In my case, I sprayed the oil at the Torrington bearing not because I think it needs a constant bath of oil but because it's at the center of the works. I think the oil will distribute outward from there.

There's probably benefit in spraying oil at the lower gear, or the idler, since they're spinning the fastest. But that would require more parts and I felt that was not a good trade-off.
