Questions people ask

What size chain does a Stihl MS 881 take?

The Stihl MS 881 chain depends on the bar. 21" bar: 3/8", .063", 75 drive links; 25" bar: .404", .063", 80 drive links; 30" bar: .404", .063", 91 drive links; 36" bar: .404", .063", 104 drive links; 36" bar: .404", .063", 108 drive links; 41" bar: .404", .063", 123 drive links.

How many drive links is a Stihl MS 881 chain?

It depends on the bar: 75 on a 21" bar, 80 on a 25" bar, 91 on a 30" bar, 104 on a 36" bar, 108 on a 36" bar, 123 on a 41" bar. The bar length is usually printed near the mount.

Can I use a chain with the same length but different pitch?

No. Pitch and gauge have to match the bar and sprocket, and the drive link count has to match the bar. A chain that is off on any of the three will not fit or run safely.
