Install new inner race (Figure 5, Item 4) on journal adjacent to hydrostatic drive gear (Figure 5, Item 3) if old bearing was removed. 3. Do a check to make sure cage and outer race (Figure 5, Item 8) for inner race (Figure 5, Item 4) is in the left end of center housing assembly (Figure 5, Item 1). Also do a check to make sure cage and outer race for inner bearing race (Figure 5, Item 5) is in the left cover assembly. 4. Install range input drive gear (Figure 5, Item 2) and hydrostatic drive gear (Figure 5, Item 3) on bevel gear driven shaft (Figure 5, Item 9) with hydrostatic drive gear (Figure 5, Item 3) down. 5.
