This is Lionels newer gearbox design. Theres an intermediate gear between the worm and the axle gear.
This intermediate gear rides on a shaft that spins in bushings on either side of the gearbox. Grease that finds its way up to the worm eventually migrates to one end of the shaft with the pitch of the gears. This end of the shaft also seems to get the brunt of the torque from the gear pitch as well.
I have no way of knowing if the bushings are bronze or brass, they appear to be brass, more "orangy" in color?.
Lionels best intentions may not have made it to the factory. (No surprise there)
