Early year MS360.
While diagnosing some clutch and oil leak issues, I found this formed wire that wraps around the oil pump drive gear had broken and destroyed the oil delivery line. The "finger" had broken off. The saw had been oiling fine but leaking a ton of bar oil. I found it was a bad oil pump gasket.
I ordered the gasket, oil hose assembly, oil pump, and a new new drive gear assembly, hoping the purpose of the wire would be apparent, but that is not the case. What is this wire for? Am I missing a part in the case (or has been destroyed also) that it should catch on?
Wire is circled in the 4th photo.
