I have been doing mech boxes for almost 13 years, and have never seen gears warp. However, this is not to say it is not possible, as at the present moment I am trying to figure out how a SystemA torque up sector gear came from th factory missing the last tooth. As well, the spur gear has four bent teeth, one bent tooth every quarter around the gear equally spaced, while the bevel gear is mint.
Out of all the years I've been handeling SystemA internals, I have never encountered this before.
Typically the center hole in the bushing will wear oval causing the gears to mess incorrectly and cause breakage, but warping the gears....that would be a factory defect in my opinion, not something related to usage.
