Mine is definitely the drum(or crankshaft), I had oem bearings too. Got an Oregon drum otw, hopefully it's the drum and not the crankshaft bc I have the saw mostly togetherI had other bearings that I used instead. If check your Stihl dealee for one. My second one fit, just tight.
I put the drum on first and its a little easier to slide the bearing into the drum.
