So are there like just 3 sprocket (rim) manufacturers with low tolerance? I have seen a fair amount of this from Oregon. I have heard about issues with Stihl sprockets, now I see them myself. I got 2 new Stihl sprockets from different locations at different times. Both look like the off Oregon ones I have seen and had. At first glance it won’t seem like anything, but I have ran sprockets like this and you get the chain tension that changes as the chain rotates. In one place it’s tight, move it 8” and it gets more loose. Last night I ordered oregon rim sprockets from 2 different places. I have seen some for sale made in USA and Switzerland, pics of the USA made ones seemed to have the same issues. This almost makes me make an adapter and have them machined…do you just have to order them in bulk and pick out the good ones. This is nuts! Is there anyone else who is particular and found a solution/supplier?
In the pics, the first one the pins are flat and flush, 2 are flat. As you rotate they get lower and get rounded. It doesn’t look like much but it’s enough to be annoying when you don’t like to run a too tight chain.
