The ring and pinion tooth contact pattern is used to double check ring and pinion adjustment.

Ring and pinion contact pattern.

For more in depth information about ring and pinion gear patterns and how. Ring gear contact pattern interpretation of face hobbed uniform tooth depth gear teeth proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation. Ring and pinion gear pattern interpretation adjustment. The differential ring gear backlash is correct.

Begin by setting proper pinion bearing preload total turning preload and ring gear backlash. The ring gear is too far in toward the pinion. Use gear marking compound to paint all of the ring gear. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns.

Moving the ring gear toward the pinion removes the backlash and moves the contact pattern closer to the toe. Toe contact pattern is concentrated off the toe end of the drive gear tooth. Move the ring gear away from the pinion increase backlash while maintaining minimum backlash. This pattern indicates excessive.

Ring and pinion tooth contact pattern. A thicker drive pinion shim is needed. Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up. This is the opposite of c.

A contact pattern that is worn in the center of the differential ring gear tooth toward the heel. Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear.
