A. Lift the input shaft assembly until the bearing
cage is separated from the differential
assembly. If necessary, tap on the bearing
cage with a brass or plastic mallet to separate
the cage of differential. Figure 3.22.
B. For 160 Series differential and 145 Series
differential manufactured after September
1998, slowly lift the input shaft assembly.
• If the input shaft assembly comes out of the
differential easily; remove the assembly.
• If the input shaft assembly cannot be removed
easily: The inter-axle differential
case must be rotated. Rotate the input
shaft until one of the notches on the case
is aligned over the helical driven gear. Remove
the input shaft assembly from the differential.
