The clutch disc used with the dual-mass diesel flywheel does not have any internal springs or dampers. The clutch disc used with the newer single-mass diesel flywheel incorporates a series of springs/dampers.

So.... you have to be sure what flywheel you have before ordering/installing a replacement clutch disc.

are one and two peice rear mains the same as far as the flywheel

mark
The same flywheel/flexplate can be used on either rear main seal engine.
