move only by adjusting backlash. The tooth contact pattern can move only in the direction of heel-to-toe, and toe-to-heel. Depth of the tooth contact
pattern is not adjustable. Contact Spicer Service at 1-800-666-8688 for assistance if you are unable to establish an acceptable tooth contact pattern
within the limits of backlash.
