Tooth Contact
Gear tooth contact pattern check is necessary to verify correct
relationship between ring gear and drive pinion.
Hypoid gear sets which are not positioned properly in relation to
one another may be noisy, or have short life span or both. With a
pattern check, the most desirable contact for low noise level and
long life can be assured.
1. Thoroughly clear ring gear and dive pinion teeth.
2. Sparingly apply a mixture of powdered ferric oxide and oil or
equivalent to 3 or 4 teeth of ring gear drive side.
3. Hold companion flange steady by hand and rotate the ring gear
in both directions.
