Clearance Angle Inspection
If the vehicle is equipped with a dual mass flywheel, perform the following inspection.
The clearance inspection is to check if the secondary flywheel exhibits a normal amount of movement in relation to the primary flywheel, in both directions, as the internal flange contacts the ARC springs.
Before the inspection of the clearance angle, the dual mass flywheel should be rotated several times in a clockwise and counter clockwise direction. There may be light scrubbing, clicking or metallic noises as the flywheel is rotated in each direction.
If the flywheel cannot be moved in either direction or exhibits a binding condition, the flywheel is defective and must be replaced.
- Rotate secondary flywheel counter clockwise until the counterforce (spring force) is clearly noticeable
- Release secondary flywheel slowly until there is no spring force on the flywheel.
Mark position with a vertical line on secondary flywheel (1) and on toothed ring (2).
Rotate secondary flywheel clockwise until the counterforce (spring force) is clearly noticeable.
- Release secondary flywheel slowly until there is no spring force on the flywheel.
Apply a new marking on secondary flywheel (1) on the height of the marking on the toothed ring for starter (3).
- Count the number of teeth from marked tooth up to the height of the first marking on secondary flywheel (2).
- For the functional movement of the secondary flywheel, up to 6 teeth are allowed.
- If the movement exceeds 6 teeth, the flywheel must be replaced.
