LUK claims to have information about the amount of tilt and angle movement of the secondary mass of the flywheel in their online documentation, but it is impossible to find.
On the phone, they said they don't publish the specs, and that the flywheel should just be replaced when the clutch is worn out.
So that means you don't know how worn your dual mass flywheel is unless you have some specs to compare to- which they don't provide.
So, a brand new LUK DMF061 (415 0263 100) has the following measurements;
free rotation of secondary mass to first friction - ~ 2 teeth (with associated inverted teeth)
rotation from first friction to spring-loading, and allowing spring-loading to return - ~ 1 tooth (with associated inverted tooth)
Friction after first friction to spring loading is considerably greater than with used flywheel.
Plate tilt - full tilt one way to other way, measured at edge of pressure plate mating surface to face of starter teeth - ~ 2.7mm (45.5mm-42.8)
The flywheel that came out of the car with 180k miles (on chassis, unsure how many on flywheel) has the following measurements
free rotation of secondary mass to first friction - ~ 2 teeth (with associated inverted teeth)
rotation from first friction to spring-loading, and allowing spring-loading to return - ~ 1 tooth (with associated inverted tooth)
Plate tilt - full tilt one way to other way, measured at edge of pressure plate mating surface to face of starter teeth - ~ 3.3mm (46.4mm-43.1)
