Dual-mass Flywheel (MTX)/Drive Plate (ATX) Installation Bolt Disassembly Note Dual-mass flywheel installation bolt (MTX): Notes

Hold the crankshaft using the SST (49 E011 1A0) .
Loosen the bolts uniformly and gradually in the order shown in the figure.
NOTE:
- If the bolt installation holes are not positioned properly, perform the following procedure:

1. Install the SST (49 S120 710) to the dual-mass flywheel.
2. Rotate the dual-mass flywheel (secondary flywheel side) using the SST (49 S120 710) .
3. When the bolt installation holes are positioned properly, hold the position and remove one of the bolts.

4. After removing the bolt, set up the SST (49 G033 102) to lock the dual-mass flywheel (secondary flywheel side) against rotation.
  WARNING:
  - If all of the bolts are removed without locking the dual-mass flywheel (secondary flywheel side) against rotation, the dual-mass flywheel (primary or secondary flywheel side) may rotate, resulting in injury. Therefore, always set up the SST (49 G033 102).
  - When the bolts are removed from the dual-mass flywheel, always cover the bolt holes using tape. If the SST (49 G033 102) is removed while the operator's finger is inserted in the bolt hole, the dual-mass flywheel may rotate and the operator could be injured.
