The procedures to the right are to be used to establish proper
gear tooth pattern after assembly of the carrier is complete.
NOTE: If matched sets are being reused,
measure and record backlash before disas-
sembly, and reassemble to the same backlash.
This will match ring and pinion gears to the
established wear patterns. Hand rolled pat-
terns will cover less area than the gear pattern
established by previous service.
STEP 1. Paint 1/4 ring gear with marking compound on
both the drive and coast side.
STEP 2. Rotate ring gear at least one complete revolution in
both directions while load is being applied.
NOTE: Tooth contact pattern, on this axle model, can be moved only by adjusting backlash.
The contact pattern can be moved in the direction of heel-to-toe, and toe-to-heel; Depth of
the pattern cannot be adjusted. If an acceptable tooth contact pattern cannot be established
within limits of backlash, contact Spicer Service at 1-800-666-8688.
