I have an Echo CS-370 saw that I bought used, and I've read what seems to be a variety of opinions on when to replace the drive sprocket. It seems that the manufacturer websites say after you wear out 2-3 chains, the sprocket should be replaced. I have also read that ~0.5mm wear on a sprocket is the acceptable limit.
Some other things I have read from user forums seem to indicate that the recommendations above are overkill.
I have bought a new chain for the saw, as the one that is on it was pretty worn (it was not the original chain). I am also planning to replace the bar. Below are a few pictures of the sprocket. If you were in my shoes, would you replace it? Thanks...
