Bought a blown up 357xp. Looked like crank bearing went when I bought it based off of looking at top of piston. Got new bearings on way home. Got it home took seals off to inspect bearings and all is good , what the hey! Bearings good, no slack, rotate freely except some loose metal or something at bottom of case the crank catches on. Cylinder walls are nice with slight transfer and a banged up roof and a broken muffler bolt hole. I looked everything over to find out where the metal came from(Bearings/cages/stuffers/crank and couldn’t find anything. I do not recall the ring being damaged when I pulled it off either. Maybe muffler gasket? It was in pieces in a bag that came with the saw. Any ideas when caused this ? I included a few good pictures. It’s an early model with 13mm piston rod end. It’s narrower on top then bottom, that normal?
