defective 'new' flywheel...? Help please.?

Today I picked up a new Luk DMFW and was planning to take it to get it balanced as an assembly along with the new Sachs pressure plate.

After removing the old one (for comparison purposes), first I noticed that the old one was very stiff and hardly moved between 2-3 mm...

However, the big surprise was the 'new one' because it has too much free play between the left and right limits (before it starts to provide resistance).

If you position the top of the flywheel all the way to the left side of the free play (before offering any resistance), you can then move it all the way to the right about 15mm, before the tension starts to build again to the right.

In other words, you have between 15 to 20mm of play from one side to the other and at each end of the free play you can push the top (with spring tension about 5mm) before returns to that side of the free play.

This does not seem right however, this is the very first time that I hold a DMFW on my hands, is this normal..?

Any comments will be greatly appreciated before I call the store where I bought the new Luk to complain...

Thank you in advance for your comments.
Gilles
