Ring And Pinion Wear Pattern

When the pinion is too far in towards the ring gear the pattern is low toward the base of the gear teeth.

Ring and pinion wear pattern.

Move the pinion deeper in towards the differential carrier add pinion shim. 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. Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation. Low contact pattern is concentrated in the root of the drive gear tooth.

The ring gear is too far in toward the pinion. Use gear marking compound to paint all of the ring gear teeth. Load the ring gear and run a full contact pattern check. Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows.

Ring and pinion gear pattern interpretation adjustment. Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns. The heel of the gear tooth is the portion of.

Begin by setting proper pinion bearing preload total turning preload and ring gear backlash. Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear.
