Questions people ask

What size chain does an Echo CS-8000P take?

The Echo CS-8000P takes 3/8" pitch, .050" gauge chain. Drive links by bar length: 20" bar 70, 24" bar 81, 27" bar 93, 32" bar 105, 36" bar 116.

How many drive links is an Echo CS-8000P chain?

It depends on the bar: 70 on a 20" bar, 81 on a 24" bar, 93 on a 27" bar, 105 on a 32" bar, 116 on a 36" 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.
