Right...but you flipped the bevel gear orientation from the pic to your #3!
In your #3, lower the bevel gear so it's closer to the C/L of the blue line than in your #1. No matter how deep/shallow you set the motor height, you can't get sufficient tooth to tooth contact. I suspect that's what was happening with my gear set, it was set to "low" (ref. your homemade pics) and needed to be raised.
True, at any rate with the caged set I have no idea what do do with them, except put them in the spare parts bin. I was told that you can dismantel that cage and use the gears are loose individual gears.
