How are these roller bearing installations handling thrust loads ...if there are any. Do any have this installed? I hope oil film is not being relied upon.

Personally, I would not be at all on board with putting a groove down the length of my oil pump hex drive. A centre hole may work if you are a gambling man. That section looks too small to begin with an now one has introduced notch sensitivity that is off the scale for torsion.....imho
