The best illustrations and explanations I have found are in the older "Motors" manual. As stated the process has a lot of steps to get the right gear contact pattern. Instead of white lead I have used cold GOJO for years as it is more visible to old eyesight and cleans up easily for repeat patterns. Room temp GOJO gets brown, runny, and useless as an indicator. Buy an inch pound torque wrench or a fish scale to set bearing preload which is important.
