Stihl 011 3/8 Picco 7 tooth sprocket NLA?

[dwaugh]

Not sure if I should start a new thread, but I had one on a piston stop for the 011 (consensus was the metal one I had was not good to use, so go for rope or impact), I got the clutch off to lubricate the bearing, but figured I might as well replace the bearing and the spur sprocket. The local dealer had to order the bearing, but the 7 tooth spur sprocket 1120 640 2005 seems to be no longer available (NLA). The dealer is going to explore that further. Not sure if the 6 tooth sprocket is NLA, but I have seen more of those online both Stihl or aftermarket. The wear on my current sprocket is not bad and the saw sees low use currently so this is hardly a priority. I guess I'm wondering if anyone familiar with these saws knows of a drop in replacement, or if I could run the 6 tooth sprocket without needing to shorten the chains I have. Thanks.

Can't see the worn area on the spurs.

Ebay has aftermarket 7T rim style $26 shipped.

Yeah, the wear is not to bad. (Photo below) I just figured if it was in stock/available at the dealer and I had the clutch off I would replace it and keep the old one in reserve. If the dealer doesn't find something I will go the eBay route like you suggest.

It's getting there. Would be good to have a new sprocket next time you replace chain.

The last one I got for my 011AV on eBay in 2022 was made in the USA by Oregon... It was exactly the same as my Stihl sprocket...
Note, I was running a 6T sprocket, not a 7T.

If you search on eBay for "NOS Oregon 28016 Spur Sprocket for Stihl 009, 010, 011, 020", you will get plenty of hits for 6T sprockets.
I don't know if Oregon made a 7T version. Someone else here probably does...
I have no experience with other aftermarket versions.

Heard back from the Stihl dealer it is really NLA so I will go that (eBay) route you suggested.
I ordered this rim sprocket kit, hope it fits, not sure if this is the one you saw https://www.ebay.com/itm/3849839427...T8WeHWQ4SlYrV5RCRT4jrwIJE=|tkp:Bk9SR6y7--X8ZA

I see the second picture in the rim drive kit shows 3/8lp but the first picture seems to just show a 3/8 sprocket. Kind of curious if it is a mini spline or generic small spline kit.

rsm 375 7 rim sprocket I searched this and it seems not technically for 3/8lp but will work ok in the saw size you have.

I assume you are talking about the kit I linked to (that I just ordered)? Yeah, I'm not convinced it will work. I'm running 3/8lp now but I wonder if the sprocket is really 0.375... Guess I will find out
