Begin by setting proper pinion bearing preload total turning preload and ring gear backlash.
Ring and pinion gear pattern chart.
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.
The ring gear is too far in toward the pinion.
Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation.
Load the ring gear and run a full contact pattern check.
Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear.
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 images below illustrate both acceptable and unacceptable ring and pinion gear patterns.
Move the ring gear closer to the pinion decrease backlash while maintaining minimum backlash.
Ring and pinion gear pattern interpretation adjustment.
Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows.
Use gear marking compound to paint all of the ring gear teeth.
The heel of the gear tooth is the portion of.
When the pinion is too far in towards the ring gear the pattern is low toward the base of the gear teeth.
Move the ring gear away from the pinion increase backlash while maintaining minimum backlash.
