Dual Mass Flywheel.

[Pcot]

The dual mass flywheel will eventually fail, and start to throw bits into the starter motor. Early transit's (pre 2000) suffered from clutch judder, hence the fitting of the DMF.
I've just had mine replaced last week. It was cheaper to have a solid flywheel fitted rather than replace with a DMF.

Fwiw, From what i have been told from a fairly high person at luk, The main idea of a dmf was to stop/reduce the amount of stress to travel along the crank etc. Reports have been heard of dmf being converted to single mass and cranks have become out of balance or something along them lines and therefore the engine being naffed, This was however a couple of years ago now so that is not gospel info.

On a single mass flywheel the clutch pressure plate tends to have springs in it to cushion the driveline, with a dual-mass the pressure plate is solid and the springs are in the flywheel. There must be advantages to doing it that way since the old way seems cheaper & easier...?

I have a 2003 Peugeot 406 Hdi 2.0 110 EST. Had a DM flywheel changed to a solid one 9 years ago. Have covered 90,000 miles and even towed my 1000 kg caravan. Been good as gold. At the time a lot of local taxi drivers were doing the same.
