MAINTENANCE MANUAL
1. Place the differential case in the press so that
the threaded end of the pinion is UP. Place
supports under the ange 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.
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 dif-
ferential 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 en-
gage the splines inside the gear. Figure 5.12.
CAUTION
DO NOT APPLY PRESSURE AFTER THE IN-
NER BEARING CONE TOUCHES THE INNER
