Clutch Overheated. Still OK?

[Clarkbug]

So a while ago I got a free Echo CS-310, and have enjoyed the project of getting it going again. The whole thing was filthy, and I think it was not well loved.

I got a new sprocket since the old one was worn, and figured I would pull the clutch while I was in there and clean it up. I put it in the ultrasonic cleaner and this is what came out.... Didn't expect it to be that shade of purple. Clearly got a little hot in the past.

What does it mean when they get this hot as far as future use? Can I still run it? Better to swap it for a new one? Sorry if it's a dumb question.

It's not hardened steel like a knife or axe is, so it's not like your gonna ruin the temper.
Prolly fine I'd think (could be wrong).

Make sure to grease clutch drum bearing before reassembling.

The springs could get impacted by the heat, right?

Is it a good idea to use any oil or never seize on the clutch threads? Or is that asking for trouble down the road?

Thanks for the reminder on the bearing.

I think your overthinking it.
Just rough up the clutch shoes some (lightly sand) if they are glazed, clean the clutch drum (make sure there are no grooves) & grease the drum bearing (any grease will work).

No need for anything on clutch threads, just clean em.

The springs should be ok. If it idles without spinning the chain or dragging, the springs should be ok. If they lost temper, they will stretch out and be soft.

I'd bet MOST clutches would have that color out of ultrasonic cleaner. Lol
That 310 is a little beast (especially with a mod or two).
Featherweight saw.

Clutches shouldn't really get hot under normal use. Mine still look the same as when they were put in. As long as you are letting the saw hold rpm in the wood, the clutch should stay locked up tight. The only time the clutch should ever slip is when it first engages, just like a truck.

Oh I'm for sure overthinking it.. That's why I posted here to get set straight. Or at least overthink it a little less.

I really like this little thing after gutting the cat in the muffler. It's nice and light and sips fuel. Nice for limbing stuff or cutting brush. I wouldn't have bought one, but as a free saw it's a good time.

Thanks for the advice gents!
