Stihl 041av clutch

[gergis]

Hello,
My old 041 chain stopped spinning. I’d like to get her back in service…she runs awesome and is my spare for when my 290 touches rocks or throws a chain and I’m wanting to get finished.
A few questions:
Regarding the gap between weights and inner drum, does it look excessive? There’s obviously a limit….does this look like it?
Is there still OEM clutch parts available for this old girl?
Looks like a special tool is required?
I’m aware that it has a left-hand thread.
Thanks in advance

Yes, tool required but they are easy to make if you have a welder.

That looks like an isolating clutch. Cool stuff. I used a grinder tool thingie on my 031.

Grinder tool….now why didn’t I think of that?

Thanks!

That gap looks pretty big to me- you probably had the old friction shoe clutch and the shoes have worn away or disintegrated. The all steel clutches are the way to go when replacing them.

Hoping the steel clutches are still in production/available? Thanks!

They should be, if not they are pretty easy to find used. iirc they are the same one as on a 031

Pretty sure 031,032 and 041 interchange sprocket and clutch.
If anyone needs 1 , I and probably dozens of others here got some good used ones in our parts stashes somewhere .

They sure look the same. I know the springs are still available for the 031 isolating clutch.

The isolating ones? Those are rare in Europe. Were they so common in the US? I saw two isolating clutches with the covers go for 95€ on evilbay.

I have seen the isolating version now and then over a few decades. Not sure if i have 1 in that version or not currently.

Here is the regular clutch.

Here is what they show for the 031, in case you might come across one of thoses.

I do . So I didn't pay the 90€.
The 030/031/032 all sound great in my ears.

Couldn’t find much info on what an “isolating” part of the clutch is/does.
Anyone care to school me?

When activated, the clutch gets disconnected from the crankshaft. So the engine can spin freely with engaged brake.

Well isn’t that slick. I was just messing around with it and indeed it does release the clutch from the crank. Now….could a misbehaving part of the isolator be causing the clutch to freewheel?
