8. Use a rubber mallet to fully seat the threaded bearing cups. 9. With a dial indicator, check the ring and pinion backlash. Set the backlash from 0.010" to 0.012". This will give you room to adjust the contact pattern, if necessary. 10. Remover the adjuster plates and threaded rod assembly. 11. Install the carrier differential bearing caps and capscrews. Make curtain there is no gap between the carrier cap and the carrier surface.
12. Use an impact gun to securely fasten down the (4) carrier cap fasteners. Note: Do not completely torque them down at this point. 13. Recheck the backlash. a. New Gearing: The backlash should be between 0.008" and 0.018" (0.20 and 0.46 mm). b. Used Gearing: The backlash should be reset to what it was at the time of disassembly. Note: If you have too much backlash, move the ring gear closer to the pinion. Count the number of notches you back off the plain half threaded cup. Each notch equals about 0.003" (0.08 mm) of backlash. IMPORTANT: In order to maintain the differential bearing preload, you will need to turn the flange half threaded cup the same amount in the same direction. If you need more backlash, reverse the procedure. 14. After the gear pattern is correctly set. Torque the carrier cap fasteners as specified below.
