SPACER- AVAILABLE IN DIFERENT SIZES TO ADJUST PRELOAD. SPACER - ONLY AVAILABLE IN ONE SIZE. 1. Place the differential case in the press so that the threaded end of the pinion is UP. Place supports under the flange of the differential case so that the case is level. Place a wood block under the head of the pinion. Figure 5.11. 2. Press the drive pinion out of the outer bearing cone. Remove the cone. Figure 5.11. SUPPORT WOOD BLOCK MAINTENANCE MANUAL OUTER BEAR- ING ASSEMBLY INNER BEARING ASSEMBLY PRESS Figure 5.10 OUTER BEARING CONE DRIVE PINION SUPPORT Figure 5.11 Assembly and Installation 3. Turn the differential case so that the bearing caps of the differential case are UP. Place supports under the differential case so that the case is level. 4. Place the helical driven gear over the pinion bore in the differential case so that the splines inside the gear are toward the front of the differential case. Place the large spacer on top of the helical driven gear so that the spacer is toward the inner bearing cap. Figure 5.12. 5. Install the drive pinion into the helical driven gear. Verify that the splines on the pinion engage the splines inside the gear. Figure 5.12. CAUTION PRESS SUPPORT SUPPORT DRIVE PINON SPACER HELICAL DRIVEN GEAR Figure 5.12 DO NOT APPLY PRESSURE AFTER THE IN- NER BEARING CONE TOUCHES THE INNER BEARING CAP. IF MORE PRESSURE IS AP- PLIED, THE CAP, CONE AND DRIVE PINION WILL BE DAMAGED. 45
Assembly and Installation 6. Place a protector in the head of the drive pinion. Use a press to install the pinion into the differential case so that the inner bearing cone touches the bearing cap. At this time, the helical driven gear will not be completely installed on the drive pinion. Figure 5.12. 7. Place the differential case in the press so that the threaded end of the pinion is toward the TOP. Place supports under the flange of the differential case so that the case is level. Place a wood block under the head of the drive pinion so the inner pinion bearing cone touches the inner bearing cap. Figure 5.13. CAUTION DO NOT APPLY PRESSURE AFTER THE HELICAL DRIVEN GEAR TOUCHES THE SPACER IN FRONT OF THE INNER BEAR- ING ON THE DRIVE PINION. IF PRESSURE IS APPLIED AFTER THE PARTS TOUCH EACH OTHER, THE GEAR WILL DAMAGE THE SPACER. 8. Use a press and a sleeve to completely install the helical driven gear onto the drive pinion. Use a sleeve on the hub of the gear that fits inside the pinion bore. Press the gear into the drive pinion until the gear touches the spacer. Figure 5.13. HELICAL DRIVEN GEAR WOOD BLOCK AND END OF DRIVE PIN- ION MUST TOUCH SUPPORT WOOD BLOCK PRESS SLEEVE SUPPORT Figure 5.13 9. Cut two pieces of lead or solder approximately 0.5625-inch (14 mm) long and 0.625inch (16 mm) wide. Use the two pieces of solder or lead as gauge blocks to determine the correct thickness of the spacer between the helical driven gear and the outer bearing. 10. Place the two pieces of lead or solder so that the pieces are opposite each other on top of the helical driven gear. 11. Place the outer bearing cone into the cap over the two pieces of lead or solder on top of the helical driven 12. Remove the support from the flange of the differential case. Place a sleeve on top of the outer bearing cone. Use a press to apply 2 tons (1814 kg) of force to the outer bearing cone. The force of the press compresses the lead or solder pieces to the correct size. Do not apply more than 2 tons (1814 kg) of force. Figure 5.14. PIECES OF LEAD OR SOLDER PRESS - DO NOT APLLY MORE THAN TWO TONS (1814Kg) OF PRESSURE SLEEVE WOOD BLOCK - MUST SUPPORT HEAD OF PINON OUTER BEARIN CONE HELICAL DRIVEN GEAR Figure 5.14 13. Release the pressure and remove the wood block from under the head of the drive pinion. 46 MAINTENANCE MANUAL
