Bill,
I know that there are multiple Fisher Price gearboxes out there, but the only ones that were supposed to be provided by FIRST in the offficial kit are the ones with 16 teeth on the motor pinion.
As to the rest of the gears being the same (and therefore there are different gear housings), are you sure about that?
My understanding way back last fall when I was talking to the F-P guys almost every other day was that the gearbox was common and only the first stage changed (that is, the pinion on the motor and the cluster that it mates with). If this is correct then the 19 tooth version would have to mate with a gear that was 3 teeth bigger than the gear that mates with the 16 tooth pinion.
I am quite curious...
...If you get a chance, would you mind carefully comparing the two gearboxes?
Joe J.
