I'm curious why you want this info. Are you trying to replicate the gear sets?
If you're just trying to run another motor through the drill transmision, say the Fischer Price, I might know exactly how to do that and have prints ready to send you
. We just pulled the drill gears using a bearing seperator and pin on an arbor press, then amade adapter shafts.
The reason I ask is as mentioned we adapted the drill trannies for use in this year's bot because we needed the high reduction over a short distance/small space for the FP's.
If I'm off base in my guess as to what you're doing please let me knowlet me know.
