Dual mass flywheel

Don't know if the LNF flywheel looks like this, but I found it interesting anyway.

I have dual mass flywheels in my diesel pickups, they have been around for quite a while.

The most interesting thing I learned is that, besides the friction surface, they can "wear out" (i.e. bushings fail).

I wore out four of the six springs in my 1992 Chevy diesel which cause me to break the counter shaft in my tranny.  I had a mechanical injector pump which has a set screw in the bottom of the housing and if you turn it all the way until it stops, it turns up the maximum fuel by a lot.  Then I put a booster spring on the waste gate of the turbo charger. Instead of nine psi boost, I had 18 psi. With 21.5 to one compression ratio and the timing of the injector pump advanced slightly, the truck was ungodly fast which was hard on the springs in the dual mass flywheel.

Innovative designs make for innovative failures! Usually more expensive to begin with also. Oh well, bragging rights I suppose.
