That’s what I do. Usually that’s right about when the wear indicator on the Oregon sprockets is worn off too. The OP’s picture of that particular sprocket? I toss them when they look like that. It’s one of those parts that’s so cheap to replace that it isn’t worth getting every last bit of performance. I found I get longer life out of sprockets keeping proper chain tension and cranking the oiler up as much as possible. I wore out 3 bars and a lot of chains with the original sprocket on my 572.
EBay em bro. I buy em in tens for less than $10 NZD ea landed. Holla if you want the vendor details.
Cheers but I'm right I no longer work in the timber industry am no longer a slave to it so I actually have free time to look around for better deals now days life is good.
Your MS261 uses a Stihl proprietary 'micro spline™'. Some refer to them as mini-spline. This spline size is smaller than your regular small spline Oregon/whatever brand sprocket. Now you can change your clutch drum out to an Oregon to run standard small spline rims or you can now buy micro spline rims on eBay from China in .325 or 3/8 Picco for about $3 a pop. If you run Oregon small spline they will work and you can cut wood but you'll round off the edges on the drum splines in short order, wrecking the drum. I've been pretty happy with the AM rims from China, I ain't paying $33 at the Stihl dealer.
