Jenny is remarkably complete considering it was retired in 1904.
I have a feeling the 6 bolt (6 stud really, with one broken off) drive gear bearing that's missing its cap was problematic. The shaft that extends to the left is sleeve coupled to a crudely made stub shaft and another friction bearing.
The babbit also looks to be in poor shape.
I'd wager it was done to help relieve radial stresses on the main 6 bolt bearing. I also suspect that this design issue probably resulted in it being retired.

You're right about the smaller bearing relieving stress on the 6 bolt main bearing. Transient torque loads would have created large radial stresses in the main bearing without the small *out-rigger* bearing. Still a journal bearing is an awful thing to use in a such an application hehe.
