8 | Position torque converter (5) so that the turbine shaft points upwards | Secure the torque converter by placing blocks of wood or similar supports underneath to prevent it from tipping over. The torque converter must always be turned by two people. It weighs between 50 and 60 kg depending on version. | |
9 | Remove shim (6) from torque converter (5) or from turbine shaft | ||
10 | Remove spacer ring (7) from stator hollow shaft | Check spacer ring for damage and replace if necessary. | |
| Install | ||
11 | Fit spacer ring (7) on stator hollow shaft and position with no axial play | ||
12 | Align plain compression ring (8) centrally | Check plain compression ring for damage and replace if necessary. | |
| Measure | ||
13 | Measure and adjust axial play of torque converter (5) | Determine thickness of shim (6). | |

| Measure | ||
15 | Measure installed dimension of torque converter (5) | ||
16 | Compare measured value for installed dimension with both the installation dimension noted down before the torque converter (5) was removed and the specified installed dimension. | If the measured value for the installed dimension is too large, a spacer ring must be removed from the stator hollow shaft. If the measured value for the installed dimension is too small, a second spacer ring must be fitted on the stator hollow shaft. The thickness of one spacer ring is | |
17 | Screw torque converter (5) onto input shaft | Repeat steps 15 and 16. | |
