Dual mass flywheel

[Deuce_and_a_Half_Dragon]

So Im using the deuce as my topic for a research paper in my manual drivetrains class and one of the points is what type of flywheel is on the vehicle, ive used the search and come up with nothing, so the question is:

Does the deuce use a dualmass flywheel? Or is it a singlemass?

Thanks in advance

No, they only have a harmonic balancer on the front of the crankshaft.

Dual Mass flywheels are relatively new(1980's) technology.

only dual mass flywheels I've ever seen were for high RPM applications. the purpose being to lighten the rotating mass. the "dual" portion comes in because you don't want aluminum as your friction surface so an inlay of iron is used.

Okay, i was wondering because there was nothing in the TMs that said anything about the flywheel other than the friction plates bolted onto it (if I was reading the diagrams and such correctly) thanks guys quick and knowledgeable help as always

The deuce uses a single mass flywheel with a damped clutch disk. Dual mass flywheels are intended to make the power transmission smoother and ease shifting by allowing the use of a lighter clutch disk without damper springs and floating hub. The dual mass flywheel uses a spring damped second flywheel surface to do this. Smaller diesels use them generally, not big stuff.

Thanks guys, got what I needed

I know the ford 7.3 IDI's (88-94ish) Had dual mass flywheels with the zf5 transmissions. I have one sitting in my shed.

lol, thats actually what kinda got me asking about it, the sample report given to us guys doing 4x4's, and me doing a 6x6 , was on an '85 F-250 with an International 6.9, that just so happens to have a dual mass

duece uses a single mass flywheel..They use to use a dual mass on ford trucks with 7.3 or 6.9 not to many others used them .They didn't hold up to good even in just 1 ton trucks

Dual mass flywheels are a band aid to get an underspec'ed transmission with undersized gears to survive behind an engine that's got too many horsepower to be in a vehicle that's not stout enough to support an adequate driveline. Deuces did not need this protection from themselves.

My 06 VW Jetta TDI had a DMF.

They were hit and miss. Right before they went out, they'd start chattering.

I believe most that had failure were swapped out for SMF's.

There is a lot of information about DMF failure at TDIclub.com.
