Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation.
Ring and pinion pattern chart.
Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows.
For more in depth information about ring and pinion gear patterns and how.
Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up.
When the pinion is too far in towards the ring gear the pattern is low toward the base of the gear teeth.
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.
The heel of the gear tooth is the portion of.
Ring and pinion gear pattern interpretation adjustment.
The ring gear is too far in toward the pinion.
Low contact pattern is concentrated in the root of the drive gear tooth.
Move the pinion out away from the differential carrier subtract pinion shim.
This pattern indicates excessive pinion depth.
Ring gear and pinion tooth pattern interpretation.
When setting the pinion position many of the service manuals required a final pinion position check by using gauges that verified the dimension from the center line of the differential carrier center line of ring gear to the face of the pinion button.
Move the pinion deeper in towards the differential carrier add pinion shim.
Use gear marking compound to paint all of the ring gear teeth.
