Stihl 201 tcm problem- chain making contact with body

[hohriver]

As the picture shows, it appears the teeth of my chain are coming into contact with the plastic body behind the clutch. Initially, thought my clutch was going bad.
Any help trouble shooting before I have to take it to a shop would be appreciated.

Recently replaced the bar and chain, wondering if it’s not mismatched equipment failure.

That clutch drum rides on a needle bearing. From the photo your clutch drum may be tilted. Only thing that would allow this is bad needle bearing. Other than that, something has to be out of place. The sprocket, bar, and chain all have to match.

I have seen MS500I's ran with a bad drum bearing until they ruined a $1400 saw.

This usually happens when a ms201t throws a chain.

Looks like damage from a thrown chain, which is enhanced by a lose chain......or little limbs

All the above actually.

Looks like the chain was thrown off. If the clutch assembly is tight and don't rock a lot when you try to move it, then that means it's just from a chain being derailed! You would hear all that carnage if it was hitting, and you would know something was wrong instantly.

..... If you bothered to listen that is....

Thanks for everyone’s time responding. Helped me to realize plastic damage wasn’t part of the problem. Wish could say never thrown a chain, which is just as embarrassing as a misfire.

Don't let the chain hang off the bar, it should be ever so lightly tight.
