Reassembly and Installation
See Figure 9-9, “Input Shaft Assembly,” on page 165.
1. Using retaining ring pliers, install the retaining ring into the gearbox housing.
2. Insert the outer bearing spacer and press the outer bearing cup into place.

one used in the bearing carrier assembly is noticeably thicker.
3. Tap the inner bearing cup into place. Tap evenly around circumference to prevent
an uneven fit.

dle bearings, shifting collar, input gear, and bearing cone onto the shaft.
6. Insert the input shaft into the housing until the bearing cone contacts the bearing
cup.
7. Install the inner bearing spacer and shims onto the input shaft and press the
remaining bearing cone onto the input shaft.
