Ring And Pinion Wear Pattern

Low contact pattern is concentrated in the root of the drive gear tooth.

Ring and pinion wear pattern.

Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear. Use gear marking compound to paint all of the ring gear teeth. Move the pinion deeper in towards the differential carrier add pinion shim. Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up.

The heel of the gear tooth is the portion of. Move the pinion out away from the differential carrier subtract pinion shim. When the pinion is too far in towards the ring gear the pattern is low toward the base of the gear teeth. For more in depth information about ring and pinion gear patterns and how.

Load the ring gear and run a full contact pattern check. Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns. Ring and pinion gear pattern interpretation adjustment.

The ring gear is too far in toward the pinion. 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.
