Stihl 090?

[ChuckV309]

I have a huge old Stihl 090. Bought it for $100 about 8 years ago with the 4' bar. The guy selling it said he had not run it for a couple years and could no longer pull it to start it. I stepped on the handle and 3 pulls later it started and ran perfect, so I handed him the $100 and ran. I bought a 2' bar for it because it tips with the 4'. The problem is the clutch/drive sprocket is wearing out. The teeth are worn and the clutch doesn't let the engine idle without spinning the chain. The idle isn't a huge deal for me other than it dies with the 4' bar. Too much drag for idle and restarting all the time is a pain. The saw still has plenty of power; it can still scream with the 4' bar burried in a tree. I've checked with my local dealer and he can't get a sprocket and clutch for it. Any ideas where to get a new one?

wow that is a saw! Watch ebay parts will come in there from time to time

The spring on the clutch is stretched. It's supposed to resist centrifugal force at idle and succumb to it at higher speed.

Chuck, its not worth your time. Send me a pm. I'm only minutes away, I'll take it off your hands and put a couple 100's in your pocket

 

[ChuckV309]

Thanks, Boostnut, but no thanks. I think I'll keep it for now. I've looked on e-bay a couple of times and no luck. I'll keep trying.

Hey boost, where in central IL. I'm thinking of building a custom splitter. maybe we can get together.

Assuming that this part is NLA from your dealer, there are a handful of guys over on arboristsite who should be able to set you up.

I live in washington and work in morton. I work in a fab shop, if you need any help with the splitter let me know. Aaron

Put a "want it now " ad on ebay! I think thats what they call it.

There's no problem getting sprockets for the 070s/090s. I just put a new one on my 090 Lightning a few months ago. I changed it over to 3/8" years ago, from .404 chain and I know, the 3/8" sprockets are easy to get aftermarket.

jdemaris, where did you find/get the sprocket?

Thanks,
Chuck

smart move. I saw a original, like new, 090 sell for $2000 on ebay....your's running is worth close to a grand. They are great saws for chainsaw milling of lumber....check out www.arboristsite.com for good info on milling. bob

Oregon part # RD 108818

Last one I bought was $15. Any Oregon dealer can get it.

 

[ChuckV309]

Besides the chain, is there anything else you have to change to run the different size? Is that $15 for just the sprocket, or does that include the clutch also?

Thanks for the part number.

It's a rim-sprocket kit. For the rim, as I recall, you can get it in 3/8" or .404 - I just happen to prefer the 3/8"

With a rim-sprocket - you can change chain pitch without changing the whole one piece drum and sprocket which is kind of a plus.
