Although I don't know how new this pinion was, I can say that it was making a minor "clackclack" sound before the failure. However, this pinion didn't need any more reason to break, given that it was a 12 tooth made 7075 aluminum and was taking the load of two CIMs.
After replacing it with a steel equivalent, the gearbox has been working great so far. (Fingers crossed)

There's "FIRST the organization" and then there's "FIRST the vision for the future through a set of ideals". I've grown somewhat skeptical of the former in recent years, but, after 10 years, I'd still throw myself in front of a bus for the latter. - Rich Kressly [more]
