17. Measure the rotational freeplay XX between the 2 reference marks on the primary mass of the dual mass flywheel. If the rotational freeplay
exceeds 19 mm (0.750 in), install a new dual mass flywheel.
18. With the dual mass flywheel installed on the engine, inspect the dual mass flywheel internal spring operation using the following Steps 19 through
21.
19. Install the Flywheel Holding Tool.
20. Using a suitable long screwdriver or bar, firmly rotate the secondary mass clockwise. The secondary mass should begin to engage the internal
spring past the freeplay movement of 19 mm (0.750 in) maximum. The secondary mass should continue to rotate and engage the internal spring
with increasing spring pressure. If the secondary mass does not rotate, install a new dual mass flywheel.
21. Using a suitable long screwdriver or bar, firmly rotate the secondary mass counterclockwise. The secondary mass should begin to engage the
internal spring past the freeplay movement of 19 mm (0.750 in) maximum. The secondary mass should continue to rotate and engage the internal
spring with increasing spring pressure. If the secondary mass does not rotate, install a new dual mass flywheel.
22. Inspect the dual mass flywheel when removed from the engine and placed on a bench, using the following Steps 23 and 24.
23. NOTE: Blocks must be placed under the dual mass flywheel to make sure it is level and stable.
Remove the dual mass flywheel and place it on a firm and level surface.
