Thanks so much for helping me out with this.
I’ve posted pictures, I think I have the notch in the front crankcase half that you are talking about. So I’ll NOT install the o-ring on the top.
If I could follow up with a related question on these crank bearings – On the back half there are small tubes that I’ll assume are for injecting oil into the bearings… do I line the holes in the bearings up with the tubes or do the tubes just fit anywhere in the slots on the bearings?
