Inspection of Ring Gear Tooth Contact Pattern
Normal Contact
Apply gear-marking compound (prussian blue / red lead) on
the ring gear teeth. Rotate the ring gear and check the tooth
contact pattern.
Abnormal Contact

l
Drive pinion shaft is apart
from the ring gear
l
Noise can be occurred
Insufficient backlash (much)
l

worn
l
Noise can be occurred
Adjust backlash(Decrease backlash)
l
Select proper shim(s) to move the
drive pinion toward the ring gear
(toward toe)
Adjust backlash(Increase backlash)
l
