Why, why, why, would they do this?!
A 30c bushing could have prevented all of this.
Or a 10c c-clip on the side of the intermediate shaft that has the small output gear.
My physics is escaping me at the moment, but if I remember the right hand rule correctly all they had to do was put the output gear on the other side and shift everything right. Then the torque force would have kept the intermediate gear against the final gear when running forward.
I wonder if this is why the KLine models had the motor output shaft rear facing.
