We've seen similar failures with the AndyMark kit gearboxes. We were never able to confirm how well they were initial greased, but when the gears look like that they probably aren't being greased well. The Andymark grease packets are quite small and may be applied by people who don't know how important it is. We now liberally grease them with our own big bucket of grease to ensure they don't run dry and haven't had another failure.
