Questions people ask

What size chain does a Stihl MSA 220 TC-O take?

The Stihl MSA 220 TC-O takes 3/8" pitch, .050" gauge chain. Drive links by bar length: 12" bar 44, 14" bar 50, 16" bar 55.

How many drive links is a Stihl MSA 220 TC-O chain?

It depends on the bar: 44 on a 12" bar, 50 on a 14" bar, 55 on a 16" 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.
