Load the ring gear and run a full contact pattern check.
Ring and pinion wear pattern chart.
Begin by setting proper pinion bearing preload total turning preload and ring gear backlash.
Use gear marking compound to paint all of the ring gear teeth.
Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up.
Ring gear tooth profile face hobbing face milling the toe of the gear is the portion of the tooth surface at the end towards the center.
The heel of the gear tooth is the portion of.
This pattern indicates excessive pinion depth.
Toe contact pattern is concentrated off the toe end of the drive gear tooth.
For more in depth information about ring and pinion gear patterns and how.
Teeth on the gear set are excessively worn chipped or broken.
After the gears are installed using a pinion depth setting tool you should always check the wear pattern using a marking compound.
Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows.
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 images below illustrate both acceptable and unacceptable ring and pinion gear patterns.
You should see the wear pattern closer to the toe of the tooth with most gear sets.
Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear.
