Notes on dismantling
Removal of bearings of differential
| PERFORMANCE ORDER |  | 1. Special adaptation OK130 and OK130 92 375 175 A18 remove the bearing from the side opposite the driven gear. |
A warning  Do not remove the ball bearings unless it must be replaced.
|
|
The inner ring of the bearing semiaxial
A warning Be careful not to drop a differential box.
| PERFORMANCE ORDER |  | Special adaptation OK130 175 aa0 remove the inner ring of the bearing of the half. | |
|
Bearing on the crown wheel
| PERFORMANCE ORDER |  | Special adaptation OK670 990 aa0 remove the bearing from the driven gear. | |
|
Check
| PERFORMANCE ORDER | | Check the condition of all the components of the differential and, if necessary, replace them. | |
|
Driven gear
| PERFORMANCE ORDER |  | Inspect the ring gear driven gear for wear and cracks.
If replacement parts, adjust the bearing preload. | |
|
Bearing
| PERFORMANCE ORDER |  | Check the bearing on absence of damages and smoothness of rotation. If the bearing is removed, replace the bearing rings and adjust the bearing preload. | |
|
Preliminary checks
Backlash side gear and satellite
Measure the backlash as follows.
| PERFORMANCE ORDER | | 1. Install the left and right drive shafts in the differential assembly. |  | 2. Place the drive shafts on V-shaped supports, as shown. | | 3. dial indicator, measure the backlash. Backlash: 0-0.1 mm | | 4. If the backlash exceeds admissible limits, replace the damaged and worn parts. |
|
Notes on assembly Bearing on the crown wheel
| PERFORMANCE ORDER |  | Special adaptation OK130 175 A12 establish the new bearing on the crown wheel. | |
|
Bearing on the opposite side of the driven gear
| PERFORMANCE ORDER |  | 1. Install the speedometer drive pinion. | | 2. Special adaptation OK130 175 A12 establish the new bearing on the side opposite the driven gear. |
|
Cylindrical pin
| PERFORMANCE ORDER |  | Install the new cylindrical pin, as shown in the figure to fix an axis of satellites. | |
|
Check the play between the side gear and the satellite
Measure the backlash in accordance with the following procedure:
| PERFORMANCE ORDER | | 1. Install the left and right drive shafts in the differential. |  | 2. Install the drive shafts in a V-shaped blocks, as shown in the figure. | | 3. dial indicator, measure the backlash. Backlash: 0-0.1 mm | | 4. If the backlash exceeds admissible limits, replace the damaged and worn parts. |
