RC,

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.

Large OD Count Small OD Count
Gear #1 2.283” 72 teeth .870” 25 teeth
Gear #2 2.510” 79 teeth .919” 19 teeth
Gear #3 2.634” 62 teeth 1.300” 12 teeth
Gear #4 3.501” 38 teeth

Hope this helps,

Ivan
