Installing a set of ring and pinion gears is a job even the most seasoned mechanics get nervous about, and one of the most important aspects of the project is ensuring that your gears are meshing together properly, to avoid excessive noise, vibration, and premature wear.

The process of setting your ring and pinion gears involves painting the gear teeth, rotating the pinion, and then visually inspecting where and how the gears are meshing. You then make the appropriate adjustments.
