Use gear marking compound to paint all of the ring gear. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns. Pinion mounting distance pmd adjustment on a face milled or 5 cut gear as pmd increases shim thickness decreases the pattern shifts toward the top face and towards the heel on the drive side and towards the toe on the coast side. Check the tooth contact pattern to diagnose or after installing and adjusting a new ring and pinion gearset.

Begin by setting proper pinion bearing preload total turning preload and ring gear backlash. See manufacturer or the gearset for exact specifications and special instructions before attempting to adjust the ring and pinion. 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 gear contact pattern interpretation of face hobbed uniform tooth depth gear teeth proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation.

Toe contact pattern is concentrated off the toe end of the drive gear tooth. 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. Move the ring gear away from the pinion increase backlash while maintaining minimum backlash. Gear contact patterns interpretation adjustment guide.
