5 | Remove the yoke coupling (2) | Puller | |
6 | Remove the pinion (11) | To remove the pinion (11), reinstall the collar nut (1) to protect the pinion thread. Tap the pinion shaft with the aid of a hammer and a brass billet until it is removed. | |
7 | Remove the radial seal (3) | ||
8 | Remove the differential housing (6), the tapered roller bearing (4), the spacer washer (7) and the spacer bushing (8) | ||
9 | Remove the outer races of the tapered roller bearings (5, 9) from the differential housing (6) | Use a hammer and a brass billet. | |
| Check | ||
10 | Check the tapered roller bearings (4, 10) for wear and damages |
| |
If needed, replace the tapered roller bearings (4, 10). | |||
| |||
Remove the tapered roller bearing (10) from the pinion. | |||
| Install | ||
11 | Install the tapered roller bearings (10) on the pinion (11) |

When installing the outer race of the tapered roller bearing (9) on the tapered roller bearing (10), it is necessary to define the drive pinion assembly measure (11). | |||
Warning | Risk of injury. Skin or eye injuries may result when handling hot or glowing objects. | Wear protective gloves, protective clothing and safety glasses, if necessary. | |
13 | Install the pinion (11), the outer race of the tapered roller bearing (5), the spacer bushing (8), the spacer washer (7) and the tapered roller bearing (4) on the differential housing (6) |
| |
Determine the spacer washer thickness (7) for the correct frictional torque of the pinion. | |||
To install the tapered roller bearing (4), heat it to approximately 80°C. | |||
14 | Install the radial seal (3) | Use a new radial seal. | |
Apply a sealing agent to the outer surface of the seal. | |||
