How To Read A Differential Gear Pattern: A Beginner's Guide. ( Gear Tooth Contact Pattern ) In this video I'm going to show you how to correctly read a differential gear pattern. Reading a differential gear pattern is done by painting gear marking compound on the ring gear and rotating the pinion until the paint on the ring gear is removed by the pinion gear. You can analyze the mark in the paint to tell you how the ring gear and the pinion gear are meshing with one another. Based on what you see in the gear pattern tells you what adjustments you need to make to the differential.
