Note: The inner ring and outer race of a tapered roller bearing are matched. Don't get confused!
2. Press the outer ring (cage) of the tapered roller bearing without an adjusting shim using a mandrel (MP3-464 (30-205)) into the gearbox housing.
3. Insert the differential into the clutch housing.
4. After installing the gearbox housing, tighten the 5 mounting bolts to a tightening torque of 25 Nm.
5. Install a dial indicator with a pre-tension of 1 mm and adjust it to "0".
6. Move the differential up and down, read the gap size from the deviation indicator and mark it (example: 0.70 mm).
7. Determining the thickness of the adjusting shim.
The specified pre-tension is achieved by adding a constant value of 0.25 mm to the measured value.
Example:
Measured value 0.70 mm + indentation (constant value) 0.25 mm = shim thickness 0.95 mm.
Example:
| Measured bearing clearance value | Adjusting shim thickness according to the table |
| 0.70 mm | 0.95 mm |
Remove the gearbox housing, remove the outer race of the tapered roller bearing from the gearbox housing.
The following adjustment shims are available:
| Bearing clearance | Adjusting shim |
| Measured value (mm) | Thickness (mm) |
| 0.359...0.430 | 0.65 |
| 0.431... 0.480 | 0.70 |
| 0.481... 0.530 | 0.75 |
| 0.531...0.580 | 0.80 |
| 0.581...0.630 | 0.85 |
| 0.631...0.680 | 0.90 |
| 0.681...0.730 | 0.95 |
| 0.731...0.780 | 1.00 |
| 0.781...0.830 | 1.05 |
| 0.831...0.880 | 1.10 |
| 0.881...0.930 | 1.15 |
| 0.931...0.980 | 1.20 |
| 0.981...1.030 | 1.25 |
| 1.031...1.080 | 1.30 |
| 1.081...1.130 | 1.35 |
| 1.131... 1.250 | 1.40 |

A. Counterpoise.; B. Puller with grip of the part from the inside 46... 58 mm
8. Insert adjusting shims of the required thickness; first the one that is the thickest of all.
9. If the required thickness is greater than the thickness of the specified gasket, it is possible to use two gaskets, the total thickness of which corresponds to the required thickness. Different tolerances allow precise selection of a washer of the required thickness.
10. Press in the outer ring of the tapered roller bearing together with the installed adjusting shim (using 0.95 mm as an example) into the gearbox housing.
11. Install the gearbox housing and tighten its mounting bolts.
