I was looking for the specs on the gears that inside the “2009 Black FP KOP Transmission”. I don’t have access to the shop till next week, but a local team needed some plates machined out because their banebot planetaries finally kicked the bucket. All the gears were grinded and worn out, very kewl to see. I just needed the teeth count and the DP/module of each gear.
If you can wait until Tuesday evening and want to PM me an email address, I can send you a picture of the gears and you can count teeth. I’ll also measure the OD of each gear and you can work backwards to the rest. Unfortunately, that’s about the best I can do for you.
Here are the ODs of the gears and the tooth counts. As far as I acn tell, all of the gears in the FPs are the same regardless of color. The motor pinion may change. In the 2009 KoP I think the motor pinion had 16 teeth. The other option is 19 teeth. I don’t have a 16 to measure, but the 19 tooth one measures .673" OD.
Adam is probably right about the .8 mod but that would only be correct for the pinion and the first 2 plastic gears. Second to third is a larger tooth and third to fourth is larger yet.
Here are some approximate CC distances measured from the one in my basement:
Motor to #1 1.375” approximately #1 to #2 1.630” measured across the idler shafts and subtracted .375” #2 to #3 1.707” also measured across the shafts. #3 to #4 2.247” approximately because there isn’t much to measure to on the last gear.
