The location of the damage observed on the low-speed pinion (Fig. 7) corresponds to the damage observed on its mating gear. However, the level of damage on the low-speed pinion is much more se vere than that on the mating, low-speed gear. Since the pinion sees many more cycles than the gear, the disparity in the level of damage is expected.
