A method for inspecting contact between mating gears that includes applying a mixture to teeth of a first gear, teeth of a second gear, or the teeth of both the first and second gears. The mixture includes a lubricating oil and a fluorescing dye. The first gear is rotated to drive the second gear. While the second gear is being driven by the first gear, electromagnetic radiation, such as ultra-violet radiation, is applied to the teeth of at least one of the first and second gears to cause the teeth to fluoresce. The fluorescing teeth of the second gear are inspected to identify a tooth inspection zone that approximates a zone of contact between the teeth of the first and second gears.
