Dual Mass flywheel?

[Frozen Redneck]

Ok so I've done my homework etc etc... I just don't know if my truck has a dual mass flywheel or not. I pulled the cover off the bell housing, and it seems to me it's single.. but in all my travels i've never encounter a dual mass flywheel that I can recall, somebody have a picture? Or is there something specific to look for? Thanks

Any ideas? Maybe some characteristics of the single mass? I know the gear noise, which mine is obnoxious, which is one of the things that leads me to believe it is in fact a single. But it also bucks hard when I take off pulling heavy. Under about 20-23K it's fine, but I pull some monster loads, upwards of 40K sometimes hauling equipment. Is that just clutches in general, or is that a single mass single disc clutch thing? Or did the dual masses even help with smoother engagement under heavy load?

I'm not sure but if you take off the cover with it shut off then get a pry bar and on the teeth of your flywheel pry a little and if the teeth move and the engine does not you have a dual mass fly wheel

The dual mass flywheel will have the dampening springs in the flywheel itself (and none in the clutch disk), where the single mass units will have the springs in the clutch disk. The DMFW will also have 2 masses that can be slightly counter-rotated agaist each other (about 5/8" or so). Cheers!
