
Is this a genuine Stihl chain?
No — it's an Alpine Chain Co. chain manufactured to fit the MS 170, replacing the Stihl 61PM3 and Oregon 90PX. Same pitch, gauge and drive link options, with a semi-chisel profile chosen for Australian hardwood. Every fit is backed by our Guaranteed Fit system.
How to Verify Your Chain Size
If you are unsure if this is the correct chain for your Stihl MS 170, check the side of your current guide bar. The Pitch, Gauge, and Drive Link (DL) count are typically stamped directly into the bar near the mounting bolts.
