Join me & Tool Girl Sam for the final stage of the Differential check - tooth contact pattern.
Here we use a special yellow Engineers contact paint to show the contact between the pinion & crown wheel teeth, an important aspect as incorrect contact between the teeth can cause premature wear, excessive noise & tooth failure (breakage).
I have also included information about how various contact pattern types can be interpreted and the adjustments that need to be made to improve the contact point.
