| 3. Check a condition of all details and, if necessary, replace them. |
| 4. Removal of separate details is given below. |
| 5. Assembly is carried out to the sequences of the return to removal. |
| 6. Installation of separate details is given below. |
|
Removal of bearings of differential
Prevention
Do not remove the bearing if its replacement is not required.
| PERFORMANCE ORDER |
|
1. Special OK130 171 013 adaptation remove the bearing from the opposite conducted gear wheel.
|
| 2. Special OK130 171 013 adaptation remove the bearing from the conducted gear wheel. |
Prevention
Be careful not to drop a differential box.
|
|
|
3. Special OK670 990 AA0 adaptation remove an internal ring of the bearing from the opposite conducted gear wheel. |
| 4. Special OK670 990 AA0 adaptation remove an internal ring of the bearing from the conducted gear wheel. |

Check
| PERFORMANCE ORDER |
|
Check a condition of all details of differential and, if necessary, replace them. |
|
Installation of the conducted gear wheel
| PERFORMANCE ORDER |
|
|
Examine a gear wreath of the conducted gear wheel on lack of wear and cracks. If it was carried out it is replaced details, adjust a preliminary tightness of the bearing. |
|
Installation of bearings
| PERFORMANCE ORDER |
|
1. Check the bearing for absence of damage and smoothness of rotation. If the bearing was removed, replace rings of bearings and adjust a preliminary tightness of the bearing. |
|
2. Install by special OK900 175 AA1 adaptation the new bearing from the conducted gear wheel. |
| 3. Install the speedometer drive. |
|
4. Install by special OK900 175 AA1 adaptation the new bearing from the opposite conducted gear wheel. |
|
5. Establish a new cylindrical pin as shown in the drawing to record an axis of satellites. |
|
Check of a side play between a semi-axial gear wheel and the satellite
| PERFORMANCE ORDER |
| 1. Establish the left and right power shafts in differential. |
| 2. Install power shafts in V-shaped blocks. |
|
3. Measure by the indicator of hour type a side play.
Side play: 0-0,1 mm
|
| 4. If the side play exceeds admissible limits, replace the damaged and worn-out details. |
