i guessed crank bearing

another guess was the plating let go shifting the ring and the ring popped through the crown at the locator pin.

what do you think?

thank you
that gray stuff is from aluminum, it is what you get when you try to polish aluminum,  there was a lot of it.
if you look on the piston  you can still see the machine marks,  fairly low hours.

Are you sure the rod big end bearing on the crank did not fail? Grab the rod and check for up-down play at the big end of the rod. If any noticeable play, and you are looking at a new crank, OEM only, none of that Chinese stuff!

Usually when a crankcase main bearing fails the counter weights will contact the case, rubbing it raw, check for that also. Use bright light and dentist's mirror.

Seen the big end go out on a good bit here. Check her out David.   I only used new oem kits or used good. 
Some folks say they have had good luck with some of the aftermarket ones, but I was scared to do it for a saw I would evidently sell down the road. If I had kept them I might have tried one.
