In light of Tony Allen's post about which motors were affected, I took a more thorough second look. The "plastic" in our failed version 2 motor was a blob of white grease. When I disassembled the gear box the gears were in fact all metal. My apologies for the incorrect information.

And, before I give out more incorrect information, I'll put the output shaft on a hardness tester to get some non-anecdotal data.
