I have a Stihl 025, and am very pleased with it.
This past weekend I had the chain to stop turning. I think I shut it down before any real damage occurred. The motor sounds fine and is running quite well. Forgive me if I don't know the correct names of the parts. I removed the chain and bar. The sprocket would turn with difficulty if I used pliers. I removed the sprocket noting carefully where the Jesus clip landed. Inside the "cup" of the sprocket was some pretty tough, sludgy residue that I thought might be the culprit. It cleaned up without much trouble. Then I couldn't get the sprocket back on. A few observations made me want to ask for some advice.
I haven't gone any farther yet. I see inside where the "clutch assembly" is, there is a metal band that forms a ring around the clutch. It doesn't want to come out. I think there might be a tab on the ring holding it in place. I see there is a "break" in the band. It appears to be at a slant. I can't tell as of yet if that "break" is supposed to be there to allow the band to compress or if it's broken. And I don't know if the band goes inside the sprocket cup or outside the cup. I tried both being careful not to force anything and couldn't get the sprocket back on. Do I need to remove the plastic "inner housing" to do that?
A few more questions:
Is the metal band supposed to have a break in it?
Am I barking up the wrong tree? If a tree barks in the forest and nobody hears it, should you cut it down? What if it was a spider on the tree? You have to watch out for barking tree spiders while your sawing logs. They'll get you in your sleep every time.
Should I be concentrating on the clutch assembly?
Are any special tools need to get the sprocket back on?
Thanks in advance,
Tom G.
