3. Press the output shaft through the bearing
cones. Discard the used bearing cones.
Bearing Puller Method
1. Place a used bearing cup on the inner bearing
cone.
2. Install a bearing puller tool over the output
shaft. Figure 3.15. The bearing cup supports
the output shaft

3. Remove the bearing cones from the output
shaft. Discard the bearing cones.
4. If necessary, use a brass drift and hammer
to carefully tap the inner cup from the cage.
Discard the cup. Figure 3.16.

Removal and Disassembly
Measure Ring Gear Backlash
Before the differential be disassembled, use a
dial indicator to measure and record ring gear
backlash at three locations on the ring gear.
This will help you to correctly reassemble the
ring gear and drive pinion.
1. Rotate the differential in the stand to access
the ring gear teeth
2.Install a dial indicator onto the flange of the
differentialer. Place the tip of the indicator
against the drive side of a ring gear tooth.
Adjust the dial indicator to ZERO. Figure 3.17

INDICATOR
Figure 3.17
3. Read the dial indicator while you slightly rotate
the ring gear in both directions. When
you rotate the ring gear to measure the backlash,
the drive pinion must not move. Record
the reading on the dial indicator.
4. Repeat the procedure at two more locations
on the ring gear.
• If the smallest of the three measurements is
between 0.008” a 0.018” (0.20mm a 0.46mm)
for Series 145 or up 0.010” a 0.020” (0.25mm
a 0.51mm) for Series 160, replace the ring
gear and drive pinion as a set
Removal the Input Shaft and Inter-Axle
Differential Assembly
1. Rotate the differential in the support to access
the input shaft.
2. Remove the capscrews and the washers that
fasten the drive pinion cover to the differential.
Remove the cover. Remove all gasket
material from the cover and the differential.
