To say that they used the same motors might be to oversimplify a bit. If they applied larger wheels to accomodate larger gears, that meant larger gear cases -- which mant different gear cases. Then, larger bull gears on the axles usually meant smaller pinions on the motor shafts, which would have meant pulling the motor from the casing, pulling the armature from the motor, pulling the pinion from the armature, installing the new pinion, re-installing the armature, and hoping the motor would fit the new gear casing and that the gear-to-gear distance would be correct. And all this while changing wheels. Of course, they knew before starting what would work. I'll bet they used the whole motor, gear and casing assembly as a trade in for a whole new assembly which they dropped in. Finally, they didn't re-gear all of the E-8s. Maybe it easn't worth it?
