Hi,
I have disassembled the entire powerhead (engine) for complite overhaul. I am going to replace all the worn parts and of course all the seals. Question about crankshaft bearings. There's a small pin on outer race of the bearing and it's unclear does the new bearing need to have that pin as well? Many sources on internet offers Koyo 6204c3 bearing as replacement for original Yamaha spare, but it does not have this pin.
