INSTALL HYDROSTATIC DRIVE GEAR

NOTE

Hydrostatic drive gear may be installed either side f rst.

1. Install hydrostatic drive gear (Figure 5, Item 3) on shaft of range input drive gear (Figure 5, Item 2) if gears were

separated. Push hydrostatic drive gear (Figure 5, Item 3) to shoulder.

2. 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. Move gears (Figure 5, Item 2) and (Figure 5, Item 3) left and right until inner splines on hydrostatic drive gear

(Figure 5, Item 3) connect with splines on bevel gear driven shaft (Figure 5, Item 9), and teeth on hydrostatic

drive gear (Figure 5, Item 3) connect with teeth on hydrostatic idler gear (Figure 5, Item 10).

6. Continue to move gears (Figure 5, Item 2) and (Figure 5, Item 3) left and right until teeth on range input drive

gear (Figure 5, Item 2) connect with teeth on range input driven gear (Figure 5, Item 6).

7. Push down on range input drive gear (Figure 5, Item 2) to install gears (Figure 5, Item 2) and (Figure 5,
