Use gear marking compound to paint all of the ring gear teeth.
Ring and pinion pattern.
Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation.
For more in depth information about ring and pinion gear patterns and how to make adjustments see our installation instructions page.
Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear.
When the pinion is too far in towards the ring gear the pattern is low toward the base of the gear teeth.
Load the ring gear and run a full contact pattern check.
Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up.
Begin by setting proper pinion bearing preload total turning preload and ring gear backlash.
Toe contact pattern is concentrated off the toe end of the drive gear tooth.
The ring gear is too far in toward the pinion.
This pattern indicates excessive pinion depth.
